Just recently i have run into some problems with my computer. Its has vista ultimate on there. I first noticed it on utorrent. It kept saying that the disk was overloaded. Next dvd shrink has stopped while encoding and pausess for long times but then starts back up. Lastly Nero takes forever to complete a dvd. At first i thought it was DMA issues but i unistalled it and restarted my computer. The same thing is still going on. IS there any ideas. Also when i go into device manage under ATA channel 1 and then advanced settings there is nothing that says its in ultra dma mode under devices its just blank.
