my computer has been shutting down at random and once it has started is unable to successfully boot up after, it is possible to access the desktop for a limited time and i have managed to run defragmenter but if it shuts down it cannot start up properly again until it has been switched off
when my computer randomly restarted it was as Storik says the cpu overheating. I got a hoover and hoovered up the dust that had caught up beneath the cpu fan and between the heatsink. Used to run at about 69 or 70 when it restarts but now it doesnt go above 46.
