Intermittent problems are the most difficult to diagnose, especially without
a chance to swap components.
Suggestions:
1. When you turn the system on, does the problem appear soon after, or does
it take some time before it appears.
2. Does the problem ALWAYS occur at some time during a computing session of
at least several hours.
3 Does the problem seem to be related to system temperature?
4. Try safe mode. This will bypass the driver.
5. Try booting to the BIOS setting pages. Does the problem occur while
looking at various BIOS setting pages and changing settings (don't save the
changed settings.)
6. Borrow an AGP card know to be good.
7. Buy a cheap AGP card (a XFX GeForce 5200 128 MBytes is ~ $25 US.)
I would guess that from your description you give and the bad results when
displaying the BIOS screens that the memory on the video card is faulty (the
problem gets worse when scrolling and the problem is immediately apparent
when first booting. You don't mention gaming, Vista, gaming or professional
graphics programs, so you probably will be fine with an GeForce 5200 128
MByte video card. And your CPU might be the limiting factor anyway.
