Hello!

I have an Asus A7N8X Deluxe rev. 2.0 system which has worked PERFECTLY for
over 6 months. Three months ago the problems begun: I had random lockups
while ripping music, defragging my hard disk, playing a game, checking my
e-mail...
The system just hangs and the HDD LED shows activity (though I don't hear
the hard disk).
I swapped my ram, my hard disk, formatted and did a clean install, but the
problem is still here.
I installed a new CPU cooler which has made my CPU go from 58 to 48 C.
AMD ATHLON XP 1800+
APACER 256MB DDR

I have done NO CHANGES since I the lockups came, so it "just begun"...

Any suggestions? Broken board?

Thank you very much!!!

Kind regards,

Hasj Pee

Have you run memtest86 from memtest.org lately ?

Can you run Prime95 in torture test mode for any length of time ?

Is the problem much worse when running 3DMark2001 in demo mode ?

These three tests will help identify whether it is memory, processor,
or video card, as long as you run the tests in the order specified
above. I don't have a good hard disk test, except for you to download
whatever diagnostic is available on your hard drive manufacturer's
web site.
