I have no idea what is going on with my old laptop... but its ram usage keeps going to 80%+ while simply idling. It has 4 gigs of ram and nothing else is running other than MSN. I thought it was an overheating issue. Its not, I have a room fan under it cooling it. I thought the RAM was corrupted... Its not, put it in another computer and it ran until the harddrive ended up crashing. My brother has to use the spare and I need to fix it since his computer was the one crashing <3 Please help. This computer cannot stay on for long virus scans and malware scans may be out of the question. He was able to run Dungeon Fighter last night without having any real issues... The ram usage stayed at 45 - 50% (The game is hard on the RAM) Could there be something wrong with the system idling?
