Help Please! BSOD.

I know that Machine_Check_Exception, according to MaximumPC, has to do with a bad or too aggresively overclocked CPU OR a faulty PSU.

Sooo, are you overclocking your CPU? Even after changing the PSU you are still getting the error I assume?

If so, you might try testing the PSU in a different computer if you can.

One thing you might try is removing nonessential components (things that aren't required to boot into windows like your soundcard, all optical drives and any secondary HDDs, floppy drives, USB devices, etc) and try booting into windows. If successful, then add one device at a time.

Nothing in the box is overclocked, with the exception of a factory overclock on the video card. The information i can find on the BSOD error is that its a hardware failure. The thing that boggles is me is the BSOD is not intermittent as i would expect from a heat issue. Also, if i load my old underpowered PSU in, windows will boot up just fine. Ill try restetting the CMOS, though im perplexed, and dont expect it to fix the issue. Also im only attempting to boot with memory, hard disk, and video card. My sound card / optical drives have all been unplugged / disabled. I cant seem to understand how the PSU alone can cause this BSOD... especially when i can get into safe mode just fine.


Thanks...

Try to disable onboard devices, network card, raid, sound card, parallel and serial ports, fire wire, etc. I had similar issues with one of my Asus boards and it turned out to be build in network card. After I disabled it system ran fine, just had to add in PCI adapter. Just my $ 0.02.

Plug your old PSI back in temporarily, you neednt screw it in etc just sit it next to the case. Does it work then?

If so, RMA the PSU. There is no way it should fail with that after working with the old one!

If not, then you may have other problems I'd try underclocking the RAM and CPU one at a time, to see if that makes it boot.

IMHO 430W PSU should be enough for your set up. Maybe you just got a bad one this time. Did you check voltages in BIOS, to see if they are stable. They should be no more than +/-10% (thats pushing it) out of range. Also it's possible that something goes wrong when you put some load on that PSU, and voltages drop causing you puter to crash. If everything works fine with your old PSU, I would just return this one. Good luck, I know it can be a major PITA.
