Hey guys, yesterday, my computer was off, and my room's electricity cranked out, and I had to go reset a breaker. The electricity turns up fine. However, when I tried to boot up my computer again, I got a "Check Signal Cable" error on my Samsung 204BW 20" LCD, and the screen is blank (after doing the analog-digital switching thing a few times) The computer surprisingly boots up fine, I tried logging in (blind), and pressed enter, I get the Windows sound from my speakers, and I get the logoff when I Alt-F4 (again, blind) shut down. I tried the monitor using VGA with an older computer (it only has integrated graphics, and the monitor is fine. I was using DVI on my new rig, and tried VGA on that, no show. Now, I know the monitor is fine.....the Dvi cable should be fine too....(this is a 3-week old rig)....I'm running a Gigabyte EP35-DS3L, 2GB OCZ Plat, Rev2 DDR2 800, WD 640GB, Antec P182, and eVGA 8800GT.....now I'm tempted to blame it on the Graphic Card...maybe not sending signal?

I have a 30 day return policy on most of the stuff (including GPU)....but remember, my computer seems like it can still boot....
Try re-seating the graphics card and unplug the power to the monitor for about 10 minutes. Is everything running on a power bar with a surge protector?
