Blair Technology Group provides only a 90 days warranty for a reason.  I purchased a renewed desktop from Blair through Amazon in July 2019. It all started when the second monitor couldn't be detected by the PC. I had to contact Blair's customer service to find out that I had to uninstall and reinstall certain drivers. After about 3 months I started hearing annoying humming noise coming from the tower (from the hard drive area). Noise became louder over time. I contacted Blair's custom support again. After a week of going back and forth (they kept asking to send them videos), they just told me that my warranty expired, and I should go to a local shop the get my PC checked. They did not even try to suggest some troubleshooting or any help. Do not expect help from this company. Based on my internet research, this sound may be a sign of failing hard drive and I potentially can lose all my data. Please, think twice before you buy anything from Blair Technology Group.
