Computer locking up randomly after 30mis+

March 11, 2011 at 15:25:05
Specs: Windows 7, Core i3 540 @ 3.07Ghz 4GB RAM
I recently made a new computer. I was working fine; but about two weeks ago but it started to locked up, since then it has become more and more frequent. It is at the point now where i am waiting for it to freeze. This has been driving me daft! So far i have ran multiple test and stress test, none of which have helped. They all return with no errors and the system will not freeze during the running of them. When i start the system and play a game i can run it for long periods of time with no freezing, but when doing simple things such as web browsing it will freeze. I have tested each stick of RAM individually and in each slot, both of which work and return no errors. The system will run consistently below 40 C. I Have also fresh installed windows 7 and that has not helped. I think either my power supply is not up-to scratch or my Hard drive is faulting ANY help will be appreciated. (Currently trying the system without my GTS 450 in and using Intel HD Graphics to test if its the power supply failing)

ASRock H55M/USB3 R2.0
450W Power supply (Not sure of the make)
Nivida GTS 450 1GB
Core i3 540 @ 3.06Ghz
500GB Hitachi drive
4GB RAM 1333Mhz (Not sure of the make)

"...made a new computer..." - all NEW parts I assume?

Q: Does the whole system freeze, or just the web browser or applications?
Q: What type of Anti-Virus are you using?
Q: Are you using a 3rd party software firewall? If yes, which one, what version?
Q: Make/Model of HDD?

If you suspect the HDD, you should test your HDD with the free manufacturers hard drive utility available from the hard drive manufacturers website to make bootable floppies or CDs to thoroughly test your hard drive surface area, mechanics and electronics:

- Seagate/Maxtor (Maxtor acquired by Seagate): Seatools.
- Western Digital: DataLifeguard.
- Fujitsu: Fujitsu Drive Test (FJDT).
- Hitachi/IBM: Hitachi Drive Fitness (HDFT).
- Samsung: (HUTIL).
- Toshiba (Fujitsu, Samsung or Hitachi utilities may work).

Thanks for the fast response! Also yes the parts are all new.

A) Yes the whole system freezes, including sound which seems to just replay a stutter sound.

A) Avast, but after re-install nothing. I also had Osx installed but the same problem occurrd.

A) Nope.

A) I believe it's a Hitachi ds7sac500.

I tested my rig without my GFX installed and it still acoured. So I re checked my Heatsink and the one side was loose. I've removed the heatsink and cleaned the dust away. I was planning to buy a new heatsink but decided on the provided one with the CPU. This is a great excuse to buy a new one! I don't want to power the rig on without any termal paste but it's now 1am so I will have to wait tomorrow to go and buy the new heatsink. Once I have installed the new heat sink I will also run the Hitachi software. Thanks again for the information. I will report back when I done those those two things.

Installed a new heat sink... Lower CPU temps but still locks-up.
Updated all the drivers... Still locks-up.
Cleaned the system out... Still locks-up.
Run the HDFT... No errors.
Double checked the RAM... no errors and still locks up.
Removed the GFX card... Still locks-up.
Checked all the cables... Still locks-up.

I haven't got much of a budget to fix this. I have emailed some of the companies that the parts have been ordered from (1 year warranty). But still this has become a major headache! (Froze while writing this out). All I can think of now is ether I have a dud motherboard, my CPU is faulty or my PSU is faulty.

Also I have noticed that it makes a strange clicky beepy sound when it freezes? Any suggestions? as being the weekend I will have to wait till Monday till I receive a reply from any of the companies and my computer is almost unusable at this moment in time.

Cheers in advance; Brennen.

dunno is it just me or your power supply is too small?.....i did a power supply estimator with your spec and came up with a 334 watts power supply.....i am running a 3 year old rig Core quad on windows 7 pro 4 gig ram a ssd hard drive with 2 other conventional hard drives and an old ATI 4870 and a 650watt Thermaltake power supply and never had any lock up what so ever....cpu runs a cool 34C and vid card 39C

Yeh I thought that maybe my PSU was underpowered! I plan to buy one tomorrow, any suggestion to what 'watt' to get? This supposed 'cheap' build might soon become expensive!

Its the random time event of when it happens that annoying me! I just can't work out what the problem is!!!!

If you do not buy a brand name, choose one with the highest wattage possible, too much never hurts...if you buy a brand name(Thermaltake,OCZ,Corsair) you could go for between 500-600 watts, in my own opinion brand name tend to be more stable power supply, and usually are under warranty longer.

I did not have time to go but a new power supply today but after getting back I have checked the cables on the power supply and there is a pin missing in the 24 pin connector is that the problem? http://oi52.tinypic.com/dr9rbb.jpg

That's an NC...(or not used) in that 24 pin specification, so, that's normal.

Did you check your MOBO for bad (even slightly bulging) caps?

Another thing you should do is run your machine in safe mode for a while to see if it freezes. Freezing on Safe Mode operation usually points to hardware issue.

Also, when you test RAM, you need to really test it thoroughly - HOURS n HOURS!

I ran the Memtest, the bootable version and lest it run for two hours, it did 5 passes and returned 0 errors. I then checked the motherboard for popped or leaking caps; as far as i can tell there are none. So i decided to run the system in safe mode (with networking) and have been doing mundane tasks, checking emails, watching youtube videos and just general browsing... i have been doing this now for just coming up-to two hours! and no freezing =). So i have decided to write this post now to ask for help. (Lets hope it dosen't freeze after) I have checked many online PSU tests and they range from 350-510, does this mean my PSU is underpowered? I would say is it a software issue but even after a fresh windows install it freezes and like i have mentioned i have installed mac OS X and the same problem is occurring (Haven't tried linux). I have also ran this system using the on-board HDMI and my GTS out; even then it freezes.(Currently my GTS is in while in safe-mode) So is this a PSU problem? or something deeper?

One useful purpose of Safe Mode is to try to isolate Hardware vs Software issues. If it was a PSU issue I would think it would freeze up or barf even in Safe Mode.

Thanks for all the help PC GEEK and others. I brought a new motherboard and it has fixed the issue! Had to wait for it to come in the post, but the system is now running better than ever! Thanks again! =]
