I have a htpc which has started playing up. Everything was working fine until one day the drive my os is on failed( broken sata port). I replaced the drive and reloaded win7 32bit and now i can not get picture to my plasma via hdmi from the gpu. If i hook the system to my dell 27" monitor via hdmi all is good. I have tried many things including several different video drivers and changing settings to stop audio being sent over hdmi. I have a Dell studio 1555 (win7 64bit) which has hdmi out and that hooks straight up to the plasma no probs via hdmi. My gear is as follows: CPU- AMD Athlon 64 X2 processor 6000+ (4 years old) MOBO- Gigabyte GA-MA790X-UD4P (2 months old) RAM- Kingston HyperX DDR2-800 (4 years old) GPU- MSI 5670 1GB (3 months old) PSU- Silverstone strider 750 (4 years old) TV - Hauppage HVR 2200 HDD- WD 2tb,1tb,1tb,1tb,750gb and 500gb black (system drive) I have been trying to figure this out for well over a week now. I have tried different gpus (4870, 8600gt), no hdd connected bar the system drive, different cables, plugging the hdmi straight into the tv and bypassing the amp, lowering the resolution, hooking up a monitor and trying to see the plasma as a second screen and clean installs but still no luck. The plasma is no longer recognized on the htpc. I have many other components and everything runs fine through the amp and tv except for the htpc via hdmi. I can get video over vga (dvi-vga adapter), but i was using that port on the tv for a xbox360 and wanted to continue running the htpc through my amp. I dont understand what has happened here. Everything is the same before the hdd failure. I look at the htpc and i just want to put my foot straight through it. Its starting to piss me off I hope someone can shed some light on this situation.
