Hello!
I have a one year old system that has suddenly died completely on me. I have a warranty with the company I purchased it from and have just received a brand new power supply. I was convinced it was a problem with the power supply but the new one doesn't work either! Absolutely nothing happens when I try to turn on the machine.
The machine died in the middle of the night, after running normally over the past year. Is there anything I can try before I send the whole thing back? I have taken out the graphics card and unplugged the DVD and hard drive. I connected both of the power connections, the 24 pin and the 4 pin, but no luck. I have also tried taking out the battery to the CMOS and putting it back in to reset it but no luck there either. Could it be so simple that this battery is dead and the motherboard can't send a signal to the power supply to start?
Am I looking at a burned out/defective motherboard? I haven't found any posts anywhere related to this specific motherboard, I assume that if this was a common problem someone would have posted it somewhere...
AMD Athlon 64 X2 6000+ 3.0 GHz Socket AM2 2MB
2048 MB DDR2 RAM
Radeon HD 2600 XT 256 MB
MSI K9AGM2-FIH Motherboard
Seagate Barracuda 500GB Harddrive
"Silver Power" 500W Power Supply
Windows XP SP3I have had the system since September 2007.
I have posted my problem on a few other sites and have recieved following advice.
Reseat the 24 pin atx connector, the molex connector, the cpu fan connector...any of these unseated could cause a similar problem. Are you certain a CPU/Heatsink leg didn't pop up?
I also think it is power supply related, but you put another one in, so that takes some of the suspicion away from that issue. However, there are times in my shop when I have gotten a new one that is DOA, so we can't dismiss that altogether.
Pull all the memory out and see if the board beeps at you. See if you can find a friend who will let you try his/her power supply in there to see if it will start.
Take a paper clip and short across the two pins (remove the wire temporatily) that the off/on wire go to on the motherboard. Don't hold it on there, but just short across those two pins for an instant to see if the board turns on while plugged in.
I have tried everything except switching out the power supply (I was going to try using the new power supply in an older machine to see if it works...)
Anyone with some new suggestions?

Another silly question but have you verified there is power to the power supply? You know, blown fuse or powerstrip, etc.
Are you getting any lights or fan activity on the board at all?

If you have a brand name system, what is it's make and model?
...."Silly question but have you checked that the Kettle Lead Fuse is OK ??"
Power supply cords in the UK and Europe often have a fuse in the cord - it may have blown.
However, if you used the cord that came with the new power supply, that couldn't be your problem.
....Is it possible the computer experienced a power outage or disturbance that caused a power spike or surge, and/or were there any lightning strikes in your area on that night?
Is your computer and everything that plugs into AC power that connects to it, and the cable that connects it to the internet, plugged into something that protect against power spikes and surges?
Lightning strikes can do random damage even if you do have such protection.
......The one thing that can often not be made as well these days as they were in the past is the computer power supply - there are a lot of el-cheapo power supplies out there - they tend to fail more often, and when they do fail they are a lot more likely to damage the mboard or something connected to it.
E.g. Emachines systems, and some other brand name systems, use BESTEC power supplies, and they are a lot more likely to fry the mboard when they fail completely.What is the make and model of the original power supply?
Check your original PS for damage you can see.
See response 4 in this:
http://www.computing.net/hardware/w...If the original PS has fried the mboard, chances are very good replacing the mboard will cure your problem - usually the cpu, ram, cards in slots, and the drives are still okay.
However, I've seen cases where the floppy drive, optical drives, cards in slots, and much less often the cpu, have been fried, in that order of frequency, and I've heard of cases where the hard drive has been fried, and of cases where the USB on the mboard has been fried but everything else on the mboard works. I've never seen a case where the ram was damaged, but that's possible.El-cheapo power supplies have as little as a 90 day warranty, some have a 1 year one. Better power supplies are warrantied for 3 years, or some have a liftime warranty.
The warranty of any power supply only covers the replacement of the power supply itself - if it damaged something else while failing that's not covered.
Some devices that protect against power spikes and surges have a warranty that covers damage to connected equipment, but
- everything that plugs into AC power that connects to the computer, and the cable that connects it to the internet, must have been plugged into it
- the warranty is void if you used an extension cord between the cord for the device and the AC source
- if you have more that one such device, the warranty may not apply if they were not all made by the same manufacturer
- you have to send the protection device and the damaged pieces somewhere, or have a report made by a local professional repair person, in order to validate your claim.
.....It is extremely rare for you to have any problem with the power swutch on the computer case, but on some cases it is possible for the button to get stuck so the power switch is always depressed, in which case , at best, the computer might start but shut down in about 4 seconds, depending on bios settings.
Breifly shorting the two pins on the mboard for the power switch accomplishes the same thing as the power switch does - if everything is fine and it's just the switch that's no good, the computer should start up fine.
If your case has a reset switch, it is the same type as the power switch on an ATX case (momentary contact - on only when pressed) - you can hook up the reset switch to the pins for the power switch, and visa versa.
......If the ram works in another mboard that proves there's nothing with it, but if it doesn't, that doesn't necessary prove it's bad. The ram has to be compatible with the memory controller of the other mboard's chipset, or on some recent mboards, compatible with the memory controller built into the other mboard's cpu. If the ram doesn't work in the other mboard, it is a lot more likely it is incompatible with that mboard or cpu than it is actually bad, unless you can confirm the ram should work in the other mboard because it is on a list of modules compatible with it found by using your mboard model to search with on a ram manufacturer's or major distributor's web site.
.....In your case.....
- the ram should work on any AM2 or AM2+ mboard because it's the cpu's built in memory controller it has to be cpmpatible with, and your cpu should work on any AM2 mboard that supports a 6000+ cpu (all but the earlier ones), or on any AM2+ mboard with 800mhz (PC6400) or a slower mhz DDR2 ram.
- you could try the replacement PS, and the original PS if you see no damage, and your cards and drives, with another system.
However, don't try to boot the other system with your hard drive that Windows boots from - you just want to confirm it works and the data is still there. The reason for that is, if the chipsets of the two mboards are more than a little different, XP will often not load in that case - typically you see the first bit of Windows graphics, then a black screen, blinking cursor top left, and nothing further happens - that's normal, and can be fixed, if you need to that, without you losing data.
.....

Thanks for all the replies!
I live in Sweden, and I am pretty sure that the fuse you refer to is not on my type of power cord.
The original power supply was sent back to the distributer, so I can't check it for obvious damage, but it looked ok when I sent it back, I didn't notice anything out of the ordinary.
I don't remeber the name of the original power supply, the system was put together from seperate parts at the Swedish computer supply store, www.komplett.se, they have a good reputation for doing that, so it isn't a "package system".
No unusual weather or lightning that night either (it was Halloween... but still.)
I am getting NO power when I start it up, no fans/lights or anything. I have tried the go around with "shorting" the power switch but no luck there either. I have also disconnected everything, including memory, HDD, DVD, graphics card, still no power, no nothing. I am going to try lighting up an older computer that I have at home with the new power supply to make sure there is no problem with the new one.

A kettle lead is also known as a mains lead and they should have a fuse in the plug which plugs into the wall mains socket..

I live in Canada - computer power supplies sold here and in the US do not have the fuse in the cord. I'm not sure where a fuse would be in it if you had one - since it's described as a kettle lead fuse, I assume it would be like for a cord I've seen for some electric kettles here - in the connector on the end that plugs into the power supply. In any case, if you are using the power cord that came with the new PS the fuse would not be blown, if you had one.
All PSs I've seen the insides of have a fuse inside the PS on the board. If the power supply has failed it usually has not blown, and if it has blown, if you replace it, it has always blown again right away for me when the AC to the PS is restored.
This is unlikely but possible -
Many PSs have a recessed slide switch, often red, on the back near the fan outlet that can be set to 230 (or 220) or 115 (or 110) - it must be set to whatever AC voltage you are using, all the way to one side, one way or the other. Normally that's already correct if you bought it in your own country, but it may not be if you bought the PS off the web."I don't remeber the name of the original power supply, the system was put together from seperate parts at the Swedish computer supply store,.... "
Do you have the original bill(s)?
If you do, the PS, or the case with included PS, should be on that.I missed seeing you stated you have a Silver Power 500 watt power supply.
I assume that's the new one?I found some info...
"If you're wondering who Silver Power is - look no further than to its parent company: Maxpoint in Germany (or Nanopoint in the UK), and you may be more familiar with the Tagan brand, which it also manufacturers. In the past, Silver Power has found its way into many pre-built machines sold by large brands, but only recently has the brand made its way into the channel for us to buy."
"While Tagan is orientated towards the performance end of the market, and usually commands a "competitive" premium for its products, the Silver Power brand is a departure from this as it offers an extremely aggressive focus on value. "So it's not an el-cheapo power supply, but it's not top end either.
Current model - SP-SS500
http://www.maxpoint.de/en/products/...Has a 2 year warranty.
......"Could it be so simple that this battery is dead and the motherboard can't send a signal to the power supply to start?"
NO.
The typical button battery used on a mboard usually lasts at least 5 years.
If that were all that was wrong, or if the battery is installed upside down (+ should be on the top), the mboard still boots, but you would get a "Cmos Checksum Error" or similar message every time you boot, and the time and date and other customized settings in the bios Setup would be set to defaults.
Usually you can still then boot into Windows by pressing a specified key, but you should at least correct the time and date, either in the bios Setup or in Windows.
.....A working mboard with a cpu and video adapter installed should boot even if there are no drives connected to it, as long as ram has been installed and a 3 or 4 wire cpu fan is connected to a cpu fan header on the mboard, but you will get error messages right away, depending on bios settings (e.g. keyboard not detected, if it's not plugged in; operating system not found, or similar, etc.).
Some more recent mboards will not boot, or will boot but will shut down in a few seconds, if a 3 or 4 wire cpu fan is NOT connected to a cpu fan header on the mboard, or if no rpm is detected from the fan.
If wiring is hooked up so you can hear mboard beeps, when you try to boot...
- if no ram is installed, you should hear a beep pattern indicating no ram or a ram problem .
- if ram is installed but a video adapter is not, or if it is not getting a good connection in it's slot, you should hear a different beep pattern
- if nothing is wrong you usually hear just one beep

In addition to the advice above, have you checked the CMOS battery with a battery tester ? Or if you don't have a tester, you could try replacing it with a new battery.

Today I was given the advice to take out my compnents and try them outside of my tower. The problem may be due to a ground fault. I will give it a shot later tonight and see how it goes.

"Today I was given the advice to take out my compnents and try them..."
See the latter 3 parts of response 4, and response 7.
Did you check the voltage the switch on the back of the PS is set to, if applicable?
Did you try the replacement PS with another computer?
Did you find the original bill for the system?
If the system worked fine for a year, you probably do not have a ground fault, unless it's external to the computer.
Sometimes when someone assembles a system , they have installed a metal mboard mounting post or spacer in the wrong place (where there is no screw hole thru the board) and that can touch the wrong place and cause a ground fault or other problem, but that probably doesn't apply since it worked fine for a year.
The case PS must be connected via a three wire cord and grounded plug and be plugged into a properly grounded AC outlet.
You can use an inexpensive testing device or a volt/ohm meter to check the wall outlet if in doubt.
Even if you have a two wire connection at some point between the computer and the AC source, the computer should still work, but it might behave a little flakey.
......Your most likey scenario is the original power supply failed.
If the replacement PS works with another computer, there's nothing wrong with it.
If the confimed working replacement PS doesn't work with your system, then the mboard is probably damaged, and there's a very good chance if you replace the mboard your system will then work fine.
