Pc turns on then off but then boots normally

[Magicmike94t]

Hi everyone, I have recently installed a new ssd in my system which is now used as my boot drive but ever since then my pc now does this weird cycle where it powers on and the fans spins ok and suddenly shut off but after 2 or 3 second delay afterwards that it turns back in boots straight into windows. Any help would be appreciated

I'm familiar with this behaviour being normal if power is cut from the motherboard then re-applied or if certain BIOS features (like some CPU settings) at changed the system will fully power off then back on.

 

If you turn the system on. Let it do it's cycle, then at the desktop turn it off and back on again does it repeat the cycle?

Hi thanks your fast reply, it's much appreciated. So if I turn off the system with it still connected to power it will boot up fine, its just the cycle when it has been disconnected from power. I just Don't understand what's causing it because its only started doing it after installing a new m.2 ssd and cloning windows onto it.

Yes that cycle is a power check BECAUSE you disconnected the power.

DON'T, there should be no reason for that. Then the cycle will also not be there anymore!

I meant don't take the power-cable out.

I mean do if you're working on it. But if not just keep it plugged in.

You now know what will happen if you do.

 

Computers are made to be used/powered so they are really good at that.

(And yes they can turn off very well too. )

Oh right thanks for that but when I mean disconnected from power I mean that I turn it off at the wall. the power cable itself is still connected to the power supply.

Computers are meant to continuously receive standby power. If you're killing power to the outlet (via light-switch) or the PSU (via PSU switch) then it's going to power cycle every time you turn it on since the board has to go though a start-up sequence.

 

If you stop turning power off at the light-switch the computer should stop cycling at every power up.

Yeah my pc just booted fine as i turned it on from stand by power. the only thing I'm trying to say is that my pc never used to do this from a cold boot (disconnected from power) and I've had for around 4 years. the power cycling has been a thing since the installation of my new m.2 drive so I'm wondering if there's bios setting that needs to be hanged but I might be wrong.

It possibly could be a BIOS setting but in it's nature you don't really want to cut power from the computer every night. There's no reason to, the power it uses in standby is negligible.

ok thank you for your help. il have a look through the bios and get back to you but il keep my pc in standby mode from now on

Also the strain of the capacitors discharging overnight then being charged super fast is a big load on the power-net and the PSU itself.

If you can avoid, do so!

 

(We're talking capacitors that can keep a PC running for couple secconds even if it uses couple hundred Watts!)

Hi again, thanks again for all your advice and support. since leaving my pc connected to power I haven't experienced any power cycling so il leave like that from now on. i also didn't find any bios setting that could of effect anything so it looks like that was the root of the problem. thanks again

Hi Guys! I've been struggling with the very same issue. It all started after I installed an M.2 SSD drive and messed around with XMP SDRAM settings in BIOS on my Asus Maximus X Hero mobo. After shutdown even without pulling the power cable out, on the next power on my PC would start for 1 second, then shut down, then start again and boot normally. After many attempts I finally manage to pinpoint the problem. This behavior was caused by the following BIOS setting: 

 

APM Configuration -> ErP Ready -> Enable (S4+S5).

 

Once I disabled it (ErP Read -> Disabled), the system would power on normally without 1 sec shutdown.

Hopefully this will help some one.

 

P.S. Enabled fast boot in Windows Power Options does not affect my system.

Hi guys! I’ve been having the same problem lately, i’ve tried multiple things to try to fix it and so far nothing. But yesterday i did a test removing the ram (quad channel) and putting dual channel to see if it stopped, it came back to normal in dual channel but when i tried quad channel again it started doing the same thing, it booted, turned off and after 1-3 seconds it would boot normally again. I’m thinking it might be something to do with windows as well because i’ve had some problems after putting a new m2 with windows on it, but not sure yet! If someone know how to fix this it would help me a lot!

Hi guys  recently i too have been facing this issue . this is severly affecting my boot up time , if anybody knows any fix , please do help!
