I'm trying to get a computer to stay online so it can monitor our calls. The only problem is it doesn't stay online for more then 20 minutes at a time and then it suddenly can't access it. The PC is not wireless, it is connected through an ethernet cable. The PC will tell me it's connected to the internet however it actually isn't. I've run the troubleshooting on the networking page and it says it can't find an issue.
I have done the following:
SCF /Scannow - No issues
Anti virus scan - Clean
Adware clean up - Removed items, no improvement
Junkware removal - Removed items, no improvement
Updated the ethernet card to latest drivers - No improvement
Set up the DNS and IP config to do it automatically - No improvement
Reset the router - No improvement
did a Netsh reset - No improvement
Disabled the tunneling adapters - no improvement so re-enabled.
Did a CHKDSK - Fixed errors but not the internet problem
Ran the repair tool - Fixed errors but not the internet problem.
Now I'm left with very little options. I don't really want to run combo fix if I can avoid it but at this point it's looking like an option. I also note it could be that the operating system might be shot and may have to put to my line manager that I'll need to re-install the OS. Once again something I don't really want to do but I can do it.
Any other ideas on what else I could try? I think I've exhausted all my options at this point and it's been driving me mad for two days!
