My Music folder causing 100% CPU usage

[Code_D]

I have been trying to find a solution to this problem for a couple months now, but have not found anything on this particular problem. When browsing the My Music folder, it will hang for a couple seconds, then resume. The CPU usage for explorer spikes at 100% and does not drop until I stop looking though the music in the folder. Some have suggested that it is due to the number of files in the directory, but my other computer has more than this one with no problems.

Specs:
Windows XP Pro SP2 with all updates
Gigabyte 775 MB with Intel 945PL chipset
Celeron D 331 (2.66 GHz)
2 X 512MB DDR2 533 Ram (Dual Channel)
ATI X550 PCI-Express
Seagate 80GB SATA-II HD
Lite-On DVD-RW
MSI CD-RW

It's not a big problem, but is rather annoying. Thanks for any suggestions.

how fragmented is the drive? What detail level do you have the folder on? Thumbnails, icons, list, etc?
What are the memory levels of the two computers? Same, different.

I actually haven't checked the fragmentation level, but it has had the problem since the music was transferred to it. That was shortly after it was wiped and reloaded. As far as the detail level, it is in the detail view, with the file name, track title and artist, and other similar items. There are no thumbnails or other images of any kind being displayed in the folder. The computer having the problem also has double the ram of the computer that (wasn't) having the problem. (It is now experiencing the same problem.) Some forums suggest web content, but as far as I can tell, the web content is disabled on both systems. The only similarity of the two computers is that they are both Intel CPUs.. The first one to have the problem is a 775 and the other a 3.06 GHz 478. Just speculation, but is it possible that it is due to a Windows Update?

Update: The problem can be solved by scrolling through all of the music in the folder. After that, everything scrolls smoothly. Also, the CPU usage on the 478 system stays around 60% when scrolling. The 478 is HT enabled, and the RAM has been upgraded to 1GB, but there has never been a problem with available memory. Maybe a hard drive bottleneck?
