Can you explain the 'Fix' for ram? T hope you downloaded the ram test from the link I provided. I need you to run that test. There is no fix for ram errors.
On the sfc scan, did you reboot between running it again? If it still says it found errors, reboot and run it again. You need to do that 3 or 4 times until hopefully it says it found no errors.
Updating the drivers, you have to uninstall the old one's first, and do as the tutorial says. If you did it like the tutorial says, there are no drivers when you go to install.
We ask you to run certain tests for a reason, and give complete instructions. If you don't understand something, just ask. We will do our best to explain it further.
Please don't use the Windows memory diagnostic test, it is not very good. Run it this way and only this way.
Please Run Memtest86+
Information
Please download from this site only
http://www.memtest.org/ in the middle of the page are the Download links, you can download the ISO.zip or the Auto USB Flash Drive installer.zip
Extract the Zip file. If you chose the ISO image, burn it to a CD using Windows Disk Image Burner or any Image burner you may have. If you downloaded the Auto USB installer, extract it, insert your USB 2.0 Flash Drive and take note of the drive letter. Run the installer, select the Flash Drive Letter, check the format box and press next. It will install memtest86+ to a flash drive. You can use either V4.20 or V5.01. Boot from your selected media. If you use V5.01 it will tell you to press certain buttons at the start, please press no buttons. The test will begin on it's own and continue to run until you stop it. It needs to run for 8 complete passes or until you receive an error. If you receive an error, stop the test. Even 1 error is a fail. Each pass tests a different part of the ram and each of the 10 tests in each pass tests something different. It takes a minimum of 8 passes to completely test the ram, more passes are better. It is quite a long test and will take several hours depending on how much ram you have. Due to the time length it is best to run overnight. If you have any questions, please do not hesitate to ask
