The short version: Via an adapter, I plugged a 4 pin molex connector into a chassis fan header on my motherboard. Now I cannot boot (powers on but no video output, no post beeps) and the DRAM led is on indicating a memory issue. Bad mobo or bad memory?
ASUS P8Z77-V mobo
Ivy Bridge I5-3570k processor
2x8 kingston hyperX RAM
Seasonic platinum 660W PSU
Corsair 500R chassis
No video card present at this time
When I power on the system it comes on for a couple seconds and goes dead for maybe 5 seconds and then comes back on, almost like it is struggling for power. When I first turned it on with the molex plugged in I got the dreaded electrical smell like I popped a cap or something.
