explorer exe cpu usage

When I do certain tasks like "show desktop", use Windows Media player 11, or open up IE7 my computer will hang for 10-20seconds and will show Explorer.exe using as much of my CPU as possible, ensuring my total CPU usage is at 100%.
It does this quite frequently, I was wondering if anybody had a similar experience and found a solution, or if there are any suggestions.
My System is as follows
Vista Beta 2 AMD 3700+ Nvidia 7800 GT 2 Gigs of Ram 300GB Harddrive
Thank you.

Does disabling Aero affect? it sounds like graphical issue and how display adapter handles requests.

Did you ever install any antivirus or other "uitility" software? I had a similar issue when I had installed CA antivirus trial... Once I got rid of that all went back to normal.

I have this same problem and I use CA anti-virus. What other anti-virus are people using? -- AMD-FX-60 2gb OCZ Plat. memory ATI 1800 AIW 2x74gb Raptors in RAID-0 2x400gb WD HDD in RAID-1 Epox Nvidia-4 Ultra M/B Senior Member Overclockers.com

Jason you rock! I got rid of CA's anti-virus and all is good. I am using PCillian's beta and it's working flawless. -- AMD-FX-60 2gb OCZ Plat. memory ATI 1800 AIW 2x74gb Raptors in RAID-0 2x400gb WD HDD in RAID-1 Epox Nvidia-4 Ultra M/B Senior Member Overclockers.com
