So I just built my HTPC
5000+ BE
8600GT silent
M2A-VM (onboard video)

So I booted her up for her maiden voyage and I get no video signal from either the 8600gt or the onboard, so I took out the 8600gt and just tried to use the onboard. Still no video

The motherboard light is green, the fans are all on, but there is no tell tale sign for me about what the problem could be.

The computer isnt showing any video signal, actually the monitor does not recognize any video signal, it just says no signal found.

Any help?

Thanks,
Michael
 
try clearing CMOS.. make sure that all additional power cables are plugged.. try booting with minimal configuration - CPU, one stick of RAM and onboard graphic.. also make sure that the mobo supports your CPU (I myself don't have time to do a research for you..).
 
I'd reseat the CPU.

If you have both the 20/24 pin main ATX connector plugged in, AND the 4-Pin ATX12V P4 CPU connector plugged in, then the board should boot fine.

You could test the PSU. Jump start it (on the main atx connector, short the green wire with any black wire, using a paperclip), and see if it stays on. If not, then its probably a faulty PSU. If it works then proceed (though, in rare cases, it may still be the PSU at fault).

Setup everything outside of the case, with the mobo on top of its cardboard box. Plug in only the essentials:
- PSU (namely: main 20/24-pin ATX connector and 4-pin ATX12V P4 CPU Connector)
- CPU w/ HSF
- Single stick of ram
- Videocard if there is no onboard video
- Monitor
- Keyboard
- System speaker/buzzer

* Use a screwdriver if your board doesnt have an onboard power switch. Jump the two power switch leads to turn the power on.

If it won't POST, try different RAM slots. If it still won't POST, pull out the ram (so no ram in the system) and listen for error beeps. If none, pull the vidcard and listen for error beeps. If none, re-seat the CPU/HSF and try again. Report back with results if you're still having issues.

I reseated everything, and took one stick of ram out, no boot.

Put the other stick in, it booted.

I took the known "working" stick and tried it in all 4 memory banks.

Booted to bios.

Took the known "bad" stick and tried it in all 4 banks, no boot.

Obviously the 2gb configuration didn't work either. Im going to install OS and get everything set up this weekend using 1gb of ram.(maybe Ill steal my mushkin out of my gaming computer) and RMA the ram on Monday.

Yay?

Thanks guys,
Michael

PS while screwing around I broke my Sata connect off my OS drive, I super glued it on. Rofl

Good thing its only a 160gb seagate from ancient times
 
Sorry to bump an old thread but I'm having a similar issue.

I recently built a similar system

asus p5n32
intel 6750
evga 8800 gt
2x 1gb corsair dominator 8500

and it worked great from the instant I built it until this morning. As recently as last night I was enjoying gaming on it but this morning the fans spun for ~30 seconds and it powered down. I checked all my connections, reseated the cpu/ram/video card, cleared the cmos, left the battery out a few hours, tried my other pci-e slot, other ram slots...literally everything I (or google) could think of.

Eventually I worked my way down to just the psu and cpu connected to the motherboard and I wasn't even getting beeps about memory or video card. Even with this bare bones setup it was powering down after a few second to minutes.

After lots of searching I think its the motherboard since others have had similar issues. If not I guess I'll RMA the cpu and psu as well though I doubt thats the issue. Anyone have any ideas as to why my pc would randomly not even post after working so flawlessly?
 
If you see power running on the mobo, but, no video signal after swapping video cards, clearing CMOS settings etc. try swapping power supplies. I had an issue before where I turned on the PC and everything powered on normally. The fans spins, harddrive comes on but, no video displayed. I was reseating cables, swapping video card etc but, still the same. I figured that it cannot be the PS as I just bought that Antec Smartpower 2 weeks ago and it ran fine during the 2 weeks. I decided to just swap the PS for the heck of it. Sure enough it posted on the LCD screen.
 
Unfortunately I don't have a backup PSU to test that has adequate power for this system. I bought a brand new Thermaltake 750 watt psu on a friends recommendation.

I read on a different forum that I can test the psu by jumping the green to black cables with a paper clip and let it run to see if it works and it stayed running for 10 minutes like that before I removed the clip. I don't have a voltmeter to test voltages so I can't be sure though.

For some reason I doubt its the PSU...probably because of all the horror stories I've read about P5N32's dying for no reason or just being DOA. If my RMA'd mobo doesn't do the trick I'm going to RMA the psu and cpu as well.
