4 in 1 divers caused problems with CD-ROM

Can anybody help... please??

I've installed the latest 4in1 drivers (4.37a) and "whoa" my Ultra DMA hard drive tripled its speed and everything seems to zoom along..... except for my CD-ROM.

I've run SiSoft Sandra and it checks out fine but when I run an executable from the CD-ROM it gives me the "this program has performed an illegal operation and will be shut down" message. I can't run anything from the CD-ROM anymore.

Anyone have any advice?

Regards,
Jace

Problem solved...!

I turned off the DMA setting on the CD-ROM. This fixed the problem described above. Then I installed the latest beta driver (11.1c) for the ASUS 6600 PRO SDRAM and the latest ASUS Tweak utility (3.18). Set it until it just started to show artifacts and notched it back a bit. Now I get ~2100 on 3DMark2001 and everything is stable... so far : )
