hi all, im running an optiplex 9020 mini tower with 16gb of ram, an i5-4570 cpu, a 1060 6gb gpu and a 1 terabyte SSD. everything was running great until i made the mistake of trying to upgrade the cpu to an i7-4790. i was very careful about static and using a small amount of thermal paste etc, making sure it was seated right. anyway once i had everything connected and tried to boot i got a blinking amber light error, according to dells support site the 2,3 pattern represents a power supply, memory or cpu error. even after switching back to the i5 the error persists... how screwed am i?
