My sister has a pentium 4 1.7 ghz with windows 2000 and whenever i TRY and run computer games from the cd drive the game are very jumpy and can not be played i have tried CHANGING the graphics card, added more ram changed the cd drive and the ide cables used to connect the cd drive.   other software that are run straight from the hard drive work ok.   The motherboard is a QDi Platinix 2 however i do not know which chipset manufacturer is on the board VIA, SIS or intel but i have tried installing the VIA IDE accelerator driver however this does not work so i am guessing it is more likely to be SIS or Intel.   Any assistance would be very much appreciatedFirst find out ALL the  information about the system.

What preceeded this? Has it always been this way? What background processes are running? Do you have Norton installed, by chance? Are you free of malware? What games?

See below.I have DOWNLOADED the software to see about all the computer information but as yet have been able to run this but will get back to u with the information.

to answer your other questions this used to be a works computer that was reformatted so that no work related information was on it, It has been like this since the reformat but i do not know if it was like this before as the use of the computer for games and stuff from the cd-drive was not used.   No norton is not installed. the computer has not been connected to the internet so i am guessing that the machine is free of malware.  i am unsure of all the games that she is having trouble with but i do know that one is ski resort tycoon.

i will probably be not able to get back to u with the other information until later in the week or early next week but thanks alot for all the helpThe games may require more computer power so be sure and list a few of them as well. We'll leave the light on.The games that are being used are the following:
wildlife park gold edition
ski resort tycoon 2
colin mcrae rally
command and conquer tiberian sun
and rollercoaster tycoon 2

from the few that i have looked at the minimum or recommened specs of the computer should be able to cope with theseRunning from the CD is slower and cause jerkiness all by itself as the CD has to be repeatedly accessed and it is inherently slower than a hard drive.

We still don't know about your hardware.Sorry for the delay i have finally got some information from the everest software you had suggested and that is:
