While there make sure that you also have the latest chipset, BIOS, display, network, bluetooth, HID touch, USB and all other drivers, compared to the ones presently installed in Device Manager reached by right clicking the Start button.
Feel free to ask back any questions. Based on detailed results you post back I will have other suggestions if necessary.
