Hi, My computer runs pefectly when I am on word or msn, internet playing music etc. it multitasks very well indeed but when it comes to playing on games its not so good. At first when i installed colin mcrae rally 2005 on it it ran perfectly with very smooth graphics on full detail. then after a few weeks whilst in game play the whole game would speed up and me not being able to control the car. It would do this every now and then and i would loose control of the car but now its like that 100% of the time.eg 30 mph looks like 100mph. It also did the same thing on toca race driver 3 - fine at first now unplayable. I want to be able to sort this problem out without wiping the data off the hard disk and re installing windows because it takes so long setting it back up again. Any help would be much appreciated as I am loosing my patience with it now !
