Ok I was using my PC the other day and I wanted to try overclocking my phenom 2 x4 810 so I went into the bios and set my options I set the HT to about 252 and CPU to 1.45v, left the RAM at the stock 1333 speed.
Now before I overclocked I noticed the letters on the bios screen were shaking slightly I just shrugged it off as "whatever I guess the bios does not have drivers".
after making the changes I rebooted and windows gave me an error about a missing or corrupt system file so I changed everything back to stock and tried booting again.
After returning to stock windows still would not boot so I popped in the install disc (Vista x64) and it brings up the "Windows is loading setup files" and once the progress bar filled up the system rebooted.
I have tried using a different PSU, RAM from another machine that is running fine, moving the RAM to the other slots, loading the Windows install disc with no HD attached all with the same results.
the motherboard is an Asus M4A78T-E, I have had it for 2 years, used it for about 10 months then upgraded to an i7 so I put the MB in the box that my i7 MB came in then last week I decided to build a spare PC using the old CPU and MB combo I had put away.
does this sound like I burnt out my CPU while trying to overclock or the motherboard went bad?
I can get as far as windows asking me if I want to load normally or safe mode ect. or if I load the install disc the progress bar fills up then reboot. I can still get into the bios and change settings if I want, I even tried to manually setting stock values for the CPU.
