Question No signal. Please help me figure out what the issue is here

[Taya]

So it all started with my cpu overheating, cooler is working fine, and I did a dust cleanup recently. So I thought it might need a reapplication of thermal paste, but that wasnt it. Eventually I started getting BSODs, all kinds of BSODs, to name a few:

"driver irql less or not equal"
"SYSTEM THREAD EXCEPTION NOT HANDLED"
"Critical Process Died"
"SYSTEM_SERVICE_EXCEPTION"
"KMODE_EXCEPTION_NOT_HANDLED"
"attempted execute of noexecute memory"
And lots of the generic "pc ran into a problem and needs to restart"

It used to work after a few BSODs, but eventually ran into a BSOD loop, and finally to not getting signal on monitors which is where I am now. All the lights and fans are on but no signal.

I was certain the cpu was faulty, but I tried a spare cpu (that I know for sure works) but to my surprise, that wasnt it.

I also noticed that external hard drives wouldnt show up in file explorer but they do in disk management.

What is the problem here? 🙁

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

"driver irql less or not equal"
"SYSTEM THREAD EXCEPTION NOT HANDLED"
"Critical Process Died"
"SYSTEM_SERVICE_EXCEPTION"
"KMODE_EXCEPTION_NOT_HANDLED"
"attempted execute of noexecute memory"
And lots of the generic "pc ran into a problem and needs to restart"
We would also need to see the .dmp files for us to see what might be triggering the issue.

Ah of course, my bad. I'll include the specs but I cannot get the dmp files since my pc isnt working

In this whole time have you ran the same install of Windows.

The over heating/BSOD could have corrupted Windows files and not dealing with the BSOD's to correct Windows your at the point you at now.

My go to is to put a loaner SSD into PC remove all current SSD's/ hard drives and just with the spare fresh SSD install Windows.

If PC now runs correct it's is your old SSD with the old Windows.

If PC still runs like crud than we jump into hardware.

I also noticed that external hard drives wouldnt show up in file explorer but they do in disk management.

Again sounds like a corrupt/files windows install.
