Sung was very thorough, knowledgeable, and professional when it came to diagnosing an issue with my gaming PC. I was in a middle of writing a very important document report in which I reluctantly had to use my gaming computer, then all of a sudden the primary HDD went into the dreaded 'boot mgr missing'. Not only did it go into boot mgr missing, the computer just went completely dead, meaning that nothing was displaying on my screen as well as no POST beep noise, nor could I get into my BIOS. So I went to the nearest IT guy; brought my heavy gear from home; put it on the platform for Sung to diagnose; lo and behold it was my motherboard. What could have cost me 40 bucks at Microcenter to get the PC diagnosed and multiple hours for me to figure out, Sung did it in less than 15 minutes to the extent that he was able to individually remove each component to determine which one is working expeditiously. Although I was eager to buy a new motherboard, Sung decided to sell his old parts to me for a very reasonable price. Took the stuff home, replaced the parts next day, boot up the computer, reconfigured the BIOS to the point that the boot mgr missing is gone, and BAM! Everything works and completely operational, I even got my document done in time. Highly recommend! read more
