Motherboard/CPU problem?

Specs: XP 32-bit
Hello everyone,

I am having an issue with my desktop where
everything freezes, including the mouse, and
never un-freezes.

From boot-up I can use my computer for
anything and everything for approximately 15-
20 minutes with no problems. After that the
computer will usually freeze completely but
never turn itself off. It just sits there frozen.

I have tested the RAM using memtester, a
boot-able test, and the RAM is fine.

I have cleaned the inside of the computer to
prevent overheating. Also, the case is VERY
open and the room it is in does not get all that

I don't figure it is a HDD issue because the
HDD makes no interesting or unusual sounds.

I am starting to figure it is a motherboard or a
CPU issue.

This problem sprung up from no-where, there
were no installations or uninstallations
preceding the problem, and nothing had
changed between when it was working and
when it wasn't.

Thank you for any and all help,

"I am starting to figure it is a motherboard or a
CPU issue" To help you better, we need to know more specifics about the motherboard,
CPU, or power supply(perhaps that's the issue).

Freeze at 41 degrees.

Another symptom: When whatever I am working on freezes,
there are still things I can do for the next probably 45 seconds.
For example I can alt-tab to switch between programs, I can use
the start bar to switch between programs, and I can open the
Task Manager, but not do anything with it really.

When your computer freezes, can you restore it by hitting "Control Alternet Delete" , or, do you have to shut it down with the switch? If you can restore it, it's most likely a software issue. Maybe a legacy program thats not quite compatible, or a corrupt video driver. I would do a little detective work and make sure you have the latest drivers, Also check and see if using a particular program is causing the freeze.

No particular program, Ctrl-Alt-Del does not allow me to do it. I
have to press the button on the front.

Video drivers are up to date.

When this happens and you open task manager what processes are using all the CPU cycles?

How many processes are running in task manager?

That's the odd thing, the CPU usage is usually 0%. Never
ANYWHERE near 100%. Approx 54 processes, the usual

If you have auto update enabled then there are changes to the computer. You might benefit from a system restore to an earlier date. First look at what updates were recently installed.

I would also still suspect the memory. You need to let the test run for a long time (hours).

Boot into the BIOS (setup) and look at the settings in PC Health. Check to see if the settings for throttling or shutting down the CPU are too low. Disable cool & quiet as a test.

One other thing to try. Disconnect your network cable and see if the computer still locks up.

I have narrowed down the problem quite a bit more and feel like it
is so different that I should start a new thread but I will just tack
it on here and hope for the best.

My computer runs perfectly fine until I open any sort of internet
browser. It doesn't appear to be an internet problem, as I can still
play online video-games without any freezes.

It freezes with Firefox/Chrome/IE. So I don't imagine it's a
browser problem.

You may have lots of malware that uses the internet. Check Task Manager when logged onto the internet to see what is using CPU cycles.

Malwarebytes is a good program to cleanse the computer.

CCleaner Slim is also very good. I run it at least daily.
