I've searched online & been unable to find an answer to my problem. I bought my Acer "refurbished" from Walmart & ended up having to buy the thumbdrive to reinstall the OS. Not a big deal considering what I paid for it & had an Acer before & loved it. However, yesterday my moniter would go black for just a second or two, then come back on. I got a message that said, (and this is as close as I can get to it because it goes away so fast), "Display driver Intel HD graphics failed & recovered." I've searched for updated drivers or another solution to this problem & have been unsuccessful. I am running Windows 8.1 with a 500GB hard drive & a 1TB external hard drive, 4GB memory, which I will be increasing to the max of 8GB if I can find a solution to this driver issue. Is it a hardware issue in my CPU or is it my monitor that is the problem? Will appreciate any help I can get!
