Re: Computer restarts when voltage fluctuates
1. Check if the earthing thing is intact, or if it is installed at all !!
2. If (1) is 'no' some thing in the mobo could have gotten messed up.
3. Is the electricity department doing some works around the place?

Are you saying you connected ups to a stabilizer??
If yes, then the time delays of stabilizer & UPS while switching modes, are adding up & hence the chance of restart.
Also, is your home equipped with a inverter/UPS?

Re: Computer restarts when voltage fluctuates
Your PSU and the iBall UPS are horrible products. Get a decent PSU and all your problems will be solved.
A decent PSU can take voltages between ~100V to ~265V so the fluctuation won't be a problem.

Re: Computer restarts when voltage fluctuates
Hey, if you do suspect your PSU to be the fault or find it to be the case, check thoroughly for any physical burns it might have left on the mobo. I lost one of the mobos that way. One of the 4 cpu pins was burnt.

Re: Computer restarts when voltage fluctuates
I think changing the PSU should solve the problem.
Happened often with me when I had a generic PSU. Everytime there was a power cut, the computer would switch off instantly. But when I got Corsair CX400, the problem was solved.

Re: Computer restarts when voltage fluctuates
I had faced the same problem some days ago. Now I am using a UPS and it is working fine.
