ccc auto tune problem

[thespacemonkeymafia]

Hi, I just installed a Gigabyte Radeon hd 4850 and was trying out the auto tune feature in ccc, but after it runs for a few min my monitor loses the signal from my card, the pc doesnt shut down or reboot in fact other than the monitor isnt getting a signal the pc seems to still be runing. I reboot and evrything seems fine but if i run the auto tune after a few min when the core clock reaches 720 i lose the signal to the monitor. I know its not over heating cuz the temp never goes higher than 55 degrees C. Can anyone tell me what the problem might be or why its doing this Ive looked around and it seems no one else has this problem, any suggestions will be greatly apreciated. Thanks in advance my pc specs are below.


Os: vista 32 bit
CPU: pentium 4 dual core 2x 2.8 ghz
ram: 2 gig pc 5200
psu: 500 watt
GPU: gigabyte hd 4850 with aftermarket Zalman vf830 fan and heatsink

Completely normal on Vista. The autotune feature is broken. You have to do it manually.

Thank you very much, i was hoping that it was just vista. Of course if I said somthing to microsoft though they probably would have blamed it on ati just like they blame most of thiere bugs on the other software instead of thiers.
