This is a very common problem with any desktop or laptop of any brand, no matter how old or new a computer is. If you encounter this problem, do not panic, Just follow the below steps.
However, the below mentioned solutions are for Hardware issues. For software related issues, please look forward for my next blog.
Scenario 1: When I start my computer, I see no display, no lights. The computer dies on me.
Resolution:
STEP 1: Power Supply: Verify that the monitor has proper power supply and the power cord is firmly attached to your computer. (Issue resolved >Yes) (No> Perform Step2)
STEP 2: Power Drain: - Shut down your computer or turn it off physically and unplug all the power chords from the wall socket and from the computer (remove the battery in case of laptops). Then simply press and hold the power button of the computer for 30-60 seconds. Now, plug in all the power chords and restart your computer. (Issue resolved >Yes) (No> Perform Step No.3)
STEP 3: Bios Default: Sooner you press the power button to start the computer, keep tapping the BIOS KEY of your computer, until you see BIOS SCREEN. (F10 for hp computers). If you see your Bios screen, (for hp computers) click on Yes > Press F9 one time and click on YES again> Press f10 one time and click on YES. This will change the BIOS settings of your computer and restarts on its own.
Generally, all the power related issues are resolved by performing the above troubleshooting steps.
Scenario 2: When I start my computer, I see a blank (black or blue) screen with out any errors or any dots. However, I find the blue lights on the computer turned ON.

STEP 1: Power Drain: - Shut down your computer or turn it off physically and unplug all the power chords from the wall socket and from the computer (remove the battery incase of laptops). Then simply press and hold the power button of the computer for 30-60 seconds. Then plug in all the power chords and restart your computer.
99% of these kinds of issues are resolved by Power Drain. This will not only resolve this issue but also enhance the performance of your computer.
However, if the issue still exists: then perform STEP 2.
STEP 2: Hard Drive Self Test: This would let you know the status of the hard drive of your computer. Shut Down your computer and restart. Sooner you press the power button to restart, keep tapping the BIOS KEY of your computer, until you see BIOS SCREEN. (F10 for hp computers). If you see your Bios screen > select Diagnostics by using the arrow key > select Quick and comprehensive HDD test. Allow the test to run and it will give you a quick result.
If the result says:
FAILED: It means that the hard drive of your computer is gone BAD and needs to be replaced.
PASSED: It means the hard drive of your computer is good. Perform STEP 3.
STEP 3: HARD DRIVE RESEAT:
For laptops: Unplug all the power chords from the laptop. Remove the battery from the laptop. Check for the part which is generally located in the lower right hand side on the bottom panel. This part has an image which resembles 3cds together and has 2 screws on it. Loosen the screws to open the cover. Sooner you open the cover; you’d find a plastic flip attached to the hard drive. Pull the plastic flip gently to pull the hard drive out. Once you take the hard drive out from the panel, Place it back in the similar position as it was placed before. Close the cover and tightened the screws. Put the battery back in and restart the laptop.
For Desktops: Unplug all the power chords from the desktop. Open the tower (computer case) by loosening all the screws. Unplug the cables which connect the hard drive and the computer. Take it out and put it back after some time. Close the cover of the tower and restart the computer.
Hard drive reseat should resolve the issue.
Scenario 3: When I start my computer, I see a blank screen with a white dot in the upper-left corner of the screen.
