Windows 2000 Pro - Running Slow, No Task Manager

[jav]

*New user alert *  

Hey there, set up is Pentium 3, 800mhz, 10gb hd, 128mb ram running windows 2000 pro.

Everything was running fine until I got the internet hooked up with a DSL modem today.  Now system runs so slow, i have numerous messages popping up saying 'bad image' and when i open the task manager it just closes straight away so I cant even tell whats running.  Also having trouble just opening most programs. I reckon a reboot is in order but I dont have the key for the Windows 2000 pro disc anymore.

Any help/ideas most appreciated.

Thanks, have reinstalled windows and everything is fine.  Only thing is that I only have a maximum of 16 colours and a res of 640 x 480.

Any help how to sort this would be most appreciated.  

I have a compaq v700 17" CRT monitor

You need to load the driver for your video card. What make/model is it? If onboard, what is the computer make/model? If you don't know, download and run Everest Home and let us know. It will tell you all of this and more:
