Hello any help out here, Funny one I think. I have a Asrock Mother Board, AMD Processor 6 Core, Solid State hard drive Agility so I am running everything on Sata 3, 8gb Ram, Corsair CX500M Power Supply, Asus Nvidia Geforce GT 610 2GB Just Bought, Acer Monitor.
The PC boots up normally but monitor starts but then no signal, but the funny thing is I have put my CD Rom as bootable device, for backup it is second in the boot menu, when i have no signal on Monitor if I put a CD into the CD Rom the monitor comes on and I can do all my work while CD is In the CD Rom. I thought it might be Graphics Card so I bought a New one, now leaning towards Power supply but I can not keep buying Parts on a Whim. Any Idea's.
