Windows 7 Strange Slow Response to Refreshing

[ruggb]

If I change something in WE nothing happens until I hit F5. Or maybe wait 2-3 minutes.
I installed a program and clkd to open - nothing happened so I assumed it didn't work in W7 and removed it. A few min after that it opened as many times as I had previously clkd it.
The same thing happens when I insert or remove a USB stick or a disk in the dvd drive. With WE open it is not acknowledged for many minutes even if I close and reopen WE.
Clking on programs has no delay - they open immediately.
It is a new HP compact size DT.

What might cause this?????????????
I have tried a number of things including offing the AV software (Vipre).

thx

First, I always recommend a system restore to a date before the problem started occurring. Then continue.

Try turning off Windows Search and indexing:
Turn Off Windows Search

A throw in the dark:
Someone posted a specific solution for him:

I found that in Task Manager the app that was pulling down Explorer was "ssvagent.exe" a bit of Java code from Sun. I located the exe file and renamed it "ssvagent.exe.old" and all is now well.

it is a client with a new HP. About all that she uses if IE, email, Word, Quicken and something like Picasa
I have no idea if there are any restore points, and I can't imagine that she did something to cause this.

By default, Windows creates restore points systematically, and so does various software when installed so you should have restore points. Read here how to restore your system:Link Removed - Invalid URL
