Hello Everyone, I have a Dell Dimension 4600i. I recently decided to fire it up and make use of it until it's time ends. I've noticed it freezes a lot, usually while playing music or browsing the internet. I played Heroes of Newerth on it for over two hours a few days ago and it ran fine, so I don't know why it does this. When it freezes, the computer activity light (the one next to the power light on the front) is off, no blinking, nothing. It has a pentium 4 2.8ghz, 1.75 gb ram, varying speed, ati radeon 9700 pro. Any help would be appreciated, thank you.
