I was looking to replace some parts in my old computer, and in a freak accident I dropped the motherboard and destroyed it. Using the AMD Phenom II X4 965 Black from that, along with my old hard drives, I put it into a new build with a new case, motherboard, PSU, fan, graphics card, and RAM.
I thought it was running well for awhile, but I've been having random issues. For example, I can barely start tf2, and it chugs along at around 5-15fps even on the lowest settings. I can play overwatch on pretty high settings at 50FPS, but I have a friend with a similar build who runs it at 70FPS.
Hard drive is wdc wd10eads 11m2b2
CPU:AMD Phenom II X4 965 Black
Ram: 8GB EVGA DDr3 SuperSC, 2400 (4gx2 kit)
Motherboard: 970A-UD3P, gigabyte
Graphics card: Asus Radeon R7 360
OS: Windows 10
I did a clean install of windows 10, didn't keep any files. Is there any obvious reason why I should be having issues?
