I bought this Acer GX-781 in 2017, and I don't use it much anymore. I haven't turned it on for maybe 6 months and now it has problems booting. It stays with the Acer logo and the loading spinning thing then turns black. Yesterday it had some error messages after while and will report back if I get them again. There has been periods before where it haven't used it much where it has taken several tries or long time to get it to boot correctly. I have tried to open the cabinet and clean it for some dust to no avail. It's installed with 8gb extra RAM and a 1tb SATA, if that's relevant in any way.
Does anyone know what I can do to get the PC up and running again?
