possible USB problems causes Windows explorer crashes

[Painterh52]

Hello, I have been wrestling with Windows Explorer crashes for a while now and I am wondering if a faulty USB system could be the culprit. My system is about 9 years old and is an AMD 939 platform. The specs are:
Motherboard- Asus A8N-SLI Deluxe
CPU: AMD Opteron 170 Dual Core @ 2.7 ghz
Ram: 2 pairs of 1gb Corsair XMS Twinx running with 3-3-3-7 timings (total 4gb, dual channel)
Graphics: PNY Nvidia 620 GTX
Hard Drives: 2x Seagate Barracuda 7200 rpm drives
Logitech Fusion webcam (USB)
Logitech PC speakers w/subwoofer
Logitech MK710 wireless USB keyboard
Logitech M570 wireless USB ball mouse
Windows 7 X64

The only reason I am suspecting a USB problem is that the Explorer crashes seem to be happening when I am either moving the cursor with the mouse or typing on the keyboard. Additionally, I previously had a 4 gb Sandisk Cruiser set up for Ready Boost, but somehow it became corrupted. if anyone has any ideas, I would love to hear them
