BSOD at boot, stop 0x00000050

[Baullino]

Hi,
Since a few days ago when I start up my laptop, I recieve a BSOD at the windows loading screen. It happened a few times in the past, and system repair dealt with it easily. But now, all my system restore points are gone, system repair doesn't help and I don't know what to do. The only thing I can do is F8 and F12 at boot. When I try to go into safe mode, the laptop whirrs really loudly, and restarts.

It's not my picture, but it's the same error.
STOP: 0x00000050 (0xFFFFF880009AA000,0X0000000000000000,0XFFFFF800032766FA,0X0000000000000000)

Thanks in advance

A stop 0x50 is a memory error. That means either the physical RAM is causing issues or any driver is passing bad info to the RAM.

Do two things. First and foremost, make it sure that your RAM is healthy. Test your RAM modules for possible errors.

How to Test and Diagnose RAM Issues with Memtest86+
​

Run memtest86+ for at least 8 consecutive passes.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there. Report us at this point, no need to go for the next part of this post.

If RAM is free from errors, Try to boot in Safe Mode. If the computer boots in Safe Mode, execute the Blue Screen of Death (BSOD) Posting Instructions and attach the data with your reply post.

If Safe mode does not work, too, let us know. We will try to explore other ways to troubleshoot the issue.

Thanks for Your reply
After the first pass, an error immediately came up. What should I do now?
@edit right now I'm just going to follow the tutorial

Now follow the "Part 3: If You Have Errors:" of How to Test and Diagnose RAM Issues with Memtest86+

Errors/red lines means one or more RAM is faulty. But the fault may occur due to a faulty DIMM slot, too, which is a motherboard component. Using memtest86+, you can discriminate between a faulty RAM and a faulty motherboard.

How? Say you have two RAM sticks and two DIMM slots. You obtained errors at the test with all RAM sticks installed. Now, remove all the sticks but one. Test it in all the available slots, one by one. Continue the same procedure for all the available sticks.
How to make the inference that is it a RAM issue or it is a motherboard issue? Suppose you have got the result like that:

test|Slot1|Slot2
RAM1| Error | Error
RAM2|Good|Good

It is a RAM, a bad RAM.

But if you have got a result like that:

test|Slot1|Slot2
RAM1| Error |Good
RAM2| Error |Good

It is a motherboard issue. The particular slot is bad.

If it is a bad RAM, you need to change the RAM. Take the other existing (good) RAM to the shop and get one of the exactly same specification. The best is, get a totally new RAM KIT.

If it is a bad slot, it is a motherboard issue. But changing the motherboard needs a preparation for most of us; so dont populate that slot for the time being.

Apparently a RAM stick is broken, thanks
When I try to boot without the broken stick, I still get a BSOD, shouldn't it work?

Can you let us know the memtest86+ results, stickwise and slotwise?

 

[Baullino]

Stick #1 - error at both slots
Stick #2 - no errors

 

[Baullino]

Well, shit. I just connected both sticks separately to another laptop and it worked just fine.
I hope it's not the motherboard though, it seems odd for both slots to break simultaneously. What else can I do?

 

[Arc]

Stick #1 - error at both slots
Stick #2 - no errors

Run the computer with that stick 2 only, till you get a new KIT.

Report us for any further BSOD.

The broken stick works on other laptops, and my laptop gets a BSOD with every stick I have

Then it is your motherboard.

Generally laptops have OEM licenses which are tagged with the motherboard. So changing motherboards may cause licensing issue. Better you take it to Lenovo, ask them to change the board without expiring your OEM license.
