Question about PC Desktops

1 Answer

Power of Recently my ASUS A7T NOTEBOOK which had been running for about 5 hours suddenly shut down. I rebooted and it ran OK for a few hours and did the same again. After a dozen more reboots all it does when the front power button is pressed is power-up for 1 second max then shut down. The light at the front comes on (and stays on after shut down!) and the chip and case fans run for that second. If I try to reboot nothing happens unless I switch the power supply switch from on to off and back again. Then it reboots for a second again when I press the power button. I haven't made any hardware or driver changes recently so was wondering if anyone had any suggestions. Could the power supply be faulty or something tripping it out?

Re: power of

This happens because your CPU is overheating, open your PC and blow any dust off the openings and CPU/Power supply fans, if you think one of the fans is not working... replace it.

Asus m32 rebooting randomly

Check to see if your PC is over heating which would normally cause the fan speed to increase. Overheating will cause it to shut down unexpectedly. Cleaning all the dust from the power supply and vents will prevent overheating. Make sure the fan IS running.
After you back up your data, run disk diagnostics on the hard drive to fix any bad sectors.

Why does my computer suddenly shut down during use?

remove the side panel and have a look if your cpu fan is turning.... you may need to blow the dust and dirt out of it as well... if the tower even feels remotely warm that's likely the issue... also check the fan on the power supply. either way it will likely need to be cleaned
