Here is my problem, When I boot up my PC the monitor comes on then goes off. I switched out the monitor thinking that was the problem. It still occurred. I switched out the cable next. Still continued. I was told I needed a new graphics card. I have an onboard graphics card currently. So today I put in a new power supply and a new graphics card and still no monitor so I put it back in the old connection and now it says to check my connections. Help please I can't even see to get the BIOS up. Can this PC be saved or should I just scrap it and get another one. I really don't want to have to replace the motherboard if I don't have to.
