I assume you have Samsung Magician installed for your SSD. Please use it and check that it has the latest firmware update, which it most likely does. Also I would like you to run Sea Tools for Dos (
SeaTools for DOS | Seagate) on your Mechanical hard drive. The instructions are in the bottom pard of the link, then you can click the I agree button and download it. Boot from either the ISO file burned to a CD or the USB drive, whichever you decide to use, then run the short and the long tests on the Mechanical drive. Don't run it on the SSD.
After you complete those, please open a elevated command prompt ( click start, type
cmd in the search box,
right click on the cmd entry and select run as administrator) in the black box that opens, copy/paste
sfc /scannow. If you decide to type it, notice the space between the sfc and the /. It is a system file checker which will scan your system files and attempt to correct any missing or corrupt files. What we want are the results to say windows found no integrity violations. If it says files were found but could not be repaired, close the box, reboot and run it again, after opening the administrative command prompt. You may have to reboot and run it three times for it to repair all system files. If it can't repair them after 3 reboots, let us know.
Next I would like you to download the latest driver for your Fire Pro card from AMD and install them using this method :
I am going to give you some links that will help you get a good clean install and not have any drivers you don't need that will conflict with other drivers. Download a WHQL driver from
http://www.sevenforums.com/graphic-cards/329659-latest-amd-catalyst-video-driver-windows-7-a.html . Once you have them downloaded, uninstall you current driver from control panel. next clean up any left over drivers from following this tutorial
http://www.sevenforums.com/tutorials/83814-drivers-clean-left-over-files-after-uninstalling.html and select only ATI Display Drivers. After you have done that and rebooted, install the new driver, only select custom install and install only what you have to. Very few people need most of what they include. You do not need the audio/HDMI drivers as you already have that in your Motherboard drivers. Unless there is some reason you need them, the only thing you really need is the Display Driver.
I would also like you to go into Bios and look at how your ram is set up as far as timings (just the first 4), the frequency and the voltage, it will be called dram voltage. I would like you to look at your Sata controller, which is usually in advanced options and tell me what it is set to, it will either be IDR, AHCI or Raid. While in BIOS please look at the main or monitoring section at voltages and tell me the value of the +12V, +5V and the +3.3V.
If you have any questions at all, do not hesitate to ask. I don't mind answering anything. giving further instructions or explaining why I am asking you to do these things.
