The reason your Dell and HP are having the blue screen problems is because PC's BLOW!!! Seriously...they're like the Daewoo's of computers.

LOL seriously though....Try and run a "System Restore" or "System Recovery" if that's all you can do. Either one of those should fix your problem.

I'm a Graphic Designer and I ABSOLUTELY HATE PC's now. I switched to Mac and I love it!!!! I will NEVER buy a PC again! I've had problem after problem with all of my PC's. I've never had a problem with my Mac and it runs just as fast as it did the day I bought it!

And it's not really the PC so much but it's their stupid friggin OS. Vista is the worst OS ever. I had XP on my laptop which had half of the RAM as my desktop but it was running XP and it ran twice as fast as my desktop computer which was running Vista.

Anyway, my suggestion is to run a System Restore. After that...buy a Mac
