Basically have this office computer here. Windows 8, was working fine till one day its suddenly extremely slow, barely boots, BSOD'ing randomly (bad_pool_header on the last bsod). However, works completely fine in safe mode.

Note: not exactly my computer, so I don't know what changed "one day"

Normally, I can't even pull up task manager at least to start somewhere.

What shall I do guys, to begin basic general diagnostics?

All help is insanely appreciated, and thanks in advance for all those who help. (Sorry if I'm posting in the wrong category ;-; it's been a long while since I've came on here)

Should get IT section to look at it unless that is you.

If you still having the problems, there are two things to try to fix that last error

1. Try running driver verifer, just read the instructions carefully. It is part of win 10 designed to find misbehaving drivers. It will cause BSOD, that is its job since it tests drivers.
note: sometimes this will put you into a boot loop so it helps to have a win 8 installer handy to get out again. Also helps to run system restore before hand to create a backup to roll back to if necessary.

Once it bsod, run Who crashed and see what driver it reveals

The instructions to stop it looping are in the link above I will show u anyway
change boot order so USB is first, hdd second...

boot from installer
on screen after languages, choose repair this pc, not install.
choose start up options
hit the restart button
choose a safe mode (it doesn't matter which) by using number associated with it.
Pc will restart and load safe mode
Now open command Prompt
type verifer /reset and press enter
restart PC

2. run memtest86 on the ram, 1 stick at a time. Any errors are too many and stick needs to be removed/replaced. It makes a bootable USB so don't need windows to run it.

running who crashed will reveal all BSOD so might help to copy/paste the summary here.
