Hi i got a Z87-A motherboard, intel pentium G3258, PNY 2x4gb, a raidmax psu, and gtw 550ti. The psu and gpu have been working in my old build. I get no beeps and the CPU LED is lit on boot. I have removed and inspected the CPU and socket to check and im positive the heatsink is on properly. The looming answers i found is there is either a problem with the cpu or the mobo. One thing i found is the CPU isnt supported by the old bios, can i possibly update the bios even with no post and is there a way to do that w/o a thumb drive?
