I have a new PC with the following configuration. any USB device (except mouse and keyboard) is not recognised (e.g. external hard disks, flash memory, iphone, camera, etc.)
Tried several solutions; like changing the usb port, switching off the pc power, updating the windows. Nothing works.
ALso; when I use 3D graphic applications, like imvu, or 3D games (like battle realms) the program starts and runs for sometime; then the pc restarts (it shows the blue screen). My graphics card is nvidia geforce 400 Series GTX 480. The graphics card is 1.0 GB
Intel Core 2 Quad CPU, 4.00 GB RAM (3.00 USABLE), 32-bit operating System windows 7 Home Basic (Genuine). Directx is 11
Any help will be really appreciated.
