So I'm building a desktop computer. Here are the parts I used:
Motherboard: Intel BOXDP67BGB3 Socket 1155, Intel P67, CrossFireX & SLI, SATA3&USB3.0, A&GbE, ATX Motherboard
Processor: Intel Core i5-3470 Quad-Core Processor 3.2 GHz 4 Core LGA 1155 - BX80637I53470
Power Supply: Rosewill Stallion Series 500W Power Supply RD500-2DB Black
Video Card: EVGA 512-P3-1300-LR GeForce 8400 GS 512 MB DDR3 PCI Express 2.0 DVI/HDMI/VGA Graphics Card
Memory: 2 of Crucial 4GB Kit (2GBx2) DDR3 1333 MT/s (PC3-10600) CL9 Unbuffered UDIMM 240-Pin Desktop Memory Modules CT2CP25664BA1339 (I got 4 of these chips to total 8 gigs)
Computer Case: Rosewill Black Gaming ATX Mid Tower Computer Case CHALLENGER
When I put all the parts together I made sure to use an anti-static wrist-band so as nothing would get destroyed, I made sure that it was in a dust-free environment, and I made sure that I put all the parts in properly. I have checked all the wired connections on the motherboard and on the hard-drives.
Now my problem is that it will turn on and all the lights on the motherboard will turn on, but I see nothing on my monitor. I know that the problem isn't the monitor because it works when I connect it to my laptop or any other computer. The fans will start going and it will seem like its booting up but then the power just cuts out.
On the actual motherboard there is a little clock-like thing that displays the number 26 and sometimes 31.
I was hoping that someone could tell me whats wrong with it based on the information I gave, but if you need any more information about it then please ask.
