|I'm sorry, I'm not very good with computers, but I'll try my best. My Dell Optiplex SX270 won't turn on after I accidently unplugged it. When I contacted Dell they told me it was either the RAM, the motherboard, or the CPU. Before I go out and spend a bunch of money on any of these parts, I want to know what the problem is for sure. Thanks in advance.|
EDIT 1: I'm pretty sure it's not the PSU because I tried out three different types on it and none of them worked (I actually have two SX270's, and a spare power supply).
