Hey, my PC has been instantly shutting down and turning back on on a daily basis (3-5 times a day) and I don't know why it is doing this. When it shuts down my keyboard, mouse, and headset lose power but my fans are still running, so it's basically completely random restarts. This happens on COMPLETELY random times and sometimes it even crashes, and right when im about to put in my password to get back in windows it does it again. Also, I reinstalled Steam recently because when I would play games it would randomly crash as I'm playing and it kept on doing that when I tried to get back on. But as i'm redownloading my games it is constantly saying (corrupted download) or (corrupted update files) as I'm redownloading like 5-7 times before it finally hits 100%. I think I had this same problem a long time ago and it was due to corrupted RAM / Motherboard so it might be the same problem repeating itself. I'm just looking for answers right now so if anyone might have a clue to why this is happened please answer! Thank you!!

EDIT: My motherboard and RAM cards are from a prebuilt PC that i transferred to my current computer. (Alienware x51 r2). And my crashing is not due to overheating, my GPU stays under 65c while playing any game and my CPU stays around a consistent 60-70c

PC SPECS:

Case: Enermax Ostrog blk case w white
Power Supply: Thermaltake tr2 600w
OS: Windows 10 Home
Motherboard: alienware 0pgrp5
CPU: Intel Core i7-4770 3.40 Ghz
Memory: 8GB DDR3
Hard Drive: 1TB
Video Card: msi GTX 970 OC

your cpu has onboard graphics. I suggest you to take out the gtx 970 and boot up with the onboard cpu graphics and see if the problem persists. try running some stress tests with AIDA64 Extreme. if it doesnt crash/restart anymore then the culprit will be the PSU. If it still crashes then try removing all the rams and putting in one stick at a time and cycle the whole process again.

No sorry I viewed your reply from my email and picked best answer by accident haha. But I did take out my graphics card and am using my onboard to see If I'm still going to crash but I don't really know if when I am or even if I'm still going to since it's so random. If I still crash even with my onboard then I'm going to do the RAM suggestion. Thank you

Oh and I also ran Heaven Benchmark 4.0 for around a hour and a half and didn't crash at all

My first thought is also PSU, the TT has a dual 12 volt rail and neither carries sufficient power by itself for the rig, the big selling point for the TR2 is the low price, it doesn't show the 12 volt wattage in the specs so I would guess it's a 600 Peak and prob 400 to 450 continuous. Might also consider benching it as it may be shorting off the mobo, have a guide here:
