I have Lenovo y50-70, is it possible to replace just the video card, as it seems to be broken. And how much would the new one be?

So Lenovo y50-70 (i7 4720HQ, 8GB Ram, Nvidia GTX 960m). Two days ago, when I started it, just gave a bsod after a few minutes. After a few restarts, it remained the same. As the bsod referred to the nvlddmkm.sys, I uninstalled the video card's driver, resulting in frozen screen in a few minutes after starting the computer next times, just like the bsod. So I reseted the Windows with keeping my files, as I could not completely reinstall a new windows, because not at home a the moment. It fixed the freezes, but then I just saw, I'm getting Code:43 (=Windows has stopped this device because it has reported problems) for the Video Card. I have updated the BIOS, and used Display Driver Uninstaller before I reinstalled the driver. Does it mean, that the video card is no longer functional? Or maybe, the complete reinstall with formating the whole hard drive might has some chance to fix the problem? Sorry for the long detail, and Thank you very much in advance!

How to change Shareit deffault storage aside from the two options?

There are two options for you to choose in Shareit android app as default storage. One is from phone storage and another is SD Card which has a very long folder name. Somewhat android>lenovo.anyshare.gps

how can I choose a plain SD Card>Shareit folder instead of that stupid long folder name that even my vlc couldn't detect?

Should I download the same apps into my iPhone 5S?

My Lenovo phone has all the different apps but I want to download messenger, twitter, snapchat onto it and my iphone has YouTube, Facebook and instagram as well as my Lenovo phone. There's instagram, Facebook, messenger, twitter, Snapchat, on my Lenovo phone too. Would it be strange to have the same apps on the two phones itself?

Is my computer gone for good with this hardware issue

It's strange because before I had any problems, it would boot up and run fine, but one day I booted it up, and then I was brought to a blue screen (the "Automatic Repair" screen). For some reason, I can't get past it, and I've tried everything it provides, such as system restore, troubleshooting, etc, but all of these methods would fail.

This is an blue HP Stream 14 I have--runs on Windows 10, and was used for only a few months. This was a computer my sister originally bought for herself for school, but when she bought a better computer, she gave me this one… Basically for free. I did reset everything and made the account on the HP under my name.

But a few months with a computer wasn't that long.

There's no way I can take apart the computer, unless a professional does it--enough that even the battery can't be removed.

I've even done advanced methods, like the CMD fix, but none of that worked.

I do have another computer in mind that I want to get--a Lenovo 100s Notebook. It seems like a pretty decent computer, and the Best Buy selling it just wants $180 for it… Brand new.

But anyways, I could take the HP to a computer store, but my mom doesn't have the time, and I don't have a license (since moving from one state to another).

Do you all else know another way I can try to fix my computer, or am I basically ****** and need a new one?

I have a Lenovo Y700, and whenever I try to play a movie or long video, it will start a slow stutter that renders it unwatchable and silent?

If I'm using the display, there's nothing I can do; I simply have to refresh the page and find where I was. If I'm connected to a monitor or TV, removing the hdmi and then plugging it back in resets it and I can continue, but that's not a sustainable fix, especially when it's still within warranty. I suspect it's an update/software issue, but any troubleshooting help would be very much appreciated
