My lad woke me up this morning complaining that his pc kept restarting. Got around to stripping it all down on the bench (dining room table) and have tried each stick of ram, fitted a standard heatsink rather than his AIO water cooler, tried a different psu and gpu and reset the bios but all with the same result. It will start and then restart 3 times and eventually it gets to the gigabyte bios screen where you can choose to enter the bios, boot menu etc but it won't recognise any keyboard inputs. Dead board? I have tested both of his SSD's and they seem to be fine so lucky he hasn't lost his games etc.
Generally, that sort of restarting is down to failed overclocking but obviously you've reset the BIOS. Is it getting the RAM speed and timings correct?
I have no idea as I can't get into the bios. I've never overclocked anything and it's been working fine for the year we have had it, just went tits up this morning. It has 16gb Corsair 1600 ram in it and a 2500K.
Silly question, have you pulled the cmos battery for a few minutes? as pookie says try a ps2 keyboard too.
Yup pulled the battery and left it out with the psu disconnected for about half an hour. I did think about the ps/2 board but I have a feeling I ditched my last remaining ps2 board.
I don't know if its the same thing (I doubt it) but I tried a ps/2 to usb adaptor and that doesn't work either.
After tinkering some more I think it's a corrupt bios. I still don't have a PS/2 keyboard to try it with though. I have tried to evoke the dual bios thing by doing the holding the power button procedure I found on the net but that hasn't helped either. I'm considering soldering in a new bios chip if they aren't too expensive.

What do I do? 1. Do I risk fitting a new bios chip, something I'm more than capable of doing. 2. Look for a replacement board. (probably expensive for 2nd hand old gear) 3. sell his cpu and ram and go 1151 with something like a 6400/6500.
