Hi, I just assembled a PC. All components are brand new and out of the box. Specs are: Motherboard: Asrock P43Twins1600 CPU: Intel CoreDuo E5200 Graphics adapter: Radeon HD4670 (manufactured by PALIT) RAM: 2 X 2 GB DDR-II Ram (manufactured by ADATA) HDD: 305 GB Hitachy HD System Power Supply: CODEGEN 450W I assembled everything, hit the Startup button and now the only thing that seems to work is the CPU fan. Everything else is dead. My CD drive used to not even open its tray. Then I disconnected it from the IDE slot and now it is like the second working thing on my machine (after the CPU fan). The hard drive is connected to a SATA-I port (also tried connecting it to a SATA-II with no result). It has an old Windows XP installed on it, but I doubt it that this is making all the components in the machine not to work. The graphics card is pretty much dead. It doesn't spin its fan and doesn't send any signal to my monitor (monitor reports "No video input"). I am not an experienced PC assembler, that's for sure, but still, I think there is something that even an expert could not understand here. What could possibly be wrong? This problem is a huge damn mystery and a big PITA for me. Jumpers? This is maybe the last thing I haven't tried messing with yet. Your help is HIGHLY appreciated, folks. Please, advise. Thanks. _

If the CD tray won't even operat unless you disconnect the ribbon cable then something IS wrong. You MAY have the motherboard shorting out to the case. You should always bench test a motherboard outside the case with ONLY the minimal hardware connected. The first thing I see is a crappy undersized power supply.

"The first thing I see is a crappy undersized power supply" Exactly. Would this be the same one for $16.50? http://www.geeks.com/details.asp?in... Why would you spend all that money on the rest of your components but only spend $16.50 on THE single most important piece of hadware in the PC? Other than that, you should ALWAYS benchtest your hardware before installing it in the case. See response #9 in this thread: http://www.computing.net/answers/ha...

All fixed. It was a mistake on my side (just as expected).

And what was the mistake?
