Jonny Lin, in Blue Screen Error Tags: Windows 7

Blue Screen of Death (BSOD) is a very common issue for Windows 7 users. When a BSOD occurs, your computer displays a bunch of text with a blue background on the screen. It can happen all of a sudden or regularly.

If you are being troubled by this issue, you can try the methods as follows. They can help your Windows 7 computer get out of the annoying BSOD problems.

(Note that the methods 1 to 3 below can only be performed when you can enter your operating system. If you can’t, try the methods 4 to 8.

And in order to use methods 4 to 8, you need to have a Windows 7 installation media, like a DVD or USB drive with Windows 7 installation pack inside. You can create one on your own if you have neither of those.)

1) Run Check Disk

2) Install Updates

3) Update drivers

4) Run Startup Repair 

5) Restore your system

6) Run Memory Diagnostic

7) Fix MBR

8) Reinstall your system

1) Run Check Disk

The BSOD you meet can result from errors on your hard drive. You can run the disk checking tool built in Windows 7 with Command Prompt to fix the errors.

a) Click on Start menu, and type “cmd“. Right-click on CMD in the result and select Run as administrator.

b) Click on Yes when you are prompted. And then Command Prompt will open.

c) Type “chkdsk c: /f” and hit Enter. (This means the system will run a disk check on C drive and fix errors. “C” here stands for C drive, which is usually the system drive for many people. If your system drive is not C drive or you want to check other drives, you can change this letter accordingly.)

d) If the system asks you whether you want to schedule this check to next time the system restarts, type “Y” and hit Enter.

e) Restart your computer to complete the check.

2) Install Updates

The Windows 7 you are using may have some flaws that lead to BSOD issues. You can patch up these flaws by installing updates of Windows 7 provided by Microsoft.

a) Click on Start menu and then on Control Panel.

b) Scroll down and select Windows Update.

3) Update drivers

Device drivers are essential programs operating the devices on your computer. Problematic drivers can usually cause various computer problems, including Blue Screen of Death. Once you come across these problems, it is necessary for you to update drivers on your computer.

Sometimes BSOD problems can be fixed by running Startup Repair. To do this you need to use the Windows 7 installation media you have prepared.
