I had just done a critical update a few nights ago, and after rebooting my pc to finish installing, my reboot now takes 10-15 minutes. When the pc comes on and says ACER is where it sits the longest, and i dont think i can enter bios or change boot devices either, ive pressed and pressed the keys. I tried to system restore to a week or so back, no avail, also did a clean install of windows 7 ultimate, and still doing the same thing. Any ideas? Its a ACER E380 BIOS: Phoenix - Award WorkstationBIOS v6.00PG Processor: AMD Athlon(tm) 64 X2 Dual Core Processor 4400+ (2 CPUs), ~2.3GHz 4 GB of ram 320 GB Hard Drive Radeon HD 3650 Video Card Norton Internet Security Suite Windows 7 Ultimate I dont have alot of software at the time installed, just mozilla firefox, thunderbird and a media player. Once the computer is booted and at desktop there is no problems whatsoever tho.
