Hi! I have OCZ Platinum XTC DDR3 2000MHz 8GB KIT that loads up to about 60% of total usage after a hardcore Counter Strike Source session. When ive closed the game, it remains around 50-60% of usage, so i have to rs my pc to get it normal again. The normal usage is around 20% on idle, so I find this very strange. Could anyone help me with this? Thanks in advance!
You can try memory cleaning software for things like that. Here's one for you to try, it's free --> Memclean
What OS? This seems normal for Vista/7. You will want to look at your available RAM in the performance tab of Task Manager, it should be significantly higher after closing CS than it was with it opened. Free RAM doesn't mean much unless your available RAM is also low.
