I got a new ACER Aspire all-in-one ZC-700G computer for Christmas. It is so slooow I can hardly stand to use it. It came with Windows 10. I am not impressed. My 12 yr old Dell computer with Windows XP was at least twice as fast as my new computer. Why is this darn thing so slow? What can I do to speed it up? I am using McAfee LiveSafe (for which I had to pay). Virus scans always come back clean. I seldom use the computer (since it is so slow) but when I do, I usually sell things on Ebay or Amazon. I never click on unsafe links or sites. Invariably when I am on Ebay, it takes several seconds (probably 3 or 4) to change screens or to clink on another link. I have to sit and wait constantly. Sometimes, it locks up and gives me some type of script error. Once in awhile, it totally closes ebay and gives me a message that it encountered some type of errer and had to close. I am very frustrated with this new computer. I wish I had my old one back but since Microsoft stopped providing updates for Windows XP, I had to get a new computer. The speed on my new computer has not gotten better (or worse for that matter) since day one. Why is this stupid thing so slow? I'm about ready to just change to Apple. Please help!!
