trying to install gelid icy rev 2 on radeon 290, the problem im getting is that after the installation the card is not detected in the system. I took it off and installed the reference cooler,the thing is working fine with stock cooler. what could be the problem? the heatsinks for vram and dram are all intact. i've tried to resit cooler on gpu few times,no luck. fans are spinning ok. any advice?
