Helloo All ... I have a Compaq Presario V2000 with 1 GB of RAM. The unit is about 18 months old and has never had windows reistalled. In the past I would experience random shut downs when I would try to burn a CD. Now it's been shutting down when I'm running programs such as Word or Macromedia Dreamweaver. It seems to be OK with internet browsing and the like. I just finished up taking off the bottom of the laptop. I blew out was minimal dust there was and reassembled everything. I can hear the fan turn on every now and again. I downloaded Adaware and removed 72 items. I downloaded McAffee and the laptop continues to shut off during the initlail scan. I rebooted in safe mode and running McAffee yielded the same results. The laptop turned off mid scan. I download Speed Fan and the tems are HD 45C and 61C for the CPU, I think. Running McAffee again has the CPU temp spike at 68 to 80 depending on CPU usage. I'm totally confused now. It has shut down during McAffee, Dreamweaver, Word .... Am I due for a hard drive wipe out and OS reinstall? Thanks for any and all help!
