Help me find the short making my build unusable randomly

6 years ago, you guys helped me pick my first build, and most beloved build ever. The build is as follows:

ASRock Z87 Extreme4 LGA 1150 Intel Z87
Intel Core i5-3570K Ivy Bridge
G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBXL
SeaSonic M12II 620 Bronze 620W
Cooler Master CM 690 II Advanced


I have added 3.5 drives, 2.5 SSD drives, Led Lights, EVO 212 cooler, Bluray drive, and fans, all being used for years with no hardware or software issues until very recently.

I get a code 55 as faulty RAM connection, and also code 00, as not enough power to the CPU.


I have bought a brand new PSU at first, and it seemed to have fixed the problem for a while, but code 55 came again, then code 00 again.

I have bought new set of RAM sticks, and placed them correctly on either a1 b1 slots, or a2 b2 for dual channel... it seems one of the sticks was bad, but now with the new RAM sticks the problems came again.


Basically, sometimes the computer will power on weak, as in, only some of the fans spin slowly, but no post. Sometimes it will start normally if I short it to clear CMOS, or if I hold the internal power button for a while to "release a charge built up somewhere"?


I have tried these things because I've experienced, or have seen them before:

*Removing cooler, and looking for bent pins just in case, but no bent pins found.

*Remove EVO 212 cooler, and reinstall EVO 212 cooler just in case the screws were so tight that they were bending the board itself, and damaging the RAM slots.

* Check if the EXACT model of my ram was in the compatibility list Asrock publishes, and my exact RAM model is not technically in that list, but don't know if it's a big issue since I used them for years.

* Bought new PSU to no avail.

*Tried running the computer with the bare peripherals just in case in order to find faulty hardware including bad RAM sticks.

*Tried different RAM slots, or only one just in case the slots themselves were bad, also bought new RAM to no avail.

*Checked for popped capacitors, or unusual looks in the motherboard itself to no avail.



I'm not sure what else to do in order to find the problem, so any suggestions are appreciated.

Could it be a bad CMOS battery itself? I doubt it, but don't know how to test for it either, unless I buy a new one, or learn how to test the battery with a multimeter if possible.
