I just started to get this screen popup:http://forums.avsim.net/user_files/133299.jpgwhen i click troubleshoot i get ths:http://forums.avsim.net/user_files/133302.jpgI know the card is plugged in because i had the case open for cleaning a few days ago and the PSU is a 550w, so there is another problem; the PSU is only about 18 months old, but i do have my system on almost every day for ell over 12 hours.There is another problem that i have been experiencing for a while; when i try to start the PC imediatly after turning on the power from the wall the system starts to go but stops before there is any activity, just powering the fans for a moment then stoppng, if i turn the power from the wall on and wait a little while or leave the power on all the time the PC starts up no problem. I also have rather a lot of USB devices pluggr in the the system (about 10).any ideas folks?

I've ordered a new PSU, a 480w but that should be powerful enough, for what i have in the rig, i have 3 hard drives but only one optical drive although i do have 2 monitors runnig from the grafix card, hopefully that should cure the problem as the PSU i have was fairly cheap and could be going west :)

a new power unit cured the poblems.
