GPU not displaying anything

[vpavlicevic]

So for my TV gaiming i use my old pc with Intel Pentium E6500 and i put a new graphics card in it about 4 months ago the Nvidia GT 740. All was fine until i went to my living room and tried to turn it on,  it makes all usual sounds and all fans spin but my TV doesn't receive any signal. I have tried to use another cable and also to use it on my monitor but it didn't work. Do you have any idea what I can do about it?

I have had a similar problem before when using a tv as a monitor. In my case the Bios couldn't display, but when the OS booted it displayed normally. Try unplugging your graphics card and booting using the onboard graphics, then rebooting using the graphics card. It worked for me. 

Good luck

What screen, what connection? You have TV on correct port? Is the GPU working?

I left PC running for about 2 hours to see if that would help but it didn't. And also its an old computer so it doesn't have the integrated graphics. Anyway thanks for help.

It was all working fine yesterday, TV uses HDMI and i tried different cable and on my monitor i used DVI and HDMI. Graphic card seems to work, fan is spinning.

Do any connections on the GPU work with your monitor, or is it only HDMI not working?

I'd echo the "try something other than HDMI" suggestions unless that's what you meant by "tried to use another cable"; It's the first thing to check at this point before moving onto anything else. Does that old 775 board have onboard graphics by any chance? Or could you use the old GPU to test?

[vpavlicevic]

Sorry for that I wasn't active on the forum, at the end I found old motherboard that supports 775 chips and tried everything on it, still no boot. I tried putting another CPU and still the same problem. At the end I tried different stick of RAM just in case, and guess what it worked. So I was really dumb.

Seems your RAM disagreed with your living room.... Glad it is solved.
