Hi

I recently put a system together

amd 3700+ s939
evga 7800gt
2gb ocz ddr400 ram
200gb wd ide hd
dvd burner
evga 133-K8-NF43-AX motherboard
520w(i think) psu

So I build the system everything seems fine. I power it on, no beep signifying POST completion or anything. no beeps at all. everything powers up and spins fine.

i get no signal going to the monitor(green light on monitor just stays flashing.)

tried clearing the cmos, nothing happened.

does anyone have any ideas? i cannot for the life of me find out why this system wont post and its aggrivating me.
 
Have you tried unplugging everything but the basics? Like just the cpu, 1 stick of ram, the video card? Checked to make sure all of your plugs are in properly?
 
try an out of case build with just the basics, then add stuff on. If that works you need to make sure you arnt grounding your motherboard.
 
ok so i pulled the board out of the case.

so i have the mobo, cpu in, 1 stick of ram, and video. power on, fans spin up, no beeps, no video.

cleared cmos. power up, same thing.

i'm stumped..i know the cpu is working fine as i tried it in another board and it worked with no problems.

is it safe to assume the problem is either the video or the mobo then?
 
Take out the video card and make sure the speaker is hooked up right. You should get beeps informing you that you have no video. If you still get no beeps, then the problem is most likely narrowed a bit more to exclude the video card.

You said you did try one stick of ram, but, have you tried swapping them if you had more than one to begin with? Just checking since you didn't say. (I was taught to ask "is it plugged up" first when someone says their computer doesn't turn on.) Also, you said you had another board to test the CPU in, so have you tested the memory in that other board? For that matter, tried the video card elsewhere yet?

Your problem most likely is your motherboard, but, the only way to be 100% sure is to narrow it down as much as is possible.
 
I tried the CPU in another motherboard but that motherboard was AGP not PCIE. Yes I have tried swapping the memory between slots, different sticks, etc. It's really hard for me to test the video card elsewhere because I don't know anyone with a PCIE board that isn't out of the way. im getting some hardware i can test with on friday so until then ill just try to test as much as possible.
 
Unplug the power cord from the PSU for a minutie and replug it. seemed to work on mine here at the office. OR Maybe the VC is lose??
