A stuck pixel is a conspicuous dot of color that fails to change when the neighboring pixels change. Such pixels become very noticeable when the screen turns black.

If the stuck pixels are not as a result of defects in the screen, then JScreenFix can fix the problem. It works by flushing the affected area with hundreds of different colors every minute. This way, it takes only some few minutes to unstick the pixels.

Intel Processor Diagnostic Tool


Of all the components in your computer, processors are the least likely to cause problems. However, they are not immortal and can die just like other components, though it’s usually as a result of an electrical surge or overheating.

Thankfully, the Intel Processor Diagnostic tool can help you fix all issues caused by faulty processors. How does it work?

The tool performs various stress tests on the processor, tests specific processor features, verifies the processors operating efficiency, and checks for brand identification.

The tool then displays the test results. If any of the test results do not meet the standards for operating efficiency, the tool will display the tests that failed and you have to look into getting a new processor.

The tool can be downloaded from Intel’s website. However, make sure to download the right version for your machine, 32 or 64 bit.
