my computer works fine any time i'm just surfing the web or using generic programs for business, etc, but when i turn on a game (WoW or even Vista version of solitaire) or watch an HD video the monitor will 'blink.' it turns off for just a few seconds then comes back on. i don't even think saying that it turns off is a fair way of saying it. the light on my monitor never changes from its' blue (normal) state. i'm assuming that means that the feed from the video card is being interrupted somehow. it makes playing pretty much anything impossible as sometimes a 'blink' will only be 1-2 seconds but other times it will last up to 5 seconds. it can also end up 'blinking' immediately after coming back from a previous 'blink.' the video card is a bit old, but psu is fairly new. psu is showing signs of wear, tho. the fan has troubles starting up sometimes. a few power outages a couple weeks ago i think is to blame. my question is, without buying all new components to test which one is to blame, is there any way to tell what's causing the problem? since my video card is a bit old now anyway, should i just upgrade both regardless of what the issue is? (video card: Radeon x1950Pro. PSU: Cooler Master 650W)

Since either the PSU or video card [or even both] the only way I would know of to determine which it is, without buying anything , would be to install the video card in another computer & try playing a game with it.
