Windows 7: Various BSOD errors during normal use and sleep

08 Feb 2013   #21

Windows 7 Home Premium 64bit

I replaced the CPU and waited to see if I would get a BSOD. I did get one after about a week of use, and I am attaching the dump if you want to see it. This is a fresh install of Windows after the new CPU.

I ran Prime95 again with both tests. The Large FFT test lasted much longer, lasting 4 hours before I stopped it manually. With Blend, 1 core failed after 1.5 hours and the other ones are still running 2 hours in. Edit: I finished up Blend. The last core failed after ~9 hours. I'm running a longer Large FFT test now. Edit 2: I ran Large FFT for 10 hours with no failures.

Should I go ahead and warranty the motherboard? The new CPU did change the Prime95 results, so maybe both the motherboard and CPU are bad? The PSU is a few years old also, but I haven't had any problems with it before the new hardware.

If Large FFTs is working fine and Blend isn't, it means there's a problem with crosstalk between CPU-to-RAM, meaning either the RAM itself is bad or the motherboard.

Concerning the PSU, just remember that PSUs degrade in wattage output during their lifetime, and the rate of degradation varies depending on the quality of the item. If you got a more economy/budget PSU as opposed to a higher priced one, the parts in it are going to be cheap and will degrade faster than higher cost items, as well as has more potential for spontaneous failure. Your PSU may have worked just fine with your previous setup, but the new hardware may be taxing it beyond its current capabilities. That's why a good habit to get into is to purchase a high quality PSU always, and the wattage for such should be around 100-150 watts above what you anticipate the highest load of the system will need. That way the PSU can degrade and still have room left to spare to support any workload thrown at it for a good long while.
