Found perfect refurb computer for home recording studio. Impressed with box labels stating "Microsoft Authorized Refurbisher" Computer was clean, no loose parts  good so far. Problem #1 following instructions computer would not boot. Display signal lost while fans still running. Unplug, reboot  display comes on repair mode. After it self rebooted went to Microsoft regester page. While entering 3rd page of info the unsmiling face appears we've encountered some problems and are gathering info.. We will reboot your computer.  Screen goes blank, no signal to monitor and it continues to run for an hour in this stage. Unplug, reboot. This time it stays on long enough to regester. I'm checking the windows properties and it gives current date of installation. Then screen freezes and the frown face we've encountered a problem pops up again. After waiting  unplug and plug in, computer won't start. Yellow light flashes on power switch indicating a failed power supply. Looking up to see if Advanced Skyline Tech is regestered with Microsoft based in Canada, I cannot find their name or city in the offical MS page. Look for yourself.
