Halmacpi.dll/ntkrnlpa.exe BSODs on fresh Win 7 install

[Galhast]

Driver was downloaded and installed on Monday (nz time). Just had my first blue screen since then: kernel_mode_exception_not_handled (8e), in stack was halmacpi.dll, ntkrnlpa.exe, win32k.sys. Kdcom.dll, mcupdate_authenticamd.dll, pshed.dll, bootvid.dll also mentioned.

The same minidumps are being created again. Maybe the power supply is causing this...

I'm really not sure. The PC itself was purchased around july/august of last year. In November, my brother gave me a handmedown ATI video card, after that was installed the computer started turning itself off. Attributing it to the low watt psu, I upgraded it, but instead of fixing the problem it just started blue screening instead, referring to the atikmpag/atikmdag.dll (ati catalyst control center) files.

I've since purchased the nvidia card/reinstalled OS, still getting daily BSOD's, so probably there was nothing wrong with the ati card. Or the PSU.

"Attributing it to the low watt psu" What is the make and model of the replacment power supply?

You might try replacing the video card once more

 

[Galhast]

With the original ATI or a third card?

 

[Tmagic650]

If the ATI card ran with no BSOD's try it. If you had BSOD's with it try another third card
