Recently, my computer just stopped turning on.

Basically, when I power it on, all the fans and everything start up like normal, but the screen stays black and gives me a "no input" error. I'm guessing that means it's a video card error, but about two weeks before it stopped working, when I restarted my computer (I leave it on 24/7) I got some sort of BIOS error, where it said it was repairing the BIOS, then it would restart itself and it did that about 15 times before it started up normally.

I didn't really pay any mind to it, but now that my rig won't even start up, I'm not sure what to do. Almost none of my friends use desktops anymore, and the ones who do have real old rigs with AGP cards so I can't test em out on my mobo. Any other ideas for what I could do to diagnose the problem? I've only had the rig for about 2.5 years. Running a 7900GT on a GIGABYTE GA-965P-DS3 socket 775.


Any ideas?

Yes. I've done the barebone test, nothing. I've pulled out the RAM, vid card, and reseated the CPU/HSF and hear no beeps, still nothing. I replaced the mobo battery, still nothing,


I'm guessing this means it's the video card? Everything else seems to be working as it should.

EDIT: Tried another monitor, does't work either, so it's not my monitor.
 
Should probably say that it's not necessarily an error, my monitor just tells me that it basically is not detecting an input device.
 
is by any chance your keyboard not plugged in?

I had a similar issue once and i spent an hour taking everything out testing, putting it back in only to realize that i hadn't plugged dint he keyboard............

I'll try plugging it in again, but the problem started when it was already plugged in. I'll try it out though.
 
Got a new motherboard, still not working. This is frustrating the hell out of me.
 
Do you have an old PCI graphics card laying around anywhere? Looks like you have tried about everything but the most logical thing. Try a different video card. ;)

Yeah I guess I'm going to have to. I took it into this shop that fixed my laptop a while ago and they said the videocard was fine and the motherboard was the problem, but I guess it was the other way around.
 
Try a PS2 keyboard, as some motherboards will halt if they don't detect the keyboard, and if your CMOS cleared itself it might have problems detecting that via USB.

Otherwise I'd guess video card, or possibly your CPU.
 
I have this same problem, but with a new build. I've tried replacing the video card, cpu, and memory but I still get the 'no input' window on the monitor. The monitor works just fine too on my old computer, it's just very odd.
