i just built my new pc... had all the parts ordered from newegg and zipzoomfly...i had the computer running for about two days...then last night i went to bed and came down this morning to find that the monitor was in power save mode.....completely blank screen...i rebooted the computer...it still recognizes my mouse and keyboard, and the mobo seems to have power and all....but still no display at all on the monitor... the video card is an ATI RADEON HD 4850 Sapphire 512 gddr3... the video card has power as well... the fan and everything on it is working....so then i thought maybe my problem was the monitor..so i hooked it up to an old pc..and it works just fine...i even reseated the memory too...any ideas what the problem is or how to fix it??
