How to Fix Blue Screen Windows 7

The blue screen appears in Windows when a serious error occurs. It is so feared that it is called the blue screen of death . But often it has a fairly simple solution. It is almost always due to a faulty driver or a problem with devices or other hardware. But it can also have other causes.

If you need the files on your disk or are worried about losing them, first try to recover your data from the hard disk . To be able to put them safe. Then try these solutions in the order in which I put them.

Steps

1. Go back to the configuration that worked

Windows will start with the latest driver configuration and system registry that did not give problems. That can solve what caused the failure.

a) Turn off the PC. Read this complete step before doing what I indicated and turn it on again. You will have to press the F8 key   repeatedly until you see a black background screen with the advanced boot options.

Start pressing F8 as soon as you press the power button. Do not wait a second. If the Windows logo appears you will lose the opportunity.

b) Use the arrow keys to choose the boot option with  the last valid / good known configuration . Press  Enter .

2. Recover the previous driver

When the blue screen comes out after updating a device driver, it is almost certain that there is the problem.

a)  Restart the PC in safe mode .

b) Follow the instructions to  recover the previous driver  of the device that is causing the failure. That uninstalls the new driver that gives problems and reinstalls the one that was before (which in principle should work).

3. Restore the system

It can solve errors due to drivers or defective programs

Choose to return to a restore point prior to the installation of the device or program that fails. Or return to a point where everything worked fine.

IMPORTANT:

Can’t you get into the PC because the fault is too serious? See how to  restore the system without entering Windows .

4. Update the drivers

When you are not sure which device is failing, try  downloading all the drivers  and update them.

5. Check the hard drive and RAM

The problems in them are two other common causes of blue screens. Especially those of RAM.

There are good options for correcting disk errors if you do not have a mechanical breakdown. Just use a tool that includes Windows. The  RAM check  will tell you whether or not you need to replace it.

Repair the hard drive.

6. Update your motherboard or motherboard

You may not support the device even if its drivers are appropriate. One possible solution is to  download  updated motherboard drivers .

7. Check that you don’t have a virus

Some may infect the boot sector of the disk and cause blue screen errors or prevent Windows from loading. Use Avira, Avast, AVG, Panda or  Microsoft Security Essentials  if you don’t have any antivirus installed. You all have free versions.

NOTE:
If you cannot get into Windows, follow these steps to  clean viruses when Windows does not work .

8. Update Windows

Use Windows Update to install the latest updates and  service packs  of your Windows. They often correct  bugs  that lead to serious errors.

See how:

Update Windows 7

Update XP:
Go to  Start -> All Programs -> Windows Update

Install what the website asks for. Then use the Custom option   to download both optional and high priority updates.

Update Windows Vista:
Follow the link above in Windows 7. The procedure is very similar.

9. Repair Windows

You will not lose anything on your disk. The process only reinstalls items that have to do with the system.

  • Repair Windows 7 (Startup Repair)
  • Repair Windows XP
  • Repair Windows Vista (in English)

10. Restore the BIOS to factory settings

Improper changes in the BIOS can cause failures. Also have it configured for maximum performance ( overclocking ) if you have that option.

a)  Enter the BIOS .

b)  Change the BIOS parameters . Follow the link and go to the  BIOS Setup section . Show your usual options.

NOTE:

The specific way to load the factory settings (Default) or the overclocking level varies from one BIOS to another.

11. Decrypt the error code

Follow  these instructions .

12. Check the board components

The idea is to make sure everything is well connected. I mean the video and audio cards, RAM module / s, connection cables, etc. Sometimes they loosen and cause a bad electrical contact that causes the error in Windows.


IMPORTANT:
Relocating hardware components involves some risk. If you do it wrong, the remedy may be worse than the disease. Seek help if necessary.

a) ALWAYS unplug the PC from the power BEFORE opening it.

b) Follow these tutorials with images (in English) on how…

Replace the board cards

Replace the RAM modules

Replace the hard drive and device connectors

13. Update the BIOS

Seek the help of an expert or do it with extreme caution. If you run badly you can leave the PC unusable.

a) Discover the  brand and model of your board  and the BIOS version.

b) In the link I include now I tell you not to download the BIOS drivers. But in this case you DO have to. Follow the instructions to update it as indicated by each manufacturer.

Download BIOS updates from your board

14. Beam detective

a) Disconnect all external devices connected to the PC, except the keyboard and monitor.

b) Recognize them ONE BY ONE. If the blue screen appears after doing so you will know that this device is the culprit. Most likely, it has a physical problem or is incompatible with your version of Windows. Check its compatibility or take it to a technical service.

Ideally, you will try to replace the other components of the PC one by one: the video and audio cards, the hard disk, the keyboard, the monitor, the RAM, the CPU or even the motherboard itself. But it is unlikely that you have them all in duplicate.

At this point, the most comprehensive alternative is to take your equipment to a repair service.
