since the problem only started after adding the graphics card and the memory it tends to point to the psu been to weak.
how many amps are on the 12volt rail? if its under 20 id definatly replace it especially if its a generic brand psu they can take out components when under strain just ask any one with a q-tec or a hiper psu :P
try putting one of these FSP psu's in your system very reliable and shouldnt take out any components if it goes bad as theres plenty of failsafes and its a good quality psu plus the 2 12 volt rails will give plenty power about 28 amps i think not looked at the sticker on mine for a while
FSP Sparkle Blue Storm 2 500W ATX2.0 PSU
btw one week before i rebuilt my system i put in my x800gto and my cpu points on my old sempron halved on 3dmark tests plus some stability problems = my old mercury "generic 400watt psu was struggling to hell oh it only had 17 amps on its only 12 volt rail and would of blown up big time if i kept it and i was getting similar symptoms to you"
even cpuz agreed the voltage was fluctuating a lot and that was a sempron 2800 socket A.
the fsp one is happily powering a 3700 a64 1 gig ddr400 a x800 etc plus 3 harddrives and 2 dvd drives and it will allow me to whack in a 8800gtx "possibly sli" on top of that when i get money and if i want one plus that psu is silent and wieghs about 10 times the weight of my old generic one
moral of the magical story is you get what you pay for and a decent brand psu will last for ages and not take out components when it blows and will last for at least one mainboard upgrade before struggling so kind of a future investment which results in a more stable pc and stable overclocking
on the old psu and my old graphics card there was a point i overclocked it to and my 3d marks started to drop.... same happened on cpu overclocks psu was to blame
