WinxpHome Shutdown

I am running Win XP Home on a no name computer. The computer constantly restarts for no reason. I stopped the AUTOMATIC RESTART ON FAILURE and am getting this error message.
STOP: 0x0000008e (0xc00001d, 0xbf8776f9, oxf385cc48, 0x00000000)

Win32k.sys – address bf8776f9 base at bf800000, datestamp 3f73195d.

This is driving me nuts. Windows Error reporting states it is a problem with a driver but does not tell me what driver.

Any help would be appreciated.

Thank you,
