Solved BSOD at Windows 7 boot

[Jerald7]

Upgraded from Vista to Windows 7 32 bit Home Premium 3 months ago, everything has been fine until recently. On bootup, I get a blue screen with vertical lines, then Windows starts loading for a few seconds, then back to blue sceen. I am able to boot up in safe mode with networking, but can't find the problem.

The PC is about 4 years old, original OS was Vista.
HP m7747c, Intel Core 2 6400 2.13 GHz, 4 GB Ram, GeForce 7500LE

Now, I cannot even boot up in safe mode.

Please fill in your system specs:
UPDATE YOUR SEVENFORUMS SYSTEM SPECS


User CP (3rd item in the top menu bar) |

Use Speccy - System Information - Free Download
and/or SIW to gather info for filling in the blanks.

Do me a favor and add the word laptop or desktop to the “system manufacturer” block.

Thank you for looking at this. I added the information that I could find, but cannot use Speccy, since I can no longer boot up in safe mode. When attempting to boot up in safe mode, it loads drivers down to \Windows\system32\drivers\classpnp.sys and hangs up at that point. After several minutes, it goes into reboot, back to the blue screen loop.

Go to another computer which also has win 7 installed and is 32 bit if yours is 32 bit or is 64 bit if yours is 64 bit.

Make a System Repair Disc.

Then follow the procedure given in the link at the top of this post.

All my other computers here are 64 bit. I will have to make a trip to get another 32 bit Windows 7. Will repost as soon as I get that done. Thank you.

I ran the Windows 7 32 bit System Repair disk. Now, when it goes to the boot menu screen (to select safe mode), the entire black screen is covered in zeros. You can barely make out where the boot menu options are, since most of the text on the screen is corrupted, so I still cannot get into safe mode.
I tried something else - I unplugged the OS drive and attempted to boot up just to see if I would still have the corrupt screen covered with zeros with dots in them, and they are still there. So it seems this is caused by hardware rather than from the OS.

Sounds like a winner.

 

[Jerald7]

Any ideas on the best way to determine the hardware cause, if that is in fact what it is? I have already pulled the plug on the optical drives, 2nd hard drive, and removed the ethernet card, all to no avail. Could this be a motherboard issue?

BSOD update

I can finally get back into safe mode. I have removed all cards from the PC except the video card, disconnected both optical drives and the 2nd hard drive - trying to eliminate hardware failure possibilities. But I still have the BSOD. I am now operating in safe mode, and have the latest minidump file. Could someone please take a look at this file, any ideas would be greatly appreciated.
I just noticed from my first post on this thread, that the attachment didn't upload. I am uploading it now.

Screen Shots

Could someone please take a look at these screen shots of my bootup screens. I have never seen a computer do this. Any help would be greatly appreciated. I really need to get this PC back up.
Thank you

Finally Solved

I finally solved my problem, with no help from this forum. It was a defective video card. I went to a lot of trouble to assemble all the PC info for this forum, only to have no one to even take a look at it.
