I try to overclock my old core i5 750. but i think i forgot about the memory.
i tried to reset the BIOS using the jumper and battery but didn't do anything, it just go black and with a "beep...beep....beep..." sound then it shuts down. i even tried to disassemble and reassemble them.
and whenever i turn off the PSU and turn it on again, the PC starts, but still with a black blank scren and beep sounds.
can it be repaired? if not, what's the problem, and if can, pls tell me how.
