I just built a rig for myself, been about 5 months, scrapped parts from my old computer till i can get the rest. decided to stress test it to see if it could maybe handle OC for shtz and giggles. slightly long description after specs. my specs Operating System Windows 7 Ultimate 64-bit SP1 CPU AMD fx 8320 8core 3.50GHZ MOBO Gigabyte GA-970A-DS3P GPU AMD Radeon r7 240 (scrapped part) RAM 6.00GB Dual-Channel DDR3 @ 669MHz (scrapped part) PSU Atnec's TruePower Classic Series TP-750c-750W long winded explnation ok, so here is what i did, for 40 min i ran prime95. it maxed all cores to 100% load, and started up the fans in the comp. so after the first 3 min it went from normal usage temp of 23c to 50c, then slightly escalated to 55 over the next 17min. so i decided to see how a game would run during max load, so i rev up DBZXV knowing that it doesn't require all that much from either cpu or gpu. game ran smooth up till i have 4 characters on screen, hit with a tad lag but nothing to cry over. played fine for 10min. decided to really test it. I rev up ARK survival. after the horrendous load time for the game it starts up, i run around for about another 8 min or so, shift graphics from med to high, which of course makes frame rate drop and then almost immediately shift back down to med, then a few steps in game later my comp just shuts off completely. temp was maxed at 58C bounced between 55-57 during play. I don't think it was quite an overheat issue for the CPU, but i do think that i may be the GPU got overheated/loaded or PSU is faulty in some way and/or couldn't handle all the extra usage.
