I have an acer aspire computer with windows vista basic. I don't know if it really does have to do with my nVIDIA hardware or software since i don't know much about computers. My computer is just a year and a month old. It all started when I'm doing my business on the computer like any other day and it just freezes. I have to restart my computer by pressing the power button since it's the only way it'll turn off and than the "hasn't been turned off correctly" screen comes out, it than tries to correct problem with system restore. It doesn't work. Sometimes a blue screen also appears saying:

"A problem has been detected and windows has been shut down to prevent damage to your computer.

if this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps:
Check to be sure you have adequate disk space. If a driver is identified in the stop message, disable the driver or check with the manufacturer for driver updates. Try changing video adapters.
Check with your hardware vendor for any BIOS updates. Disable BIOS memory options such as caching or shadowing. ...." etc.

i once layed this problem on yahoo answers and they told me to do this:
"don't just update,nvidia drivers,go to the web site download the latest
driver,save to the hardrive,my documents is the place to save,download
drivercleaner,go to add and remove,uninstall the nvidia driver,save nothing,turn off,restart,f8 to the safe mode run drivercleaner ,when done
restart,install the lastest nvidia driver save to the disk,reconfig your settings,before all this system restore back a day before the update"
but this sounds a little risky.

What should i do ?

Thanks
