BSOD Windows 7 crashes after being runing for a long time

[pcardoso73]

Hi all,

My windows 7 crashes, usually, when I am not working at the computer but I have it runing. Usually takes more than 1 hour to crash and produce the minidump file.

I have tried to leave it runing during the night with Linux (to exclude hardware faults) and in the morning it was still runing fine.

As I get different codes, I will post here what I got from the SF Diagnostic Tool.

This night I left the computer runing all night with windows 7 and it "Shutdown" without any dump file created.

The laptop in question is a Toshiba A300D-14D.

I hope you can help me.

Best regards,
Pedro

PLease update your wireless driver it seems to be what is causing the problem:

8cd0fcd0  82c3b035[COLOR=Red]*** WARNING: Unable to verify timestamp for RTL8187B.sys
*** ERROR: Module load completed but symbols could not be loaded for RTL8187B.sys[/COLOR]
 RTL8187B+0xb035

Driver Reference Table - RTL8187B.sys

You can update the driver from here: Realtek

Hi,

Thanks a lot for your help.

I have left the computer running for some hours and it crashes (reboots, shuts down - strange this one, generates BSOD).

So the system is still crashing. After the update of the driver, I get less BSOD but the systems reboots or shuts down without any warning. Besides this other BSOD have happened, so I will attach a new file from SF Diagnostic Tool.

Strangely it doesn't crash when I am using the pc. Please note that I have disabled all power control functions, so it won't sleep/hybernate/hdd power off when I am not using it.

Best regards,
Pedro

OK the crash you are getting is a 0x7A:

GetPointerFromAddress: unable to read from 831a9830
Probably caused by : memory_corruption

Followup: memory_corruption
---------

Causes: Memory, Paging file corruption, File system, Hard drive, Cabling, Virus infection, Improperly seated cards, BIOS, Bad motherboard, Missing Service Pack

We can eliminates atleast one of these because I can see you are not missing Service pack 1, so please do the following:

Run memtest86+ for at least 8 passes (do this over night it can take a long time):

RAM - Test with Memtest86+

Run these programs to check for virus infection:

Windows Defender Offline
Tdsskiller

Run the system file checker:

SFC.EXE /SCANNOW
Go to Start and type in "cmd.exe" (without the quotes)
At the top of the search box, right click on the cmd.exe and select "Run as adminstrator"
In the black window that opens, type "SFC.EXE /SCANNOW" (without the quotes) and press Enter.
Let the program run and post back what it says when it's done.

Then from the same command prompt run this command:

chkdsk /f /r

Check for a failing hard drive by following this tutorial:

Hard Drive Diagnostic Procedure

Hi DsPrague,

Thanks for your time helping me.
After 8 passes of the Mestest86 no errors found.
The checkdisk took like an 1 hour or more, I suppose something has been repaired.
I ran, as well, Malwarebytes Anti-Malware and it found 13 threats, which were deleted.
The computer seemed to be more stable, but I have had new restarts again and a new dump was generated. Attached please find the zip file from SF Diagnostic Tool.

Just one thing more, when running Linux I can leave the computer by itself for one day or more and it doesn't crash. So I believe it is not an hardware related problem, but a software one.

Thanks a lot.
Best regards,
Pedro

Have you run TDSSkiller?

Scan your system with the following:

• Kaspersky TDSSKiller How to remove malware belonging to the family Rootkit.Win32.TDSS (aka Tidserv, TDSServ, Alureon)

• ESET online scanner One-time virus scanner free with ESET online scanner

• Run Windows Defender as well. How to Use Windows Defender Offline

Heat:
- only use the laptop on a hard surface - with nothing blocking any of the vents.
- use a laptop cooling pad if possible
- blow out all vents with canned air (DO NOT use a vacuum cleaner or an air compressor, they can damage the components).
- ensure that the fan comes on and is blowing air out of the vent (may not happen at startup, but should happen after using it for a while).

For monitoring heat of the system, use Speccy or HWMonitor:

• Speccy System Information
• HWMonitor

• Post a screen shot using Crystal Disk Info: CrystalDiskInfo Standard Edition
• How to Upload and Post a Screenshot and File in Seven Forums

Make a hard drive test from the hard drive manufacturers website:

• Hard Drive Diagnostic Procedure

---

• Use the System File Checker tool (SFC.exe) to determine which file is causing the issue, and then replace the file.

To do this, follow these steps:

• Open an elevated command prompt. To do this, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow. Use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7
• At the command prompt, type the following command, and then press ENTER: sfc /scannow
• The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions. http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html

Hi all,

After doing the Hardrive Diagnostic the system never booted again. I tried several ways to restore the system with the Windows 7 boot cd, but the partition was no longer recognized.

I used a Ubuntu Live CD, and Gparted claimed, at least 81 bad sectors. I ran as, well, 'badsectors' software from linux and within 9% of the disk, I had already 461 read errors.

I would like to know, if I can reinstall the windows 7 using the restoring points ? Where are these files stored ?

My idea is to use the Windows 7 partition from block 206848 to block 44301611 (no errors here). This partition will have only the system itself, and I will create a data partition in other location of the hdd with no errors. The part of the hdd with errors will be unallocated. What do you think ?

Please don't forget to let me know if, when installing seven is possible to recover something from the restore points.

Thanks a lot,
Pedro

I asked for some help on this part, I don't really know much about how you would go about doing that so I will see if some one else does.

The bad sectors will just get larger over time, you need to rescue your files and data using a Linux LiveCD, and then get a replacement hard-drive.

 

[essenbe]

I agree with X BlueRobot. The bad sectors are a warning of hard drive failure. My best advice is to recover your files and replace the hard drive. As BlueRobot says, you can copy the files using a live Linux CD, or http://www.sevenforums.com/tutorials/93347-copy-paste-windows-recovery-console.html. Either method will work as long as the drive is readable. I don't know of any way to pick and choose which sectors to install Windows. But, even if you could, your hard drive is fixing to fail, so it would do little good.
