Vista - Computer crash after vista update - help!

I have a gateway MT3422 that I have had for 2 years and it came with vista. I have had to restore my computer once since I have had it and never had any serious problems with it. 3 months ago, my computer was trying to install SP1 and when the computer restarts, it goes to a blue screen, then into a black screen and it says "error, calling phyllat...can not find operating system" and it locks up. I push ALT+CTRL+DEL to reset it and it reboots and says the upgrade did not install and gives me the option to reinstall it. After 3 months of trying, I gave up and ignored my computer to download and install the service pack.

Then one day, it actually installed SP1 and when it restarted, it said "error, do you wish to launch system restore (recommended)" I did and it went to a black screen for 4 hours - no cpu or aything running or eve the blue cpu light to show its running. No fan on, no noise from the processor. I shut my computer off and it doesnt ever go to the windows vista loading screen.

Ive tried to boot in safe mode and it gets hung up on system/windows32.....drv and never goes any further and gets caught in a loop. I pushed f8 to launch the repair mode, and it gets caught in a loop. I put i my restore disc that came with my laptop and when I ask it to install windows vista, it gets caught in a loop. tried to do a system restore and it cant because my C drive is corrupted.

Is there anything I ca do or is my computer toast? I really have no more money for another computer...and I need my computer for school. Any thoughts or ideas are greatly appreciated!
