Alas my aged computer rig has suffered BSOD, but I am finding it difficult to diagnose the problem, as I was AFK at the time.

I suspect that my CPU might have overheated as I discovered that one of the case fans had died after I opened the case to look inside. I removed the CPU, replaced the thermal paste and it worked for a while but now it won't restart at all.

I am not getting the POST screen, and I am not getting any warning beeps from motherboard. However, all the other components seem to be working: GPU, CPU fan so the motherboard seems to be working.

Is there any way to diagnose the problem? I suspect the CPU is the problem, so I have ordered a new one. However, I am concerned that if the new CPU is installed, and it still does not POST with no beeps, then I will have no idea which component of my rig might be defective.

Thinking the unthinkable: if my rig (which is getting on a bit) can't be revived, is possible to upgrade my motherboard/CPU /RAM and install the latest version of Windows? If so, are there any recommendations? The only advanced feature I seek from my PC is that it can play a PC based game on high resolution settings.

Only you know your case.  I wouldn't expect a failed case fan to cause a motherboard to fail.

Does your case have good static pressure and airflow?

What was the BSOD error?

Lots of things you can test

Short ground on PSU, test load if you have one of these testers.

Reseat CPU, remove all but one stick of RAM
Remove GPU (if processor has on board APU)
Perform CLR_CMOS using jumper

We can only speculate on what happened.  4 revs of this board, approx. 10 yrs old.  I would have recommended against investing any money into it.  Risky at this point.  Hope it works out for you.
