Hi JCHRIX,
What is the exact OS installed on the system? Did the issue start after installing any updates on the system? Are there any unknown devices in device manager? Are you the only user on the machine?
If the system was working fine earlier, then perform a system restore to restore the machine to an earlier point where it was working fine - http://bit.ly/1JEw2ov
Update the BIOS - http://dell.to/1UsKcB1 and reinstall the chipset drivers from the same link - restart and check if it works. If not, restart the system and press f2 key to enter BIOS - check in BIOS environment if the brightness control works fine.
Download the Intel driver from vendor site - http://intel.ly/1JCFVUE and the AMD driver - CSS - http://bit.ly/1RXcKFr
Uninstall the existing amd driver from device manager - restart and check if the system works fine - if yes, then install the amd driver again. If not, then uninstall the Intel video driver and restart and check in BIOS if it works fine - if yes, then restart and first install the Intel driver, followed by the AMD driver.
Also, write me a private conversation with the service tag and your contact details(Name and Email) for case records,
Keep us updated.
