Fix: Acer EI491CUR S Monitor Full Black Screen
The first thing I always recommend doing is resetting your PC/Mac. Pressing the ‘esc’ button at the top right corner of the screen or hitting the power button may work on some machines. If these options don’t work then try pressing both shift keys and tapping the power button at the same time.
Clean out the fans
Some computers have built-in fans for cooling down the processor and hard drive, but sometimes they get clogged with dust. Try cleaning them out with compressed air or a canister vacuum cleaner (be careful not to spray any liquid on the fan). Also make sure to clean behind the motherboard after removing the back cover.
Reinstall the drivers
If none of these solutions work, then go ahead and reinstall the computer’s operating system. You can do this by rebooting the machine while holding the Shift key. Once the BIOS loads, press F12 to enter BIOS configuration mode (you’ll need to know how to use the keyboard to accomplish this). There should be two sections labeled ‘Boot Device’ and ‘Boot Order’. Select the second section, scroll down until you find the option labeled ‘Hard Drive’, and set the priority of the hard drive to ‘High’ instead of ‘Standard’. After saving the changes, exit BIOS and reboot the machine.
Other Options to Fix Black Screen on Acer EI491CUR S
- Replace the GPU
- Repair the problem yourself. Here we go
Replace the GPU
This is not a good idea unless you’re really familiar with computers. You’ll need to take off your case and remove the motherboard, memory chips, CPU/motherboard connectors, cables, and any other components around the GPU. Once everything is removed, you can replace the GPU with a brand-new one. Then reassemble and test the PC again. However, before proceeding, make sure you have some spare parts handy just in case something goes wrong.
Second option: repairing the problem yourself
If your graphics card is damaged, then repair your own. But first, let’s try to solve some problems beforehand. To start, check your BIOS settings. Make sure there isn’t anything set incorrectly (like power saving mode). Also, verify if your system uses secure boot. If yes, then disable it. Finally, do a clean restart and try again.
