I've taken the motherboard out of the case, disconnected the hard drive and the dvd drive, removed the network card and removed 2 of my 3 memory sticks.
So all i have on the motherboard is the cpu, heatsink, one 1gb memory stick, and my graphics card. I've attached the power supply to the motherboard, and when I press the power button, the heatsink fan spins, the graphics card fan also spins, and all the LED's on the motherboard turn on.
I've tried cycling the one stick of memory in all the slots, and I've tried this will the other 2 memory sticks as well in case one of them is faulty.
I've also tried resetting the BIOS by taking out the CMOS battery but it makes no difference.
I have a spare PSU and exactly the same thing happens, ruling out the PSU, unless I'm extremely unlucky and I have 2 faulty PSU's.
I've also removed and reapplied the thermal paste just in case it had anything to do with lack of or too much thermal paste overheating the CPU and so refusing to turn on. I think this is unlikely but I wanted to rule it out.
Since my motherboard (XFX X58i) is new, I doubted whether that was the problem but now I think it might actually be a possibility having read tons of people having problems with this exact same board.
So, I think I've narrowed it down to either the motherboard, the memory, or the CPU.
Is there anything in addition you think I should be doing to trouleshoot the problem?
I am receiving my motherboard speaker tomorrow so I hope I can discover the problem with the beep codes....hopefully
I have a funny feeling the CPU is fried, I don't know why I think this, but I have a funny feeling this is so.
