Switched system on. Loud spark sound and smoke came from near power supply. Replaced power supply, absolutely no response from mother board. Fan does not come on, power supply does not start. Removed PB sw from header on mother board and closed switch circuit, nothing happened. Disconnected PS and took pin 14 (green line) to ground, Power supply kicked in. Look like mother board is dead. Are there any on board SMT fuses that can be checked? [email protected]Switched system on. Loud spark sound and smoke came from near power supply.

I have had the same problem and I don't remember how I fixed it now. Basically my computer was dead, if I unhooked the plug from the motherboard and replugged it the light would flash green and fan would spin. My computers working fine now. It's something really stupid OH okay there were two power plugs coming out of my power supply one 16 pin or whatever and one 4 pin and I had them both plugged into the motherboard.I have had the same problem and I don't remember how I fixed it now.

Electrolytic filter caps on the mother board have failed, and shorted. A dead short will sound like a gun firing inside the cabinet. A gradual short will make the can expand and split or work its way off the innards of the component
Gave up and replaced the MB with ASUS board; plugged the suspect CPU in, and it responded with a continuous beep. Plugged a suspected good CPU in it, and away it booted.

1- try to clear comos in the motherboard pcb behind the battery
2- take off your pcb from your case and put it on any thing metal and try again to open it
I was looking for a solution to my problem and ran across your post.
I have the same problem.
Here's what I found to get it working:
I put the RESET jumper on the PWR on/off posts.
Some reason the RESET button will turn my unit on, but the POWER button will not.
Another finding when hooked up "normal"... if I remove the power cable and plugit back in the PC boots up. The POWER button will turn the unit OFF... but will still not turn the PC ON.
So for now I am using my RESET button as my power switch. What I'm trying to find out now is "WHY?"
-Hope this helps!
Do you have a LAN connection on the machine that you use? That would be an area to start to make sure that (when a LAN cable is plugged in, the incoming and outgoing lights will blink) the power supply still works. If the power supply does still work, it could be the motherboard or CPU which isn't working. It could be something simple like thermal compound needs to be reaplied to the CPU, or there may be faulty hardware. Let me know if the power supply is still working.

i think your problem has been solved. thaks for using fixya
Unhook everything except power and your monitor. Put one stick of memory in and attempt to boot. Post here with results, what power supply you're using, what memory, and what processor.
Without a windows cd or recovery it is very hard. You should take some cd from somebody. At other hand, you can connect your hd to another pc and try program - hdd regenerator- on it.
This could be a few things though if you have already checked the memory and HD. The next thing I would tell you is that you should check the cpu. Also make sure that everything in the BIOS is set to the default settings when you start it.
I had the same symptoms on friends laptop. She had nothing to lose so gave me carte blanc.
Took out battery (to eliminate as problem) plugged in power, and powered up
Power light OK, HD flashed, CD flashed, then black screen. Powered down.
Did the following:
1) took cover off of fan/circuit board (see http://www.insidemylaptop.com/ for details). (4 screws)
2) take out fan (3 screws) and find huge amount of gunk on cooling fins at fan disch. Blew out with compressed air. Also cleaned fan blades.(reboot shows didn't fix.)
3) Repeated step 2, Pulled out memory sticks and cleaned terminals by rubbing with lint free cloth. Replaced memory sticks.
4) System boots normally. Replaced battery. Boots normally.
is there a post beep when the pc is switched on. check the memory if it is a beep beep beep sound , also disconect the hard drive, dvd drive, floppy, and any usb devices and see if it boots up. if that fails it does seem like the mother board, also check the cpu fan has it stoped. also find out the power switch conector on the mother board, from the base unit switch to the mother board. also chech the power connector from the power supply to the mother board , on newer boards there are two that go to the mother board its self , a big one and a very small one .
phalitao, you need to check you're power supply it may be bad.
No PC or notebook will boot without memory. However in your case I would recheck all power connections from the power supply to the board. Remove & reseat all power connections.
Please use you're manual help guide you. Also on the back of you're power supply (on most PSU's), there is a Red slide switch. Please make sure it is set to 115v & not 220v. After all this checking & you do not see life from the board, suggest you replace the power supply with a min wattage of 400w. Or borrow a PSU of 350w or better.
Please post back with you're findings.
