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.
