Here's the problem - that particular error is usually caused by a problem with Hibernation. But you aren't using hibernation, so now we just have to guess. I'd like to try three things in this order:
First, please run a check of the hard drive. To run checkdisk, right-click on a command prompt icon and open as administrator. In the command prompt window type:chkdsk /r
(then press ENTER). You'll be told the disk is in use and asked if you want to run checkdisk on the next boot. Say yes, exit the command prompt window, and reboot
Then I'd like to check the ram. To check the ram, download memtest (http://www.memtest.org/
). Burn it to a cd using a dedicated .iso burning utility (http://www.petri.co.il/how_to_write_iso_files_to_cd.htm
), make sure the cd drive is at the top of the boot order in bios, then boot to the newly created cd and run the utility.
If the problem continues after that, I'd like to try a selective startup. But first please run the above two checks.
