Hi, so here's the problem, I bought a brand new graphics card today, the problem is my monitor only has a VGA slot in it and the graphics card has HDMI and DVI. So I looked for the HDMI to VGA converter I had and used that, it was working well for awhile, no display issues at all, and then after awhile my monitor lost signal and this annoying high pitched ringing noise started, it seems to be coming from the adapter since everytime I unplug it and plug it back in, everything would work perfectly for awhile and then the same problem would start all over again. I tried using our TV directly and the problem doesn't occur with it. Is it advisable for me to buy a new HDMI to VGA adapter or is that a waste of money?
