Please describe one of the most challenging tasks you have had in university. how did you overcomeit

I always wanted to build my own computer。I read a lot of passages and magazines for prepare.When I was sophomore,I got the 5000RMB as computer budget.After I brought all of the computer accessories,I couldn't only stick the CPU,video card and memory chips into motherboard.I could connect them with wires.That was really unexpectable.
I read the passages from the internet again and again and found nothing to help.Finally,I called one of my friends who should know someone to handle it.She called her friend who is good at computer stuff.Then he comes to my domitary.He checked and said he doesn't good at 3A platform.We had to carry the computer accessories to his friend's place.His friend is a real master.He cleaned the awful mess in twenty minutes.
