Hi,
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.
