I've been playing WoW (world of warcraft) for a couple years now. About a year and a half ago I replaced the video card in my computer. The fan quit working and it fried the card. Haven't had any problems with it. Recently I've had a problem with frequent disconnects and intermittent lag. I've tried a defrag and shutting down unneeded processes. I've also tried playing with both my firewall on, then off and there's really no difference. I ran a virus scan and no viruses were found. I have 70% free space on my hard drive, so I know my computer isn't overloaded. WoW is basically the only thing on there besides some music and photos. Is there something I'm not doing to fix the problem or is it a WoW issue? Has anyone else had this problem recently?
