In August 2009 i purchased an Acer Aspire one Netbook. The unit came preinstalled with WinXP. I subsequently upgraded to Win7. The Unit has worked well until about 1 week ago. Keyboard is malfuntioning...trackpad doesn't work until i hit the Fn+F7 keys...the screen began stuttering (if that's the right word to use)...upon booting into the system...the unit would boot into "windows Boot Manager"...then i was unable to shut it down properly. Now, when operating the unit i get several loud beeps...10 seconds or so...then a successful boot. I contacted the Acer website with negative results as the warranty has expired. Made a trip to a local PC shop. Verdict...as i suspected...motherboard appears to be on the way out the door. As i understand since it came with WinXP the maker says i probably shouldn't have upraded to Win7 (hmmmm). Worked fine for almost 2 yrs with Win 7. If i purchase another Netbook...doubtful...i'll make sure Win7 is the installed OS. I guess that a have a new paperweight. Any ideas from the gurus?
