The monitor was pluged in 9800 , yes I tried to use onboard video and still nothing. All wires are pluged correctly I'm sure. I was just restartig the PC (not with the button on the rig) . having no idea what happened..

now awaiting for 700psu ,becouse my old one were stoped working, and I put the 400W one.
So you put the CPU in a different motherboard?
Put the video card in a different motherboard?
Put the memory in a different motherboard?
Put the power supply in a different computer?
Tried booting your current system with the hard drive and CD-ROM drive removed?
Have you tried putting a different CPU in the new motherboard?
