Have you scanned for malware lately?


This: Halmacpi.dll is the Windows HAL (Hardware Abstraction Layer)

Caused this to crash:

ntkrnlpa.exe

Gathered info:

Ntkrnlpa.exe is part of the Windows Kernel as are Ntoskrnl.exe and ntkrnlmp.exe. These files install as part of your Windows NT/2000/XP/2003 operating system and are needed at boot time. You'll find them your Windows\System32 folder. Trying to disable or remove these files could have undesirable effects. You'll find more information at http://support.microsoft.com/kb/887675. You'll find information about a vulnerability in the Windows Kernel involving these files at http://support.microsoft.com/kb/931784.

[out of date info somewhat since 7/8 aren't listed but....]

If the kernal gets corrupted, you can try a system repair, info is in tutorials, if it fails you have to wipe and drop a fresh 7.

But I'd be checking for malware before going there plus it could be RAM causing issues, and without checking that first, no amount of OS repair/reinstall will stop the problem.

0x124 is some kind of hardware fault. Since your display turns pink try clleaning out the GPU card in case it is overheating.

Install Service Pack 1 also and check for a BIOS update, yours is from 2009 but may be the latest.

Some hardware tests to run.

Graphics card test:
Video Card Stress Test with Furmark ​

Hard drive(s)test(s):

Pick one for your HDD brand or use Seatools.
7 Free Hard Drive Testing Software Tools​

RAM (memory) test:

This will require memtest on a bootable CD or USB stick.
RAM - Test with Memtest86+​
