1. USB issue. You may need to update the drivers for the USB controllers - find them in the device manager (Control Panel>System>Hardware>Device Manager) and right click on them. If any of the USB ports appear with an exclamation point next to them in the device manager it's indicative of an error, usually a driver issue.
2. Java problem. Once you've downloaded Java, I presume you have gone ahead and installed it as well? Which browser (IE, Firefox etc) are you using when you get this error. Also have you made sure you are downloading the correct version of Java for your OS?
Hope this helps

I recently had a clean upgrade of motherboard and processor done as well as a clean install.
My problems are that two usbs at the front of the tower have stopped working. The flash drive which I use there has gone kaput. I have downloaded Java Runtime Enviroment on several occasions but when I visit a java based website I get the following message. "Windows cannot find the required program". I have made sure to download the same properly but it just won't work. I took off my pop-up blocker to download runtime enviroment.
I do require your assistance to find a solution to these problems.
