I would appreciate a ping to your list of silicone and chip warriors...
Use Craigslist to get a similar vintage Acer laptop.
-Pull the RAM and hard drive (HD) from the laptop. They’ll still be good.
-Swap in the drive and boot up.
-Get to desktop and go through the driver installs, reboots. Your ACER is old enough that Windows will have compatible drivers in the OS.
-Check the RAM on the replacement system if the old RAM is compatible, faster, etc. Add the old RAM to the replacement system. If it’s slower put it in bank 0. If it’s faster put it in bank 1 (slowest RAM goes in lowest bank to set RAM speed).
You shouldn’t lose anything.
