Why my PC is freezing without crashing, coming back up.?
TLDR: PC freezes randomly for 10-20 seconds with sound glitched, but never crashed/turned off/BSOD'd, always comes back on and works for a few more hours/minutes/seconds before freezing again.
Motherboard: ASUS PRIME H270-PLUS MINING CPU: Intel Pentium G4560 RAM: Patriot Viper Elite gray (2x4GB) DDR4 2666 (running on 2400 due to MB restrictions) SSD: Kingston Now A400, 2,5" - 480GB GPU: GIGABYTE R9 270X 2GB PSU: EVGA 450 B1 - 450W All part except the GPU are new and I put the rig together myself.
The PC freezes from time to time. It seems to happen more often when gaming, but it happens when using browser or just Windows too. Sometimes it doesn't freeze for hours, but usually it happens on average every 5-10 minutes in-game and less frequently in Windows.
It stays frozen for about 10-20 seconds and then comes back on, working normaly until the next freeze. So far it has never crashed or displayed any error whatsoever. There are no graphical anomalis, the picture just freezes. But there often are sound anomalies, meaning the in-game music will loop for a few second before the whole system freezes and the sound is often looping even while the system is frozen. Interestingly when this pre-freeze sound thing happens, I can stil move my mouse and the game still runs, even displaying in-game information when I mouse over it, but once I click something, it immediately initiates the freeze (if I don't click anything, the freeze happens after a few seconds anyways).
The freezes seem quite random in-game, I've been unable to trigger them by doing system-demanding actions and they happen even when I'm not doing anything and the game just runs on its own. I've tested them in Crusader Kings II (low demanding game with avg. 140 FPS) and Dishonored 2 (high demanding game with avg. 45 FPS). There is no FPS drop before the freeze (I have FPS counter displayed), no evident performance issue. In Windows they do seem to be related to my actions as it almost never happens when doing low demanding actions like typing this post. When trying to locate something that might cause it in BIOS, it ever froze in BIOS - though my MOBO has some Asus BIOS utility/interface, so I'm not sure if it wasn't cause by this ASUS thing instead. However in this case it didn't come back even after a minute and I had to hard reset, thankfully nothing broke and the PC booted up.
Thanks for any help. Amanda
