I'm having the same problem the monitor was saying "no signal to monitor" so I got this plastic cover from my sisters motherboard and placed it on top of the CPU (it had holes n it it and the motherboard I had didn't have one) then it worked! Untilit booted and it said a CMOS error and turned off. I got annoyed and changed the psu voltage and boom! There goes the psu so now I've got a new psu and it still "no signal to monitor" what might be my problem? Thanks in advanced, Adam.
