XP freezes @ log-in

Hi "all" ...
Am seeing this problem for the first time, the boot up goes fine, no problem. Its when you reach to the log-in screen that the problem occurs. I can put in the user name & password, and after i click enter ... the pc freezes :confused:

...Can anybody shed light to this situation on what i should do to resolve this:confused:

Will the PC boot into SafeMode (F8) ok ?

The first time i tried it, no.
Last night it did tho, and still froze up.

You need to blow all the dust out of the PC and make sure the fans are working. Get Memtest86 and run the test.

Aight ama try it. Thnx in advance

Update: am currently re-installing xp onto this hard-drive.
