================================================
i scheduled a check disk and said that the hard drive is clean but once in a while windows still do a consistency test and reports that there are errors. i ran my virus/spam scanner and found nothing. my hard drive is only 2 months old and no weird noises when it loads.
also, firefox crashes a lot. supreme commander, cs: source, quake 4, quake wars crashes after long play (bout 30 - 45 minutes) and my system isn't overclocked
Hard Drive Errors!!! Bad or Faulty HDD? 
Linear Mode
