Hello,
I have recently been having the same problems and went through all the normal channels of fixing the problems that appear. Being updates,running my hijack this and the free malware and virus programs on cnet. When that didnt help i pulled out the trusty alienware respawn kit still no dice.
I would agree on the resolution or acceleratioin but i am running a year old alienware
and the video card was top of the line at the time.
I started to notice these problems after the service pak 3 update so i held off on that and tried diffirent players both didnt seem to fix it.
Last option i am toying with is some sort of complication between the nVidia driver and some part of the software. As long as i can still play my games it isnt that important but i like my stuff to work a bit .When it doesnt it usally starts to cause other problems or your infected.
I have run the updater now and got all the newest drivers for both my video card, Monitor. and sound card.I have a few more idea's now though thank you guys.
My system is :
Nvidia 7900gt 256mb
Asus board
Dual-core ahtlon64 processor 3800+
Creative SB Audigy 2 ZS sound card
OS= xp pro
Monitor samsung sync-master 920 lcd if i remeber right.
Maybe that will spark something for you that it hasnt me
