I recently upgraded from a nVidia GeForce 5500fx oc 128mb to the x850 and now I have a couple of problems. I've looked every where to find answers but no luck. Hope someone here can help. 1. Monitor will go black / into standby stating no display after playing FEAR or Doom 3 for random amounts of time. Ati Tool is running, showing a temp. no higher than 71 degrees C. 2. Screen color freezes and garbles into unviewable status. Happens less random than above problem. Also gets bluw screen stating memory dump due to various factors. Some exceptions are: 1. 0x0000008E (0xC0000005, 0xBF01EB38, 0xB6FF1074, 0x00000000) 0x0000004E 2. ati2dvag.dll - address BF01EB38 base at BF012000 datestamp 41C8DD00 3. PFN_LIST_CORRUPT I've DL'd the most recent drivers for the Asus av78x-x mother board. installed the drivers that came with the x850 cd, also bumped up to Cat 5.11. Completely wiped the old nVidia drivers from the comp using Driver Cleaner Pro. I am getting seriously pissed at this since I have no real problems with the nVidia. Any help would be appreciated.
