A sudden shutdown after a restart

by Matriixx / July 16, 2013 12:21 AM PDT

Heyy there.

well, I've been looking everywhere over the internet to check if someone got the same..

couple of months ago, i decided open up my computer and clean the parts, after i was done with it, and put the parts back, everything worked fine, after days, my pc froze up suddenly, so i had to reboot it manually which is by pressing the reboot button which is in my computer. therefore, it turned on normally, when my computer went into automatic repair mode, it shuts down, i tried many several times and it keeps on shutting down, i had to leave it for a while, after hours i decided to turn it back on and it worked normally, i thought the problem might be form the power supply, it was so old and t was doing some noises..
so today i went to a computer shop and took my PC with and told him to change my power supply. the one i had was 450W so i told him to replace it with a 550W i thought it might be a good one, before half an hour i came back home, i was like i should format my computer, but also, when i tried going to the boot up screen and choose the bootable USB drive, it turned off once again, i wanna know whats the problem.. & i hope i could find it here :/

I'll leave you guys with my computer information

That CPU's heatsink

Is well known to pop off as well as the heat sink compound to crack and fail. I'd pull that and do the usual work and hope for the best. If not, the machine does look dated. It may need a new motherboard or other parts.

Usual work.

Remove the heat sink and fan unit, remove the lint from the heat sink under the fan, clean that up then wipe off the old compound (does not have to remove every single molecule) apply fresh, re-attach heatsink and be sure it's on solid then power up and be sure the fan is spinning then try again.

At near 100C, that's far too hot.
