650W is more than enough for a 7850. The PSU could be failing though, dont rule that out. It doesnt directly correlate to the main issue though.Like Chad hord said. It maybe the Psu is not putting out enough power. Either way you have a power problem here. Taking out the dvd rom. Is not the solution. I would run a check on the PSU, Plus the main board.

But if he plugs in the DVD drive, then it should work, because it would be using power.No its not odd. You have a power issue there some where. My guess is still the PSU. It may very well not be pushing its load correctly. I have seen PSU do lots of weird things when they are not good. Right down to just not working.
So I reassembled my pc last night and was glad to discover something that is not related to my main problem. I discovered that the front audio connection was not properly connected that is why im wondering why the heck there is no audio in the front panel. aside from that.. I have not seen any washers in my mobo. it was directly screwed to the case. but then I still continue and so far the pc now is working. I dont know when would be the time the problem will appear again. ill just update soon. thanks for the replies by the way!
