My brother has an old Compaq Presario DR1610 NX and I have been helping him upgrade it. We changed the processor to a MD Athlon 64 x2 4200 + 2.2 GHz Dual Core and upgraded the power supply to 430w. For the graphics card, we found a ASUS NVIDIA GeForce 7950 GT on ebay. We turned it on and everything was working fine for a few minutes, then the screen froze, went fuzzy, and the computer turned off. We let it sit for awhile and tried it once more only to see sparks coming out of it. We turned it off again and found that it was the graphics card that was sparking. Did I get the wrong type of graphics card for this PC or to I get sold a bunk graphics card?
thank you
