If you reinstalled yesterday your Windows 7 Operating System, you surely have a bunch of Windows Updates waiting for you...

If you have the Samsung OEM CD (it happens sometime) you could browse it and pick up the drivers there. There must be the drivers in the "Samsung Recovery Solution" to help you finding the proper ones aswell.

Also you could tell us the exact model of the "Samsung series 7 chronos" you have or you, going to their support site and download the appropriate Samsung drivers for your Graphics and USB 3.0.

You need to install the Chipset drivers first. Do this before installing any other drivers.

the model number is NP700Z5B-S01UB i don't Have the OEM CD anymore the computer is almost 2 years old and iv gone to the Samsung support site that's were i was getting the drivers for everything but no matter where i get the drivers for the graphics card it says no compatible hardware found

On Samsung support site i can see the Chipset (Driver) (ver.9.2.0.1019) and HECI (Driver) (ver.7.0.0.1144)

For a new install pick up the Samsung Chipset drivers first before any upgrade.

Then install the HECI Driver.

You might need aswell to enable the AHCI Driver if not already done: AHCI : Enable in Windows 7 / Vista

Again, install the Intel Rapid Storage (Driver) (ver.10.1.5.1001)
