I bought an ASRock DDR 3 1600MHz AM3 motherboard, Athlon II X3, 2 gigs of ram and an HD 4670 Radeon card.
I hooked everything together and the darn computer won't start; here's what happens:
-All fans blow and lights light up
-Monitor doesn't even get a signal from the video card; video card fan and LED light is active
-Hard drive doesn't even function(I know it works because I tried it on my other computer)
-DVD has no power (I know it works)
-USB works; photo card reader has power
-PSU wires are still good. I reconnected them to fans and they are sending electricity.
I do have one speculation: I have an old 350 Watt PSU and I'm thinking it failed to power everything.
Other than that, I'm totally lost. I hope It's not DOA; it's such a hassle to request, get RMA, send with own money, wait, wait some more, then get it again.
