iPod shuffle misbehaving, with very weird symptoms

Ok folks, I know it is kinda dumb to ask something about such an obsolete device, but until now it has been working impeccably... until a certain sad moment when my favorite Ipod shuffle second gen failed me :(

SO what are the symptoms? First of all, it did not play any music. Several earpods have been tested by me, none of them work. The sound of plugged earpods (like you know, the white noise you hear when no music is playing but ipod is on) also did not appear. The light indicators behave very randomly. When I press some buttons and try resetting the device they light up, usually the green light blinks quite randomly. When Ipod is connected to the computer, it is also blinking. But aside from that, nothing happens. When I am 'switching the songs', it does not react. Neither do the volume buttons work.

iTunes won't see it, either. I tried fixing the bugs following all the advice from the official apple website, but it was futile effort. Indeed, the driver for Apple Mobile Device, or whatver, was having an exclamation point next to it, indicating a problem, but after all the attempts to fix the faulty driver I have simply given up. Apparently installing iTunes on a different computer with a connected iPod failed altogether because the freaking iPod is messing with the computer. I really love it, and it has served me for long 6 years. I took a good care of it and I would like to use it just a little longer :( Please help if you know how to
