I have a Dell Laptop 1525 Inspiron purchased about 4 months ago. I installed Yahoo messenger and MSN messenger. VIsta would not let me use Yahoo messenger. The screen went black as I was typing a message and the computer shut down. When I hit the on button it is as if nothing happened. The chat window is still there and any other windows I had open before. As soon as I type a few words it happens again! MSN seemed fine.
So I uninstalled Yahoo Messenger and tried MSN only. Now I cannot use it either as the same thing happens. I also tried the Facebook chat and it does it too.
I call Dell support who were useless! They said I needed more RAM so I purchased 4 gigs. No change. I called back and now they tell me its a software problem that'll be $69 before we'll talk any further! I didn't pay it. I tried Microsoft as its obviously an OS problem and even though this is a new copy of Vista they won't support it free! I am very frustrated and I hope someone here can help me.
