CMOS accessibility problems with my Microstar K7t Pro (6330)

[brouillet]

Why is it all of a sudden that whenever I want to access my CMOS settings on my Microstar board (6330) that after hitting the [DEL] as instructed it simply goes to a black screen with a cursor at the top left? The manual also suggests holding down the [CTRL]+[ALT]+[ESC] as an alternative, but sometimes this also gives the same results.

I've also been in the PC Health section on the CMOS, where the CPU temps and fan speeds are tracked and have had the PC lock-up completely.

Help!

* AMD Duron 750 (not overclocked)
* 128MB Crucial CAS2 RAM
* Creative Annihilator 2 MX

Thanks...
