System won't boot up past 'starting windows'

[tyreese]

I need some desperate and urgent help. Had no joy trying to fix this for 3 days now. It started initially with my system all of a sudden going into BSOD with nvlddmkm as the error. I attempted safe mode access for a long time and it always froze at classpnp.sys. In the end I managed someone to get into it and used that time to copy my must save file over to my external and decided on a full clean install.

I managed to new a fresh new clean install on my system, everything seemed fine and I back in windows and updating my drivers and updates till I cam across the "updating n nvidia drivers". As it installed the gfx drivers, my screen turn off, which I expected as it made changed to the drivers. But then the monitor didn't turn back on. So I was forced to do a system restart and try again, and it turned off at that stage at which time I left the computer to do it by itself as I went out. 4 hours later still monitor turned off. S once again I restarted the system but this time in safe mode and install the drivers, I reset the system and as it logged on at the "starting Windows's" screen the loop started if it turning off monitor and restarting the system automatically. I could only intervene if I chose safemode.

Now the issue I have is simple. If I install the nvidia drivers, either via nvidia website or windows update, after I restart my system my monitor just turns off and system restarts.

What is wrong with my system. I been trying to to get this sorted for days and I can't find a solution on the Internet anywhere. So I'm hoping the experts here can help as I don't really want to have to send it back to pcspecialist to repair as I need my pc

I have tried various versions of older drivers aswell and still has some problem

As you appear to be able to boot into Safe Mode. Do this and do system restore to a point before the troublesome update of your video driver.
Report back if you get this done OK!
Is this your original PC, the one you were earlier talking about selling?

This might be a stupid question, but are you absolutely certain that you're using the right NVIDIA drivers for your graphics card? I would not trust any drivers delivered by Windows Update. Your problem sounds very much like wrong or corrupted drivers.

 

[mitchell65]

That's what I thought. My idea was to try to get back to a working system, then download the latest driver or even a beta version from the manufaturer and install that. If it goes wrong then he can use the "Driver roll back" to cancel out that update!

i have tried both the windows update drivers, as well as the drivers from nvidia directly ,(320.49) as the latest one and i have tried older version of drivers aswell, the sytem will jsut not boot up with any kind of video drivers installed,

yes its the same pc i was selling previously but then decided to keep it.

and there cant really be anything corrupt as a i did a full clean windows instal and redownloaded the drivers directly from the website

bluescreen viewer gives me
0x00000116 which i googled to mean its something to do with display drivers and its caused by dxgkrnl.sys, which again is video driver related

Yep, that's a video driver error.

I think you have two choices, one is to restore to a point where you had a working system as mitchell65 suggests, the other is to do another clean install (used the custom option and delete the exiting partitions, create new partitions and install into that). Then install all the drivers, generally it's best to start with the chipset driver and I would suggest installing the VGA driver before the NVIDIA driver. Do not install any other software at all at this time. If you still get problems with the NVIDIA driver then I rather think it's likely to be a hardware issue.

If you can still boot in safe mode try uninstalling or disabling the Nvidia driver from device manager,then restart Windows normally and try a clean install of the driver again.

tried all of that already and again, i cant do a system restore as its a fresh instal, drive formatted and started from scratch, tried it once again and blue screens me everytime...

what makes it worse is i just ran over my gold warranty back in april, so even if i get it repaired im no longer covered for parts imma half to cough out even more...

I think you need to call PCS, it does rather sound like a hardware problem now. Sorry.

 

[tyreese]

guess its time for a new system then

 

[mitchell65]

In your first post you said that immediately after the fresh install, everything was fine but it went wrong after the first driver update. Well you sysytem should automatically cretae a system restore point befor it does the update. Are you absolutely sure you have no restore points at all? If it's just your graphics card that is causing problems why not just renew that item. Have you got or can you borrow a spare graphics card from someone that you could try.

 

[vanthus]

I agree that it's most likely a hardware problem,most likely the graphics card,might be worth re-seating the card and maybe clean the contacts.Failing that and although it's probably not a ram issue I would also try one ram stick at time.
mitchell's suggestion to try another graphics card if possible would confirm if it is a faulty card or not,worth a try anyway.

 

[mitchell65]

Might try putting the card in another slot! Don't forget to take the apprpriate anti static precautions before going "inside"!

managed to find a old 8800 gtx, tried it, and it still didnt work, tried all 3 slots didnt work


time to scrap and buy a new 1

 

[mitchell65]

Well I think with what this PC cost in the first place it is worth trying a bit more. There is a faint chance it could be a RAM problem so nothing would be lost in running Memtest from here:

I would run it overnight so that you get at least 10 passes. The more passes the better really!
