Bad_pool_caller BSoD(s)

[Edmachine]

Hello, I'm having some trouble with my PC. It poops out a BSoD every once in a while (up to 4-5 times a day!), and it is really annoying.
The error is, as stated in the title, BAD_POOL_CALLER.
The dump file contains this:

It says something about the symbols. What could it mean? I hope I don't get a BSoD while posting this :P.

Please help, thanks in advance :).


P.S. Operating system: XP

The debug file would point to the Internet portion of the O/S which had fault in it.

tcpip.sys is the system responsible for your internet connectivity.

And you're using XP SP3, there's known problems for SP3 with AMD systems.
Full system configurations would be much more helpful ;)

Gigabyte GA-EP35-DS3
Intel Core2Duo E6850 3.00GHz
2GB of OCZ RAM, DDRII, 800Mhz, Titanium series
Asus 8800GT 512MB (if that's what you meant with system configuration...)
And I have XP Service Pack 3.
Forgot to mention, that I have already tested my memory with MemTest, no errors.
Graphics drivers are updated (CUDA, so I can use F@H). Is there any way to fix this?

EDIT: Actually, the only times when I get BSoD, are when I use the Internet. Sometimes in games, but I use BitComet then... So, there's something wrong with the tcpip.sys?

Hmm, then my initial post suggesting the internet connectivity might had something to do with this is somewhat accurate

Test the theory then. Disconnect from internet, play games, watch movies, benchmark, etc....... and test for bluescreen. If there's none, then we already isolated and identify that the internet connectivity had something to do with it.

If it is, we need to isolate whether its a specific O/S, or driver related problems. Try updating your onboard Realtek 8111B Gigabit Lan driver (DOWNLOAD HERE (ftp://210.51.181.211/cn/nic/PCIE_Install_5698_0725.zip))

Plus update your antivirus and scan your PC for virus or spywares. TCPIP.sys is a viable target since its connected to the internet. :fighty:

I just updated the driver. But, seeing if that was the problem will be hard, because, there are no certain conditions for the BSoD (except, probably, Internet connection). And when, or if, I'll get a BSoD, I'll 'leave the Internet' for a day or two. And, if even then I get a BSoD, I'll post about it here. And the dump.

EDIT: Got a BSoD. Now, I am going to un-plug my Ethernet cable from my PC. And play games, run F@H... browse web with my laptop...
An opportunity to continue writing my website :P.

EDIT2: Haven't got a BSoD so far. Did a benchmark (got ~11000 3DMark06 Points), played some games... nothing happens. Going to plug in the Ethernet cable.

EDIT3: Yup, 15 minutes after plugging in the cable, guess what, it poops out a BSoD... so, I am 95% sure it's the Internet. Did a virus and spyware scan earlier, cleared all the threats. Help?

There is a Discussion on TechSpot (external Link) forum (http://www.techspot.com/vb/topic108142.html). This good chap is having the same problem as yours.

He ended up reverting to SP2, but still the problem persist.

In the end, they suggested that he tested on a different windows partition, and there are no post after that........... which sounds to me that reinstalling windows helps to fix this issues :fighty:

[Edmachine]

I am going to try reverting back to SP2, but can you tell me how to do it? Just download SP2 and install?

Supposedly when you install SP3, windows would keep a uninstall options so that you could remove SP3 and move back to SP2 easily.
This could be found under Control Panel > Add/Remove Program

However, if the SP3 is slipstreamed (integrated into the CD), or you choose not to keep old data (the checkbox for this came out when you install SP3), then there's not way to uninstall SP3 and revert back to previous service packs.

I believe if you re-downloaded SP2, it wont install. :fighty:
