Problems after installing new CPU

[JZA80 Supra]

So i bought a used Q6600 [It used to be in a showroom model and it was never overclocked]
Almost everything is fine, it boots etc.. but it was clocked @ 1.80Ghz and it wouldnt go higher so i set the FSB to 266(it was set to 200 before).
After i did that it gave random BSoD's & it said [dont mind the bad translating] "AMD Drivers not responding and restarted" everytime i opened up chrome and tried to browse.
but when i set the FSB to 260 it was a bit more stable but its still giving me the AMD Driver error

My specs:
Q6600
2GB RAM
Ati Club-3D HD3450
350Watt PSU

Im 100% sure that problem will be gone when you reformat everything(if u need backup do it first) and reinstall your os(usually win7) and reinstall your os.

You can also set the clock speed to normal first before trying to reformat it. If u still encounter the problem, do the steps above.
