Problems With New Graphics Card

The Other day i bought a GeForce4 Ti 4200 128Mb DDR SDRAM Graphics card, when i got home i inserted the new card into the machine after un-installing the old one, now i know that this card is ment to run on a AGP 8x but the man at the shop said it will run on any, but not as good as on a AGP 8x.

Anyway installed it and put the drivers on and did the basic routine of checking for errors before and after and also running Defrag as well, this all went well but when i went onto my games it seem'd to make them go even worse than my original Geforce 2 64Mb and it was all stuttery and not only that but when i updated to the latest drivers from the manufacturers site it kept on making my system hang and crash all the time (not even Ctrl + Alt + Del would work) and i would have to press Reset button on the front of the system, how can i get round this.I know it isn't solely the heat that is causing this thats why i am asking for your help.

I have also ran the basic Spybot and AdAware in conjunction with the ScanDisk and Defrag


Note = I have sought of figured that heat in the system might be an issue which i am already going to purchase a extra fan for the back as i have a spare space.

Can anyone help?

Hi Paul ~

How did you go about un-installing the old one?
