Hi... My PC keep restarting in every 5 - 10 minutes. I tried to troubleshoot everything including disabling "auto restrat" option and formatting my PC and doing clean install. Still the problem is there. Then I suspected power fluctuation issue. So I tried to connect my whole PC system in my neighbor's house and same problem happened. Later I connected my PC at my uncle's house in another area and it doesn't restart. So temporarily I came to conclusion that it is may be because of power fluctuations in my area. The issue just started since last 2 months. Complained to electricity officials but you know how these organizations work in India. Below are my PC configuration. OS: Windows 7 Ultimate Intel i7 6700k Asus Z170 Maximus VIII Ranger 32 GB G-skill Ripjaws (8GBx4) 240 GB Kingston SSD 4 TB WD HDD (1TB x 4) 4 GB Asus GTX 960 DDR 5 Graphics Card Heatsink liquid Seidon 120m LG DVD Writer 600W Cooler Master SMPS 22" Dell S2216H LED (2 Monitors) Creative SBS A-355 2.1 Speaker Wacom Pen Tablet APC BR 1100CJ-IN UPS Keyboard Mouse My UPS is in great condition and in power failures, give 20 minutes of backup. But it can't prevent restart. Also I keep all my drivers up to date. The total power consumption of my PC comes around 1200W I guess. Do you think I need a voltage stabilizer? If Yes, then which is best? My budget is around 8K INR.
