You can disable all non-MS items. I don't see anything mouse/keyboard related.

However, my BED time is coming, so I'll check on you TOMORROW K i did all that stuff in msconfig, still got the same problem :-(Go to the start menu and click "Run..."

Type in "dxdiag" and press enter.

Click the "Sound" tab.

Under "DirectX Features", there should be a slider BAR. If the slider bar is on any other setting other than full acceleration (No acceleration, basic acceleration, standard acceleration), then move it to full (all the way to the right).

If it's already at full and you are still having this issue, move it one notch to the left (standard acceleration). See if any of that helps.Also, undo all changes, you made in "msconfig". That was for TESTING purposes only.i also noticed that the cpu usage spikes very high when the choppiness occursYAY!!!  It's fixed!  Turns out it was the wireless internet driver, so I just disabled it and everything's working fine now.  Big sigh of relief lol!  Thanks so much for ur help :-)Good news
