Problem getting picture via dvi to hdmi

[Bexe]

I have a problem getting picture on my LCD (Sony KDL-40W2000) from the PC (PowerColor Radeon HD 4870 "PCS" 1GB). I use an adapter dvi->hdmi from the PC and a hdmi cord from there to the tv. My computer is fairly new and I built it myself. Have tried possibly every adjust in CCC with no result and of course with the newest driver.

The only time a got a picture on the tv is when the system reboot after installing new ati drivers, I can see picture on the tv until the vista desktop are being loaded and then the tv just blanks end gets no signal.

There are no problem with the tv it works fine and should not be the weekest link. Obviously there must be some problem but dont know what it could be.

I have also update to the latest BIOS version and after that I never had an image on the tv, not even when I install new drivers. CCC shows that the tv is connected and everything but there is just no signal to the tv, its blank.

Could anyone please tip me on what the problem could be?

Greatly thankfull

Have you tried specific resolutions like 1920*1080 (1080p) or 1280*720 (720p). On my 42" LCD TV I have to set the resolution on a normal computer LCD display and then connect it to my TV as it only displays those exact resolutions.

Yes it's set by default

I wonder if anyone know what this BSD stop code means:
0x0000001E(0xFFFFFFFFC0000005,0xFFFFF80001C63B22,0x0000000000000000,0xFFFFFFFFFFFFFFFF)

I dont only have problem with the picture to the tv, but also stability problem. Can these two problems maybe have anything to do with each other? How do a test if the grapic card is guilty one?

Thankfull for any help!
