Motherboard my pc is maybe shorted due of it starts whenever i plug it in with out the power switch? and it has no view on the monitor

Apply new turmal compound to your cpu and try to start again

Hi,
If a PC switches off the moment you plug in a screen its normally a indication of faulty VGA Card or damaged addon slot which is causing a short. Hard to say which of the 2 might be the cause only way to test is by installing other vga card and see if it still does the same.

Regards

Disconnect everything from the mother board except the power supply. ie no ram, drives and any front panel cables including any sound/headphone jack sockets. All you should now have is the processor and vga to a monitor. If when shorting the power on terminals nothing still happens, remove the battery and wait 5 mins. Short the rtc jumper and see if it will start now. If nothing then motherboard is scrap.

Remove the 2 wires from the motherboard which connect the switch and start the PC by shorting the 2 pins with a screwdriver for 2 secs and see if it starts without failing. Cheers from Scott and plz vote

Starting at the begining. The wall socket, the plug, the cable, the power socket on the SMPS at the back of your PC, the SMPS, the Output connectors from the SMPS to the motherboard. The power LED not glowing means that the power is not reaching the motherboard. Disconnect and reconnect the power connector on the motherboard. start. No start. Does the fan on the SMPS work? If yes then all components before the SMPS are doing fine. If no then most likely connection socket power cable to the SMPS may be the culprit. This has a lot of load on it. The PC and the monitor both take power from this socket. the answer to your problem lies in the answer to my question whether the fan starts in the SMPS or not. If yes then there is no output from the SMPS and the SMPS need to be given the due attention and if no then there is no power input to the SMPS and various cables and socketc need that attention. In case you need to and can remove and open the SMPS look for bulged or burst capacitors. If found, replace them. Those round cylindrical components.

Most screens will show nothing or go to power saving mode until the PC is turned on. The monitors need a signal in order to be 'active'.
From your description it could just as well be a problem with the PC rather than the monitor. The easiest way to find out is to connect another PC or laptop to the screen or connect another monitor to the PC unit.

Did you try pressing the Del key or F2 key when you turn on the unit to get into the Bios?

On the mother board at the front are 2 rows of pins to which wires are attached, going to switch(power) and the manual reset and the LED's. Usually the first 2 sets of wires--pairs of Green&White and red/black&white are for power and reset. Once u pull out the jumper-like attachments u will be able to see whats written on them. Isolate the power & reset wires. Remove them fron the pins on the motherboard. Switch on ur UPS and by simply shorting 2 pins, starts the PC. Now that u have identified the power pins, put them back after cleaning the dust,etc. If the PC behaves as before but works perfectly when the power switch connections are opened & PC works normally after just touching the 2 oins, then the switch need to be replaced......sodeep

This maybe due to lack of Video Card/Monitor drivers or the resolution is set to a small size. You will have to find out which video card you have, and if you have an LCD sometimes they come with drivers (Samsung LCDs have drivers). To find out what video card you have, you can usually go off the model name and number of your computer and get the drivers from your manufacturer's website. If it is a home built computer, you will have to look at the card/motherboard model and serial numbers to figure out the video card they use. Normally XP has a default video driver and it should not do a miniature resolution, but it happens sometimes.

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.

check to see if the power box comes on, if not replace it, when if it still does not work replace the motherboard. most of the time when the power box goes out the motherboard goes out as well. it shorts out. you can get the numbers off the box and the board and you can find replacements on ebay cheep.
