So Today, I went to the store w/ my dad because he wanted to upgrade his CPU and RAM in order to make his computer (custom built) better with production (mostly music related.) We decided to reuse the old fan (standard intel heatsink/fan combo) and so I originally used some Goo Gone to clean off the old thermal paste, and then reapplying newly purchased thermal paste.
I did not update Bios or anything beforehand, and am 95% sure there is no ESD damage to the CPUs or anything, I used one of those alligator clip anti-static bracelets and clamped onto my PSU.
When I was done, the machine booted up and all but there was no display to either of the two monitors that was connected via. DisplayPort. All of the lights and fans were running--Motherboard lights, CPU fan, GPU fan and cooling unit, etc. I tried for, about, 4-5 hours to fix the issue.
Here are the details.
Motherboard: ASUS Prime z270-K
Old CPU and Ram:
Intel i5-7500
2x Ballistix sport 4GB DDR4 Ram Sticks
New CPU and Ram:
Intel i7-7700
2x Ballistix sport 16GB DDR4 Ram Sticks
Tried:
CMOS Reset x2
replacing original CPU
testing RAM sticks one by one and slot by slot (16 total tests with just 1 ram stick)
above but at the same time using On-board gfx instead of graphics card
cleaning and re-applying thermal paste to both old CPU and fan
Observations:
USB Ports don't work (powered on, mobo lights up, phone charging cable does not charge on all back and front USB ports but does charge on USB block)
No POST card or sound beeper thing on mobo or case/chassis
Power supply, Graphics Card, and all RAM work in 2nd computer (can't test CPUs because it's an amd chipset)
Conclusions:
Motherboard is Busted
Does my conclusion sound accurate? Is my best choice now to take it to a technician to fix it? or should I try to borrow a friend's mobo (if available) to test CPUs and then determine from that what is busted?
