Internet connection disconnects on downloads / uploads

Hello dear forum members,

One month ago I bought a new computer with a pre-installed Windows 7 Professional package on it. Now, every time I try to download a file or try to upload a file (big or small files, doesn't matter, FTP or browser, doesn't matter), my connection disconnects for like 20 seconds and then recovers. This is what I already tried:

Updating all the drivers for my motherboard, cpu, networkcard you name it..
Updating the BIOS to the latest versions
Plugging in a new PCI network card and using new drivers (disabling the onboard LAN)
Settings for my network card to full / half duplex, tried them all
Disabling 'save power by turning of this device' settings
Resetting the TCP/IP stack

The weird thing is that when I startup my PC in safe mode, the problem doesn't occur! I read on the web about a 'clean boot' (disabling all the services / startup items via msconfig and then reboot) The weird thing is.. on a clean boot with everything disabled the problem still occurs! What could this be? If anyone has any idea this would make my day / weak / year! =)

Mainboard: Gigabyte Z77X-D3H (using onboard LAN) Processor: i5-3570K

With Kind regards, Stan

I made a list of all the active services in safe mode (where all is working fine without disconnects) and a list of all the active services during a clean boot (where disconnects instantly occur on downloads or uploads)

Clean Boot:

Network Connections
Portable Device Enumerator Service
WinHTTP Web proxy Auto-Discovery Service
Windows Media Player Network Sharing Service
Desktop Window Manager
Session Manager
Distributed Link Tracking Client Microsoft
Antimalware Service Plug and Play
PnkBstrA (game service, had the problem without it too)
Power Print
Spooler
Shell Hardware Detection
Superfetch
System Event Notification Service
Themes
Windows Firewall
Windows Image Acquisition (WIA)
Windows Live ID Sign-in Assistant

Safe Mode: - Microsoft Antimalware Service - Network Connections - Plug and Play - Power - SAS Core Service (anti spyware) - Windows Firewall

I tried disabling all services 1 by 1 to check what service is causing these problems. Unfortunately it doesn't make any difference!
