New Member
Hello have a computer 4 cpu Q6600 core
GA p35 s3g mainboard
ATI4850 series advanced graphic card 512MB
OP system is: Windows Business 64bit with service pack 2

I am having very frequent BSOD while playing games and alsor ecently watching movies!!
i pasted one of the recent minidump file here below.

Can someone tell me how can i realise the reason of that BSOD from this minidump?
what are your suggestions?
i was watching movie while downloading files in the instance of BSOD.... is the virtual and physical memory went too low because of downloads? or what happened?

thanks in advance

Hello and welcome to the forums.
Please read the first post in this sticky thread here How to ask for help with a BSOD problem
Do your best to accumulate the data required.
Run the SF Diagnostic tool (download and right click the executable and choose run as administrator)
Download and run CPUz. Use the Windows snipping tool to gather images from all tabs including all slots populated with memory under the SPD tab.
Likewise RAMMon. Export the html report, put everything into a desktop folder that you've created for this purpose, zip it up and attach it to your next post (right click it and choose send to, compressed (zipped) folder.
It looks like from what you've posted thus far that you have a problem with a Realtek Network Adapater driver (rtlh64.sys) if you can determine that actual Model Name / Number of the card installed you may want to try using this link Realtek to see if there is a driver update available for you adapter.
Good luck

I am using the latest drivers of realtek.... my computer was not able recognize microphone from the front jack of computer so that is why i needed to install realtek drivers extra...normally i was using standart installed drivers from vista installation. I am not sure where exactely began BSODs but clearly after that sound driver updates.

I made screenshots and all necessary files as you requested and i am attaching them to the thread.
I added all minidumps files i got since 4-5 days. Many of them appeared while playing a game, i changed(lowered) graphic options everyday but it still did that BSOD, once it happened while watching a movie and downloading, once it did while using firefox.
a last detail i remembered: I somewhat cleaned the dust in the computer lately, removed RAMS, graphic card cleaned them and reinstalled....i also blowed aid in the case and also in the powersupply and took the dust comes out with a vacuum cleaner, this was not the 1st time i did this....i used plastic gloves to prevent electrical damages to RAMs and others, i also removed and turned the main electrical shalter of the case off before i did these.

i hope this help understanding the problems. Since 2008 i am using this computer with this same vista installation(of course i did some updates) and it never made any problems so far.

Yes it did help some and nice job on the CPUz image, your memory seems to be set properly so we can at least eliminate that for now..
Unfortunately we're still looking at
Rtlh64.sys 9/26/2006
That is a realtek network adapter driver file and is not even close to the latest. Try this link here to update it Realtek
If you don't have or no longer use that adapter then it is possible to clean / remove or rename that driver to prevent it from loading and then we can explicitly remove it from any further diagnostic steps. Just do a search for it (probably in C:\Windows\System32\Drivers folder) and rename the extension (Rtlh64.sys to Rtlh64.OLD) easily reversed if problems arise.

thanks for directions..i am updating the driver of network adapter, i will use the computer a few more days with this new drivers and i will tell you about the results.

thanks again, lets look what will happen ;)

Thanks and keep us posted. Any new BSODs please put them in a folder and zip it up and attach it to your next post.
