bootloop When Booting on Asrock Z87 Intel Ex

Hello everyone,

Thank you for visiting and being able to read my post, in the middle of the pandemic now I really need this PC for my work. I used motherboard asrock z87 intel extreme4 for my pc and this motherboard has not been used for almost a year.

so last week i got to use this again and i buy procesor i5-4690 got new ssd and hdd, and i used second ram ddr 3 2gbx2 from last pc. I then assemble all the parts to the new case and plug all cable to mobo.I thought that this motherboard was still function, so I immediately turned on the computer after I was able to assemble it. but what??? my pc got bootloop no display ,no signal anything,
I just got pc on for a few seconds and then turned off and turned on again like that.

I've done a little experiment to try to fix this pc,I have made several changes to the PSU that I used, I have done to plug and unplug all cable from instalation, but i didn't get any results, and i dont see any signal from dr debug,


so what i must to do for this, I have plan to get a new ram tomorrow, or you can say that my mobo was broken??


thank you everyone i hope get help from u all
