Causes of a Computer Blue Screen
All of a sudden, your laptop screen turns blue and in a desperate move, you restart your computer to get things back to normal, at least for the time being. You may also try to call a technician and spend a fortune trying to get your pc fixed. Unfortunately, restarting the PC doesn't always solve a Bluescreen problem. So what exactly, in the simplest of words, is a blue screen? Moreover, what are the causes of a blue screen? Is there a way to solve this problem with just a few clicks?
A blue screen is simply a precautionary measure that ensures that a PC that runs on Windows OS doesn't get damaged in the event of a kernel mode error of sort. It shuts down the PC and provides you with error message on a blue colored background. With the error information, an IT professional should be able to tell what problems the computer is encountering.
Any attempt to eliminate an identified problem by manually editing the registry should be discouraged, especially if you are not an advanced IT professional. To be on the safe side, don't manually edit the registry. The registry contains important registry keys and DLL files if altered, may cause the PC not to function properly. If you do decide to edit the registry, make sure you make a backup of the registry before editing.
What are the causes of a blue screen? Anything from bad device driver, faulty hardware, or harmful changes made to your system may lead to a blue screen. In addition, the blue screen of death (BSOD), as it's famously called, may occur when you have several applications running on your system. This problem, however, disappears when you stop running the applications. If the blue screen occurred immediately after you finished installing a program, the best thing to do is to go back and uninstall the software.
Another sure remedy is to restore your PC to an earlier point in time using system restore: System restore takes the system back to the last good known condition. System restore leaves your data intact. You may opt to repair your system from booting your computer off the Windows Vista or XP DVD.
If none of these fix the BSOD, it is possible you have a hardware failure. I would first download MemTest86 to see if your memory is faulty. If this finds a problem, you may need to buy new memory. If you need help with this, the following guide on how to buy and install memory may help. If your memory checks out ok, I would download a hard drive health monitor to see if your hard drive is going bad. You may also want to run the Windows Error Checking utility to check for disk errors.
