HELP!! iTunes music skips videos wobbly dragging

HELP!! iTunes music skips videos wobbly dragging

I have a dell desktop 4600i w/ SP3 Pro 32bit (Microsoft Updates automatically converted my reg XP SP2 Pro 32bit to SP3).

I recently re-installed my reg XP SP2 Pro 32bit on my pc because it was going super slow.
It's now going fast/normal again except for now my iTunes will easily skip non-stop if I do ANYTHING else on pc while muisc is playing, plus any/all videos I watch online or on cd/dvd drive ALL drag and sound wobbly.

A couple things that seem different from when I first installed XP was that after I re-installed XP I couldn't connect to internet so my Belkin router took over and did it, which I did not happen last time. Also, I'm pretty sure that before this re-install I had the NVIDIA GeForce thing (sorry not computer lit or a IT tech'ish) on my computer. Now it seems to be all ATI stuff for video and graphics, etc.

I tried ALL the suggestions from the Parkk thread "choppy sound on DELL Dimension 3000" but none of it helped/made a difference.

Here's my log from HiJack This:

Thanks but no, nothing highlighted in yellow nor is it falling back to PIO mode. It always stays in DMA.
