something strange...

Well today since I had zero to do like every single fucking weekend, I decided to open the PC up and clean it out. You know just the general stuff... remove the fans and clean the dust from them, removed the front intake fan since its not neceassary and only makes the dust accumulate faster and took a spray can and sprayed everything out.

Upon plugging it all back in I notice that the fan on the ATI doesnt idle down but stays on full speed and the computer doesnt post at all (atleast from what I can tell on the monitor. I shut the power off and try it agian, nothing.... one final time and it fires up like nothings wrong.

Im going to shut down and reboot a few more times to see if I can get it to do it again, but this is strange....

I did just update to catalyst 6.8.... maybe thats it.

Well... cant be conclusive since it hasnt happened again.

Ill have to prime 95 over night, then do a loop test with 3Dmark01 to stress test the GPU and then memtest86 to test the ram.

If those all check out then I guess its a problem where the GPU has no power for a while.

so the PC doesnt POST and the GPU fan is on max.. the GPU part sounds normal, my 7800GT's fan doesnt power down until the driver loads

lol whatd you do for it to work again

Just held in the power button until it shut down and then restarted it.

The GPU fan always comes on full blast, but dies about 3-5 seconds afterwards. That time it didn't, it just stayed on. I think I say a red error led lit on my DFI board but before I thought enough to check it I was already resetting the power.

Im going to turn the system speaker back on, that way I can hear the little beeps and what not so I can use those to diagnose problems.

So far the system has memtest86'ed for 10 hours now with no failures and zero errors. I left it on while I went to work, when I get home it will be close to 20 hours of memtest. If i dont have errors by then I can safely rule out the ram.

nearly 3 complete passes of memtest86 and zero errors...

It ran from about 1 A.M. EST this morning to 7 P.M. EST with no problems what so ever.

Going to do a Super PI while I watch the packers game and then loop 3Dmark01 while I sleep.

Ok so the 3Dmark01 loop had an error before it even got half an hour.

I want to give the card the benifit of the doubt and blame the program... is there any other good GPU stress test apps out there?

No... but I looped 3Dmark01 again for probably 8+ hours with no issues. I dont think the GPU is bad.

So my only guess would be the power supply, or maybe because I drained the capacitors by pressing the power button when I had the case apart and the power cable was removed from the machine(its a good idea to do this however...).

Im not getting POST error codes, or any red error LED's on the DFI board itself so inono lol.

lol yup, first thing i do for any non-windows problem is press the power button with the PSU switched off or unplugged.
probably best idea to ignore this problem until it fucks you again :P
