Subject: Re: is my power supply dieing?
If you are looking at thermal paste, you should check that none of your
motherboard's capacitors have swollen up - they can go out of spec. If they
are new, or little cubes then this won't be a problem. If your motherboard
is older and has cylindrical capacitors, there was a batch that would age
poorly. They swell and the top domes up - good caps from this time have
flat tops. Replacing the dozen or so bad caps can be done if you have mad
soldering skills - a new motherboard might be a better option. This is an
unlikely problem to have with current motherboards, but if you're looking
at the thermal paste, it's a thing to also check.

stay grounded & good luck
