PC completely locks/hangs up Mark 06-03-07

Hi,

I have recently built a PC. It worked fine for around 2-3 weeks.

After this it sometimes locks up (i.e. no mouse/keyboard response &
cannot ping it from another PC). This happens at seemingly random
intervals and sometimes happens when the PC is not doing much.

It has Windows XP SP2, fully updated and McAfee anti virus fully up to
date. The lock up does not occur every day and not after a consistent
time interval. (Today it locked up after 15 minutes after the first
boot and then immediately after login after the next boot). The
problem did not occur at all for the past four days.
It has only locked up about 8 times in total, but this is too much to
ignore.

It's made of good quality components - Seasonic 430W PSU, Gigabyte
GA965P-DS4 mb, Corsair TwinX XMS2 memory, Intel E6420, Gigabyte
7600GT, 2 x Samsung spinpoint HD. I am fairly experienced in building
PCs but I have never had this problem before.

I have run memtest86 for a couple of hours and no problems there.
Temperatures are fine too.

There are no errors/warnings in the event log. I have updated & reset
the BIOS and installed the latest drivers.

Does anyone know how I can tell if it is a hardware or software fault?

My first guess is the power supply needs replacing.

Uninstall Mcaffee and see if it runs better.McAffee has given me and people
I know more trouble than it's worth.I always recommend get rid f it first
thing on a new PC. Or any other,for that matter.
Also,check your temps.High temps can cause your symptoms too.

I read that the Intel E-6000 series CPUs have a problem that causes
freeze-ups. I have an E-6600 in an EVGA board. I built it last month and had
the same problem. They came out with a BIOS flash that contained a fix for
it. It's been working fine ever since. So, check for a BIOS update. I also
had a similar problem with a machine that didn't have the whole hard drive
formatted. Windows installation only did the first 120 something of a 200
gig drive and left the rest of it twisting in the wind. I didn't notice it
for a week or so and then created another partition and formatted it. That
fixed that problem. Annoying, isn't it. Good luck
