Alright. my buddy just got a new Acer Aspire 5570 notebook with Windows vista. He was playing World of warcraft and anytime it started to lag, the screen would go black and it for like a sec or less and than pop back up as if the monitor turned off sort of. I looked at his device manager and it said there was a error with Is Mass Storage Controller. So i went to the Acer Site and got the driver for it and reinstalled it for the controller. All the drivers were working and it seemed like it fixed the problem but it did it once more. I Minimized out and a error message came up it said something like graphics card stopped responding but is again know and it dissapeared. If it comes up again i will try to read it quick to get the full error message.... Im sorry if anyone gets confused.. just ask if u are.. also I Appreciate Any Help Greatly...!! "Display driver igfv stopped responding and has successfully recovered" Thats what the message said, it started doing it again I also know this is in a game and should be in the video game forum but i had it there a bit and trying to get some input quick Again Thanks!
