My Laptop turns off after 5 seconds....

Hi Norelle, can you please try the following steps for me:

• Remove the battery
• Disconnect the Power lead
• Press and hold the Power Button for 30 seconds
• Connect the Power lead
• Re-insert the Battery
• Turn your System on

 

After oc, I turn on pc, it turns off and on again.

I oc my I52500k to 4.5ghz at 1.29v and everything is stable, I ran Prime 95 but when I turn on the pc, after about 5 seconds it turns off, then after another 5 seconds it turns on again and its booting normally. This is very strange and I assume it has to do something oc. Anyone experienced this?

 

PC turning off after 10 seconds and then turning back on

I recently moved everything into a new and smaller case, and have been having some issues in doing so.

Basically, when I start up the PC, it boots and then after maybe 10 seconds or so turns back on and stays on. During the first ten seconds and also after, my monitor displays no signal from either GPU.

What is really weird is that to fix this, I tried re-seating my GPU's and re-attaching the cables and this fixed it (as in I was able to access the bios and it did not turn off at all), however, after moving some stuff around inside the case the issue came back (I think I may have bumped the GPU's slightly". This happened a few times, where I would re-seat the gpu's and the issue would resolve temporarily, only to return after fiddling with stuff inside the case. Now, no matter how many times I try to re seat the gpus, the issue persists and while it boots, my monitor doesn't get a signal . All my specs are as listed, except the MB is a gigabyte GA-X99a designare ex.

Additionally:
- The GPU's are seated in the first and second PCI-E lane.
- I think it is unrelated, but when the issue did resolve temporarily, my M.2 ssd would be recognised but I could not boot from it (despite it having windows 10 pro 64 installed when it was on my old motherboard).


The turning on/off makes me think PSU may be the issue, but it doesn't make sense to me why the issue would resolve when I re seated the gpu's if that were the case.

I'd really appreciate any help as I've been trying to figure this out for a few days not and It's really annoying me.
