Had my computer in for service technician thought my video card and motherboard maybe shot ended up buying a new computer and monitor. Got it all home decided to try to plug up the old computer with a HDMI cord period ended up working had to do some minor work but it came back to life. I call Micro Center they said bring the computer back I return a computer the next day got 100% return on everything I bought without blinking and I took less than 5 minutes great service
