Firstly, just to clarify, my problem is with a few games (Splinter Cell, DX: Invisible War and, to a lesser extent, TR: Angel of Darkness). I realise this means it is, more than likely, a problem with my system rather than the games but since Splinter Cell is one of them I thought this might be a good place to ask for help.
The games run absolutely fine at first but then lock up, for no apparent reason, to a pixellated screen (screenshot). Once locked the only thing I can do is to press the reset button on my system unit as nothing else will revive the system.
I'm not sure how relevant this may be but Angel of Darkness is the least affected and has only locked up a couple of times after prolonged play. Whereas, IW and Splinter Cell both tend to lock up after about 5-10 minutes making it impossible for me to play them.
I have installed all the necessary patches and all my hardware drivers are bang up to date but to no avail.
My current specs are:
Windows XP Professional (5.1, Build 2600)
Athlon XP 2500+ ~1.8GHz
nVidia GeForce Ti 4200 (128MB)
Creative Audigy Player
I was told that, in situations such as this, DxDiag is often useful so I ran it and have put the resultant text here
Any help would be greatly appreciated as I really want to play both Invisible War and Splinter Cell.
