this is what it shows..in exclamation marks

please fill out the system specs fully. not much we can do to help we hardly have any information

As Cloud said, please provide your system specs. In the meantime, double-click on the first Base System Device. A device properties dialog box should open and give specific information about the device. Open the Driver tab and see if the driver can be updated. Follow the same steps for each of the other two Base System Devices and the Microsoft Virtual WiFi Miniport Adaptor_01.

I got a 64 bit Hp pavilion with 4 gb of ram and 320 gb of hard drive. its original OS was Vista but i have upgrated to Windows 7. Amd turion x2 is my processor.

all the drivers are updated. but the ones with exclamation say that there are no need for update or that it cant find any updates.

yes a exclamation nsign

and then what
