I got my latest PC this January as a gift, an emachines T5212 w/ WinXP, 200GB HD, 1024MB RAM and it's been interesting from the start beginning with a start menu key that only functions on the 4th tap, but that I can live with, it's the other eccentric behavior that's got me perplexed.
1.) After a few hours of computer use graphic display malfunctions (taskbar & icons disappear, shut down window won't come up, clock time freezes.)
2.) Today it dialed up the Internet w/o me being anywhere near it.
3.) Resources say 89% free yet system sometimes freezes when running more than 2 programs at once.
P.S. I have 2 anti-virus programs, McAfee & AVG and each are updated daily.
