Posted November 15, 2015 Hi Guys, I need help with the following as I have no other idea what I can do with my PC to get it work as it supposed to. I did a lot of research and tried every single advice I found on the web but everything was unsuccessful. I built a PC about 2-3 months ago that's keep crashing since under load, like games, but not when stress-testing either CPU, RAM, GPU, even all together. When a crash happens I don't get a BSOD or any error message, just freezes the screen and I also got a buzz through my sound system. When I was looking for the cause of the crashes, I figured out that the RAMs were failed my memtests so I sent them back for exchange, but my problem was still there after I got the new ones. What I've done this far are memtests, stress-tests (cpu, ram, gpu, ssd), checked windows event log and memdump, reinstalled Windows 10 (formatted SSD, clean install), cleaned CMOS, PSU self-test shown everything is fine. I also disassembled and reassembled the whole PC (except cpu and cpu block as I don't have thermal paste) to make sure there's no any contact problem. Everything is running on default, RAMs@2133. My temp are all fine CPU 24-25C idle, 40-45 under 100% load, GPU 30 idle and about 60-65 under load. Drivers are all up to date and I don't use beta drivers. My BIOS is the latest official one.
