Pc keeps restarting after the bios screen

[1907sk]

Hello everybody!

I have a problem with my pc here, hope you guys can help me out.

Yesterday, I have changed my standard cooler for an after market cooler. My pc keeps rebooting now after the bios screen.
These are the things I already have tried:
- I have resetted the cmos.
- I have also tried to start the pc with only 1 ram and the cpu. It was still rebooting after the bios screen.
- I have also pulled all of the cables out of the motherboard and put them in again.

Before that, I dropped my cpu by accident, while trying to clean the remaining thermal paste on the cpu. I don't know if that is the case of my problem? The cpu itself looks like it is fine.

My specs:
os: windows 7 ultimate 32bits
motherboard: sus p5qpl-am
Psu: stock psu 300 watt
cpu: intel celeron e3300, 2.5 ghz
Cpu cooler: cooler master hyper 212 plus
Ram: 2x, Buffalo 1gb, pc2-6400

Thank you.

And sorry for my bad english

What type of surface (carpet, tile, wood, etc) did the cpu drop on and how far was the drop?

Also, when you reinstalled the cpu, did it drop right into the socket or did you need to use a little force?

I have dropped it on my wooden floor and the height was I think like 50 cm or so. I had no problems by reinstalling the cpu again in the mobo. Here is a photo of the backside of the cpu: http://tinypic.com/r/w9w7ew/5

Did you plug in the fan on the 212 to the motherboard?

Do you have the small piezo motherboard speaker installed and are you getting any beep codes?

yes, I have connected the 212 fan to the motherboard and it is working properly. The piezo motherboard speaker is installed too and there are no beep codes coming out of the speakers.

When you removed the old heat sink, did it come off easily or did it pull the cpu out of the socket?

I have also tried to boot from a windows dvd. At first I have connected the DVD drive to the PC I have also changed the boot priority number one to CD ROM. When starting the system, this shows up after the bios screen: 'Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key.'

The interesting thing is that when I put the hard drive on priority 1, it shows the same message on the screen. I have also tried to start it, without the hard drive was connected and that it showed the same message again.

The old cooler did came off pretty easy exactly. I had no problems at all by removing it.
