Howdy, Being currently defeated, I'm looking to see what I could've missed. I purchased mostly new from PCCG around six weeks ago: Ryzen 2700 ASUS ROG Strix B350-I Be quiet! Silent Loop 280mm AIO Team T-Force Night Hawk RGB 3000MHz 16GB (2x8GB) DDR4 Black Corsair SF 600W Gold MSI Duke 1080ti Spare Patriot 256gb NVME M.2 SSD Spare Patriot 480gb Burst 2.5" SSD Problem began immediately. Rendering device would drop out during Overwatch and random graphical glitches would occur on the screen. Event Viewer said that the GPU had lost power. The case came with a GPU Riser that people have complained does not have the bandwidth for PCIE 3.0. This was allegedly fixed in late production units. I RMA'd that and the problem wasn't as bad (i.e. happening at the desktop immediately when I log in) but it occurred within roughly twenty minutes of playing Overwatch. GPU or PSU, right? Swapped out the PSU for a 850W Corsair and it happened just as much. Swapped out the GPU for a 1050ti loaned to me and the issued occurred without change. So that leaves: RAM, Motherboard, CPU, Still the GPU Riser, temps, software. RAM- Ran a USB MEMTEST for nine hours without issue BUT the issue isn't as bad if I only have one stick of RAM in. No XMP profile enabled either. Motherboard- Not sure how to test motherboard. CPU Temp doesn't go much higher than 35-45. GPU doesn't go above 83. Even if I force the GPU to 100% fan and keep it around 60 degrees it still happens. CPU doesn't seem phased and I can OC it normally without it affecting how often the drop out happens. For all this testing i've had no OC. Been playing with it recently though. Software- OS Was a fresh install. Latest chipset drivers, among other drives. Clean install of drivers with DriverCleaner from safe mode > Install of latest Nvidia drivers. Check all sorts of meme'ery for reg edits for COM errors and such. Nothing has helped. ONLY TEST I HAVEN'T DONE - Remove motherboard from case and test without riser. It's so much work... What do you think it could be and why? Thanks in advance.
