I have a fairly new(about a year old) gaming pc that I had build myself. I have had no problems with it until about a week ago when it started to not be able to connect to the monitor. The monitor is an ASUS im not sue which model though. So I went for the obvious stuff first.

I tried a new DVI cable and found out that wasn't it. Next I tried to hook it up to a television using an HDMI cable in at first the video card slot and when that failed, the motherboard slot. Still it had not worked. I then decided to open it up and maybe the power supply wasn't giving any power to the graphics card for some reason but the cards fan was blowing and every other fan worked, I checked my hard drive as well and the way my case is I cant see a light but I could hear and feel it humming.

I have no spare video cards to try to play around with, this being my first pc and all. I had also moved the ram to different slots such as 1&2 to 1&3 then 2&3 and so on and so forth yet no luck(my motherboard is an ASUS rock with 4 ram slots).

However I had a crazy power outage the other day where it went on and off maybe 3-4 times and my pc is not on a surge protector and you guessed it, it was on the whole time. I am starting to wonder if it may have fried something on my motherboard or even my graphics card for the matter. My graphics card is a radeon HD 6800. Also I want to add that even after the power outage I was able to get onto my computer and login. I just could not change the screen resolution for a crazy huge size and only had one resolution to choose from. The next day I just couldn't use the monitor at all.

Thanks in advance for the help.

well, like you said there were power issues

maybe check to see if the monitor cable is connected. For a while i thought my new system wasnt working when the issue was that the cable wasnt in all the way. maybe check that out, although it sounds like your problem was possibly different

Well I can't open the menu on the monitor for some reason. My friend told me to take everything out except the cpu and see if I can get to BIOS and I can't even do that, but when all of my stuff(video card sound card and ram honestly) not counting my hard drive the cpu fan won't move. I'm starting to think it is a power problem or my mobo is screwed.
