Building new computer, monitor not recognized

Sevyrd · 07-19-2008, 09:18 AM

Hello all. I just recently built myself a new computer, I have built computers before so I'm fairly 100% that I did everything correctly. I am having some problems with it though so I was hoping maybe you all can be of assistance.

As I said, I am almost 100% positive that everything is hooked up right. The motherboard is an ASUS M2N-SLI Deluxe. The motherboard however did not come with integrated graphics. When I turn on my computer, it turns on fine and stays on, however my monitor isn't being recognized with the video card. I tried installing three different video cards with it, a nVidia GeForce 6800 and 8800, which are both PCI-Express, and another card which I can't remember off hand but it is just normal PCI, and none of them work, the monitor just stays black. Does anyone have any idea what it could possibly be? Any help would be greatly appreciated!

Also I'm not sure if this matters, but I'm using two Corsair DDR2 800 2GB sticks.

If you remove the RAM does the motherboard Beep?
What CPU are you using?
What PSU?

No, the motherboard does not beep if I take out the RAM.

My CPU is an AMD Athlon 64 X2 6000+. And my PSU is a OCZ GameXStream 700W

Try following the steps in this thread all you want to with this method is get the board to post to the Bios screen, Post back with your results.
How to Bench Test Your System

OK. I just tried doing this, and now when I hit the power button the fans and everything spin for maybe a second and then the system shuts off.

wrench97 · 07-19-2008, 01:59 PM

But the fans stayed on before?

Sevyrd · 07-19-2008, 02:07 PM

Yes, that's correct

wrench97 · 07-19-2008, 02:10 PM

Try to reset the cmos and double check all your connections as well as the cpu mounting.

Sevyrd · 07-19-2008, 02:26 PM

Checked everything, everything seems fine, put more thermal past on the CPU, and I reset the CMOS

wrench97 · 07-19-2008, 02:38 PM

IF you remove the memory does it beep now?

Sevyrd · 07-19-2008, 02:40 PM

Sorry I should have specified. The connections were fine and everything yet it still powers down after a second.

Sevyrd · 07-20-2008, 04:56 AM

Is it possible that I have a bad motherboard?

wrench97 · 07-20-2008, 05:12 AM

Yes it is normally if you get no beeps with the memory out it's either the back of the board shorted to the case or a misplaced stand off (you eliminated by doing the bench test), a bad board, a CPU not supported(yours is) or extremely rare case a bad CPU.
I would think a bad board is your case.

Sevyrd · 07-20-2008, 05:46 AM

Yeah that's what I thought too. OK, thank you for your help, I will send back my bad motherboard. If I have any questions once I get my new board in I will post back.

Thanks again!
