I've been having a problem with my computer for a few months now. I kept hoping I would stumble into a solution, but have been unable to. I think it is a malware problem, but I've been denying it because I tend to protect myself from it pretty comprehensively.
The computer boots up fine, without any problems, and seems okay. After some time though, sometimes minutes, sometimes hours, the computer will freeze, or hang up. This only lasts for a few seconds, with everything freezing, even the audio (Which results in an annoying screeching sound if there was anything playing at the time) and the temporary interruption of any program I am running at the time.
After that, the computer recovers, which takes about a half a minute, the computer works, but with some quirks and slowness. The mouse cursor acts odd, not showing the proper symbols when I hover over something (I'll see a finger pointer over text, then the text editing symbol over a hyperlink, ext) And if I continue to move the mouse, especially in windows, the computer will continue to hang up every few minutes, this time only lasting for a few seconds before resuming. The freezes do not seem to occur when I do not use my mouse (it has not happened for the entirely of me typing out this message). There is also some general slowness on all programs, with games running in half the frames they would before the freeze occurred.
I've tried to look online for hint of what has happened to my computer, but as you can imagine, vague sounding problems like "Computer freezing" will get dozens of results which will have nothing to do with my problem. So I don't see any recourse but to lay my problem out and hope someone has any suggestions besides wiping the computer or taking it to a computer shop.
Any help would be very much appreciated.
