Hey guys, i have a serious problem with my computer. About half a year ago i bought a SFF Dell Optiplex 790 and upgraded it with 1050ti. Yesterday my mouse started flickering and after a while stopped working. After i restarted my computer, it worked fine again. Today the same thing happened except my keyboard died as well. I tried other usb ports, both up front and back. Tried working on Linux based OS for a while but after a while both mouse and keyboard stopped working again. I dont really wanna buy a new case, psu and mb just bcs of this.
