Driver Error on Startup Make Startup Time Longer

If you have a long startup time, try checking the Event Viewer. There are cases about driver error on startup that makes the startup time to become longer than usual.

You can view the Event Viewer on Control Panel->Administrator Tools-> Event Viewer and if you found some faulty driver, try uninstalling the driver that you think might be the cause for the long startup time.

Another solution is you can use the System Restore Point to go back where your startup time is normal and if you've done everything but the result is still the same, then your solution might be to reinstall the OS.

However, reformatting your hard disk and reinstalling a new OS is the last solution and if it's possible, try to solve your problem without reformatting your hard disk.
