On the surface it sounds like no RAM is on the board.
My friend just gave me a few computers that were having problems, and wanted me to make one out of them. I decided to use the newest mobo, the Gigabyte GA7KML (AMIBIOS) and realised is wouldnt boot. No fans, nothing. I changed the PSU, and was happy to see the fans going (They were going full speed, no slowing down.), but my satisfaction was short. I quickly realised that no video was coming out through the vga port. Not only that, but three short beeps would come out ONLY when I plugged in the monitor. I decided to install a graphic card, to try to get an image appear on the monitor. Still, no video (But the beeping stopped). I have tried three graphic cards but to no avail. I tried swapping the ram with many other ram modules, still nothing. There are few things I have yet to try.
1.)Resetting the CMOS.
This one I'm not too sure how to do, but I'm sure the manual would tell me how.
2.)Disabling onboard graphics.
I looked in the manual and from what I know theres a way to do that by going into the bios, which I cant do. Infact I believe the mobo wont post at all.
3.)Swapping the PSU.
I doubt its this, but it could be.
4.)Letting it run for about an hour, maybe letting it post
I read somewhere that sometimes a computer takes ages to post, you just need to give it some time.
If I could get some help that'd be great.
