Hello, This problem is either a power supply or a motherboard. The cheapest way too start is too replace the power supply. If it doesn't fix then isn't worth fixing to replace motherboard.

My computer screen keeps jumping or won't stay up


Your laptop screen refresh rate is low (Hertz). When your screen refresh rate is slow, it will flicker and stutter.

To fix this, right-click your desktop, and go to Personalize.
When you're there, go to "Display Settings" and go to "Advanced Settings", on the "Monitor" tab you'll see the screen refresh rate. Change it to the highest number you see.( min 65-70)

Although the change will shorten your laptop battery life, it will fix the problem. Just keep your charger on until it's fully charged, and it should be good.

Very slow and I keep getting the white screen about restoring active desktop. Then it won't let me restore.


You will need to try reloading the operating system of the computer, this is on the recovery disks you should have made when you first bought the laptop. If you do not have the disks contact the manufacturers support site for details on ordering the recovery disks

My computer screen randomly turned white and won't


Your screen might be going bad. Try plugging an another monitor and see if it works or has the same problem. If the other monitor works, it's definitely your screen is bad. If the other monitor fails and does the same thing, then the video card in the computer is bad.

Why does my monitor have a white screen


First, it could be out of adjustment--turn the brightness and contrast controls up and down to see if it makes a difference.
You could have a bad video card in the computer. Do you have another monitor to try to see if the actual video output is good? This is the easiest way of troubleshooting.
When you start the computer, can you see any white printing on the screen indicating it is booting? Does the problem start once Windows starts? If so, try starting in safe mode. If you can do this, then I'd suspect video driver problems.

Screen goes blank (white), sometimes screen display will get big


You can update graphics driver, if that does not fix the issue check the display on external monitor. If the external monitor works fine you can isolate checking the display in BIOS Setup scree (Restart your computer and keep tapping F10 to getinto BIOS). If the same issue in BIOS, you may have to change display of the unit.
