Windows 7: Limited access - unidentified network

Whenever i start-up my computer, i get a limited access problem, and it can only get temporarily fixed by putting the computer to sleep and then waking it up. sometimes it'll take two or three attempts to make it work again. after about 20 - 30 minutes the problem comes back again. it also happens 5 minutes after i start playing a game that takes up allot of memory, such as minecraft. this problem started ever since i bought my computer, and i have been doing the same "sleep and wake" trick everyday. ive had this computer for 2 months now, and i have tried so many different solutions, but none of them work. can you please get me a permanent solution to this issue.

Have you contacted your computer's manufacturer? It's brand new, so you get free support.

If you'd like some help here, please fill out your system specs and explain how you have your home network configured.

And add a little more clarification to:
As in, limited access to what?

this is my ipconfig when the internet is working, but when its not working, it has different numbers for the default gateway, subnet mask, and ipv4. i tried manually inputing the working numbers, but when i restarted my computer, it would not work. so i went back automatic, and it worked again.
sibbil - the limited access says, my network security key is incorrect, even though the key is correct.

Have you tried deleting the profile and then recreating it?

what profile?

Go to:

Control Panel > All Control Panel Items > Network and Sharing Center

On the left side of the window, select Manage wireless networks.

Right click on the one that's giving you problems and select delete.

Then re-establish a network connection by clicking on the little network icon in your taskbar (lower right side of your screen). You'll need to enter the password for the network again.

ive done that plenty of times. i have tried so many different things, but none of them work for me.

Do you have another wireless signal around you that may be interfering? Maybe one that's setup in your computer to automatically connect to?

Do a screenshot of ipconfig /all when the connection fails.

Other things:

Wireless driver up to date?

Try uninstalling the wireless device in Device Manager, then rebooting so that it automatically prompts a re-install.

i have a bunch of these random networks that all say connect automatically - http://puu.sh/tGTT - but they only show up in that little network bar, its shown at the "manage wireless networks" location. my driver is up to date, and i already tried that uninstall trick, and it didn't work. here's my ipconfig when its broken, but the ipv4 and gateway don't look different, like i said earlier, because i changed it manually to always stay that way.
