Postup řešení

  1. 1 Press Windows key + R, type 'mdsched.exe' and press Enter. Choose 'Restart now and check for problems'. This tests your RAM for errors. If errors are found, replace the faulty RAM module.
  2. 2 Open Command Prompt as administrator (Win+R, type 'cmd', press Ctrl+Shift+Enter). Run 'chkdsk C: /f /r' and press Enter. Schedule the check on restart. This checks your hard drive for errors that could cause instruction corruption.
  3. 3 Update your drivers. Press Windows key + X and select 'Device Manager'. Expand 'Processors', 'System devices', and 'Firmware'. Right-click each and select 'Update driver'. If no updates, check the manufacturer's website for BIOS/UEFI updates.
  4. 4 Check your CPU temperature. Download a tool like Core Temp or HWMonitor. If temperatures exceed 90°C under load, your CPU may be overheating. Clean dust from fans and ensure proper cooling.
  5. 5 If your system is overclocked, reset BIOS to default. Restart and press Del/F2/F12 to enter BIOS. Look for 'Load Optimized Defaults' and save. Overclocking can cause instruction bus errors.
  6. 6 If the problem persists, reseat all hardware components. Power off, unplug, and open the case. Remove and reinsert RAM, CPU (if possible), and expansion cards. Ensure everything is firmly connected.
  7. 7 If all else fails, use System Restore: press Windows key + R, type 'rstrui' and follow the wizard.
