Computer will startup by itself and will sometimes restart instead of shut down

[Hardcorehardy]

For the past few months I have had a reoccurring issue where my computer will randomly power itself on from full shut off. It will also sometimes restart itself when commanded to shut off. My specs are as follows:
1 x Processor Intel® Core™ i5-4690K Processor (4x 3.50GHz/6MB L3 Cache) - Intel Core™ i5-4690K
1 x Motherboard ASRock Z97 Extreme 3 -- 3x PCIe x16, 4x USB 3.0, 2X USB 2.0
1 x Memory 16 GB [8 GB x2] DDR3-2133 G.SKILL Ripjaws X
1 x Video Card EVGA GTX 970 4GB Superclocked - Single Card
1 x Power Supply 700 Watt - Standard - *Free Upgrade to 800W Standard
1 x Processor Cooling Asetek 510LC Liquid CPU Cooling System [SOCKET-1150] - Standard 120mm Fan
1 x Primary Hard Drive 2 TB 7200RPM HARD DRIVE + 120GB Kingston SSD
1 x Data Hard Drive None
1 x 2nd Optical Drive None
1 x Optical Drive 24x Dual Layer DVD±R/±RW + CD-R/RW Drive - Black
1 x Sound Card 3D Premium Surround Sound Onboard
1 x Network Card Onboard LAN Network (Gb or 10/100)
1 x Wireless Network Adapter TRENDnet TEW-805UB 802.11a/b/g/n/ac AC1200 Dual-Band Wireless USB 3.0 Adapter (867Mbps AC + 300Mbps N bands)
Any help would be greatly appreciated!

do you have wake on lan (WOL) set on your router. Can turn your computer on from shutdown just disable the setting. As for it restarting when u shut it down manually it could be your router once again being a dick. I assume you might have set WOL on at some point or a neibor might be playing a prank on you. If you haven't acessed your router before its not hard to find the username/passwords for them and when you do and if the router doesn't allow you in then hit the reset button on the router (can use a paperclip) and then use the default username/password to enter the router and then set your own.

also a quick test would be to disable your internet and try powering down and doing things you normally do when the problem happens. If it doesn't happen and you connect to internet and it does happen its most definitely your router.

I have wol disabled in my bios settings however I didn't know that the router had different settings. Do I just access it the same way as if I was changing the wireless channel on my router? Also this problem happens at random intervals so there is not really a way to test it. At one point it hadn't started itself for about half a month but it has just done it 2 times in the span of two days.

The issue where it fails to shutdown is also a randomly occurring issue and is untestable

My guess would be the power supply or the power/reset button(s) on the case. It could be a WOL thing though, disable internet and see if it still turns itself on.

 

[Hardcorehardy]

Oddly if it gets into this mode where it restarts the only way to fix it is hit the reset button or cut power. Then it will be fine for a while

if you moved it you might have knocked a pin out of place that goes to your motherboards from your power reset/shutoff. So it might just be that you need to make sure all your pins are pushed into place. (might be a full cable instead of pins in which case push cable in but chances are if it was a full cable and not pinned in it wouldn't even work.

in my buffalo router WOL is found in the administration section. To acess my router i need to type 192.168.11.1 in address search bar in my search engine then type in my username/password. The place to change the channels is in wireless section in my router. Best bet is to check if WOL is enabled in Administration section.

I think you have a PSU that is starting to go on you, stuff like this is hard to troubleshoot, i would see if you could borrow a PSU from a friend or something and use it for a week or two. My personal opinion also is 700w PSU is not enough for your machine.

 

[Hardcorehardy]

I actually have an 800w and the whole computer is only about 5 months old

did you check the pins yet?

 

[Hardcorehardy]

I am currently at work. However I recieve an email from tech support saying this: Please turn the power off, clear the CMOS.
Load the BIOS default (press F9 in BIOS).
Disable RTC Alarm Power on in BIOS, Advanced, ACPI Configuration, RTC Alarm power on [Disable]. I will do this as well as inspect all connections later tonight and let you know if I find anything. In the mean time if you have any other ideas I would be happy to try them.

When I got home last night I checked my cables, and everything seemed to be fine. I checked the bios and I had already disabled the setting that I was told to. However I went ahead and did what I was told and cleared the CMOS then disabled the setting again.

 

[Greenpernod]

Way late but in power options if in high performance mode your computer may be in an always on state where if u tap a key or shake the mouse the computer will start again. you can disable this and check through these setting in power options so that your power off button isn't set to restart or sleep mode instead.

For anyone wondering it was a bug and clearing the CMOS seemed to have fixed it.
