System freezes - Win7 64 bit - background processes hang

I have struggled for several months with a win7 64-bit Home Premium system that is plagued by background processes hanging. The hanging processes seem network related, i.e. mostly all browsers or email client will at some point hang. In Outlook, the sending will hang. Browsers will completely freeze.

The background process cannot be killed with Process Explorer. Task Manager will not open during the hang/freeze. The PC will not fully shut down and must be hard restarted. Some open programs, i.e. Word, will be unaffected during the freeze.

Background process hanging is often Windows Explorer, but still seems network-related. USB might be buggy (have had 2 BSODs related to USB) but reinstalled drivers etc. Not sure any effect.

This is an Intel DX58S02 system, 12 gig, 2 drives, 2-lan, Nvidea GTX 570 -  New in Nov 2011. never really worked. Motherboard and memory were replaced by the builder. The original motherboard did not boot properly. I think they swapped an identical motherboard without reinstalling OS in Nov. - I don't remember reinstalling all the programs -- but my memory is fuzzy from the PC anguish.

I have followed a long and thorough process of problem isolation and fixes to no avail:

- Clean boot (non-MS services disabled)
- SFC scannow
- SafeMode with networking - inconclusive
- Mem test, chkdsk
- updated all Intel and Nvidea drivers, bios, chipset
- Upgraded network cables, new switch
- Disabled power management
- reinstalled USB hub controllers (got errors and a couple BSODs related to USB)
- Reinstalled Firefox, T-bird, tried Opera, IE
- Disabled lan auto-negotiate
- Disabled conflicting audio device driver
- removed network drive from reconnect at logon
- Switched from Avast to ESET nod32

When I reboot, I get a DHCP lease address event error, but seems to resolve satisfactorily.
Other Event Viewer items: WMI - InstanceModificationEvent; Distributed COM -- these don't seem related, but I am not a tech person.

Next step is to send it back to the assembler and reinstall OS, but do not relish setting up the entire system again -- i.e. the system works well enough to tease me along. Plus, I am not convinced a reinstall will find the issue.

I am happy to send any supporting files if requested.

Have you looked for any firmware updates to the MB?.. seems as if your southbridge bus controller might be having some issues. I would agree a reinstall may not fix anything and if this is your second MB then i would think that maybe the firmware of the BIOS or other controllers might be your issue.

Thanks,

Your poblem should be network-related as the system will freeze if there is no valid ip addreess from the DHCP server when you are browsing the Internet or sending / receiving emails.

What are the brand and model of the NICs?

Thanks for your prompt replies:

- Here are the NICs - Intel 82567LF-2 Gigabit and 82574L Gigabit

The bios and LAN drivers have been updated with Intel downloads. Not sure if there are other steps to take.

Your nics should have no compatbility issues with Windows 7. Have you tried to reseat the NICs?

Besides, run ipconfig /all command and post back the results.

Thanks. My NICs are on-board. Wonder if a slot-based card would make a good test?

Symptoms: Just had the problem again while wheel-scrolling on a blog in IE. The spinning-wait-circle kicked in and as a result, send/receive in Outlook hangs, T-Bird hangs -- Word continues ok. Can't shut down fully without a hard restart.

- Comcast Business Gateway
- SMC Networks (Comcast) modem/router

i would just pop in 2 others (they're cheap) and disable the on-board ones to test

I installed an Intel PCI network adapter and can report success. I have been running all day without having to restart the PC or any serious application hang.

Curious that the onboard NICs would be an issue. Must be a mis-match somewhere, but all of the drivers/bios/etc. are up to date.

I have accepted the solution with a cautionary sense that anything can still happen.

Thanks for your support.
