Dell Dim. 2400 mobo

Hello to all,
I am new to this site.Hope to learn a lot from the best.
I just dismantled my pc to assemble it back again(first time at it). I also removed the cpu chip and noticed some of the pins were bent. Yes I know not to touch them but I could bot resist to fix. I straightened them out. Put it back into place. I put everything back as it was. Turn it on,the fan spins, I see power running to the cd-drive and hear the hdd working.
My keyboard and monitor seam not to be getting any signal at all. I plugged the keyboard to other pc and it worked.

Could I now have a bad mobo even though i hear working harware?

Yes I did use a ESD mat & wrist strap

The Dell 2400 is a stable motherboard, however it has had heat sink and cpu fan problems from time to time. I would pull your CPU and double check those pins... then assure that you have the CPU against the heat sink with some good heat transfer paste, and that the fan is working properly.
Another problem we have found is common with that model is that the plastic rack for the heatsink and fan tie-downs or clamps, breaks or cracks so that the heat sink is not held firmly against the cpu.
