Multiple BSOD - appears to be from ntoskrnl.exe - help please

[enzyme]

Hi, I have been having a lot of problems with my computer today and yesterday.

Initially my comp would just crash and i would have to power off to reboot. Now im getting BSODs instead, i have tried to work out the cause of these by myself but they all apear to be caused by different problems. I have looked at a lot of other BSOD threads and i have used verifier.exe which created one of the memdumps.

I seem to get them whilst playing games such as lol or fallout or watching youtube videos, but sometimes i have had them for no reason at startup. I have done a fair amount of virus and malware scanning just incase it was somthing like that but its most probably a driver?

i have uploaded the BSOD files,

thanks in advance.

Two issues

1-Dtsoftbus01.sys Driver verified and one of the issues
Please remove any CD visualization programs such as Daemon Tools and Alcohol 120%.

They use a driver, found in your dmp, called sptd.sys, that is notorious for causing BSODs.

Use this SPTD uninstaller DuplexSecure - Downloads DuplexSecure - FAQ

when you're done you can use this Freeware:

MagicISO Virtual CD/DVD-ROM (MagicDisc) in its place

Using MagicISO to create ISO image files

2-Symantec. Caused at least 2 of these.

Symantec is a frequent cause of BSOD's. I would remove and replace it with Microsoft Security Essentials AT LEAST TO TEST

thank you

Hey thanks very much for your help!!!

Ill look into changing my AV then and i have uninstalled sptd.sys, since then i have not had a BSOD so fingers crossed.

Is there anywhere you know of that i can learn to assess BSODs myself?

thanks for your help

There is a fairly steep learning curve but if you just want to diagnose your own there is an app called blue screen view. It isnt accurate 100% of the time and WinDeBuger is much better but it will give you a glimpse into the subject.

If you get serious about learning and have lots of time feel free to pm me.

Hi, thanks very much for you help, since my last post I have had a slight problem, I downloaded bluescreen from nirsoft to have a look at the files which was interesting. I am studying computer forensics at uni next year so I'm always fairly interested.

So I logged on this morning with no problems and did a bit of facebook and stuff, then I ran league of legends and after about 10 minutes I got a bsod and I got a glimpse if 'memory allocation' then my comp turned off and my BIOS settings all got reset, and I reset them and restarted and it crashed on the windows loading screen, now I can power it on but nothing appears on the screen, I have tried a different monitor and u have rebooted countless times. I havnt been able to find a simular problem on the internet.

I know its a bad problem but any ideas? Thanks in advance

We have a good tutorial for such problems: http://www.sevenforums.com/tutorials/219533-troubleshooting-windows-7-failure-boot.html

Let us know if you need help with any steps in the tutorial or if you still need troubleshooting steps after going through the tutorial. As an FYI: step 9. in that tutorial will allow you to backup any important data you have on the system.

Hi,
thank for you link, these steps would be useful if I could get onto the computer a tall, I have reset my cmos and tested my ram, I think my nvidia video card is fryed although I see no possible reason why. I have at the moment taken out my hard drive and have plugged it into another computer and I am backing up my data.

When this is finished I will use bluescreenview to find the dump file for the bsod that killed the comp and post it up. As I am backing up my data I might as well just completely re install win 7 pro whilst I have a second computer. My main concern is why a bsod broke my computer in the first place.

Maybe a virus?

Thanks in advance as any help is good help.

A BSOD can indicate hardware failure, which could subsequently cause the computer to stop working. I missed that the screen is now blank when it starts. Try doing a BIOS hardware/software reset:

1. Shut down and turn off the computer.
2. Unplug the computer from the wall or surge protector (then remove the battery if it is a laptop).
3. "Remove the computer from any port replicator or docking station, disconnect
   cables to printers or devices such as external monitors, USB memory sticks or SD cards, headset or external speakers, mouse or auxiliary keyboard, turn off WIFI and Bluetooth wireless devices." (Use Hard Reset to Resolve Hardware and Software Issues HP Pavilion dv5000 Notebook PC series - HP Customer Care (United States - English))
4. Hold down the power button for 30 seconds. This closes the circuit and ensures all
   power from components is drained to clear the software connections between the BIOS
   and hardware and clear any corruption in the temporary memory.
5. (If it is a laptop, plug the battery back into the laptop and then) Plug the computer back into the wall. Do not reconnect any unnecessary peripherals; monitor, keyboard,
   and mouse should suffice and be the only peripherals reconnected.
6. Turn it on to reinitialize the software connections between the BIOS and hardware

Nope no luck :/ I guess I caught some kind of virus which has led to my mbod malfunctioning. It's a shame as its not that old ( a few years) I'm checking to see if it could be a loose connection but it doesn't look good. thanks for all your help, I do like this forum.

Thank you

Here is the information I give for hardware stripdown:

   Warning

Before you proceed with the following, answer these two questions: Are you still under warranty? Does your warranty allow you to open up the machine to check hardware? If you are unsure of the answers to these questions, contact your system manufacturer. :warn:WARNING: The steps that follow can void your warranty!!!

Strip down your system to run only the bare essentials: one RAM module, the CPU, motherboard, one hard disk, one graphics card (or use onboard graphics if you have it), keyboard, mouse, and one monitor. See how the system behaves. If it is stable, add one piece of hardware back at a time until you get crashes again. Take notes of what hardware you add and how the system responds to the hardware changes.

As you add and remove hardware, follow these steps for ESD safety:

1. Shut down and turn off your computer.
2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.

Once these steps have been followed, it is safe to remove and replace components within your computer.
