I got the same problem with my WinXP pc. When using SEUS, after connecting the phone, it froze when installing SEMC flash device.
I managed to solve it by downloading A2uploader and ran it in safe mode. The SEMC flash device managed to install. Reboot the system back to normal and managed to update my phone via SEUS. But if you connect to a different USB port, the SEMC flash device will try to install and the PC will freeze.

Embong, yes, run windows in safe mode. Execute the A2uploader and connect your phone by pressing the C button. It should install the driver without any error. Once done, reboot the PC and run windows normally. You should be able to perform an update via SEUS.
