I would like to overclock my GPU, to get better gaming performance, since I get fine GPU temperatures. 42 degrees after 5 minutes MSI kombustor full load.
However, when I overclock using AMD Overdrive built into catalyst, or MSI Afterburner, by any margin, it blue screens every 20-200 ish minutes, with a kernel 41 power loss in the Event Viewer, and random blue screens with different codes each time, such as the attempt to reset display driver failed.
I suspected it was the voltages, it lets me up them in Overdrive (standalone software), but not afterburner, even after enabling the features, in the config/menu.

My stats are:
AMD Athlon II X3 455 (Deneb) unlocked to quad core and L3 cache, overclocked to stable 3.8ghz
6GB DDR3 1600 RAM (No errors or problems)
ASUS M5A78L-M LX motherboard (the first one)
HDD
SSD with Windows 7 64 Bit
4 Case fans on CiT Recon ( I didn't know what I was doing when I bought it)
XFX Radeon HD 6750 ZMFR (700Mhz clock, 1000mhz memory with GDDR5)
Corsair CX430M modular power supply.

So any ideas people? Thanks a lot

Could be the card, could be the power supply, could be your overclocked CPU. If I was you, I'd just get a faster card.
Why? If the card causes crashes when you try to overclock, you can easily kill it or the motherboard if some electron decides it does not like you looking at it funny. If the issue is power supply not working quite right with sending voltage to the card during the overclock, you will need to spend about the same as a new video card anyway.

The 430 watts should be plenty to run a faster card although the overclock on the CPU will be drawing more power.

A Radeon 7770 is not that much cost (in gaming video card land) and is a lot faster than the 6750 would be even with overclocking it to the point of death.

Agreed, although I will say that it is not the PSU, since I got it on Monday and my old one had the same issue. I will probably wait until higher end cards come down in price, like the 7850/7870. Thank you
