Darkhaze I pulled the shroud and fan and vacuumed out lots of dusts for a little thing, it's a bit quieter but, an x600 (as it turns out) is much weaker than the igpu of the weak mobo on the old system I just picked up for dirt cheap, and apparently i didn't give away the x4 965 i thought i did so it turns out i can build two systems now, but I require the amd2's case. I'm gonna sell the old girl for $20 as it seems to work just fine again, it will live on!

Kryton Sounds like a GPU issue alright, at least now you have a clue and that's something to work with.
GPUs like the 8800GTS are cheap and all over the place, shoudn't have a problem finding one.

Well I was going to tinker with it, but I had to have a system in place of it so I went and spent $100 CAD on a 1090t w/16gb ram and gtx 460 +psu hdd etc, I put the x550 gpu in the 1090t system and it's fans were still at 100%. I put the gtx 460 in the problem am2 system and.. everything started at 100% and then both cpu fan and gpu fan settled down and became normal. ???? i don't know what's going on. Last I tried the 8800gts in the 1090t system and still no video and 100% fans...

Bottom line, I also found an x4 965 be i thought i had given away and now i can build 2 complete systems, 3 if I baking the 8800gts works or I get another gpu.

Did this issues occur together or what? What is the timeline on these issues? How long has the CPU fan been going 100%?

What do you use this computer for? Are you just trying to keep it alive out of nostalgia or do you actually use it for something?
The fans both went to 100% and stayed there at the same time, blowing my 8800gts, even though it's fan was at 100% with no video. This was a week ago. It's an old ppl email/ms word computer.

I actually have my nh-d15 low noise adapters sitting in the box lol, but that's just a band-aid, not a fix. wouldn't matter for the gpu either

Make sure your CMOS battery is good because a weak battery can make a system do some weird stuff. If the battery is over 3 years old go ahead and replace it to be sure before doing anything else, if you can pop it out and check it's voltage with a voltmeter. You'd want to see 3.0v's or so with it, anything below 2.9v's is bad and needs replacement.

Although not likely it's possible you may need to reflash the BIOS, something could have gotten corrupted when the issue occured - I really don't see how but it's a possibility.
Related to the above a weak battery CAN cause corruption of the BIOS.
