Hi ante1

Just curious about one thing I saw in your computer specs.

Not sure about this but are all your video display and chipset drivers current.

I noticed you are running an older version of display adapter drivers for your ATI Radeon display adapter. I noticed this in one of your task manager pictures. It may also have something to do with your chipset drivers if they are the incorrect ones. It is possible they may be the incorrect ones or they may be conflicting with others drivers in your computer that may not be up to date.

I would suggest making sure all your drivers in the computer are current and up to date.

Does your computer run okay when LimeWire is not in use/running?
