Computer Won't Turn On

SoAdCrAzY · 28 Sep 2016 at 20:46

I have just moved house and my computer won't turn on now that I've set it up again. I have replaced the kettle plug to check if it's that. It still didn't work. The motherboard is an Asus P8z77-v lx Intel Z77 (Socket 1155).

There is a green light on the motherboard so I assume the motherboard is getting power. I have tried looking but can't find if there's a manual power button on the motherboard in case the case has disconnected.

Thanks.

On this diagram could you please say where the power socket is so I can check that? Thanks.

I've checked everything. To clear the cmos I just remove that circle battery and put it back on? Do I need any tools? Is it easy enough?

Thank you. The manual just says that the highlighted slots only clear the clock though? Is this right?

I have checked all the cables and reset the cmos as said but it still doesn't turn on.

Another problem. I took the pwrsw cable out and in again and it showed a sign of life. Everything came on briefly. Then the DRAM LED light flashed red and the PSU turned off but the rest of the fans stayed on. Do I need to check my RAM? They're in an awkward location. They're underneath my CPU fan. Would I need to reapply thermal paste to the CPU if I was to remove the big fan or justhe unscrew it from the other side of the motherboard? Thanks.

I have tried pushing the memok button but that doesn't help.

I've just taken off a big cpu fan and managed to reseat the ram but the problem still persists.

Thank you. I went through all of them steps and it seems like my motherboard is now faulty.

I don't trust myself installing a new motherboard. I'd rather a professional did it. I need to find someone in the Newham area who can do it and not charge a fortune!

So I've no other option?

So if I was to get someone to replace the motherboard, would I need to reinstall Windows?

It's all working fine now but the fan still turns off on the PSU and the red button still flashes when it turns on.

[EDIT] So, it could be that the PSU doesn't need to go on as it isn't under enough stress but is it normal for the red light to come on?
