BSOD on startup , error 0x000000f4 . startup takes half an hour

so everything was fine when my laptop started to become very slow and i used to get the BSOD very often so i decided to recover the system to the initial state . i did that and everything was fine , then i updated the windows 7 service pack 1 and finished the installation and rebooted my computer , the start-up at least took half an hour at that time and the service pack 1 installation showed "not successful " i tried to again to update the service pack1 which showed 73.6mb - 892.6mb so i updated it again and again the same thing happened.

then i researched and found out that there is some problem with the windows service pack 1 and some daemon tools driver sptd.sys is also involved or something so i uninstalled daemon tools as well as windows 7 service pack 1 from control panel .

now the system is back to its normal speed once it starts up fully , and unless i switch it off there is no problem , but when i restart the system it takes at least half an hour to start up sometimes more than that , sometimes it never starts and i see the BSOD after the welcome screen with error 0x000000f4 and the physical memory dump fails with error 0xc0000010 .

i had also found something about minidump files which i didnt understand anything about , but i still tried to find the folder but i couldnt find the minidump folder in c:/windows/ so i figured maybe i didnt have a minidump folder.

any help would be really appreciated , and if you decide to help please do so thinking that you are explaining it to a person who doesnt know much about computers .it would be easier to follow .

thanks :)



note : when i tried to run the minidump in sf diaog tool ,a dialog box popped up saying "no minidump found"

Little that I can do without the dumps. Try in safe mode does it work?

Sounds like a driver. Take a clean boot.

Yes you can, but check for which programs will not be included at start up. For example make sure that the anti virus loads at startup etc.
