PC starting up and then shutting back down

trebor199327 · 8 Dec 2014 at 18:26

Help please,

As the title suggest's my PC starts up and then after passing the boot menu shuts down again before starting the process again.

The PC will boot in safe mode and runs so this makes me wonder if it's something to do with the amount of load on the system.

PC has an i5 processor and came pre clocked to 4.2 from over clockers three years ago. Never changed any of these settings so it it possible it could be something to do with the clocking?

Any help much appreciated, thanks

Can you system restore to a time you know it worked?

trebor199327 · 8 Dec 2014 at 18:38

Tried however this seems to have no effect, after trying this I re-installed windows and have still had no joy.

Thanks

what motherboard is it

koolpc · 8 Dec 2014 at 18:43

What PSU have you got?

trebor199327 · 8 Dec 2014 at 18:43

Gigabyte ga-z68ap-d3, running 4gb ram with gtx560i gpu

And the PSU is ocz zs series 650w

Maybe a dying PSU. Can you test with another?

trebor199327 · 8 Dec 2014 at 19:05

Not with anything with any real power, closest I have is a 405w

That's fine to test with, assuming it's branded and hasn't been thrashed for years, just don't game with it.

If the psu is dying could he not try booting with minimal parts. No GPU (i5 APU) and only 1 HDD.

If he is booting into safe mode then to me it looks like an OS issue?

Fresh install of windows though.

you installed both intel and nvidia gpu drivers? Take out your gpu out, run from ipgu, uninstall all intel drivers and disable device in device manager. then shut down, reinstall gpu and take it from there?

Even if you haven't installed the intel drivers yourself, windows update might have just done it anyway... :/

I would remove the overclock, GPU/S and any extra drives.

Hard to isolate when you don't have another machine to test but for me personally PSU's loose output power or die completely.

1 thing that springs to mind with though, granted it was a server but it would only boot into safe mode which didn't load the network driver.

Worth a chance to check yours since you boot in safe mode I believe?

I had this problem on my OCUK build (Battlefield Commander I think) from about three years ago. Went on for months and I just lived with it but was a real pain, especially as my boot drive was an SSD. Same PSU as OP and overclocked CPU to 4.2 by OCUK also.

It's fixed now but I don't have an exact solution as I can't remember what I did to fix it (getting old), however, I'm pretty sure it was related to either the OC or power profiles. Anyway, reason for posting is that at least in my experience, with the exact same issue and a similar machine, it was not hardware related at all. I'm sure it can be fixed from the BIOS. I think there may be a thread on here about it.

Sorry to be a bit woolly, but you may be able to save time by not removing/isolating hardware, re-installing Windows etc, 'IF' the problem is the same as mine

Clear your CMOS.
Reinstall of Windows without GPU.
Get drivers up to date & stable.

See if it repeats it's shutting down.
