Hi I have a PC that just stopped working for me. The problem occured after I had shut down the pc for a few hours. When I tried to start it again it ran for 2-5 sceonds and then it powered off. I tried to start it a couple of times and one time I could see the BIOS boot text and then the text became blurry and flickered and then it hanged but the power was still on. When I restarted it, it powered odd after a couple of seconds again. First I thought it was problem with the graphic card, replaced it with a old card with the same result, except it don't power off after a few seconds but the screen flicker and looks really weird. I also put the orignial graphics card in another computer and it worked. I cannot access BIOS setup at any time and all fans are running. Later this day I will try to disconnect hdd and cd-roms and stuff to see if I could get it to boot. I will also try to use the pd Can it be something else than the graphic circuits/mobo that causes this behavior? Could it be a psu error? One idea, when I am using the original graphic card the computer powers off. This graphic card has a power connector but the one I use when the computer doesn't power off doesn't have a power connector. It gets its power from the AGP-port. Could this indicate a PSU problem? Any suggestion is more than welcome!
