burning smell from pc

hi, recently i hooked up my new 42" hdtv to my pc via hdmi cable. about 2 days after i smelled a burning smell coming from my pc.i cant exactly tell where its coming from. i would suspect the power supply or video card. i shut my pc off for a day and then started it up again. still smelled the burning smell but not as bad. did the tv make my video card use too much power or overheat it? any ideas? specs

windows7 homepremium 64bit
ultra lsp 650w p/s
xfx radeon 5750 hd 1 gb ddr3
4gb corsair ddr3 memory

 

Most likely coincidence.

 

so it wasnt cause if the tv? what is it?

 

ultra lsp 650w p/s low quality not recommended

it output is less than a quality 550w

you need to look inside the computer for signs of burning [discoloration]

m/b
video card
ram slots
power slots ect.
