I have a dell desk top xps with a Core i7,12GB DDR3 along with a Radeon HD card.2.2 years old and is just as fast as the day I hooked it up.
When I said dust could be a problem I meant inside the computer case.
Superantispyware had a update malfunction on the 29th of July and screwed up alot of computers.It effected older versions of microsofts 64 bit really bad.I happen to be running an early version of vista 64 and it gave me a challenge to remedy this last weekend.Took about 6 hrs. to get it done.SAS does not respond to there help forums over the weekend.
