Mobo: MS 7869 (a.k.a. TC-605)
PSU: EVGA 550W
The only upgrade here is the PSU and the Case. The stock PSU is 300W so that needed to be upgraded. The case is the "Rosewill Challenger X Gaming ATX".
The PC turns on super quick (less than a second) and then shuts down instantly. At first I thought it was the "HDD LED. POWER SW/RESET SW" plugins, but I found a diagram (here: https://superuser.com/questions/692797/front-panel-pins-not-identified-on-motherboard-acer-rs740dvf)
I did the "Paperclip PSU Test" multiple times (too many to count), and the fan on the PSU did not turn on. I am SURE this is the problem, but is there anything else I could have done wrong here that could be the issue?
I have moved everything back to the old case, and old PSU. I think its my motherboard that is toast? Nothing is working now.
