Computer has died, need fix now.

Computer has died, and I'm leaving in 3 days and won't be back for 3 weeks. I want the computer running because it has lots of content I can use remotely. It was fine until I opened it up to clean the air filter and dust off with compressed air. I also installed a floppy disk because I need a RAID driver during Windows install and I wanted to format and reinstall it tonight. After  I finished I hooked it up and it booted fine so I shut down to close up the case and all of a sudden it won't get a video signal anymore. I've tried analog and DVI connection, I cleared the CMOS, I disconnected all peripherials except video. I get no beep codes, Num Lock functions normally. I think the video card is dead since but I don't have another card to test. I'm in a dorm and all my spare stuff is at home. Does anyone have any last suggestions?

BTW, i'm posting from my 600mhz Celeron laptop.

Before panicking, try re-seating the video card.  It's not unusual for a card to be accidentally loosened while the case is being closed or while you're plugging it in for the first time after closing the case.

The card has a Zalman ZM80 on it which makes it very heavy so I've been aware that it sometimes won't make great contact which is why I've reseated it several times to no avail.

I took the PC apart and rebuilt it again and finally it worked. I wish there was a way to make better contact with the PCI and AGP slots.
