right my internets proper screwed up

the fault it times out

boot up pc, click on ie icon, the page just loads for about 1min, then say s unable to display page? as soon as you click a favorite it pops up ok

then after a bout 5mins, of brousing it hangs, then says unable to display page, click back the page loads instantly, the carry on brousing for 5mins ish then the same crap again!!!

was running ie7, just uninstaled it back to 6, still the same, have pluged my modem dirrectly into the pc now, syill the same.

i dont think its the ntl connection, as ie 6 and 7 run fine on the same conection via my wifi router?
