The first step is to determine if the flickering is caused by your computer's hardware, operating system, or an application. The simplest approach to check for flickering is to launch a fundamental Windows software like Control Panel or Task Manager and look for it there. If Task Manager does not flicker, the problem is caused by another software. You can also use System Restore to go back in time and try to identify which change may have caused the problem.
If the problem still exists after running Task Manager or Control Panel for a few minutes, it's likely that it isn't caused by any of these common items. It could be caused by one of your peripheral devices such as your mouse, keyboard, or DVD drive. If you just installed your new hard drive, it could also be the cause.
In most cases, screen flickering is caused by problems with your video driver. Before you install a new driver, it's best to update your video driver first. In some cases, this will fix the problem without needing to download and install a new driver. In other cases, it may require that you upgrade to a newer version of the driver.
To check your video driver version, open the Device Manager. Scroll down to find the Video section. Right-click on the device name under here and select Properties. Click on the Version tab. Make sure that your driver is up to date. If it's not, click on the Update Driver button and follow the instructions provided by Microsoft.

In most cases, screen flickering in Windows 10 is caused by an incompatible software or display driver. Check to see if Task Manager flickers to discover whether a program or driver is causing the issue. Then, based on that data, you'll need to update either the app or the display driver. For example, if Chrome causes the screen to flicker but Firefox doesn't, then it's likely that an extension or add-on in Chrome is the problem. You should try uninstalling any extensions or themes and restarting the browser.

Your PC is flickering due to one of three causes: a faulty display driver, a faulty connection between your PC and your monitor, or a faulty monitor. Here are some measures you may take to address each of these issues.
If your monitor is still under warranty, then you should call out the manufacturer to have this issue resolved. Often times they will provide a replacement part free of charge. If they do not, then you should contact a local computer repair shop and ask them what solution they would recommend. Sometimes, only a new unit will fix this type of problem.
If your monitor is no longer under warranty, then there are several things that you can try to resolve this issue on your own. First, make sure that the monitor is plugged in and connected to your PC properly. If it is, then there could be a problem with either the cable or the video card. You should first try disconnecting one device at a time to see which one causes the problem. If neither one works, then you will need to get help from a professional.
Flickering on the screen in Windows 10 is typically caused by a display driver issue or an unsuitable software. Check to see if Task Manager flickers to discover whether a display driver or program is causing the issue. If it does, try a different version or download from the manufacturer's website.
You should also investigate the refresh rates. It might be creating the flickering if it is too high or too low. This panel also contains a plethora of additional settings that you may experiment with.
Overheating Overheating is a common cause of computer screen flickering. Overheating is more likely to be the cause if it slows down or stops when the computer is dormant or during light chores like word processing. Heating components such as the CPU, GPU, and power supply can cause screens to flicker.
Incorrect Video Settings An incorrect video setting may cause or contribute to screen flickering. For example, an user may set the refresh rate lower than it needs to be for optimal performance. Or, an user may enable V-Sync, which prevents the screen from refreshing itself while the user is moving around the desktop. Either of these settings may cause or contribute to screen flickering.
Incorrect Power Supply Setting A weak power supply may cause your monitor to flicker. This could be due to overheating of the power supply or a bad connection. If you are unsure whether this is the problem, try removing any peripherals that are plugged into the same power source for use with another computer until the problem occurs again. If the problem persists after testing the power supply separately, then it is likely the problem lies within its wiring to other parts of the computer.
Incorrect Monitor Resolution/Mode Your monitor's maximum resolution may be lower than what you believe it to be.
Flicker-free displays are specifically engineered to emit a single continuous light source. A standard monitor changes its brightness by flickering, alternating between periods of high and low brightness. While the user may be unaware of the flicker, it can create a variety of problems, including eye strain.
Warren, The flashing LED may indicate that your display is experiencing power troubles. Check your connections again. If all of them are fine, dismantle your monitor and inspect the power board caps.
