Another solution for "Slow Computer" symptoms: Hard Drive Transfer Mode

Already defragmented the computer? Cleaned out Temp files, ran CCleaner, created new user profiles? Even gone so far as re-installing the operating system, and the system is still just as sluggish? Read on..

The problem may be that Windows has switched the transfer mode of the hard drive(s) in your computer. NOTE: This is for IDE/PATA hard drives, on Windows XP.

1. Go into the Device Manager 
2. Expand IDE ATA/ATAPI Controllers
3. Select the Primary IDE Channel, go to Properties 
4. Click on the Advanced Settings tab
5. Check to see if Current Transfer Mode is PIO or Ultra DMA Mode 5. If it is PIO, that is your problem. 

To fix this you'll want to simply uninstall the Primary IDE Channel device and reboot. Windows will automatically detect and reinstall drivers for it, setting the transfer mode to the default, which is Ultra DMA Mode 5.
