Question about Computers & Internet
Computer starts ,fans run,but nothing else works.Taken it to a shop and they say the mother board is no good.i have looked but can see no sign of components damaged of burnt.
Just because there is not visible damage to the components on a circuit board or the circuit board itself does not mean nothing is wrong with it. If your power supply tests ok and the rest of the ancillary components attached to the motherboard are ok, it is probably a bad component on the board. Usually it will be a bad voltage regulator or transistor that has gotten a voltage surge.

Do any of the fans plug into the wires going directly to the power supply? If so, you probably have a bad power supply. If they all plug into the motherboard, it could be the motherboard at fault, though usually when something fails because of the motherboard, it can still tell you what it was via beep codes and such. I would think the power supply is to blame, and the upside is that they are cheaper than the motherboards if you are interested in keeping this PC for a while longer.

SOURCE: Emachine Will not boot
different beeping patterns are codes which indicate what part of the hardware has failed (ram, video card, cpu, ect). the fan failure would not cause beeps, and would not cause the cpu to fail unless already in windows. if you could find out the manufacturer of your motherboard you could check with them about what the paticular pattern of beeps which you are getting mean.

SOURCE: No video signal to Monitor.
Lack of video signal is usually 1 of 3 things, Power supply (PSU), Video card or Motherboard (mobo).
Situation #1: If you get a blank screen and no sounds or movement it either indicates that the power supply unit (PSU) has failed or something on the motherboard has failed, preventing normal startup.
Situation #1A: You might get some power lights coming on and some fans spinning but the video output does not happen, usually indicates that motherboard is going out or has gone out. Ocasionally it will be due to a weak (damaged) PSU.
Situation #2: If you get sounds and lights but nothing on the screen then it indicates a failed or loose video card.
Always try a different power outlet that you know is working. (Eliminate the easy stuff first!)
If it is out of warranty, try opening up the case, with the power off, of course. If you have Sit #2 and have a video card that you can reseat (take out and then put back in) try that. If it is onboard video then you may have to buy a video card for it.
Also take this time to inspect the capacitors on the motherboard (they look like tiny soda cans) and check for tops that are bulging, swelling or leaking anything. Capacitors should be perfectly flat on top. If you find these then your motherboard is bad (well technically the capacitors on your motherboard are bad). The bad caps will need replacing to fix (not a job for an amateur). If it passes the visual inspection then it may just be your power supply is bad. Notice that a bad PSU does not mean you are getting no power, just not enough to start and run the computer.
A few years ago a company stole the recipe for making capacitors and started making their own capacitors at really cheap prices. The stolen "recipe" was not complete and not correct so these caps started failing after about 2-3 years of use. Emachines, DELL and Gateway were the computer companies most affected by the bad capacitor issues, although any of the big companies could have the same problem. Power supply maker were also affected by these bad caps.
Do you hear anything during startup, beeps, fans or drives spinning, lights on the front or back of computer flashing or lit up? Do you hear the Windows starting sound?
Let us know more then we can troubleshoot better.
