Blank screen while playing videos

[samb_ch]

Hi,

I have bought and used Biostar hd 5670 card for a few week ago. i got many experience about this card because it always go blank while i try to play the videos like .mp4 .mkv and HD movies. It also on media decoding assesement and watching videos online. This problems blow up after close the player or done watching. I tried a lots of solution like update adobe flash player, update AMD Catalyst to Version 12.10, Test with other motherboard, change PSU+more. Finally it still the same. Or it need to configure a crossfirex to work?. i run out of ideas. It still works well for gaming just video problems. Any one have an idea?.

My system:

OS:Win 7 Ultimate 64bit
Mb:AsRock H77M
CPU:i5 3470
RAM:8gb
GC:1gb Biostar HD 5670(also include gold finger connector on board design)
PSU:600 watt

Note: it work on the old system which spec: Asus p5kpl am-se,intel pentium 4, 1gb ddr2, but when ram upgrade to 2gb the problem back again. i don't understand why?

I'm very thank if my problem solved. Please help...

Do you have onboard video ? If yes disable it.
Get the codecs for .mp4 and .mkv, use different apps. to run the video.

I don't see other onboard graphic display in devices manager just hd 5670 because i made a fresh windows installation to make sure the problem from OS. but it doesn't.
Codec is k-lite codec pack 9.4.0. I used only wmp and mpc, so i gonna try more apps.

Thank for reply.

I always use VLC as it plays almost anything without need for 3rd part codecs. I would not install its browser helpers or whatever they call it, but for files on your system, it works well.

Yes! I feeling OK with VLC Player. It's the best. thank...
One more thing is watching videos online also very good because i used chrome to replace IE(before it also the problems).
What about rating computer. "I still can't rate it". Any other solutions? Will it can't be solved forever?

Thank again...
