Hi, I'm having an odd issue here and am hoping to find some help.
My PC is working fine, I reinstalled Windows two months ago. Yet around a month after I started having a strange issue with it. If I shut down the PC overnight and try to turn it on the next day, I have to flip the PSU switch off and on again for it to start. This doesn't happen if I shut down and then turn it on again in a shorter time, like an hour later.

I first initially fixed this problem by clearing the CMOS/updating the BIOS. I can't say for sure which one fixed it as I did both at the same time. Yet, around two weeks ago, the problem has returned. I noticed that after returning from a week holiday, that I had to flip the switch to turn on my PC when I returned (I had the PC unplugged from the socket during this time). In the last few days I have to flip the PSU switch to turn it on every morning after I've shut down for the night.

The PC works perfectly once it is on so I'm quite confused as to what's causing this. Is it possible that a fault in my house's electric circuit is causing this, as the house is quite old?. The PSU is less than a year old. Any help would be appreciated.

Specs:
Windows 7 64 bit
8GB DDR3 RAM
GTX 770
Corsair CX750W
120GB SSD and 3TB HDD
MSI G43/Z87 MOBO
i5 4570 3.20ghz

What you said about CMOS battery is partially right one.

1) Try to chage CMOS battery and see whether the problem persists
2) Try to change your power supply cable connecting from power slot and check it with another one to make sure it is good.

Thank you, I have ordered a new CMOS battery and a new cable and will report back once they have arrived.
