I recently installed some new ram, a cd burner and a new video card. the card is a GeForce FX 5200. My computer worked flawlessly before this upgrade. Now it is freezing every now and then and it almost always freezes whenever it hibernates. I figured this was a power issue since my old power supply only supplied 123W and the video card alone required 150W. So I replaced the old power supply with a 300W one. I thought everything would work fine after that but my computer keeps freezing. Not nearly as much anymore but it does and it still always freezes whenever it hibernates. Could it be bad ram or something?
