My computer is weird. Windows looses time. I thought it was the CMOS battery, I changed it. Still does it. While gaming, sometimes the keyboard just freezes. The mouse works while gaming, but like when windows opens it gets kind of stuck too. (keyboard and mouse are both logiteck MK270, use the same bluetooth connector. I changed the batteries, since they're wireless. No luck.) I have plenty of power from the PSU. What is happening to my computer? What can I try?
