A friend has just dropped his pc round saying it wont boot up. We have checked his monitor, g/card and ram and these are all fine. When you turn it on all the fans start up (although they seem to be running very quick) but it won't boot and the optical drives won't eject, however if you take the ide cable out of the back of them they work/eject fine. Its an Advent 3.4 pentium on a msi mobo with a 450w jeantech psu. Any ideas/help gratefully recieved.
