I have just upgraded a 4 year old Dell 1420 inspiron laptop from:
80 gb, Intel T5250 CPU, 2 gb ram, Win Vista basic to 500 gb, Intel T7300 CPU, 4 gb ram and Windows 7 64-bit HP.
Everything works. Windows update knows where to get the driver
. The only drivers
not working are the Sigmatel sound card driver which luckily for me could be loaded from the vista CD. I have found this "Base System Device" under "Other devices" in the device manager and have no clue what it is. I googled online and someone said it was a card reader thing. I saw Windows 7 update the SD card reader drivers under one of its downloads and I can see the "SD host adapters" in the device manager. The creative webcam driver was also updated by win vista.
