After spending quite a bit of time on Newegg, I put together some parts for a computer that I'm building for a friend. The parts finally came in, I spent about an hour building the machine and decided to give it a try.
When I cut the machine on, all the lights work, the fans work but no video output to the monitor. My immediate thought was that the video card that I installed was causing the issue, so eventually after try with no luck I unplugged the video card (Nvidia GeForce 9800 512mb PCI Express x16 2.0).
After removing the card from the machine completely, I plugged the monitor to the on-board video (attempting both DVI and VGA ports); still no luck.
I then went through to make sure everything on my list was compatible and as far as I can tell, they all are. The mobo, cpu, and ram are listed below; the only other parts are sata hdd and dvd rw.
Here's what I got:
ASUS M4A78LT-M LE AM3 AMD 780L Micro ATX AMD Motherboard
AMD Phenom II X2 550 Callisto 3.1GHz 2 x 512KB L2 Cache 6MB L3 Cache Socket AM3 80W Dual-Core Desktop Processor
G.SKILL Ripjaws Series 4GB 240-Pin DDR3 SDRAM DDR3 1066 (PC3 8500) Desktop Memory Model F3-8500CL7S-4GBRL
From what I've told you and the specs above, can anyone come up with anything? I'm almost pointing towards a defect in hardware.
