Welcome to the forums
By all means follow the advice offered by Bay Wolf, but the "base system device driver" is usually the media card reader - specifically
And drivers for the media card reader are not included with the chipset drivers. They have to be downloaded/installed separately.
If it's a 32bit version of Windows 7 HP you've installed, the Vista 32bit drivers provided by Dell *might* work?
If it's a 64bit version of Windows 7 - or the Vista 32bit drivers don't work - then you'll just have to try and source suitable drivers elsewhere I'm afraid.
That's the chance you take if/when you decide to upgrade to Windows 7, and Dell don't provide Windows 7 drivers.
From experience, I've found that: “Beauty is in the eye of the beer-holder”!!
