Help: upgrade gone awry

[drinferno]

So I recently replaced my heatsink and fan. After assembly, the pc powers on, and starts to boot. It gives a CMOS checksum error, and then powers off.

I did some stupid things due to curiosity. I took the chip out when i cleaned the old thermal paste off. I dropped my pliers on the motherboard when i was removing the old heatsink.

So i'm trying to diagnose the problem and figure out if there's something i can do to salvage the parts.

motherboard: 780 SLi
chipset: intel e8400

thanks for the help!

Unplug the PSU and take the battery out of the board for 30 seconds, this will reset your CMOS.

I removed the CMOS battery as suggested.

I reinstalled the heatsink and i probably used too much thermal paste. I cleaned the chip of all the excess thermal paste, carefully this time.

The computer will boot to the point where it tries to boot from CD.
then it powers off.

I'm puzzled because i'm a fat, greasy noob

What OS do you have?

 

[fimbles]

Can you boot in to bios? ( press del or f2 after a restart) Does it still shut down if left in bios for a while?

If you can, restore optimal defaults, save and exit.

I would also try removing the cmos battery for a longer period of time, 20 to 30 mins. Or clear the cmos with the mobo jumper.
