May 6, 2013 at 07:46:48
Specs: win xp sp3, 2.80Ghz/2 Gb

CPU usage increases to 100 % while browsing with both Google chrome and Mozilla Firefox and it is very irritating and I am not able to sort it out ,

pls help me.

my system configuration is win xp sp3 2gb ram and Pentium 4 2.80Ghz processor

Previously there is no such issue but now this is very irritating

I want to ask you is it because of many plugins installed or there is some other reason

Boot into safe mode & run a full (not quick) scan for viruses & malware.

Did you scan with Malwarebytes as well as your antivirus program?
Clean out browser's History, Cookies, Temp Files, etc.
Do a Disk Clean Up.
Uninstall programs you do not use, especially ones you may have recently tried or downloaded but are not really interested in.
Run msconfig, go to Start Tab and uncheck all except Microsoft and your antivirus program from starting with Windows (you can later add back any you find you need), Apply and restart the machine.
What antivirus program do you have? Some antivirus programs can be this cause (we call them system hogs), especially on older systems and just after an upgrade to a new version or even an update.

I have once try to scan with malawarebytes but it almost freezes my system and with grt difficulty i got rid of it.I have already done like clearing out temp files,cookies,caches and i have already done disk clean-up and disk defragmentation.I have already tried ccleaner for registry defects.

Right now i am using avast anti-virus and i have not updated to latest version which is compatible to window8.
and i don't think that avast is culprit because i have never seen him using 100% cpu cycles but many times i have seen avast using around 50% of cpu cycles.


But one thing i want to bring in to your notice that at the time of re-installing the pc when i am facing similar problem.I feel for sometime the problem is solved and

one more thing is that at the time of re-installing win xp sp2 previously the system auto-matically shut-down.

And after booting when i even open any drive, the system freezes for few seconds and i not been able to navigate inside the drive and not able to open any folder and at that time the cpu usage does not go high as 100%.

Avast is good, but to keep it working well, you need to update it to the latest version and keep the updates on automatic (or manually, at least weekly). Avast, in prior and even the newest versions works well on P4/XP combo, though you may find some times when updating or scanning will slow things down a bit on the single core CPU.
Freezing and CPU usage climbing together is typically a sign of malware and since no protection can be 100% effective 100% of the time against 100% of the nasties that are out there, you need a supplementary scanner at times like this. I do not know what your prior experience with Malwarebytes was, but it is possible that the problem you came across might have been the malware interrupting the install or starting of the program, and that might have been the issue. I have had good results using Malewarebytes on quite a few systems. Restart the system in Safe Mode with Networking, Download a new version of Malwarebytes, Install, Update, and run it (all in Safe Mode) to identify and remove the issue from the system. Then restart in normal mode.

what do you think @fingers about auto-matic shutdown of computer at the time of installing the win and what do you think it might be because of over heating and if yes then how can i confirm about the same.


one more thing i want to ask you fingers that many plugins are installed in my browser it might be possible that they are causing 100% cpu usage when i am surfing the internet.

Note that XP does restart once or twice during install, but if it just shuts down, especially if it does not pick up the install at the same point, you may have a hardware issue. Test your memory first with a bootable CD you prepare with Memtest on it by booting to it. This is also good to identify hardware issues, since it operates outside of Windows so any problems cannot come from Windows. Run Memtest through all tests, no errors are acceptable. If errors or if it freezes or restarts, retest with one stick of memory at a time to confirm if the problem is with the memory and which one. Replace as needed. Once you can confirm that your memory runs without errors, test your hard drive with a bootable CD created with the DOS version of your hard drive mfg's test utility, run the longest test available. Testing with the utility from your hard drive mfg. is best, but Seatools from Seagate will work on nearly all conventional hard drives. The hard drive utility will repair minor errors it finds, but many small errors or something major will mean replacement of the drive is indicated.

Please note that neither of these will in any way effect the CPU usage, which was your initial question. This is noted so anyone reading this will not confuse these tests as having anything to do with your initial issue/question, but the
shutting down you experienced during Windows installation and possibly other stability issues with Windows.

Without knowing what plug ins you are using, we cannot tell this, but it is possible that even one plug in can do this, if it is poorly created or is designed to cause problems (like malware is). To test this, just disable all plug ins and then reactivate just the ones you use once you see the results of the test. Use add/remove programs to permanently remove anything you do not want/need. I recommend the minimum amount of plug ins for comfortable browsing, even for more powerful multicore systems.

Again, if it does not test out that it was caused by a plug in, uninstall nearly everything that you do not use and run Malwarebytes in Safe Mode because you most likely have something there.

If this does not prove the case, then i must suspect that when you reinstalled Windows XP, you did not begin by deleting all partitions on the hard drive and creating new partition(s) before installing Windows, which might indicate that you had a Root Virus that survived the reinstallation (hence the name 'root') in some small way and is still there, slowly working itself deeper through your system again. If this is the case, the best solution is to delete all partitions and start over. ((Install Disk>Custom>Partition/Format....))

You can check temperatures in your BIOS or install HWMonitor for real time temps. Post temps at idle, after 15 minutes general work or browsing, and after 15minutes intensive use (games, video, multitasking, etc). Remember that temps for P4's tend to be higher than many other CPU's (exact CPU model would be helpful for this as well).

Understand that until you manage to control CPU usage, you are going to have a higher than normal CPU temperature since the usage will be constantly high rather than getting a chance to cool periodically as would be normal for normal usage.

Post the actual numbers in degrees C. Anything else it too vague to be useful.
The minimum and maximum are the lowest and highest that it recorded since you started it. The other number is the actual one at the time you are looking at it.
To test the hard drive I recommend only the hard drive manufactures test utility of your actual hard drive, or if that is not possible, use Seatools from Seagate since it is a reliable and universal program.

fingers is it possible because the cpu cooling fan is not able to cool properly as i doubted because of that the inside temperature of system increases causing airflow temperature of hard disk reaching threshold and that's why hdtunepro is suggesting for replacement of harddisk.

Most desktop systems of that era use one CPU fan to cool the CPU and a case fan to exhaust hot air from the case plus the power supply's fan also exhausts hot air from the case. Some older systems (usually P3 and before) used a CPU fan and only the power supply's fan for exhaust and at least one system I have seen (P4 era) used a CPU fan ducted to exhaust and the power supply's fan to supplement it.
Whatever the system, you need to make sure that your fan(s) are running.
It does not pay to discus this further until you post the actual temperatures to show if, what, and how much the heat issue is.

hdtunepro show airflow temp-51 and seatools for dos shows current temp 48 (after 40 min. the current temp changes to 52)and poh-3426 and in long test it shows only 1 error.

It passed the logt test after repair.

Now i don't think there is a need for change of hard drive.

what is your views for hdd replacement and explain me about airflow temp shown by hdtunepro.

Seatools is able to repair bad sectors, mainly by telling the hard drive that those sectors are off limits and not usable. This is good for a single or a few bad sectors, but if you have more than a few or if they appear again, it is time to replace the drive. Keeping a back up of your files is a good idea in case the drive get real bad real fast.
I am not familiar with hdtunepro so I am not sure what they mean exactly, but combine the reference to airflow to the fact that your hd temps are high, I conclude that you do not have sufficient case air flow to cool your system.
I asked for ALL temps from HWMonitor because this would be even more obvious with them. Please post them. My HD's run around 30 C so yours are hot. Also list how many fans you have, their placement, and the direction of the air (intake/exhaust) and any locations were possible fans may be added (. These together will help determine your solution. This does not mean that you should run out and add many fans (too many or the wrong placement is worse than not enough), just supply all information for the best help.

@fingers as per your request I am pasting the data of hwmonitor and want to tell you that at the time of starting cpu hdd temperature is 38c but within 15-25 min it reaches to 46c.

now pls tell me what to do???

In total there are only two fans in my system(as per my knowledge) one in smps and one above processor.I don't understand why it is showing so many fans.

I want to ask you one more thing that in your last reply you have mentioned that your hdd runs around 30c but i want to ask you that it is might be you are living in colder area as compared to my region.

A screen capture of the HWMonitor readings would have been better, especially since you have not clearly identified all numbers as well as you could have.
A modern computer should have a rear exhaust fan (high up in the back) as well as the power supply fan and for systems with multiple hard drives, powerful graphics cards, or warm climates, a front intake fan (low in the front) is helpful. This is assuming a top mounted power supply, for bottom mounted power supplies, it may be needed to add an additional top exhaust fan or swap out the rear exhaust fan for one with relatively high CFM's. Never use side fans since they interrupt the air flowing smoothly through the case. This will be the same for nearly all climates since in cold climates, there is heat being used in the rooms and most hot areas use air conditioners in the warmest months. Visually confirm your fan(s) are working, their placement, and orientation. The temperatures that you are showing are on the warm side so consider seriously adding at least a rear exhaust fan of a high quality to improve air flow (nearly all cases have a place at the rear for a fan to be attached over a vent, this was pretty standard all the way back to the 1990's, my Pentium 166 system had the spot and I added a fan, as for most systems since the Pentium 4's and later, they should have come with one). Make sure that fans are connected through the motherboard (as long as connectors are available) for your BIOS to monitor and control the fans as needed.
What did Seatools say about your hard drive? If it says to replace the drive, replace it. If not, additional cooling may help things. drives included.
More detailed information on your system would have been very useful from the beginning.

Your case appears that it may be a compact design case (hard to tell from the image) which is not very good at cooling and if you actually have one of the Prescott Pentium 4's, they tend to run hot, you may find it difficult keeping it cool, but look into if there is a spot for adding the exhaust fan.
It is possible that the voltage to your CPU and chipset are higher than needed (generating additional heat) and manually setting them lower by a very small amount in your BIOS may help with your temps. Your CPU temps do not show up so I have to assume that it was made before the processors commonly included the thermal sensor, but I must assume that it also is hot too.
If adding a fan is not an option in your case and you are not going to be up to replacing the system anytime soon, consider either a new case to move the system into, or a cooler running Core 2 CPU like the E7500 (your motherboard supports this) if you can get decent price on one, or better, both.

but before all that discussion i want to ask fingers that right not the fan above the processor is not original intel one but installing the original intel one can help me according to you.
And you are right the case is compact as compared to previous one. but I have replaced the case around a year back. along with the processor cooling fan.

HWmonitor does not show CPU temperature, just motherboard and HD temps.
Your VCore is your CPU core voltage and though it is in range, your processor might run with it slightly lower. I forget which is the chipset voltage off hand, but if it could tolerate a bit lower, it too would generate less heat. This might require a bit of experimenting though.
Your CPU heat sink/cooler is of the OEM style so I do not know why you have changed it as most of these type are not as good as the Intel ones. If you were going to change it, you should have went with a better one or else remained with the original one. I am including a link to instructions for resetting the heat sink with a new application of thermal compound:
http://www.arcticsilver.com/intel_a...
This will not help the overall temperatures (motherboard, chipset, southbridge, hard drive, etc), they will need an exhaust fan and probably a larger case with a front intake and a rear exhaust fan to make a difference.

I am not sure how we ended up here from your start, but I hope that that is no longer a problem other than the heat which will continue to effect all of your components.

"why are you asking this question"

Because if you built it, you need to fix it. If you bought it pre-built from a store or computer shop & it's still under warranty, take it back & have them fix it.

I notice there's no exhaust fan in the rear of the case. That's one reason your temps are so high. It also looks like the CPU heatsink might be dust clogged, so that would be another problem. The heatsink itself may need to be removed, completely cleaned, then reinstalled with a fresh application of thermal paste. And the paste MUST be applied correctly or the CPU will run hot. And just to clarify, CPU = processor, not the computer tower & everything inside. Your CPU is a P4.

There's no way the system will run correctly if the voltages are out of whack. Just take a look at the ScreenCast you posted - the +3.3v is acceptable but the +5v is only running at 3.6-3.7v & the +12v is only running between 5.6-5.8v. You'll never get stable performance with that power supply. The Zebronics ZEB-450W is cheap low end garbage & needs to be replaced ASAP. My guess is you're from India? I don't know why, but the computer people in your country seem to have a poor understanding of power supplies (aka SMPS).
