Problem is solved, but i still want some info.
So if you are CPU savy or can provide me a useful link. (Google doesn't like my search terms)
Recently i changed out my Athlon 1800 for a 2200. PC booted and worked fine, but my
temperature sensors showed CPU at 150F at idle. It would easily hit 170 while compiling
or burning a disk. So... i figured the heatsink/fan was too small for the new CPU.
Looking through some old donor boxes i found one with a thermaltake heatsink/fan. At almost
double the size of the original i figured this would help cool better.
After a quick swap i booted up and had no video signal. At first i just thought it was a glitch, i have
a monitor on my test bench that exhibits the same "no video signal" behavior on some machines.
Unplugging it for a few seconds fixes it. I unplug the main monitor, wait, and plug it in. Boot the PC
and get no video, although i can see the HD light and can hear the drives spin up.
Troubleshooting goes: swap monitor, swap video card, put video card in different box (it works),
decide the AGP slot has gone bad (from changing a heatsink/fan) and clear the CMOS. Nada!
Stop by local shop and grab a PCI video card, it fails. Test it in good machine, it works.
Back to Google and have two suggestions: MotherBoard or CPU. Not excited about changing out
the MOBO i swap the Athlon out with a Duron i have in the donor box.
Boot up, lights flash, drives spin, monitor comes on...wo0ho0!
Now i know this is a long read for this simple question: How in heck does a proceesor go bad
in such a way that the machine still boots and only the video is affected? Keep in mind this box
has an AGP slot and no on-board video.
