So a few months ago I took my heatsink off, and I noticed that no booting would take place; not even BIOS.
Eventually, after continuous and repetitive power ons and offs, it would occasionally work again.
I then removed the heatsink again, and the CPU from the socket to inspect it, but had trouble putting it back in (there were no indications on how to do so), and I dropped it several times on the pins, bending several of them.
I didn't think it would do serious harm, but over time everything on my OS would suddenly be slower, as if there was some problem getting worse with the microprocessor. I continued....
Now it will not work at all, and hasn't for about a month or so.
I tried desperately to straighten the pins, but can't manage it, as some are so strangely bent they won't retract in place. I tried using toothpaste as a heat dissipator, but nothing ... I removed the RAM and tried to boot to see if BIOS would catch the error, but nothing.
The heatsink still spins, so obviously the power supply and motherboard in general is still working, but the CPU seems to be the problem, and/or the socket.
Any suggestions? I also removed the CMOS battery, placed it back in, etc. Everything, but no success so far....
