OK. This is driving me absolutely nuts. On a new Asus A8jm laptop with Core Duo, 1gb ram, 100gb drive, blah blah blah. Has been working fine since i bought it two months ago. Last weekend I installed Paragon Partition Manager to do some work on an external firewire drive. Never touched my internal drive with the software. Now when my system boots, I get the Windows logo and then the screen goes black and startup stalls for approximately 65 seconds. Then it proceeds with the startup just fine and the system is stable and normal after startup. The timeout / stall / hang is always the same length of time. During the stall there is no hard drive access or any on-screen messages. I uninstalled paragon and did see an "autochk.exe not found" error on one reboot, but not since then. So far I have tried all the tips and tricks in autochk.exe not found postings, including: chkdsk /f chkdsk /r clearing BootExecute in the registry and adding an "autocheck autochk*" removed the Asus RECOVERY partition from the boot volume resized the boot partition to take up the whole boot disk used fixmbr and fixboot from the recovery console created a bootlog and examined it...nothing unusual in the log Tried system restore, but for whatever reason, I can't see any restore points beyond yesterday Nothing has made a difference. Anyone have any ideas on what else to try? I'm nearly at my wit's end!
