So i've been having a couple computer issues lately. 1. it takes 5min+ to start up / shut down. 2. when it starts up, it sits at a point where no icons or task bar show (only desktop bg). 3. pauses for a second or so every couple minutes while playing a game. 4. has slowed down in general and will be very "touchy" about what opens and how fast (if at all). Any suggestions? I have ant-virus/spyware and i have 2 reg cleaners. I know that is very broad, but where should i start?
