- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.

• Run Disk Check with both boxes checked for all HDDs and with Automatically fix file system errors checked for all SSDs. Post back your logs for the checks after finding them using http://www.sevenforums.com/tutorials/96938-check-disk-chkdsk-read-event-viewer-log.html (you may need to search for wininit instead of chkdsk).
  For any drives that do not give the message:
  
  Windows has checked the file system and found no problems​
  run disk check again as above. In other words, if it says:
  
  Windows has made corrections to the file system​
  after running the disk check, run the disk check again.
  
  
• Run all Basic tests with SeaTools: S.M.A.R.T. Check, Short Drive Self Test, Drive Information, Short Generic, and Long Generic. Run the tests for all HDDs.
  SeaTools for Windows
  
  SeaTools for DOS​
  
  
• If you have an SSD, make sure the following are up to date:
  • SSD firmware
  • BIOS Version
  • Chipset Drivers
  • Hard disk controller drivers/SATA drivers
  • If you have a Marvell IDE ATA/ATAPI device, make sure the drivers are up to date from the Intel site or Marvell site and not from your motherboard/vendor support site.
  
  
• Check Windows for corruption. Run http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html up to three times to fix all errors with a restart in between each. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations. Use OPTION THREE of http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html to provide us with the sfcdetails.txt file if errors occur.
  
  
• Download and install Malwarebytes, update it, do not start the free trial, and then run a full scan. Also run a full scan with your antivirus software installed on your system. If you do not have antivirus software installed, see the http://www.sevenforums.com/system-s...-system-security-combination.html#post1732627 for better security steps and scanning tools. Make sure to update the security software before running the full scan.
  
  
• Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).
  
     Warning

  Before you proceed with the following, answer these two questions: Are you still under warranty? Does your warranty allow you to open up the machine to check hardware? If you are unsure of the answers to these questions, contact your system manufacturer. :warn:WARNING: The steps that follow can void your warranty!!!
  
  For Part 3: If You Have Errors: If you swap any memory components, follow these steps for ESD safety:
  1. Shut down and turn off your computer.
  2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
  3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
  4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.
  Once these steps have been followed, it is safe to remove and replace components within your computer.
