Hi, using a Packard Bell all in one pc, win 7 service pack 1. Up until last week it was fine, turned it off last friday, started it saturday, things seemed odd. Running really slowly, windows not responding messages, mouse cursor flickering around the screen in slow motion.
No software has been installed prior to this happening, nor any windows updates. Hard drive constantly chattering, and its locking up as i type this.
Booted into safe mode and ran malware anti bytes, microsoft essentials, and mCaffee virus scans, all coming up clean. I`ve unplugged external hard drive, printer and my Huey monitor sensor. Nothing changed.
Hmm, you appear to have two Anti-virus running - Microsoft Security Essentials and McAfee. This could well be part of your problem, only ONE anti-virus per computer, otherwise conflicts may and probably will occur.
