I am a fairly new member to Toms Hardware and I am very impressed with the level of expertise from the members and their willingness to reply quickly. I need some suggestions - I was given a Compaq evo n610c a few days ago. Just turned it on today for the first time - booted up fine. I ran a free disk defragmentation progrqam - defragler. It was 29% fragmented. When it got to 99% done, the system hung and the hard drive started making very audible clicking sounds (I assume read/write heads). Just for the heck of it, I booted into safe mode and was told to reinstall system32\hal.dll. I need the cheapest/refurbished/pawned/american pickers/habib's house of hardware/chet's food and grain/ wherever, just need a CHEAP fix. I believe the current configuration is 40GB HD (Multibay) part # 265495-001. Thanks!!
