Wow thats one I haven't seen before.
Give this a try, open an elevated command window
start orb > all programs > accessories > right click command prompt and select run as administrator.
Then run this command:
netsh int ip reset c:\resetlog.txt
EDIT: if that doesn't work have a look at this thread and see if it applies to your situation:
No Internet Connection After Boot UP or Wake Up
Welcome to the Windows 7 Support forums,
somthing changed after you installed the new PSU and GFX and I'm guessing that your nic card drivers were corrupted or fried as you only get intermittent service.
Also the issue of incomplete data subjects this troubleshooter to speculate on a resolution. Without knowing if you are connected to a WAN/LAN and if you are using a router please follow this link and select your appropriate driver, attached is a image so you can determine the appropriate link, as always please report back the results in order to mark this issue resolved or if we need to continue trouble shooting.

For review here is the image:
Ok the driver will not install, would a new internet card be a solution?
A new card might work, it depends on whats not working correctly. It's possible you may end up no better off than you are now. You won't know until you try it.
Ok installed new adapter and it is still not working, I still get driver is experiencing issues though, what now?
When you say you installed the new adapter, did you also install the drivers for "that" adapter?
Did this PC come with windows 7 x64 installed? The web site lists Vista x86, but that could be out of date. Also it doesn't list any x64 bit drivers? Did you install 7 x64, and if you did was everything working before you installed the new components? When you installed the new ATI card did you un-install the drivers for the on-board video first and disable it in BIOS? Also, you may want to go into device manager and disable the on-board NIC just to make sure its not interfering with the new one you installed.
The drivers were auto-installed. I installed win 7 x64 on a fresh HD drive 1 week after it came out. I did not install the ati drivers because I did not know how to same answer for the adapter.
Did everything work after installing windows 7? You added the ATI graphics card after that correct, and thats when the trouble started? I just want to nail down the sequence of events and go from there.
Also, when you install the dedicated graphics card you usually have to go into the BIOS and make sure the onboard is disabled and or the primary graphics is set to the add in card.
Also, just about every piece of computer hardware requires a driver (software) for it to function properly. Windows may or may not have one that works. If it doesn't that device won't work. Your NIC should have come with a driver CD. Your video card should have one too. If you run the setup on the disk that came with your NIC it should install the driver. That is if it has a windows 7 64 bit driver. If it doesn't you may out of luck.
