Troubleshooting Process Help

[gordo865]

I'm having some issues with my computer restarting on its own while gaming. I've already done basically everything I can do software-wise to fix it. I've done DDU (several times with several different driver versions), a windows in-place upgrade, BIOS update, etc. I'm planning on doing memtest86 tonight to see if it could be my memory. The windows memory test, of course, said there were no issues. My next check after memory is the PSU, but I have no idea how to test that. Is there any way to do that? If not do I just contact Seasonic (There's a 10 year warranty?) and see if they'll send me a replacement and hope that fixes it? I've never had to replace parts before so I'm not sure what happens when troubleshooting fails.

Are you having temp issues? My only experience with this was when my CPU cooler was failing and I would reach temps when rendering video that would prompt an auto shutdown.

First thing to check is always an overheating issue, what's your Temps while gaming ?

Temps aren't the issue. GPU hovers around 75 under load and CPU never gets above 65. I'm currently trying to run Memtest86, but for some reason no matter how many times I image it onto a USB drive, it refuses to show up in my bios as an option to boot to.
