Ubuntu Multimedia :: Display Would Sometimes Go Black For A Few Seconds

I installed Ubuntu on a Toshiba Satellite about a month ago. It worked for about three hours. I installed Wine, and it still worked but the display would sometimes go black for a few seconds. Later that day I rebooted and that was it, no more Ubuntu. It goes through all of the process of booting but then the screen just goes black before I even get to the purple Ubuntu screen. I'm running this on a drive in an enclosure so I simply plugged the drive into another machine ( actually two other machines ), and it works perfectly. I have an old Vista drive that I put in the Toshiba and that works just fine, so it's not a pure hardware issue. Just to be sure I wiped the Ubuntu drive and re-installed, this time without installing wine. No Toshiba love. Just the black screen. I even made a flash drive with the loader and iso from the Ubuntu site. Same deal. It starts to boot from the flash and then just goes black where you would normally expect the purple Ubuntu screen. This thing is driving me nuts and I am at a point where I really need this machine working and will be faced with simply wiping the Ubuntu drive and installing Windows.
