Windows Vista How to repair a .sys file

Hey all. I've had a computer with vista now for about 2 months and for the past few weeks I've been getting a reoccurring BSOD (stop code 7f double fault). now while I've tried messing around with hardware and such and i cant seem to find any physical problems. When i try and run windbg i get an error regarding the file bridge.sys, and on my BSOD it also mentions a problem with this driver. This driver has something to do with a MAC Bridge. Now before i go testing my processor I was hoping to see if there is something wrong with this file. Now my question is how can I go about fixing or checking this file. While if necessary to reinstall vista i will I hope to test this file somehow without doing that. Any help is appreciated. I'm running Vista 64-bit home edition. Thanks a lot everyone!

 

yea i understand all of this. i looked up my stop code, and read the double fault info, and i have a basic understanding. after my testing everything seems fine (memory power supply). so now i believe either my processor is damaged or for some reason this driver is causing the problem. I have done all the googling in the world and the only thing I find about this file is that it is a MAC Bridge driver. Now I do have a bridge set up, and I have tried removing that bridge and still no luck. when i run windbg i get this:

Now when I also get the blue screen it also mentions the file bridge.sys. So i feel that my options are now either finding a way to fix this file, or reinstall vista, or last but not least try a new processor which of course is my FINAL option. Thats why I was hoping to possibly find some direction on any way to test or repair this file. I appreciate the help.

 

Why are you going to change the processor? (CPU?) It is a networking file (actually, driver).

From what I can gather, with limited background in the subject, I think it is to create a bridge between two networks. If I am right, an example would be that my motherboard has two Local Area Network (LAN or Ethernet) adapters. One I can set to connect to the internet, the other to run on my home network. They can be seperate or I can "bridge" the two networks so that data can cross between them.

The MAC "address" is an identification system for LAN/Ethernet adapters. Every LAN adapter in the world has is own unique MAC address.

I expect what you have done is made settings in your networking system to make a bridge between two networks. The settings are in Control Panel -> Network and Sharing Center -> Manage Network Connections, right-click on the connections and you will see "Bridge Connection ". I can't how to "unbridge" them. If you can't change the setting, investigate how to delete the connections and remake them (Delete on mine are greyed out). The firewall may be involved.

I don't think you have a big problem, just incorrect network settings.

Here is some information, but it is NOT for Vista:
You receive a "STOP 0x000000D1" error after you create a network bridge on a computer that is running Windows XP

Matt, my reasoning for wanting to change out the processor is usually BSOD is either driver related or hardware related. my psu and memory checks out find, leaving fault on the CPU. now I've checked, all my drivers are up to date. but right now everything seems to be pointing to the bridge.sys file. i have tried removing and deleting my bridged connections with no luck. i disabled all unused internet adapters with no luck. so i am thinking that this file was somehow corrupted. i have found that link you posted before and while it has some information i don't think it applies to me. for one its only for xp and 2nd it is for a stop code d1, I'm getting stop code 7f, and in the link it says the hotfix is specifically only for THAT issue...however i am getting tempted to try it. I'm just trying to find if there is any sort of way to check out this file, and if not I'm going to start backing everything up and reinstalling vista. thanks for the help though i greatly appreciate it.

 

Before formatting there are a few things you can try.

Check in Control Panel -> Programs and Features, for any programs associated with the network/lan/ethernet. You may need to uninstall that as well as resetting or reinstalling the networking connections.

You can try running System File Checker
Some Windows Vista functions may not work, or Windows Vista may stop responding

If you do want to reinstall, when you boot to the Windows DVD (do you have a full or upgrade version?), look for an option to repair the current Windows installation.

You won't be able to run those Windows XP hotfixes, they are not for Vista. That link was only for information about the Bridge.sys file.

i've tried the system file checker with no luck, but i will try it again just for the heck of it. and i do have the full version of windows so i'll try seeing if i can repair it. thanks for the input!
