Audio pops and crackles, everything is slow, cursor movement is choppy and disk usage is always around 90%, even with no applications running. I've tried disabling services in command prompt and still nothing has changed. I suspect it may be a hardware issue as at one point the fan sounded like something was in it and stopped working overall for a little bit. I opened it up and now it seems as if it is overworking itself. I have a HP Notebook, not sure of all of the specs but if someone thinks they could help I can post them. Help?
