Hiya,

Recently I've been having a problem with my computer. It happened ages ago just once, but has been happening with more frequency.

Basically I can hear the fan speeds in the computer increasing, then they reach a pitch and the computer black screens. It's still on, but the fan speeds go down and the screen goes black. I cant alt tab or anything. If I leave it on, it will try to restart and it's like a car engine revving. Basically, it starts, kicks out, starts again, kicks out again etc.

Comp specs:

Win 7 64 Bit
Intel Quad core 6600 x 4 [2.4ghz]
ATI Radeon 5750

Thanks =)
 
Solution
Fans speeding up suggests an overheating problem .

Try cleaning all the dust out of the case, cpu cooler and fans
USE A CAN OF COMPRESSED AIR . NOT A VACUUM CLEANER , AND NOT A BRUSH
