Lately my computer has been acting up. It takes forever for the computer to go to sleep. I could tell because the inside has LED lights. It used to be really fast in going to sleep and would shut off almost 5 seconds after. Now it's around 30 seconds. Also, programs like Winrar are really slow. Winrar used to extract my files relatively fast. Now, it is very slow and freezes up my computer. It seems like a number of programs freeze my computer. I open up task manager and often see the programs that I have opened to be used 100% of the disk, or be highlighted red. Could anyone please help me as this is really frustrating?
