no live screen on bootup

hi thanks for any responses i think i have the problem solved but before i order a new power supply i wanted to get some answers or help to see if i am going in the right direction so heres the problem.

In the last week or so my wife normally plays eq2 and noticed the monitor was flickering and we thought possibly the monitor may be going out and jus yesterday we tried to start up the comp and nothing on the monitor at all when powering up, or no noise except for all the fans and hardrive, cd rom sounded normal and the fan of the power supply was blowing air out, just no normal bios screen or anything and a red light is showing below the green light, green light is the normal on light and i imagine the red light is a trouble light of some sort.

So anyways i have tried 2 different monitors no change have tried several other things inside the comp unhooking the vga vid card and trying the mobo video,and nothing has changed, so through the research i have done it seems the culprit is the power supply, so any advice would be greatly appreciated my comp is a 1.6 athlon, 256 mb gforce vga card ,1k mem ram, and the board is a asrock k7s41 ,and currently im running a 400 watt power supply hydro lp400b and a maxtor 40gb harddrive which i tried 2 different drives thinking maybe a hard drive problem no luck there, and also should i go over 400 watts?

I would suggest before you go replacing a power supply you try some other things first.

First try resetting bios settings.. since you cant see an output on your monitor go into the case and locate the cmos battery. remove the battery. NOTE: make sure POWER is disconnected while doing this.
While you have the battery removed from the system hit the power button and hold it in for aprox 60 seconds. this will discharge the capacitors on the motherboard and remove all power resetting your BIOS settings back to factory defaults.

put the battery back in and then reconnect the power cable. now see if it will power up. If that does not work you are looking at a couple different problem causing the problem. faulty processor can cause the computer to turn on and fans to work but not get a POST beep. it could be power supply but i doubt that since the computer is coming on.... most likely if resetting the BIOS doesn't fix your problem you will be looking at replacing the Processor....

hello again thanks for the response, I now know it is not a power source failure since i tried a good source coming from the comp i am on which is a 400 watt, and i tried to reset the bios as well , nothing changed still dont see anything on the monitor when i power up so im gonna ask around tomorrow and check back here, so far i removed the cmos battery as suggested and tried to jump the cmos jumpers without luck.

I am afraid your problem is a fried CPU then. i have seen this countless times. I would reset all internal cards... sound/video/network etc... then i would start looking for a new cpu.
