Ive posted a graphics card problem on another forum category here, but I haven't given it a try in the Windows one. What my problem is basically my computer would crash, and then when the computer would restart, there would be green blocks in the BIOS and then when windows vista would start to load there would be green wavy lines going down the whole screen. There would be also white dotted lines going down the screen too.

When this was present at startup, windows will not load to desktop, and I'd have to use my computer in safe mode with networking, as I am right now actually. This problem would go away randomly, without me altering any settings or files on the computer.

Can anyone explain all of these green blocks, wavy lines, and dotted lines at startup? Is it a windows problem at all?

From least time intensive to most:

1. Reinstall drivers
2. Clean all fans, esp. graphics card
3. Replace graphics card/power supply

I have tried almost everything on drivers I could possibly think of. Uninstalled them completely used the most updated driver, that didn't work so i rolled back a driver or two, that didn't work, used the driver that came on disc for the graphics card, that didn't work either.

I have already tried cleaning out every fan in the computer including power supply and graphics card.

Its not by any chance a CRT monitor?
(Cathode Ray Tube)

Its a lot more common on them, and quite often just a dodgy connection, try pushing the cable in better, or taking it out giving it a blow and putting it back in.
