Network controller trouble. HELP!

Hi, I am having a strange problem with my Realtek onboard (Asus P8Z77-V LX) network controller. I am connected to the internet but I can not access the internet or I have very slow speed. I have reinstalled every driver version I was able to find, original driver from the CD included, I reset the browsers(IE & Chrome), I rebooted and reset router (Virgin Super Hub 1 @ 120mb), I refreshed DNS and Gateway( switched from automatic to manual and vice-versa), I installed a separate network card TP-LINK TG-3468 Realtek Gigabit but got the same behavior (I disabled the on-board while using it), I paused the Kaspersky 2014 anti-virus for a while and still nothing. I scanned with anti-virus for malware & co and nothing was found. My laptop or phone, both connected wirelessly, works like a charm. I really don't know what is going on. Reinstalling my windows 7 ultimate 64bit might look as a final attempt to solve the problem. HELP !

The laptop works well wirelessly but I haven't try it through the wire, I will check this too. I have replaced the Ethernet cable too and switched between all 4 router ports available, still no improvement. I have scanned it with Kaspersky Internet Security 2014, it came out clean. I am very careful with all the wires and I did checked all of them, everything seems to be fine. I forgot to mention that my system is overclocked, not by me, but by the company who sold me the motherboard+CPU+RAM bundle. I tried to enter the bios these days but I wasn't able too (del or F2 and no reaction) so probably is from there.

I tried the laptop with the wired connection and it worked just fine. Only the desktop is having the internet problem and even if a restart it is working for max half an hour and then stops. But still showing is connected

Problem solved...I think

...I uninstall the Kaspersky Internet Security 2014 and the internet start working. Strange because I paused it once without result but after uninstalling everything came back to normal. I wrote to the Kaspersky Technical Support for a solution to this problem and I will post their response when I will get one.
