I run perfmon /report and I got some error message about input devices. Someting like the PS/2 keyboard does not work properly tv_ConfigMgrErr24. I bought the mobo second hand, but the SSD is brand new and I installed the system with USB keyboard. I haven't used PS/2 for many years. I tried to find the driver in the device manager, but nothing PS/2 related is there. My current keyboard is Logitech K120. Any idea what this means or whether I should fix anything? I experience strange things with this keyboard, my windows sometimes lose focus when I am typing and it changes language when I press alt+shift in-game (afaik. it should not do that by full-screen apps). There is no virus on the computer unless it came with the motherboard. Eset Smart Security was the first thing I installed after the opsystem and I rarely download softwares without digital signature.
