Might be a software conflict with DEP. If Intel processor, check the BIOS to see if there is an option to disable the hardware DEP. Otherwise, get into safe mode, right click my computer->properties, choose advanced, click settings under Startup and Recovery, under system startup, click Edit.
Under the list of operating systems, make a copy and append " NoDEP" to one of the name, the /NoExecute=OptIn change to /NoExecute=AlwaysOff.
Save.
Reboot and during bootup, choose this NoDEP OS.
Let us know if it works. Might be something you installed.
nope. it is AMD. so does it still matter with DEP?
