Im using Windows & (64-Bit). Sony VAIO VGN-NS 330 J, Pentium Dual Core with 4GB Ram, T4200@2.00GHz. I recently got a wireless internet usb dongle from a local operator. Its a plug and play usb that installs its own software upon attaching. Since then i installed a few software as well. Now my computer seems to freeze up randomly from time to time. Sometimes a few minutes after starting and sometimes after a few minutes or hours. I have reinstalled the usb software and plugged it into a different port but it continues to hang up. I uninstalled the software, yet this problem is persistent. I lose valuable work and data and have to shut the laptop down by pulling the battery. I think this will also corrupt my windows. Please advise if this problem is relating to the usb, some software or is a bug.

Most likely a virus or spyware. Run an antivirus scan and remove any unknown startup programs. You may have to remove things from the registry. If you aren’t savy enough you can always bring the computer to a repair store.

    I just spent three days discovering that the default ram voltage on a motherboard may cause intermittent freezing/BSODs when the ram slots are maxed out. You can run Memtest 86+ for 10 passes without errors. The dump files will show different drivers when the boot error occurs. When the system does boot without error you can run burn in tests for two days without fail then turn off the system and it will freeze on restart. 

    I increased the ram voltage to 1.8 volts with all four slots filled and the error never recurred.

    Good possibility. It's an example of why diagnosing this type of question in an on-line forum is often pointless. The number of possible causes of "freezes" is very large. -- Tom

    Sounds like a backup and reinstall may be in order.
