monitor not receiving signal from PC

May 13, 2012 at 12:36:29
Specs: Windows XP, Pentium 4, 1 GB ram
We've removed the power button ( took off the cap and I am using the actual switch inside to turn on PC). We've replaced the power box and the computer is turning on fine. The problem is that if I shut it down and then turn it on again (at any point), the monitor says signal not found ...or something to that effect. I have to do a hard shut down (because the screen is black) and wait for the charge to leave the CPU and then when I plug it in again the monitor will come back on.
This is a year old monitor that has only been used for a few months because the other monitor I had seemed to not be working anymore, but maybe it was the same problem.
My PC guy can't figure it out and I don't know what to do. Any ideas?

The power button on a tower/case rarely breaks & is rarely a problem. It's just a momentary switch like a doorbell button. A toggle type switch should NOT be used, in fact, it will damage your system. What type of switch did you replace it with?

"the monitor says signal not found"

That means just what it sounds like - the monitor isn't receiving a signal. The monitor is most likely OK, the problem is with the tower. For whatever reason, it's not sending a video signal to the monitor. Could be a bad video card, bad motherboard, bad/weak power supply, etc. It's impossible to say based on the info you provided.

"wait for the charge to leave the CPU"

Please don't call your tower a CPU. It urks a lot of people, including me. A CPU is a chip that fits in a socket on the motherboard.

What is the make/model/wattage & amperage specs of the new "power box"?
