Longer answer: Honestly, it sounds like most of your system problems are OS related. I'm going to go out on a ledge and guess you're running Windows. Here's the thing about Windows... if you don't care for and maintain it, something that's affectionately referred to as "
bitrot" starts to set in with the operating system. Heck, even caring for Windows only staves it off so long. After three years of various patches, upgrades, possible malware infections, bloatware from Acer, and general higgledy-piggledy, it probably wouldn't hurt to just do a fresh OS reinstall and start anew.
Honestly, that's where you should start. Do a quick integrity check of the hard drive and RAM to ensure both are still ticking along well (use
Ultimate Boot CD for this - at least 5 passes of Memtest86 for RAM integrity, Drive Fitness Test or whatever included manufacturer utility is the most appropriate hard drive diagnostics for the brand of hard drive listed in the OS hardware configuration/BIOS), and if those come up skittles and beer, just back up your important data on an external drive and utilize the restore partition on the system or reinstall media that you should have created when you first got the machine. Acer should have instructions to walk you through the process
here. If you get stuck, I know I'm not the only old IT hand around these parts. Once you roll-back to factory default, update the OS to current, reinstall your necessary software, defrag the hard drive and buy a replacement battery with confidence.
I've seen a lot of perfectly good machines turfed because Windows went wonky from viruses/malware/bitrot/neglect, and I have a feeling this might potentially be one of them. Get your hands dirty with a little self-done tech support, you've got nothing to lose and a whole lot to gain.
