Hi guys,

i noticed this forum provides most detailed info on my new motherboard so decided to check if you might help me.

i recently started a new platform
ASRock Extreme 4 Gen3
Intel i5 2500k
Samsung 470 SSD
Nvidia GTX 470
GSKill 2x4GB 10666
windows 7 g4bit professional

components mounted without GTX 470, using internal graphic with as less devices hooked on (no additional usb's). installation lags a bit but completes eventually and then crashes start with BSOD. this happens before and after INF or any other driver is installed. it is not possible to login to windows, system crashes before.

i tried all sata ports (AHCI and IDE), changed cables. cleared CMOS, checked CPU temp (which was 40C).
- then i suspected a problem with SSD and tried Intel 80gb SSD with newest firmware. didnt' help.
- i tried separating RAM kit and test them individually - no problems
- tried updating UEFI - didn't help my problem, moouse got stuck (1.10), reverted to original uefi

at this point you start thinking like me - MBO is corrupt. i return it, get a new one, exactly the same. guess what? it didn't help.

suspecting SSDs might be the problem i try a functional Baracuda SATA HDD. Same problem.

the only thing i didn't replace is CPU which i am now stressing from mini XP console (Hiren's) with Prime95. 4 self-tests 128k passed without errors. I am completely lost and need this system to work. any suggestions?
