I really was hoping I would love this PC.  I am still on the Windows 7 platform and I decided to not upgrade that PC to Win 10 since my existing PC is several years old now. Yes, I knew at the onset that ACER 885 is a "value" level PC.  I liked the specifications and thought it would be a perfect fit for me.  The computer worked for 24 hours.  It was pretty fast and did not appear to have much bloatware.  I didn't like the vertical disk drive, it worked, but I thought it was very flimsy. The major problem is that the ACER 885 - UA92 was unable to boot today.  I contacted ACER support and they were timely and helpful.  I spoke with them on the telephone several times today.  We tried a host of various options/solutions  - resetting, repairing, looking in the BIOS menu etc.  Some repair processes did run for 70% to 90% but the message came up unable to repair.  It could find no "hard drive".  There are many "advanced" recovery options, but none worked.  I have made a note to myself to very quickly create a "repair" or backup diagnostics disk - as perhaps another level of support.ACER indicated they would send me "diagnostics/windows" software on a thumb drive - and that it would take a week or two to receive.  And, I could give it another try when I received their software.  Not sure, if that would even fix the PC,  so I returned the ACER to Amazon today (via UPS) as I could not wait that long.  I was hoping ACER could even send me a link to download the repair software myself (from my Windows 7 PC) and place on a CD or USB drive but they did not wish to do that. Amazon customer service is excellent.  I am trying to not be overly critical here and voice my frustration too harshly - regarding the death of this PC .  Yes, it could have been user error - although I believe i did not nothing to warrant the failure.  I am chalking this up to the PC being a "lemon".  I have had about 10 PC's in my life (yes, I am old now)  I guess this happens sometimes in life. Maybe there were other reasons for failure. In any event, the positive about all of this is the defect was found within 24 hours.  In my situation, I did not want to give ACER another try so I just purchased another PC from another manufacturer.  Life can be frustrating at times and everything is relative, of course.  It's not the end of the world, it's just frustrating.
