tryed it again... BOOM shuts down
so i tryd installing 73 windows upgrades took an hour or so it didnt shut down?????
im like ok sweet its fixed

tryed upgradeing videa card drivers and sound and it did it again.... even when i do 1 thing at a time it will shutdown...

ya temp are like 30c and 90c i belive off top of my head my i turned the fail switch to off so why would it shutdown??

at 90C you can almost start cooking.

what ever device has the 90c is you problem why it reboots.

If it is your CPU, you might have to take off the CPU cooler, reapply heat paste, and remount the cooler.

Usually I mount the cooler while the motherboard is outside the case before I install the MOBO.
