Please install the GPU drivers and do the GPU test
Run Furmark to test your GPU. Furmark tutorial
Run Furmark for around 30 minutes
Your GPU temperatures will rise quickly while Furmark is running. Keep a keen eye on them and abort the test if temperatures rise too high
Please do the following after furmark:
- Open taskmanager
- Go to the tab startup
- disable everything
- Search msconfig and open it
- Go to the tab services
- Check 'hide microsoft services'
- Uncheck all other services
- Click apply and click ok
- Reboot if asked
This is a clean boot, we need to find out if a program is communicating with the wrong memory.
See if the problem persist, if the problem does not persist enable in the startup tab in taskmanager 1 item and in the services tab in msconfig also 1 service, reboot and see if the problem persist. Keep doing this until you find the culprit or there is nothing left.
