Rather than concentrate immediately on the video card, consider
the system could fail on you.
1) It could be a memory problem. If you have two sticks of memory,
swap the slots they fit into. (Make sure computer is unplugged,
before changing any hardware.) Did the symptoms change ? Perhaps
the memory is bad. A memory tester, may not be able to reach
memory, which is reserved for things like frame buffer for graphics.
Run memtest86+ from memtest.org anyway, in case some other parts of
system memory are failing. Perhaps a DIMM change, will bring the
system back to full strength, without shopping for a new card.
If you have only one DIMM, run memtest86+ and see if any available
memory is throwing errors.
2) It could be an issue with Northbridge operating temperature. If
the heatsink fell of the Northbridge, or if there was a fan on it
and the fan melted, it could be overheating and corrupting things.
In this case, there is no fan, so that's not a problem. It gets
a little "side spill air" from the CPU fan. http://www.jetway.com.tw/pic/big/K8M8MS.JPG
Verify the push pins are holding the aluminum sink firmly in
place. They're the two "white dots" in the picture, near the Northbridge
You could also do a general inspection of the motherboard, looking
for electrolytic capacitors (aluminum cylinder with plastic sleeve),
which are bulging or leaking orange/brown fluid. If motherboard damage of that
type is evident, purchasing an AGP card might be the last
thing on your shopping list. You might be in the market for
some kind of "upgrade", in which case, all new issues will
emerge. Many new motherboards have decent onboard graphics,
and no card will be needed. And if a video card was needed,
it would be PCI Express (so an AGP card would not be reusable).
If you've done all your homework, and buying an AGP still seems
a logical option, then get a 6200 as an AGP card.
It would have a bit more performance than the built-in graphics
and not strain things too much for you.
