Never actually stated the "error" - but when trying to load a game = Halo2- which I have played on this computer 2 years ago with no trouble, it stated the computer did not have enough speed- it said the computer was only 1.0 ghz, when it actually is a dual core 3.0 ghz. When I look up the system in windows vista it says there is a dual 3.0 ghz processor. I also got a new printer- about 6 months ago- but when I bought/built the new gamer machine - this pc became the daily grind machine= emails, reports, homework,etc. - but when i hooked up the printer there was an error when trying to load the drivers for the printer as well. It also locks up when looking for Vista updates. So some type of windows processing is messed up, or I have a virus that kapersky, trend, or Avanti fails to find.
