You have Windows 10, right?
Your chipset, graphics, and processor are not supported on Windows 10.
Look way down this page and click on LEGACY INTEL GRAPHIC PRODUCTS.
And look here for your processor:
There is nothing you can do to correct this, except get new or newer hardware that is supported.
Now, if you have an available PCIe x16 slot in that Acer desktop, you may be able to add A COMPATIBLE nvidia or amd graphics card. The focus here is on COMPATIBLE. Some cards are, others not. If you can find such a card, check to see if it is supported on Windows 10. If you are successful, you might squeeze a couple of more years out of this desktop. But, you could also be throwing away money if the desktop dies next month.
One other possible solution is for you to go back to Windows 7.
I know it sounds bad, but that is the reality of hardware that is a decade old.
