i am having weird problem with my pc
it keeps rebooting daily at 8 pm to 1 am and works fine the rest of the day
so the problem in the power supply or windows or what
sometimes it reboots before the bios loads and sometimes at the windows logo and sometimes after the windows starts so plz help me
i wanted to add that no viruses and it was working fine till last week
1st thanks for the reply
i suspected that also so i changed the psu but still same problem
i am using cheap psu not famous at all so u wont know it , and plz tell me if there is anything possible to make me sure ?
What's your line voltage and what are the voltages coming out of the PSU when the system is stable and when it reboots by itself? If voltages always are within specs, then something else is causing the issue. A computer can't be unstable only between 8:00 pm and 1:00 am and fine for the other 17 hours. You need to figure out what's different for those 5 hours.
Right-click My Computer, and then click Properties.
Click the Advanced tab.
Under Startup and Recovery, click Settings to open the Startup and Recovery dialog box.
Clear the Automatically restart check box, and click OK the necessary number of times.
Restart your computer for the settings to take effect.
Now when you go to shut down and a fatal error occurs, you'll at least see it and it won't cause an automatic reboot. You still have to sort out what's causing the problem, but that gets us to the next section quite nicely.
