Please help me, before I throw my PC

SkatDarkstar

Ok so here's the deal, about 3 days ago, I was playing WoW and having a good time, that night, I went to bed with nothing wrong with my computer. The next day I wake up and turn my computer on, it powers on fine, I turn on my monitor, and it says "no signal." I get confused, and my monitor goes into standby. A friend and I built my computer, less than a year ago, and I've never had a problem with it, and then all the sudden my computer goes apeshit. So the basics are this: I turn on my computer, I can hear my hard drive loading, but I dont hear a Windows noise, and my monitor says no signal. I already bought a new power supply, a 600 watt one, and hooked it up, to no avail.

My specs:
eVGA geforce 6600 agp card
asrock 775 Dualpro motherboard
Intel celeron D 64 bit processor
1 gig of corsair select DDR ram
60 gig western digital ATA HDD
250 gig western digital SATA

any other information I probably forgot I'll be happy to include

Assuming you already check to see if your monitor is actually plugged in, does it give you any warning beeps when it turns on? It's probably your video card though.

Forgive me for checking, but is the monitor plugged in?

It's just that I had this the other month and it wasn't and I spent an hour figuring it out.

edit: hah, beat'd

Another thing you could do would be clean the gold pluggy-inny bits on your card with an eraser.

Oh I did forget to mention that, I've tried both the DVI and VGA ports on my card, I'll try cleaning it out as well. If its my card though, I've been thinking about getting a new one anyways, so I guess I have to now

I've had this happen to me just a couple months ago, turned out it was a faulty network card of all things.

Try the card in another computer before you replace it.

Troubleshooting 101:

Pull out everything but the bare essentials to make the machine boot, hell, even your video card if you need to. Go by sound, use one stick of RAM if possible. If that doesn't work and you have another stick, put that in, take the other out and try to boot. Your goal is to find out what is broken. If your machine boots, start adding things back in one-by-one until it stops booting again. If it doesn't boot at all no matter what, then you'll need to regroup and try some new stuff that you might not have the resources to do. But try basic troubleshooting first.

Same thing happened to my friend's computer, and then to my computer.

Turns out it was the RAM in both cases.

So boot your computer with only 1 stick of RAM first, then try the other stick.

Its not beeping right?

Which means that the machine isnt booting.

What usualy happens with that something imporant isnt seated right.

Check all the connections, especialy the video card.

Could be pretty much anything unfortunately, from a cable not fully inserted to faulty hardware. I had the very same symptoms a year ago, turned out to be a faulty motherboard.

I'd suggest you remove as many devices as possible and then boot, just be careful as especially the RAM is very easily damaged.
