My mate has one of these and he has ran into a few problems... His system seems to run for a while then just throws a BCOD up......I had a quick look, i'm no expert but i've built my own PC's so I have a grasp of what does what. Now, the fan on his heatsink isnt spinning so I thought that it could be an overheating problem. We got a new fan......actually he did, wrong size and all of that but did manage to screw an 8cm fan onto a 7 cm heatsink (yep.....words fail me too)........now when he connect the cable to the motherboard it doesnt always set the fan away spinning. Is there a BIOS setting that controls the fan? Could he have switched something off. I think the motherboard is an E22m 91TF88OU334, but I heard that Acer get stuff from Foxxcom. Any help would be deffinitey appreciated. DB :)
