computer keeps freezing- hardware problem.

November 25, 2016 at 10:10:01
Specs: Windows 64
I have a laptop and recently it just start to freeze...alt-cntrl-delete doesn't work...I replaced the ram, replaced the harddrive and still it does the same thing? What do you think it is?

First suspicion in almost any "freezing" situation would be overheating. Being a laptop, make sure any exhaust vents/ports are free of blockage and/or dust.

Also check links from Johnw in previous post:

yea, I forgot to mention I took apart the laptop and cleaned the fan out good. That was the first thing. The computer still would freeze so I decided to replace the RAM and HardDrive but it still freezes...do you think it is the motherboard somehow?

"...do you think it is the motherboard somehow?"

It's possible, but the next thing I would think would be virus/adware/malware. Scan for all before proceeding with anything else.

how can it be virus/adware/malware if I replaced the harddrive with a new one and a new o.s.?

Did you transfer anything from the old machine to the new one? Have you visited any websites since the install? Do you have virus/adware/malware protection installed?

Did you clean the CPU heat sink too?

Always pop back and let us know the outcome - thanks

Hi Dee,

I note your comments above regarding cleaning. However, often missed (as it is out of sight) is between the fan and rear of the Heatsink vents.

Because the vents are so close, larger dust particles build up into a thick wad of fluff. and cannot be removed without dismantling the Laptop.

Using an airspray from outside does not work and could be detrimental, as wad is so thick, it could be blown backwards without breaking up and jam the fan. Anyway it would not be wanted inside the Laptop and there is nowhere else for it to go.

There are Youtube videos of this problem.

Good Luck - Keep us posted..

I usually push a small brush through the fan blades into the heat sink which loosens the dust so that compressed air then shifts it. However I clean mine about once a year so this might not be so easy if it has been left for years.

You haven't supplied any info about your laptop - no make/model, no mention of which CPU it has, no mention of which Windows version it's running. I don't know why you would have suspected RAM or the HDD. Even so, they could have easily tested to confirm if they were the problem or not. Which OS did you install on the new HDD & how did you go about it?

"yes I did clean he heat sink..."

How dusty was the fan & heatsink? Generally, all that's needed is a blast of compressed air thru the cooling vents & it's good to go. Mike mentioned a "thick wad of fluff", but if the vents are blown out often enough, there's usually no "wad" & no need to dismantle the laptop. Did you actually remove the heatsink to clean it? Did you reapply thermal paste AND do it correctly? Find your CPU on the list & make sure you used the proper method. If you didn't, you will have to redo it.

yes, I did take the fan and heat sink apart and gave it a good cleaning...I have the computer in safe mode now...I will see if it freezes...

yes, I opened up the laptop, took apart the heatsink and fan, and gave it a good cleaning...that was one of my first actions before replacing the harddrive and Ram

actually, the heat sink and fan was not too dirty.
well, after cleaning the fan and heat sink the computer would still randomly freeze and non responsive to alt-cntrl-del.
I replaced the hard drive because when I was running a diagnostic on it the computer froze multiple times and this is after cleaning the fan and heat sink. I replaced the RAM because I only had 4GB so I upgraded to 8GB for better performance.

the computer is a pretty old one. it is a HP Pavilion g7-1075dx notebook Pc. Processor: Amd Phenom(tm)II p650 Dual-core 2.59 Ghz
I have windows 10, 64-bit and I installed it via c.d. which was relatively self explanatory.

I asked about the OS because OEMs such as HP no longer supply Windows discs. The user is expected to create discs from the recovery partition & it seldom gets done. I wanted to make sure you didn't clone the HDD just in case a virus was causing the problem. Also, the proper thermal paste application for a Phenom II P650 is the "surface spread" method.

I'm guessing you didn't have this problem prior to Win10. How long after Win10 was installed did it begin? Being that it is an older laptop, installing Win10 might not have been such a good idea. HP doesn't have any drivers for it so you either have had to hunt & peck to find what you need or rely on Microsoft. There are no drivers available from AMD for the Mobility Radeon HD 4250 graphics, so I'm guessing Windows loaded generic ones. If you have the time & are willing to experiment, try reinstalling Win7 64-bit & see if you still have the problem. Or try booting off a Linux Live CD/DVD & see if the system will run without any issues. If it does, you'll know you have a Win10 problem, not a hardware problem.

It is important to use the exact specified method for applying thermal paste - too little or too much can cause issues. But lets get this overheating behind us. Run this program and let us have the temperatures:

EDIT:
Assuming it holds up long enough to run the program.

actually, the problem started before I changed the harddrive. the original harddrive had the factory installed o.s. of windows 7. Once it started to freeze I cleaned the heat sink and fan...it still froze...so I brought a new harddrive and oem windows 10 c.d. I also upgraded my RAM from 4GB to 8GB..and it is still freezing that is why I am thinking it maybe the motherboard...

where are the temperature reading after running the program?


I found the readings... current cpu= 53.5c, min=51.1c, max=59.0c

Re #19

Thanks. From what you've given I don't think overheating is your problem.

EDIT:
I take that back as later it seems the readings might have been taken before it had warmed up.

I did let the computer run for a while and the current temp now is 65C.

"the current temp now is 65C"

Laptop CPUs tend to run hotter than desktop CPUs because they don't have the benefit of the space needed for a large heatsink & fan. That's why it's critical to apply the thermal paste correctly. You never did answer how you did it & what brand of paste you used. Hopefully you did NOT re-use the old paste. Regardless, it seems like you're going to have to tear down the laptop again & redo the paste. Make sure to remove ALL traces of the old paste from the top of the CPU & bottom of the heatsink. Sometimes the heatsink also sits on other chips on the board. If that's the case, those will have to be cleaned as well. Use the "spread method" as shown in the link in response #11. The spread should be paper thin, do NOT spread it thick like frosting.

Make sure you check with the CPU manufacturer and apply the thermal place exactly as per their recommendations. It is important and probably where you went wrong.

hey guess,
First off I want to apologize for not following up on my laptop situation and I want to personally thank all of you for helping me out.
Now, about my laptop...the last opinion I got was to make sure the heat dope was applied correctly to the cpu...To be honest, after I was told that I went to the store to purchase some and when I got back and turned on my computer it seemed to be working fine. I haven't had a problem since...
Happy Holidays everyone and thanks again for helping me with y'alls technical knowledge.

Well maybe what you already had has bedded in at last. However you now know what to do if the high temperatures come back again.
