ok so i got a new motherboard with cpu (intel extreme i7 DX79SI and a normal i7 cpu), plugged it in and realized my old psu wasnt compatible. got a new psu (600w) plugged it in and started it up, before post the pc powers down. repeat that cycle between 5-10 times to get it running

. started to install my motherboard drivers and had to restart to finish some of it when the "powering down" issue started again...after +-10 tries i got it up BUT something was wrong with my drivers so tried to reinstall them all manually.
still have to switch it on 10 times to start but once i got it going i installed all my other drivers in one go, then again the restart thing...
again after 10 turns i got it going so i tried to install guildwars 2, finishes partly then freezes, cant ctrl+alt+del or alt+tab or alt+f4 or nothing. then when i restart i have to do it ten times again....

save me from my mysery...
(got the i7 mobo and cpu with 8g (1333mhz)ram, ati hd 6870 1gb, sound blaster audigy (old school), 600w new power supply,HAF 932 case, win7 ultimate 64bit)
