I just obtained “hero” status and didn't even have to try hard.
Was talking with downstairs neighbor. She begged me to look at her teenage son's computer. He bought all the parts, assembled it himself, but it ain't working. This could easily turn into a cluster fuck but I agreed to look at it. So I'm starring into this tower which looks like a hand grenade went off inside it. But after carefully examining things it appeared that everything was at least assembled, the fans were going, keyboard and mouse lit up, but nothing on the monitor. Further checking I notice that the HDMI to the monitor was plugged into the motherboard port but he had an MSI video card. Ah-ha! Plug it into the video card and bingo...we are into the BIOS. So it at least boots that far. I look at boot menu. Where is your DVD? Don't have one was the answer. How do you plan on the loading the OS? Deer in the headlights. Buy a DVD drive. Next question. Do you have a WIN10 DVD? He was going to use the recovery DVD for his HP laptop. Won't work I said. Buy a copy of WIN10.
So, that's where I left it but he was happy and mom was delighted. He did get an Intel I-5 and a MSI video card but only bought 4G of memory and a 128G SSD. And he plans on gaming. D'OH. Told him you need at least 16G memory and a 512G SSD. And I said if you have any other problems let me know. I have a feeling I will be needed again. But I'm a hero.
