CPU usage 100% when reading/burning HELP!!

Postby cd pirate on Tue Dec 23, 2003 9:18 pm

just recently this problem started. what happens is when i try to read any dvdrom it goes sooo slow. i tried RNM and dvd decrypter. what happens is it is always going down to 1x when reading and i couldnt figure it out. i then went to task manager or whatever and i ran it when this prob was happening.

i found a direct comparison. when the cpu usage went up to 90-100% the reading slowed down when it went down it sped up. its driving me crazy, this wasnt happening before, why is it doing this. i have DMA enabled, i tried this on my dvdrom and on my 106, same story!!

it even happens when writing. but when im not doing any read/writing the cpu usage satys at 0% WTF is going on.

please somebody help! i cant burn at 2x or 4x reliably cause the underrun protection keeps kicking in becuase of the cpu usage and my burns are hell slower.

i already went into msconfig and diabled every program except system tray but still the problem occurs. BTW i have winXP home edition.

Make sure that DMA is enabled for everything; it should never be disabled.
