Solved BSOD 'Bad Pool Caller' while using Chrome and WMP

[BoomerRoll]

Hi everyone! I have been getting several BSODs for about a month now, about four to five times I think. I'm not sure what kind the older ones were, but the most recent one, I was on Facebook using Chrome while playing songs on WMP, and what I remember from reading the BSOD is 'Bad Pool Caller'. Here's what I got after the restart:

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.2.1.0.768.11
Locale ID: 13321

Additional information about the problem:
BCCode: c2
BCP1: 0000000B
BCP2: AA025D30
BCP3: 581868C0
BCP4: AA026338
OS Version: 6_1_7601
Service Pack: 1_0
Product: 768_1

Files that help describe the problem:
C:\Windows\Minidump\111212-29671-01.dmp
C:\Users\Alyssa\AppData\Local\Temp\WER-83179-0.sysdata.xml

The background programs running were: Synaptics Pointing Device, Toshiba Eco Utility, Realtek PCIe Family Controller, Rainmeter, Toshiba Bulletin Board, Avast, some Java update something, and Action Center. I'm using a Toshiba NB520, with Windows 7 Starter 32-bit.

The earlier BSOD I was not able to read, but I was able to save the problem signature:

I read somewhere that Bad Pool Caller could be caused by hardware defects. There were times when I see horizontal lines flickering on my screen whenever I use the laptop for long periods of time. Is that related to this or something? I also just read one of the threads here that it could be caused by a Daemon Tools, and have just uninstalled it before making the ZIP file.

I'm really bothered by this since the warranty deadline of the laptop I'm using is in a month. Could anyone help me? Thank you so much.

Still no replies? Does this happen often in the seven forums?

Welcome to SevenForums.

I've checked your .dmps and hopefully its nothing related to hardware failure.

Here are some steps based on the errors from the .dmps:

Start with uninstalling Avast! antivirus. It is contributing in your BSOD-s and is often a cause of BSOD-s on some systems.

Use Microsoft Security Essentials at least to test:

Run the System File Checker that scans the of all protected Windows 7 system files and replaces incorrect corrupted, changed/modified, or damaged versions with the correct versions if possible:

Run Disk Check on your hard disk for file system errors and bad sectors on it:

You have way to many items at start-up. Free up the start-up, nothing except the antivirus is usually needed.

Will do as soon as I can. Thank you so much!

You're welcome. Let us know how it went

For monitoring the heat/celsius of the system, use Speccy or HWinfo:

• Speccy - System Information - Free Download
• CPUID - System & hardware benchmark, monitoring, reporting

UPDATES:

1. You said that I should update my Intel drivers so I went to the Intel website and found this: Intel® Driver Update Utility It said that I should contact my computer manufacturer for updating the driver for the graphics media accelerator because technical issues might arise if I did it myself (screenshot in attachments). But I also saw the other link you posted (Windows Drivers | Download & Update Windows Drivers | Easy Driver Pro) which can help me update my Windows drivers. Are the Windows drivers different from the Intel drivers? What do I do about updating/fixing them?

2. I've uninstalled avast by the way, and have MSE running. I actually had them running at the same time before you told me to uninstall avast. I guess that's not a good thing. )

3. I've done the system file checker thing before but it said that there were no problems. However I typed /verify in instead of /scannow so I'm not sure if it makes a difference. I'll try doing it again though.

4. I have yet to do the Disk Checkup and freeing up the start-up. For the latter, I'm thinking of using CCleaner rather than msconfig because it seems easier to use.

5. So far, no BSODs and booting has been noticeably faster since I uninstalled avast. I'll be downloading Speccy after I've done everything you have asked me to do.

AGAIN THANK YOU SO MUCH. Whoever you are, you're definitely better than the computer guy I went to who told me that my computer had to be reformatted, just because I told him about the BSOD pssshhhh.

Thank you for the update and yes, running two antiviruses is not a good thing. They would be rather fighting with each other. Complete the rest of the steps and let us know if the pc is running stable.

Can you please fill in your system specs:
