This issue started early last week with my laptop. It boots up just fine, but after about five to ten minutes of usage, applications slow down, then eventually stop responding altogether, and I have to restart my laptop. These applications include important ones such as the screensaver, desktop, and taskbar.
I've had to boot my laptop in Safe Mode every day for the past week just to get things done. I tried running not one, not two, not three, but four deep scans, all of which lasted over four hours. The antivirus programs couldn't find any malware, which leads me to believe that this probably isn't because of a virus. Now, I don't want to make any assumptions; it could very well be because of malware, but my laptop doesn't normally do this. I've run a check through every application I've installed, and they all came up clean; no malware.
I've also tried going into the Task Manager and closing out programs that I don't need running; doesn't work.
Please help. I don't want to keep having to go without sound and other services that are available to me in Normal Mode, but not in Safe Mode, because it'll eventually cause my work quality to suffer.
