Re: can't turn my compuer on
Check on *********** board that your CMOS jumper is in normal mode otherwise change it - also check any beep sound aswell as you remove all the cables ie.. IDE cables, front panel cables I mean only the 2 power cables to the motherboard and try to start the pc by shorting the power switch pin with a screwdriver see the display coming or not ????
IF it is a branded pc - you have to buy the same companies motherboard, normal motherboard will not work with branded pcs.

It could have a loose connection with either the power cord, data cord, or display board unless it is a built in display board on mother board. You could try either plugging in another monitor or installing a display board.
1. turn off the computer
2. disconnect the VGA connector (the cable from the monitor)
3. remove the video card from the motherboard
4. the motherboard has the on board video controller, connect your VGA monitor to that slot.
5. turn on the computer, I hope by now your monitor is ok ;-)
The monitor should be plug and play, and you've already figured out that it's not your computer by plugging into a working monitor.
This is most likely the power inverter board in the monitor - this is
common in many monitors. If the power light is blinking on-and-off, or just staying on with no image, that's
the problem. There is a slight chance that it could be the light itself, but inverters fail more commonly.
If it's under warranty, send it back, if not, there are
inverter boards for many common models of LCD monitors that are
replaceable. The board can run anywhere from $50 on up. Depending on
how old it is, you may find it better to just replace it with a gently
used one from ebay.
Sounds like the cable that connects the monitor to the computer hass a loose wire connection in it. When it turns green, try flexing the cable near the connectors and see if the color changes on the monitor. I suspect that you have a wire in the cable that was not soldered properly by the manufacture. If it changes color, I'd contact who you bought it from and have them replace it. Hope thid helps. Bud
Can I assume (?) you re-tried firmly checking each cable connection and the power supply is soundly in place including checking the fuse in the plug That's all I can suggest as the things I would do if in your shoes.
if the monitor works fine on your laptop, the problem definitely is at the computer, possibly with the video card (if it is using one). it could have loose connection, or parts might have damages. it seems the problem is intermittent so electronic component of the video card could have parts partially damages or leaky components. if your still using the motherboards built in video out put, try installing a new video card.
my goodness.. you have spent a lot in your computer i think.. i dont think changing mother board and installing a new vedio card will solve this problem. as u have said that u have installed a new card make sure that you are giving the connections of your monitor to the gforce card and not to the mother board again.
if connection for monitor is going for gforce properly your RAM is the problem. as per your configuration its single 512mb ram. i would advice you to go and get another DDR RAM(same 512 prefrably) from any of your friend and put it in you mother board in by removing the normal RAM you had. this will work for sure i think. if this is not working dont rate me in-approtiate. i just triend my best. sorry and tahnks.. good luck
