Windows 7: "Default Gateway is not available", Nothing seems to be helping.

27 Aug 2012   #1

Windows Home Premium 32bit
"Default Gateway is not available", Nothing seems to be helping.

I've purchased a new desktop computer and every time that I go to run multiple programs at one my internet crashes. So I troubleshoot and it resets the Connection for me and the message pops up "Default Gateway is not available: Fixed", after this my internet is back up until I go to run multiple programs again and I keep needing to repeat this progress. It's really annoying and stops me from Skyping with people, Playing games, watching videos and downloading files.
I know some of you will probably re-direct me to some other posts that people with the same problem started and try to find a solution there.. but trust me - I did and nothing seems to be working.
It's not my router because I unplugged my router completely and hooked up my modem directly to my PC and I still had the problem.
I contacted my ISP and there's nothing they could do over the phone.
I did a clean boot, no effect.
I turned off my Anti-virus, firewall, everything to see if it would change, no effect.
I went to CMD did ipconfig /renew and all that, no effect.
I went to IPv4 on my connection and manually typed in The IP, Subnet mask, and default gateway, no effect.
I reset my modem and router multiple times, no effect.
I updated my motherboard drives (Intel Desktop boards) and Graphics card Drivers (Asus Geforce GT430), no effect.
I probably tried other methods too but can't remember..
I'm starting to lose hope and just bring my computer in to memory express for them to look at it, but before I spend my money I wanted to create an account here and give it a shot.
Sorry for the tons of information, but I just wanted to get it clear that I've tried plenty of methods and nothings helped so I don't see the same answer in this post.. although I have seen the word "DHCP" word around which I have no idea what it is but after giving the thing some research, could be.. useful information?

in problems like this you will have to grab a laptop from a friend and check if the problem still occurs.

IF YES THEN change your ISP modem.

A) change your computer network card OR maybe find older drivers.
B) maybe it is a window issue, like we had a virus once that did similar problem,
try running combofix. ComboFix Download
C) if all false maybe move to windows 7 64bit - as drivers are completely different.
End If.

Good luck
