If it only freezes now when playing, then it might be DVD drive issues reading backups. Does it do fine playing normal DVD movies? What does it do with retail discs? if this is the case, then u should try the POT calibration tutorial and upgrade to latest firmware if you havent already.
Also how hot does that 250 watt heatgun go? The one I use is 1500 watts and goes up to 730C. I always use an infrared thermometer to make sure the chips get over 220C. Could be possible your heatgun didnt reflow the solder all the way if its not dvd drive issues.
thanks fpr the reply humboldt.. im playing the retail disc... i've updated the nxe as well..
if i left the xbox on its dashboard it also freeze after couples of minutes.. but playing game freeze it faster...
bout the 250 watt heatgun.. i tried it with thermometer and it reach 390-400+C.. i've tried it to my old broken cpu's motherboard and it works well on removing few chips.. hahaha.. yesterday i pissed off and i reheat my board for around 8+ minutes... (im ready to buy new unit if this one exploded or so i think) now the unit runs for 2 days without freeze but i only play it for 30 minutes or less each time... im kinda paranoid that the 3rod will be back and its been haunting me ever since..
