okay so my power went out and when it came back on it fried the power supply, i got that fixed but my samsung tv says the resolution is not right even though nothing has changed. This leads me to believe my graphics card got screwed up by the power surge and now is screwing up or something, first can you tell me if that is plausible? second I want to know if I can unplug my graphics card and turn on my computer and is their any chance it would then work? I don't exactly know what a graphics card does for all I know the thing could be not broken if you don't think it is the graphics card could you tell me what you think it might be? I will of course replace my graphics card but just want to know if that is an easy way of finding the problem. the bios screen does not come up when I turn it on and neither does safety mode and it will work on a computer monitor but I need it for my tv.

it's a desktop and the guy at the computer place showed me it was working with a normal computer monitor so yeah they work. and I don't really know the model I sorta just had the computer place build me the best computer they could for my money its a bunch of different parts and I don 't have a list of them.

okay but I cant until I have a screen but thanks for the websites, so if I replace the graphics card do you think it will fix it?

there is no point I already know it works on a different monitor.
