While using PC or laptops, we may encounter the problem of blue screen. It becomes bit difficult for a layman to understand the root cause of the same. Often it is confused with a software error, but computer blue screen error is caused by a problem in hardware or hardware driver software. One who knows troubleshooting can handle it or else we can have experts working for us.
Method 1. Diagnosing the Problem
Step 1. Determine if you changed anything recently. The most common cause of the Blue Screen is a recent change in your computer’s settings or hardware.
Sometimes, a poor connection inside the computer can cause a Blue Screen. Open your case and check to make sure that all the cables are firmly connected and that any cards are seated firmly in their sockets.
Overheating can lead to your hardware malfunctioning. One of the most common components to overheat is the graphics card. The second most likely culprit is the CPU.
A common culprit in system crashes is a bad stick of RAM. When RAM fails, it causes the system to become unstable. You can test your RAM by using a program called “memtest86”. This program is available for free online, and is run by burning it to a bootable CD.
Run the “chkdsk” on your hard drive to scan for errors and fix potential problems. A failing hard drive can cause Blue Screens due to corrupted files. To run chkdsk, open Computer/My Computer and right-click the disk that you want to scan. Select Properties.
One way to narrow down what is causing the problem is to remove everything that is not essential for the PC to run. This way, if the error goes away, you know that it was one of the pieces that you disconnected.
Boot into Safe Mode. If Windows won’t start because of Blue Screen errors, try booting into Safe Mode try fixing the problem. As the computer is booting, repeatedly hit the F8 key until the Windows boot menu appears. Select Safe Mode with Networking to boot into a stripped down version of Windows. This will allow you to access your Device Manager, the internet, and other system tools.
Run a virus scan. Sometimes viruses and malware are at the root of a Blue Screen problem. Make sure that you have the latest antivirus software installed, and perform a full system scan to find anything that could be causing problems.
Perform a Repair Installation of Windows. This is a quick alternative to completely reinstalling Windows, as it only copies system files to your computer. This is useful if an essential file has become corrupt and is causing your computer to fail.
Roll back your drivers. If the cause of the problem is hardware, the first thing you should try is rolling back drivers. This process will install an older version of the driver software, potentially getting rid of the conflict.
Roll back Windows updates. If rolling back the driver did not fix the problem, consider restoring to an older, working installation of Windows. This will let you determine if the Windows updates are responsible for your Blue Screen
Clear up hard disk space. If Windows does not have enough space on the disk it is installed on, it can cause system failures. Remove unnecessary files and programs if you have less than 15% of your hard disk free.
Apply new updates and drivers. If rolling back drivers and updates didn’t work, installing the newest versions and updates (if they weren’t installed already) may fix your problem. Check your Windows Update program to see if there are any new system and hardware updates available.
Reinstall Windows. If you cannot track down the error, you can try a full reinstallation of Windows as a way to reset your computer. Make sure that you have all of your important files backed up before doing so, as your hard drive will be formatted for the install process.
Replace faulty hardware. If driver and update rollbacks do not solve your problem, you may need to remove and replace your hardware. Replacing anything other than the RAM or hard drive on a laptop can be difficult and expensive.
