Hello, so i just got an ASUS P7H55 board with i5-670 CPU, i installed RAM 2x2 1333MHz and tried to Install Windows on Samsung 860 EVO SSD, so i booted up (it was kinda weird at this moment cuz it was so slow and the DRAM led was on for too long and everything was so slow) and somehow i got into the windows 10 install, i started it and in preparing files to installation i got freeze in 3% and I was wondering why, i found plenty of solutions but nothing helped, when i came to something that was new and could possibly help me, the pc was only slow, until then sometimes it was normally fast and sometimes just slow, and i cant get even into BIOS, and if I do i cant use keyboard, i was searching for the memory problem and i found that it could be faulty cpu, so i dismantled it and looked on the pins, on the one was some kinda dirt, so i tried to get it off with screwdiver which wasnt really helping and then cleaned with the tissue and alcohol, everything is the same, is it faulty CPU?
