Some times when I start my computer the fans turn on, my screen is black, no post, and nothing happens, I would like to call it a "blackout" except the fans are on, but if you guys have some technical term for this, go for it. The only way I have figured out to fix this is to reset my CMOS which is a painstaking process which takes a while (because I have to take my video card out to get access to the battery and then reset the jumper). The first time the "blackout" happened to me I reset the CMOS, it turned on perfectly but now I have to reset the CMOS maybe three times for it to work. This gives me the idea that its not the CMOS, but hey I don't really know, of course that's why I'm here.

This "blackout" only has happened four or five times over the year I have had my computer. Here are some descriptions of when this happened.

- The first one was when I just got done building it and I turned it on for the very first time. Oh what a great feeling that was. But I reset the CMOS and all was normal.

- This happened a couple times when the power went out and the computer shut off. Some times it took 2 or 3 times at resetting the CMOS for it to boot properly.

- Now this last time was when I tapped the front of the case with my knee when it was turned on. The computer froze tight and when I restarted it I got the "blackout".

Now please don't get the idea that I am beating up the computer because I am not its always done this and I have read other people that have had this same problem, but hopefully we can get a fix.

Also when I use the term "blackout" it means when I turn the computer on the fans turn on, my screen is black, no post, and nothing happens, I just call it this so I don' have to restate the symptoms again.

Reconnect all cables, re-seat all cards & RAM.

Run Memtest+ overnight.

Try a different PSU.

Try your video card in a different PC. Try a different video card in your PC.

I had this exact same problem.

I'm having the motherboard replaced by the vendor
