I am trying to determine if a friend of mine has a dead mobo or maybe a dead cpu. It was an hp computer with some FOXsomething mobo (I had never heard of, they are cheap I think)... anyway its out of warranty and Best Buy told him the Mobo was dead. He wants to just buy a new board and save the ram and the cpu. ** The board does nothing on startup. No beeps nothing.. Ive taken the ram out, reset jumpers, pulled the cmos...etc and cannot get it to make any sound. The fans come on so their must be power flowing from power source to fan (although I cannot remember right now if the cpu fan plugged right into the power source or the mobo, sry). So figured they were right that the mobo was dead but when we started pulling stuff off the silver stuff between cpu and fan was bone dry... just made me wonder if maybe the cpu burnt up and the mobo might be good and all we need is a cpu.... BUT I kind of thought that if the mobo was good at all, we would get some sort of beeps no matter if the cpu was good or not... IS THIS TRUE? If I can verify that I should still hear some sort of beeps even if the cpu is bad then I will be sure that the mobo is bad and not the cpu.... any help?
Hi, It all depends wether your motherboard has an onboard speaker or LED poster. If it does have an onboard speaker and your getting no beep codes generally a sign of a faulty bios chip/motherboard. The bios will give out error codes for the following faults: CPU,Ram, Graphics card, Power supply unit and in some cases cpu fan. If your motherboard has no speaker or LED poster then it's best to troubleshoot your way through components mentioned above before presuming the motherboard is a fault. Good luck.
