Issue Details
Installed graphics card yesterday and a crucial m4 240 gb SSD. everything seems to be working ok but after some time, normally around 30mins? then can happen again: the screen falshes bright green then changes the colours all to a reddish pinkish colour. If I go up one on the hdmi channel on the tv then back down to the source channel it will go back to normal again. Sometimes it will flash green and then go the reddish colours then flick back blue then go back to the normal colours. I have moved the hdmi cable to a different port, porblem still occurs. Before the graphics card was installed I was using the same tv and hdmi cable in the hdmi port of the built in gma 2000 integrated hd grpahics and there was no problem like this one. settings are same as before 1920x1080 full hd 60hz refresh. there are more options in catalst this time in comparision to the built in one of the prcessor so am unsure if everything here is the same
