I have a HP Slimline computer that has recently been having problems and thought it was the monitor but I have confirmed that it is not the monitor and is something within the computer. I think it is the onboard video that has gone bad because the monitor now says something along the lines of "Analog Power Saving Mode" on the monitor when the computer boots up. Would this be the video card, if not what do you suspect it is? I am going to buy a new graphics card for it (low profile card around $45 or so nothing powerful whatsoever), but was wondering if the power supply can handle an independent graphics card. Any suggestions on a fix for this? Any help is great.
