jesus 5 hours i got my matrix flashed it with x2 4977 and was playing in like 30 minutes at that was my first time. which bios are you using? one important thing was did you get the spacer you are suppose to get with your matrrix? it should be a little round spacer with a hole in it to give a little clearance so it doeant touch the board. did you get that? cause i didnt and i couldnt get it to level out and allign so i am using a bundle of black tape punched a hole in it, and vwala it worked you need sopmething to give a little space that could be a problem, also while you. see if that helps and see you must be dealligning it everytime you turn in off test mode i did that once to, what i did was as i was gently scewring the chip downwards i kind of nudged it a little in all directions and when it stayed on green i screwed it in a litle more and i never had to fix it again i even brang it to my buddies house no prob i have it for like 7 months now, the only thing is i have. i hope this helps.
