BSOD - In need of some assistance please.

Hello, I've been having alot of problems with my PC and as of 2 days ago it started to Blue screen alot while I was in the middle of watching Netflix.

I'm not entirely sure what's going on with it, but it's gotten to the point of where I can't boot safe mode because it starts then stops at classpnp.sys then reboots. Another thing I've noticed is that I can't even get windows to start, it shows up Windows is starting then the screen turns black I hear a beep and it reboots goes through everything until I'm back at the Launch Startup repair & Start Windows Normally.

So really, my problems are as they follow.

1: Cannot boot into Safe Mode (Stops at Classpnp.sys before rebooting)

2: Cannot launch startup repair (Windows is loading files, then blue screens.)

3: Trying to Launch Windows Normally (Starting Windows; black screens I hear a beep and it reboots)

BSOD Messages I've gotten:

Memory_Management *0x0000001A* (While trying to launch Start windows Normally)

STOP: *0x0000007E* (0xFFFFFFFFC0000005) [While Trying to launch Startup Repair]

Bad_Pool_Header *0x00000019, 0x00000000003*

I really hope this was informative enough, hoping it's not something serious everytime I try to start windows normally or anything it just reboots. I can't access the command prompt or anything since I can't even get into the startup screen to login.

I also have Windows 7 64 Bit

Hi Sienna Love and welcome to SevenForums

Run a memory test . Link to tool and instructions below

RAM - Test with Memtest86+

Upload the dmp files . Link and instructions below

Blue Screen of Death (BSOD) Posting Instructions

Read the dmp file tutorial fully

I will work on both of these things, then update the thread when I have them. Only question I have is, would it even be possible to get the dmp file if I can't even get to my login screen to sign into my profile?

Yes but you will need a USB flash drive .

Alright, I have one of those. Would it tell me how to do it via the Tut you linked me?

No it will not .

To grab the dmp files . While the PC is booting up tap on the F8 key on your keyboard . It should then come up to the Advanced Boot Options . Choose Repair Your Computer

Select US as the keyboard language settings, and then click Next.
Select the operating system you want to repair, and then click Next.
Select your user account an click Next.

On the System Recovery Options menu you will get the following options:
Startup Repair

System Restore

Windows Complete PC Restore

Windows Memory Diagnostic Tool

Command Prompt

Select Command Prompt

Inside the command prompt type

notepad.exe

press <ENTER>

When the notepad window opens up . Click on File then Open then navigate to C:\Windows\Minidumps . Then hold down the Control key and click on all of the dmp files inside the folder . Click on Edit then choose Copy or press Ctrl and C . Then go back to Computer . Locate your flash drive right click on it and choose Paste . It then should copy over the dmp files to the USB Flash Drive .

I just attempted to do what you said, I hit F8 and entered on Repair Your Computer. Upon doing so it said Windows is Loading files then a blue screen comes up and it says.

Technical Information:

*** Stop: 0x0000007E (0xFFFFFFFFC0000005, xFFFFF8000C1C1F8C, 0xFFFFF880027B4828, 0XFFFFF880027B4080)

Lets run a memory test first and worry about the dmp files later .

Okay, I'll go check the link for memory test you sent me & put it on a flash and run it. Then report back with what it says.
