I recently changed the thermal paste in my PC, but now it won't power on at all. I've done a lot of troubleshooting—cleaned the CPU socket, reset the CMOS battery, and reseated all the power cables and RAM. Still, nothing happens. I don't even get any error messages; the machine just won't turn on. Has anyone experienced this before or know how to fix it?

When you were changing the thermal paste, did you accidentally touch any other components? That can sometimes lead to static damage or disconnections you can't see. If you've tried everything else, it might be worth checking connections again or trying a different PSU if you have one.
Did you remember to flip the switch on the power supply? Sometimes that simple thing can be overlooked, and it’s an easy fix if that’s the case!
Do any of the fans spin or lights flash for even a moment when you try to power it on? If there’s absolutely nothing, it could be a deeper hardware issue.
Is your system showing any signs of power at all? Unfortunately, whenever you take apart a PC, something could potentially fail. I've seen power supplies and motherboards go bad just from repasting a cooler. If you’re sure everything is reconnected correctly, you might need to start swapping parts to pinpoint what’s malfunctioning.
It's not showing any signs of power at all.
