I had trouble with my emachines rebooting out of nowhere, so I came and started a thread and someone suggested I get a new modem driver. I went on linksys' site and got it. A little after I got that I noticed my computer has been lagging terribly. It takes forever to "warm up." When I want to play BF 1942 it takes 5 minutes to load a map. Then I get an error message saying explorer is messed up. Then another error message says I have a driver error. Im wondering if its that modem driver.

I cant seem to find it and delete it, and I dont know what to do.
Any help would be appreciated. Thanks.
