The driver disc that was shipped with your system is out of date. For example there are newer versions of: R228446 R270449 R228448 R312650R228501 R260552  You also don't have them in the recommended install order and some crucial ones missing. As soon as you have installed WIndows 7 64 bit from the Dell Reinstalaltion DVD, you should have the following in the following order.  • WSUS Offline Update • R260746 Dell System Software  • R237653 Intel Chipset  • R228482 Realtek Card Reader  • R260552 Intel Video Driver or R228489 ATI Video Driver most likely the Intel one as you have installed the earlier version of it. • R228436 Intel Storage Manager Driver  • R228440 Intel Storage Manager Application • R230994 Marvell 88E80XX 10/100 Ethernet Controller  • R228532 Dell Wireless there are other variants but because you have selected that earlier I will assume you have that card.  • R312650 IDT Audio • R228749 Dell Bluetooth 365 the addition of a bluetooth card was optional and you may not have it.  • R270497 Alps Touchpad • R272666 Dell Quickset  • Dell Support Centre You may also want to bring the BIOs to A14 but be careful when doing this: • 1545_A14  This will give you optimal performance. Since you suffered from a virus attack you should follow the optional step in my wiki which mentions the use of DBAN before reinstallation of Windows. The bottom of my wiki will take you to another wiki I wrote with some recommended free security software which you might find helpful.
