Every time my PC tries to install an update via Windows Update it turns off then turns back on again. This happens with EVERY update, either on automatic or manual install. Its got to the point that I have to 'Hide' the updates just to stop my PC knocking off. Please...any suggestions?
Do you have Service Pack 1 for Win 7 on your PC? If not it may be one of the updates trying to install and it has been known to crash Windows see here but as wee eddie says the trouble may be deeper and a virus/malware check is a good idea.
...also I might add, I've just found out that the PC crashes if I try to access 'System Protection' in System & Security/ Control panel.
I've also just done a cleanboot and disabled all the none windows stuff but the problem is still there, was going to start disabling all the windows processes one at a time but not sure how safe this is.
