Well My wife gave me that look the other night when I was playing around with overclocking our computer. The good news is that we have two (both are old) so its not all bad. But bad enough. Here is what happened.

I overclocked my cpu for the first time in my life, the computer started up okay but I noticed it was heating up faster than I was comfortable compared to the original setting. So I knocked it down by quite allot. back and forth a few times with no real problems to note. The last time I tried I put it at 114hz and rebooted. system began to start up but froze. I rebooted HOPING it would at least get me to the Bios screen but no. Now it wont start. I opened it up and found that my Graphics cards fan was dead.

Here is the question. Could changing my front side Freq have cooked my graphics card? The specific freq of 114hz messed everything up and its all dead? Murphys law that the card just failed at this moment?

Mother:Azza KTA3-AV
Process:900mhz AMD
Card:RIVA TNT2 VA-235
 
1. You could have cooked the vid card but i doubt it
2. 114 isnt all that high even though it does cross the magica 37Mhz PCI divider line
3. I have NEVER EVER heard of Azza before
4. While overclocking may not kill the vid card, a dead fine might. Then again a TNT2 shouldnt be hot enough to overload passive cooling :)
5. Reset the BIOS
 
AHHH if all else fails READ the help file on the manufacture website. DUH.

It recomended resetting the CMOS. Once I tried that it started up right away :) But it says CMOS checksum error... what does this mean?

The 37Mhz you mentioned as the limit. How do you calculate this? what is the bus speed I should stay under?
 
CMOS checksum means that you just need to reset the CMOS values and make sure everything is ok.

It should be 37.5Mhz. Why? Because it is that way. LOL
