PC will not connect to the internet all of a sudden

I have a problem with a conflicting device on one of my networks which takes my laptop speed way down. But it doesn't drop out completely. Rayda is helping me troubleshoot it and I've asked her to also look at this when she gets back on.

OMG .. you know what? My laptop lost connection too this morning - the WiFi was connected but there was no connectivity. Then, an hour later, BOTH the laptop AND the PC came back online. Maybe, in spite of the laptop working, this was a fault with the building's WiFi and they've just fixed it (there are no office staff here at weekends, just security). If that is the case I am REALLY sorry to have caused you kind folks to rather waste your time on a wild goose chase like this - although all the information is very useful. The fact that the laptop was fine lead me to believe that the fault was with the PC, not the WiFi system itself. I also did compare the ipconfig results, PC and laptop. The laptop was fine, with all components, DNS etc., as they should be. The PC was, well, as posted.

Well, early days: I have only tried connecting the PC to the internet once, so will report back again later to say whether all is OK. I am going top do a repair ('upgrade') install on the PC anyway, as the boot time is still way too long and red error messages, Event 100, are showing in Event Manager - doing a repair fixed this problem before, (odd though that restoring an image of the C drive made when booting was fine does not fix the problem???).

Will post again later today. Thanks again.

Kind of looked like that to me also because you weren't getting a thing from the router as it was.

The router was working fine for the laptop - not sure what you mean.

Well, I did a repair install, as if from Vista - and this time it made a bit of a mess of my setup. I would have spent a few hours sorting it out, but the booting was still just as slow, so I gave up and reinstalled my C drive image. So I am back to square one now: I can get online OK, but the booting takes way too long. I don't see why the bootlog gives that long list of drivers that don't load. Is that normal? Will try to get a similar log from another Win7 PC to compare.

Did you follow these basic steps? Clean Reinstall - Factory OEM Windows 7

Hi there. No, I dare not do that. I do have the Windows 7 DVD here in Bangkok, but most of my 3rd. party programme installation discs are back in the UK.

Actually, I use the said PC almost exclusively for Microsoft Flight Simulator (for which I also write programmes) and there are a large number of 3rd. party payware addons I have installed with rather complex online verification procedures. A clean install of Windows would create quite a nightmare to be honest, in respect of getting all my programmes authenticated and running again. If there is no other way, I shall just have to live with the lesser annoyance of slow booting.

There must be a way though of fixing this without a clean installation. As I said, the PC booting problem corrected itself a few days back when Firefox & Adobe Flash crashed (possibly coincidental?): if I had known that my internet connection problem came from outside I would have left things as they were. In trying to fix things (reinstating my image file from when all was OK) I have brougfht the slow booting back again. It's quite a mystery to me ...

Work with Cluberti on gathering your trace. I've never known him not to get to the issue as he's the top expert anywhere on this. He's busy now with the latest SysInternals release but PM him and he'll respond.

Thanks for your replies to both threads - I will do that and report back if I find a solution.

Followed (as before) the instructions to the letter. Now I get a BSOD every time I boot! I know that the +DRIVERS part of the string may cause this, but I can't now get back into Windows apart from Safe Mode: blue screen every time. Great! Any ideas how to get back to where I was and try the boot trace again, without the +DRIVERS instruction?

Martin

Later: .. Used startup repair to go back to a system restore point. Now I can boot! This is all getting to be a bit of a nightmare!

Removed the mention +DRIVERS and ran again. Right at the end, after the system reboots and the 5' wait for the trace, I just get an error message. Rather than double post, please see here for screenshot:
