hello there, my two years old recently caused my pc to shut off due to plugging in a faulty usb mx518 gamming mouse in to the usb port on the bottom of my pc, now the pc wont switch on at all. is this due to a short in the ps or maybe the motherboard?

if booting without RAM didn`t result in long beeps, then most likely you are experiencing either motherboard or cpu problem

before changing any, please reset bios to it`s defaults and also try to boot with cpu, vid card and ram only

ok...look...

there are bios codes that can help you to identify various computer problems...if it was the power supply, the system would have given short continuous beeps...

you can reset the bios without booting the system using the CMOS battery...simply take it out and put it back for a minute...

probfixer said "if it was the power supply, the system would have given short continuous beeps..."

This is pure nonsense. If the powersupply has failed you get NO BEEPS. You may get fans spinning but that is no guarantee the PSU hasn't failed. Since you aren't even getting any fans to spin your PSU is the prime suspect. PSUs provide several different output voltages and failure can occur in any one or more of those rails.

Without a known good PSU there is no way to determine if the short circuit caused more damage.

You do realize a bad power supply could conceivably damage the new motherboard too?

If the new power supply did not fix the problem then a decision could be made to scrap the computer. By the time a PSU, motherboard and processor are bought you could replace the computer.

Every time I've used a known-bad PSU on a known-good MB, the board didn't work properly (or at all) ever again. (my 2 cents)

*sigh* Bestec. But that's a story for a different thread...actually many different threads all at the same time.

OP's best hope is to return the items he received citing dead on arrival so they'll be sent back to manufacturer and tested (or trashed, however they do it), then if a new mb and cpu are necessary buy them at the same time as a new psu as well.

Also worth noting: a motherboard damaged by a bad power supply can then damage future power supplies as well. I've had it happen and that demon machine which needs a new psu every 6 months is now in the closet awaiting better days.

Starting the system with the CMOS jumper in the clear position can damage the motherboard.

adam
Now you need to evaluate exactly where you are. I am not sure if a bad motherboard can ruin a new power supply. I suppose it is possible if there were some sort of short in the board. That said, most of the time there is a power surge when a power supply go out and that can fry components on the board. Once that happens I don't think there is continuity anymore.

Bench testing a motherboard takes many components out of the loop so it is a good idea.

I suggest you try the new PSU with the new MB & CPU outside the case. Only things required are as follows:

MB with CPU/HS/fan, 1 stick of RAM, power supply connected to board including auxillary 12V connector, video (on board or add in), monitor and keyboard.

No case wiring, drives, external hardware other than mentioned. If the board POSTs then install back into the case. Start the board by momentarily shorting out the two pins that the power switch connect to.

Be sure you have properly applied thermal compound and you have the CPU fan connected to the header marked CPU fan. Double check the CMOS jumper is in the run position.

Do this. Remove ALL the wires from the case to the motherboard. Use a flat blade screw driver to temporarily short out the two pins the are marked pwr +-. That should start the board.

Do you have the 6 pin connector plugged into the graphics card and the auxillary power connector plugged directly into the motherboard? That is in addition to the 20/24 pin main power connector. The auxillary should be either a square 4 pin connector or an 8 pin with 2 rows of 4. Should be located somewhere near the CPU.

Set it in the run position. Verify in the manual. If there are 3 pins then the run position is usually 1&2. If only 2 pins then no jumper is the run configuration.

You don't hold down the Del key. You continuously tap it starting right after you turn on the computer.

Should even be a message on the screen stating to enter the setup hit Del.

I think you are at a dead end here. Where did you buy your components? If you have access to a shop you might get the power supplies tested to eliminate those.

Then RMA the new board. I doubt the CPU is bad but you could also RMA that.

Others here have indicated that a defective motherboard can ruin a good PSU. I have no knowledge of that so I can't say if it is true or not. I do know that a bad PSU can ruin a good board. I don't think anything you have done or stated could have ruined the RAM but I suppose if a shop could test things for you at least you wouldn't be blindly stumbling along.

Your new board has some frequency jumpers on it. I assume you never moved them. Near as I can determine from the manual they are use only when you are trying to overclock the CPU. It is possible that those jumpers could stop the board from POSTing if set wrong. The manual does address them.

Other than that I have no more suggestions at this time.

I said I would have corrected you if I had seen the thread before that point. I didn't come across it until after that.

The reason you suspect the PSU first is NOT because it is the cheapest. That may not even be true. It is because the PSU is susceptible to all sorts of issues. Mostly overloading of a cheap PSU or a voltage spike entering the PSU.

With all that has happened with adam's hardware is is best to have it tested or replaced. Until one knows what is good you can't troubleshoot.

adam a

If you are still with us I just thought of something. Are you located where you use 230VAC for house power? Setting the voltage selector switch at 115VAC when 230 is required will send double the voltages to all the hardware and would most certainly fry something. Conversely, setting to 230v when 115V is needed will result in boot failure but shouldn't damage hardware. The reason is that under those conditions you would be sending half the required voltages to the hardware. They simple wouldn't work.
