The power supply burned out. replaced it. Still I get, no signal

I get 'No Signal' display on monitor. Its not the cable, memory, these all have been checked. Computer is a Emachine T2200.

The video card is intergrated into the motherboard. I install an another video card in an extra slot, still nothing works?

any advise? Is board burned out. The Orange hard 'drive light' comes on when powered up, but it stays solid. It does NOT blink as if it was booting up. I tried other hard drives and none blink on.

any advise appreciated

Hi, the motherboard is dead, the cpu socket is blown and this results in a voltage surge through the plug that powers the cpu, this plug has 2 x yellow, 2 x black wires on it. The problem with these motherboards comes from the cpu socket which then blows the power supply, no the other way round. Have done hundreds of these boards for different poeple, need more support at compdoctor2005@btinternet.com

I have nothing to plug p3 and p4 into when all on no signal


Sometimes if a VGA cable is not screwed into to both your Tower and your Monitor, it can get loose and thus resulting in no signal.
Another cause of a Monitor Displaying the no signal message would be due to the Graphic Card failing, or possibly due to the Graphic Card not correctly being seated.

Other Thoughts
--------------------
Usually P3 and P4 refers to a cable on your power supply that needs to be attach to your motherboard to supply extra power.

Note:
If your P4 cable is not plugged in before turning on your computer, this will also result in your Monitor displaying the no signal message.
Keep in mind though, if your computer has not been opened or is not a custom built PC, you should not have to worry about such issues as your P4 cable should in theory be connected. However I guess safely checking won't hurt anyone.

Acer ASpire M1100 shows No Signal on monitor


Any time a monitor says "no signal" that message is originating from the monitor itself, and not from the computer. A monitor in a room by itself with no computer will say "no signal" for a brief time, if it is turned on. So, if you have tried other monitors also with no luck, then the problem is either the video adapter of the computer, or something that is keeping the computer from booting in the first place (power supply, hard drive, memory, motherboard). A power supply can be tested with an inexpensive tool. Everything else needs either a swap out with a known good stand-in, or else an expensive tool to know if it works.Does the fan come on when you turn the computer on? If so, maybe more likely to be the motherboard, hard disk, or memory. If not, more likely to be the power supply.

Monitor comes on but wont show picture


You should make sure the cable is plugged into the video port on the back of the tower. Also, if you have more than one video card, ie an "onboard card" and another card that was added later, try alternating one to the other and see if the other one works. You can identify video ports by finding the blue pentagonal plug. It also will be the only plug that your monitor cable fits into (that is describing a VGA cable, a white cable is a DVI cable and is even easier to identify.) You might also want to make sure the video card wasnt jostled out of place. The final solution could be you have developed some bad memory modules, or the memory was jostled out of its slot during the move.

No signal on first boot


This would usually indicate that there is a problem that is causing your computer to not boot correctly all of the time. What you have described could be many different problems and without more information I cannot say which one it is.

1. Hard drive. I have ran into Hard Drives that for some reason do not start up correctly right away when you put power to them. This can cause the initial startup to hang possibly indefinitely.
2. Video Card. Something probably firmware is causing your video card to not start up properly when power is first applied.
3. PSU. The power supply could cause similar problems if it cannot supply enough power because the highest power draw is when you first turn on the computer. When you push the reset button the power is already being supplied to most of the components and the ones that did not have enough power to start properly before can do so now.
4. CPU. If the CPU has some minor problems it can cause similar problems. In any case to fix it you can try clocking down the CPU but you are better off replacing it.
5. RAM. I have had similar problems with RAM. Clocking down the RAM fixed the issue.
6. Settings in BIOS. I would check to make sure the setting for init display on boot is set for PCI-e.
