Hello, I am running Windows 7 (32 bit), and I started getting these BSODs:
"A problem has been detected and Windows has been shut down to prevent damage
to your computer.
The problem seems to be caused by the following file: ntkrnlpa.exe
If this is the first time you've seen this stop error screen,
restart your computer. If this screen appears again, follow
Check to make sure any new hardware or software is properly installed.
If this is a new installation, ask your hardware or software manufacturer
for any Windows updates you might need.
If problems continue, disable or remove any newly installed hardware
or software. Disable BIOS memory options such as caching or shadowing.
If you need to use safe mode to remove or disable components, restart
your computer, press F8 to select Advanced Startup Options, and then
select Safe Mode.
At 5+ years old, I'll suggest changing the CMOS battery as a first step here (or at least check that it is at 3v). It appears to be a memory error but I would focus first on the battery since on many Dell (any pre-built) machines, it going bad can have strange consequences (such as BSOD's)
In asus M4 and M5 series - check system info (windows accessory program) and find last option, error list .. It is easiest way find errors.
There can be line where error is connected to aeappinv2, this mean it is may be failing bios .. This can be anyway fine but it is may be needed to reflash (to version 8, asus tell that is not supported to downgrade and says they don't recommend to do so).
IT ALSO CAUSED ABOUT HEATING what is more usual. I worked several weeks before I find out, that mainboard can get unstable just at 42 degrees of Celsius. I solved my problem after that with couple extra FAN, just one is needed to blow lower side of cpu (put that fan to bottom or left cover to cool chipset and power chips (kernel-power-... errors can be also related to this) This problem will appear when you have very hot processor and devices on case, even have as I had 12cm fan on bottom of 620W PSU). It did not take heat out much as needed and produced it much by selve.
BAD side of this is, my system become quite noisy... So get really silent type FAN... and put much as possible something to kill echo of case when it is something thin metal ... This blow keeps quite much sound.
