My laptop (vista home premium, 32bit) Toshiba keeps freezing. It even sometimes flashes blue with no writing just blue and restarts. Ive turned restart off during system failure but the screen stays blue.
W/o knowing the stop errors, it will difficult to say whether is your drive or something else. Unfortunately for you, I know there is a place where you can check your errors, I never remember where it is.
yes you want the auto restart turned off , when it bluescreens you'll see in the bottome left a memory dump being created , it will count up to 100% , when its done reboot manually then goto C\windows\minidump zip up the contents of that folder and attach it to a post in this thread
we can take a look at it for you and maybe come up with some ideas , it would be better if you could attach three or four
