Sometimes shutting down windows I get this error saying ISTsvcWND is not responding...
I have no idea what ISTsvcWND is or does...I hope its not bad...
Ive been told its malicious and is related to the eo corruption Ive been experiencing in some of my computer games.
Anyone know what this is or how I could fix it, or even if it IS related to my video corruption problem?!

Its malware I havent heard any specific relation to video problems, but your video problems are probably just overall windows problems. To fix it first install ad-aware Se and do a scan, then scan with Spybot S&D, then download hijackthis and do a scan and check the box that has the ISTsvc in it.
