COD4 pbB.exe heartbeats stopped problem

Ok boyz here's the deal.
I still get kicked like every 1,5minutes for the wellknown pbB.exe heartbeats stopped.
Now ive got a trouble ticket up with evenbalance but those mongs are giving me advice a 3year old could.
Standard bla bla answers.
I did every thing i possibly can to try and fix it ( uninstalled/reinstalled both game and pb several times,search modem if it accepted pbA and pbB etc etc)
As a last resort i even did a frikin reformat of my 2nd HD and installed the game on there.
I could play 3 maps yesterdayafternoon but when i started up the game again in the evening i got kicked AGAIN for the same frikin issue.
Tbh im out of ideas now.
On my old sempron 3000+ pc i never had these problems, it started when a friend of mine send me a pc from the USA.
So the only things i can think of that could be the issue is something wrong with the pc itself (mobo/processor)
My GPU and core heat up to about 70 degrees and my 8800GTS heats up so bad that i could bake an egg on it.

I havent played a decent game of cod4 or 5 in like 5 or 6 months and i really want to get this thing sorted, so if any1 would have an idea/solution i would very much appriciate it.

pc specs:
Motherboard: Asus P5N-E SLI
Processor: Intel(R) Pentium(R) D CPU 2.80GHz (2 CPUs)
Memory: 2046MB Corsair RAM
Video Card: NVIDIA GeForce 8800 GTS
