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.

If your motherboard power lamp will be off/on automatically, it could be related to bad supply unplug all connection and plug it again proper if still you have same problem then you can try another OK power supply
Is the monitor turn ON. Is the monitor still connected to the computer. The graphic card is bad or your monitor is bad or the mother board is bad. Check to see if the fan is working in bark of the computer of the power unit when the computer is turn on. If it is not working then your power unit is bad.
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 ;-)
Try refreshing all connections to the motherboard. Also clean the RAM as shown in the image below. Resetting the CMOS may also help you in the process. Make sure that the power cable connected to the power supply is disconnected. Change the jumper settings of JCMOS1 (labled 1) from 1-2 to 2-3 for approximately 10secs. (refer to the image below).
Then return to original settings (1-2). Hope this helps.
When we say monitor doesn't turn on you need to check the power cable if it is correctly plug in, Check the monitor cord if it is plug in directly to your motherboard port. Some motherboard have installed external video card once you have install an video card you can plug your monitor cord to the video card. When the problem is still occur you need to disassemble the unit. The processor have problem it doesn't display. Remove it and clean after that put a thermal paste so that the heat from CPU will absorbed by the heatsink.
you need to shut down the computer and pull the power cord off powersupply then remove the wire harness that goes on to the mother board then press the and hold the computer on button for 3 seconds then plug in the the harness back on the mother board and and plug in all power cords then try to turn on the computer it should give u a beep or the monitor should go from orange to green good luck e-mail me if u want email@example.com
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
