Two weeks ago, I built my first pc and for 3/4 days everything was fine. The most intensive activity I do is gaming. One day, the pc randomly shuts down (no warning, no bluescreen, just powers down) while I was in a game and I couldn't turn it on until I turned off and on the power on the PSU. Remembered i didn't updated the bios version, did that. The next day no problems (did a full day gaming) and the day after, another random shutdown, this time while watching an episode.
Then I double checked that everything was in place, Ram sticks weren't. The sticks were in A1, B1. But according to the manual, the best configuration is A2 and B2. So i changed that. And i ran prime95 for stress testing the cpu and mem86 to test the ram, 75ºC peak temp on the cpu and no errors on the memory and, specially, no shutdown.
A day went by (I played an GPU/CPU intensive game on that day for 4 hours) and on the next day another shutdown and not turning on until i resetted the power supply, while gaming. Reseated cpu and cooler, cleaned it with alcohol (waited for it to evaporate), reapplied thermal paste (size of a pea, double checked with a friend).
The day after that, used prime95 again to test the cpu and the pc didn't turn off. The other day once again shutdown, while gaming. Resetted the CMOS and for a full day no problems. Next day, another shutdown.
Then I tried to take a ram stick out, run memtest64 no problems, played 15/30 min and down, switched the sticks and same. Then I inserted the two ram sticks and remembered that while researching the problem I read that some people had problems with the MOBO rgb and that I tried to uninstall Asus aura and only the aura service was uninstalled, the program wasn't. Next day, at the end of the day another shutdown.
So, I did a fresh install of windows.
Next day no problems, but today (one day later) all morning was turned on, played a game for like 1 hour in the afternoon without problems, made a break from gaming, switched games and after 30 minutes another shutdown. Then went to bios to change the ram profiles. Tried both DOCP profiles and at most 5 minutes the pc shuts down. Resetted power supply and didn't even get to post, down instantly. Tried 4/5 times same thing. Then waited a little bit, finally managed to get to bios and changed performance enchancer back to auto. Got to windows. Turned on a game to test and you guessed it shutdown.
As the time of this post, pc doesn't stay on for 5 minutes, idle
Sometimes the pc gets stuck in boot loops. rarely tho
Any more tests that you can think of ?
