No beep, fans running, DVD drive working, no signal on monitor
I have built my first ever PC, but I just can't get it working.
I am pretty sure I've built it correctly, but the only things working atm are the fans + gpu fan and the DVD drive. Not sure about the HDD because I have no way of checking. My hardware is as follows:
PSU: Corsair VX550 CPU: AMD Phenom II 955 GPU: XFX Radeon HD 4890 MOBO: Gigabyte GA-MA790X-UD4P RAM: G-Skill 4GB DDR2-1066 HDD: Western Digital Caviar GP 500GB DVD: Samsung SH-S223F CASE: Cooler Master Storm Scout
When I turn my PC on as I said, there is no beep, no signal on monitor, but the fans are running and the DVD drive works. When I turn it on, I am unable to turn it back off without using the power supply switch (which I'm afraid might damage my parts, but I have no way of checking if I'm fixing the problem with changes without doing that). Does anyone have any idea why this might happen?
I think I might have a faulty motherboard, because when I had it delivered I noticed there were two scratches on the bottom of the board that were very noticeable. I'm afraid this might be the problem, but I'm not quite sure. Are there any suggestions on how to fix this?
