Hey,
Here is my situation, I'm running Vista Home Premium SP1 with Bootcamp on my intel-based iMac. I use Vista on it for playing online games.
Recently while playing the game freezes and closes down, then a tool tip pops up saying there was a driver fault. This happened a few times but it was nothing major. Today i went out for 5 mins came back and the monitor was black, but with the backlight still up so i knew the computer was on. I moved the mouse and typed on the keyboard to see if it was just sleeping but nothing happened so i turned it off at the back.
Now whenever i turn it on it works fine for 30 secs but then freezes and does some wierd graphical glitch. It normally just distorts the screen but i left it on for a while to see what it would do and the mac started flashing loads of diffrent colours.
Too me it sounds like a driver fault or maybe overheating but i fear it could be something worse. If anyone could help me out that would be awesome
.
My iMacs spec is:
3.06 GHz processor
nVidia Geforce GT 130 graphics processor with 512mb of GDDR3 memory
4gb ram
1tb hard drive space.
