So I bought this shuttle mini PC running XP sight unseen and it worked for maybe a week or two before it started to get glitchy + eventually just wouldn't turn on at all. At this point if it's plugged in the fan will turn on and if I push the optical drive release button the LED on that will turn on for a moment but nothing else is going on. I have changed the CMOS battery, reset cmos with the jumper, removed + reseated the battery, ram hard drive and optical drive one at a time and POST will still not run. The power LED will briefly flicker sometimes when I push the power button but it does not actually interrupt the CPU fan. I have reached the end of any suggestions I've been able to find online. Could there be a problem with the power button itself? I would appreciate any input anyone has. Thank you
