Stress Causing Frequent Crashes

[timothias]

I recently decided to do some upgrades custom build. I replaced everything but the GPU since it was only 3 months old, and the optical drive. Whenever I use anything stressful on my computer's CPU(i.e. watching Twitch.tv streams, playing video games like League of Legends) my computer will crash. This can force hard restarts, or it will sometimes reboot on it's own. I've received two kinds of BSOD's, x101 and x124, but they do not occur from most of the crashes. I do not crash on Youtube videos, average day to day websites, or any other basic programs.

I've been searching constantly through forums to find a solution to this problem for two weeks. I've run multiple tests including:

-switching to older GPU drivers
-making sure all chipset and network/audio/connection drivers are up to date
-Prime95(almost immediately crashes)
-Memtest86(did not run for too long, but it went fine. memory does not seem to be the problem)
-re-imaging the HDD 5 different times with full windows updates
-updating the BIOS
-taking the GPU out of the system and letting it run on integrated graphics(still crashed on prime95)
-formatting OS on new HDD(crashes still occurred)
-tried different PSU's
-double,triple,quadruple checking all hardware connections
-CPU temp and GPU temp are at optimal 25-35 degrees Celsius
-machine is free of dust
-underclocking the GPU with MSI afterburner
-changed out thermal paste for a different brand
-booting with only 1 stick of RAM
-Checking BIOS version(1801 for my MOBO, most current version is installed)
-All temperatures also seem to operating optimally as seen from HWmonitor

I'm out of options here. I work in IT and fix computer problems all day, but why it comes to my own setup baffles me. I brought my system into work with me and no one else could figure it out either.

Since I bought the parts under a 30-day return policy, I took back the CPU/MOBO/RAM to exchange for the exact same parts. IT STILL EXHIBITS THE SAME SYMPTOMS. Before that I was pretty sure it was just a faulty MOBO. Now I do not know what to think. Here are my specs:

-ASUS M5A78L-M/USB3
-AMD FX6300 Black Edition(6 cores at 3.5Ghz each)
-CoolerMaster Hyper 212 EVO CPU FAN/Heatsink
-NVIDIA MSI Geforce GTX 650
-Ballistix 2-4GB SPORT DDR3-1600 RAM(8GB)
-Inland ATX ILG-550OE Gold Series PSU (Microcenter Comp/ Electronics Store's house brand)
-Antec 900 tower
-LG DVD optical drive(only piece of hardware that is about 7 years old, tried disconnecting, but crashes still occur)
-Seagate 500GB HDD
-Windows 7 64-bit Home Premium

Any thoughts are greatly appreciated.

A hard reset can only be caused by a power supply problem . A poor power supply could also be causing other failures if voltages were not stable

I checked out your psu . Nice paint job . Unfortunately once you get below that paint the technology is not good .
I'd replace it with an 80+ bronze or better psu . I suspect that will fix your problems

I thought I double checked the PSU. From what my friend and I could tell, it was the amperage acting too low with that terrible PSU. I checked at work with a new PSU as a last resort as per your suggestion, and it worked.

The amperage for the 12v rail was too low. It need to be around 21-25 instead of 18-21. I never thought to think of amperage when considering PSU's. Thanks so much for helping in solving my headache. Cheers.
