Hi,
I have a problem here with one of my WinXP SP2 computers. The machine suddenly freezes without a warning, no log - no nothing. I have to reset it manually to get it back working again.

I really have no idea what it is.

Is there something (program) I can do to get some sort of a log to know what's causing the problem?

I had a similare problem with another computer where the CPU fan didn't work, but everything seems fine here. The only thing I can see is that the +12v power sometimes goes up a little above +13v.

Cheers,
Andreas

Have you cleaned out the inside of your computer lately? Heat is a killer of computers. If the CPU fan gets clogged your motherboard may auto shut down to prevent damage to your CPU.

It seem to me like overheating problem.

Do you have any software that is able to check your current temperature of your CPU ?

If not, try using Motherboard Monitor to check your current temperature.

What's your current spec's of this PC ?

It is a hardware problem, pretty sure. I just ran Memtest-86 (booted from a CD) and it got to 95% without a single error when the machine suddenly froze. It had then been running for almost 6 hours.

I have software to monitor the tempareature, but it doesn't seem high at all to me (CPU from 30 to 45C and system around 30). I have even opened up the side cover and have a table fan blowing fresh air straight into it.

System is:

Intel Celeron 2.6Ghz
1Gb RAM (2x512)
MSI-865GM3-FIS mainboard
2 S-ata harddrives
1 IDE harddrive
DVD player
DVD burner
Pinnacle AV/DV card

Running WinXP Pro SP2.

Cheers,
Andreas

It does sound HW or possibly driver related.
Next time it hangs on it own without it doing much of anything, check the applications tab in task manager just for the heck of it to see if anything is listed as "not responding".

The Event Viewer in the Administrative Tools may also shed some light on the problem.
Do you have any USB devices plugged in? Especially All-in-one printer/fax/copiers.

The machine also freezes when I boot on a DOS CD (memtest-86) so this is not Windows related obviously. The first thing I checked was the application event manager in WinXP. Nothing special there either.

No USB devices are connected at all.

I suspect:

- CPU
- Mainboard
- Power Supply

It could be a failing capacitor on the motherboard. Near the CPU there are several small cans like items about the size of pencil erasers. The tops should be flat and the sides smooth. If the are bloated that may be you problem also. If remeber correctly Advisor usasma knows about a utility that can test the capacitores on the motherboard. I seemed to have lost it. Contact him about it.

Hi Andreas!

I hope this is the link that Acklan was referring to:

http://badcaps.com/ident/

Did you check the System portion of Event Viewer for errors also?
Did you search your hard drive for any files ending in .dmp?
How 'bout any recently created .log, .bak, or .txt files (or any recently created files for that matter) - around the time of the last crash?

Otherwise you'll have to strip everything that you possibly can off of your system and then try the DOS/MemTest disk (PSU, mobo + cooler, 1 stick RAM, vidcard, keyboard, floppy drive). No mouse, no hard drive, no CD or DVD drives, no extra fans, no TV card, no nothing else!

This will limit the problems to the components that are attached (if you have more than 1 stick of RAM, you'll have to test with each one separately). Then borrow what you can to test the few components that are left - what you can't borrow, you'll have to buy - so try and make sure you can return it if you don't need it.

Swapping the RAM will also help to tell if one stick or the other is bad - then you can go from there.
