Make, model, age. If new let the maker fix it.
My computer is restarting randomly ,frequency of restart is random (varying from a few hours to a day)
Strange thing is that the computer did not restart at some other location.The only difference was the power cable (which i already replaced) and the power supply from Mains AC power at that location. (New APC 600VA UPS already installed at my location giving backup and switching instantly to Battery mode in case of power cut.) Moreover, Inverter of 800 VA is also installed with inbuilt UPS feature ON.
I have already checked the current PSU in different location ,it's working fine. I tried to run the computer on different power point / wall jack but after around 20 hrs it restarted again.
Now, I have disconnected the hard drives and running the machine in BIOS only. I still need a day or two to check the recurrence. It has been very frustrating and annoying and also 1 of my hard drives have got bad sectors and delays due these restarts.
Kindly suggest possible cause and fix.
