Windows 8.1 sudden shutdown and repeated restarts

The Iron Rose · Feb 16, 2014

Hi! So uh, I think this is the proper place for this, or at least I hope so. So seemingly randomly, my lenovo y410p will shut down and restart automatically. That is to say, I'll be doing whatever and out of the blue it will completely shut down, making the sound that I'd expect if I just removed the battery. Then after a few seconds it'll turn back on, remain on for anywhere between 5-10 seconds, and then shut down again. It'll keep doing this on and off, occasionally not automatically turning back on, until I'm lucky enough to actually to get it to run and function. Occasionally taking out the battery and using the laptop just on AC power will make it run, but not always, and I'm pretty sure it's just me looking for a solution where there is none. I recently got my computer back from lenovo's service department where they replaced the motherboard, and the problem happened briefly (~2 minutes) but didn't persist for long. I've been using it fine for the past few weeks with no troubles, until I went to sleep with the laptop on and found it off in the morning. Here's the DxDiag just in case: ------------------ System Information ------------------ Time of this report: - Pastebin.com

In an effort to fix it I've tried using two different batteries, both of which I know work perfectly fine. I've tried on battery and on AC power and the problem will persist, which leads me to believe it's not a problem with the power supply. I'm not... really sure what else to do, though I did download a minidump toolbox program that I saw was recommended on another forum. I can't really make heads nor tails of it, all it tells me is that the shutdown was unexpected and I've a problem with my performance library, which is weird since I've no idea what would've caused that. Nor, really, what that has to do with anything. The results file is here: MiniToolBox by Farbar Version: 23-01-2014 Ran by Sara (administrator) on 10-02 - Pastebin.com

In terms of changes, Lenovo did replace the motherboard a few weeks ago, and I recently installed new intel graphics drivers but besides that nada.

My OS is Windows 8.1 64 bit, non-pro version.

In terms of system specs I have the third computer on this list: IdeaPad Y410p High-Performance 14" Multimedia Laptop from Lenovo | Lenovo (US) the 779$ one. However, I have a Nvidia 750M graphics card instead of the 755, and I cloned windows over onto a Samsung 250gb EVO SSD drive. I'm using a caddy for the 1TB HDD mentioned for spare storage space. That means my C drive is a 250GB SSD (I partitioned 20% of the SSD as free space and made sure that it didn't have a drive letter) and my G drive is the included 1TB HDD. I also have 8 GB RAM, and the i7 4700MQ CPU @ 2.40 GHz. Never overclocked nothing and I haven't the faintest how to. Bios version is 74CN35WW(V1.10) and I've updated windows and checked with windows update and all that jazz. I believe my drivers are up to date too. Here's the speccy snapshot: http://speccy.piriform.com/results/ajYIW5aDj7tHFOUyNTBf3kw

I also uploaded a video of what I'm talking about: https://www.youtube.com/watch?v=fWuUZ-yztA4

Crummy quality but I was recording and uploaded it from my phone, so do forgive me.

Unfortunately this is happening several times per day and has been for the past week or so and I'd really appreciate any help in fixing the problem. It's happening semi-randomly, around 3-4 times per day and basically makes using my computer a gamble.
