I recently upgraded my monitor to a Dell 1905FP flat panel, and now I am receiving errors (program has encountered a problem and will be closed), where I previously didn't. The computer is a Dimension 4500, with a 2GHZ Pentium 4, and 512MB of RAM. The video card is a 64MB GeForce4 MX420.<br /> <br />Errors are popping up in Windows Picture and FAX Viewer, along with a couple of games (GTA2 for example will not even load).
