I have the ATI Radeon 9800 Pro (128 mb) and have found that whenever I have Limewire running, the computer will just restart randomly and then when I log back on, I get a message from the Microsoft Online Crash site saying that the error was caused by a device driver problem. This first happened a while back and then seemed to be cured when I installed an ATI driver update which appeared on the windows update service. The exact same problem started happening again recently however, when I installed a Tevion TV Tunder card, (so, this is the first problem). Second problem: To try to solve this problem I decided to download Catalyst, but didn't realise that that I needed to remove the old driver first. Since, that whenever I have Limewire running, the computer restarts randomly as before but the message now says the error was caused by a Graphics driver problem. Does this mean that Firstly, it was not the graphics card which was causing the problems in the first place, and Secondly, is this now a new problem caused by installing a new driver over an old one? Please help, as you can probably tell, I'm not very good at this stuff! Thanks in advance for your time! George P.S. I have noticed there are similar problems already discussed but i'm still confused!
