Hey guys, got a pretty bad problem going on over here.

So I had to buy a new PC today (My **** of an ex stole my good one, :\) and got it pretty cheap.

Problem was, the specs are decent for the money I paid, except when it came to the GPU. GPU was pretty awful, sitting at 128MB of ram, so I threw in an old one I had from an older PC, yet every time I open Minecraft it completely freezes my system. I can move the mouse for 1-2 seconds before it locks up. Needs a hard boot after that point. But before putting in the new GPU, Minecraft ran fine. It also ran fine on it's original PC. I also swapped out for a more powerful PSU which was in the same computer as the GPU before hand. The PC the GPU and PSU were in, was a much more powerful machine than this one, so I don't believe it to be a PSU problem.

I've already given Java more ram, aswell as switch between 32-bit and 64-bit Java installations, and the only minor difference seems to be that when it locks up on the 64-bit version, little blues lines appear all over the screen and flicker constantly, the 32-bit version doesn't do this.

Note: This only appears to happen in Minecraft, any other game or application seems to be working fine such as Firefox, Doom(Skulltag), Skype, using Youtube (To check flash) and a few other little programs like speccy, AVG and Speedfan. Minecraft seems to be the only culprit. My guess it's a Java problem that I'm unaware of, or know how to fix.

Any help would be appreciated.

Well if you said it worked fine on 32 bit then why not go back to 32 bit? I have 32 bit and i play on max at high fps with no lag.

Bear in mind, Minecraft is not particularily system efficient. It could be overloading something with the improved GPU. I am not the best with hardware but perhaps to put it into other words you may have a tap with high water flow and the pipes can't keep up?
Anything after the GPU might be overworked? It's just a shot in the dark.
