Re: computer keeps resetting
This blus screen you speak of wouldnt happen to have a fatal error screen would it? you would be able to tell if there is a bunch of text on the screen.
unfortunately though, it sounds like you have a virus that has affected the boot sector of your system. the best way to ensure that the problem is solved is to format your drive and create a new partition.
if there is info you are needing to save you can try a data recovery program that runs without the use of the hard drive, like the one here, http://download2.lsoft.net/BootDiskDemo-Setup.exe
this is a great tool since it boot from the disk you creat instead of your hard drive. from here you can save any docs or info to an alternative storafe device before formating.
use this tool and allow it to run a complete check and get back with the results

It sounds like a hard drive failure. Try to test the hard drive in a desktop system to see if the data can be read. If so, copy everything you want and attempt to run a diagnostic to evaluate the derive. You likely will only get one chance to recover the data, so be sure you do it quickly. Start here to find a tool to test the drive in another system AFTER you have tried to recover any useful data ( pictures, music, documents, etc)
It sounds like they had something with that last entry; if you've used it a while it's common for the wires connecting the screen to the machine to fail, resulting in about what you described. Of course you've tried the monitor hotkey (for switching simultaneous/separate display with connected monitors) already as well as closing/opening the thing to see if the display reconnects for the moment....
Otherwise it's pretty vague what might be wrong; it could be a PC CARD cellular interface came out a bit or caught EMI, knocking out the system board (permanently or not) or any number of screen (and connection) related issues. Try running with an external monitor, looking for junk in your laptop's ports, and certainly swapping out your hard drive with one you don't mind sending for warranty service (or at least completing some sort of backup on another machine.)
The system restore probably undid something really essential for the computer to work properly. Try hitting F8 when the computer is booting up, boot into safe mode, log in as admin and try to undo the last restore you did.
you are right insaying that is video porblem. here is the fix.
This is what appears to happen.during the installation of the most current drivers 100.65 Vista, an OLD file nvlddmkm.sys is copied into windows/system32/drivers and not the current one in the install. As a result the new drivers are attempting to access a file dated 11/2006 instead of 2/2007 ver 7.15.11.0065 which is in the newest WHQL driver ver 100.65 vista 32.
Fix: Go to windows/system32/drivers and rename nvlddmkm.sys to nvlddmkm.sys.old. Go to the nvidia directory and find the file nvlddmkm.sy_ and copy it to windows/system32. Using the cmd window (DOS box) type EXPAND.EXE nvlddmkm.sy_ nvlddmkm.sys. When the expansion is complete, copy the new nvlddmkm.sys to windows/system32/drivers and restart the computer.
Your computer should now work properly.
You will notice that any uninstall and reinstall of nvidia drivers will not remove the old nvlddmkm.sys file and will not overwrite it with the newer version. You have to do it manually. I do not know why this happens but who cares as long it is fixed.
Power down your machine
Unplug everything from it
Open it up
Remove your sound card and put it back in
Reverse the step and boot your machine
If it still doesn't work then you'll need to replace your sound card. You can find really good ones on Amazon for $25 or so.Remember to always turn off your speakers before you plug them into your computer. Since they are probably powered via AC adapter that surge of power could have shorted out your card. Good luck!!
Best way to fix it is using "Last Know Good Configuration" option in advance boot menu by pressing F8 during the boot. If "Last Known Good Configuration" doesn't resolve the issue, You may you use System Restore option to earlier date that can be prior to the issue. Please post if you need further assistance.
