Last night I was having problems with my iPod so I updated Itunes to the newest version. It wanted to restart my computer so I did. After it restarted nothing came onto the monitor. I tried again and still nothing. I thought maybe the video card dislodged so I re-set it and tried again. Still nothing on the monitor. I have now disconnected everything from the motherboard except CPU, RAM, and Video Card. I still get no display on the monitor. I have tried another monitor and same result. I think the motherboard is probably fried. What are your thoughts?

"I updated Itunes to the newest version. It wanted to restart my computer so I did. After it restarted nothing came onto the monitor"

Updating the Itunes software can't cause no boot at all.
No video is almost always merely a symptom - usually there's nothing wrong with the video hardware or the mboard or the monitor.
No video usually doesn't indicate your mboard is fried either.

Most likely:

1. Failing power supplies are common and can cause your symptoms.
Check your PS.
See response 4 in this:
http://www.computing.net/hardware/w...

If your power supply IS fried, whether it damaged the mboard or anything connected to it is unfortunately random. If the PS is a better brand, it is a lot more likely just installing another PS will get the computer working again.

2. A common thing that can happen with ram that worked fine previously is the ram has developed a poor connection in it's slot(s).
This usually happens a long time after the ram was installed, but it can happen after moving the computer case from one place to another, and I've had even new modules that needed to have their contacts cleaned.

See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:

3. A lot less likely.
Make sure the CPU fan spins when the mboard is powered on. If you have no power to the fan check it on another computer, and/or try turning it with a finger - it should move in jumps, but should spin easily. If it doesn't spin, if the computer is still working, don't use the computer until the fan has been replaced - the cpu can burn out in a few minutes or less; if the computer doesn't work the cpu may already be damaged to the point it is fried.
If the cpu fan or heatsink has accumulted mung (dust, lint, etc.) on it, remove it - if it has a cpu fan, remove the fan to properly clean it's underside and the top of the heatsink. If it has a cpu fan and it makes rattling or rumbling or screeching noises, most likely to be heard when the computer is started after it has cooled to room temp, replace the fan as soon as you can - it will probably eventually stop spinning if you don't.

Since you've eliminated the monitor, I suggest you go ahead & reseat the RAM, if that does not help .... your video card is probably hosed :-(

I went and bought a new power supply (Antec, current one is Rosewil) and that didn't solve the problem. I have re-sat the RAM and even tried using different slots and only one of the two RAM sticks. Also did not solve the problem. The CPU fan doesn't ave any problems and is still spinning just fine.

Do you have onboard video which you could try ?

Antec is an excellent brand.
Make sure you also plug in any extra PS connector from the PS for the mboard if it requires it, often 4 pin, as well as the main connector.

Rosewil or Rosewill?
Rosewill is a known good PS brand.
Rosewil is a cheaper brand, mixed opinions on the web about them, some say they're good (they're always good if you've had no problems), some say they're el-cheapo garbage.
If it's Rosewil, el-cheapo PSs are well known to be more likely to damage the mboard or anything connected to it when they fail.
Did you buy that PS yourself, or was it already in a case you bought? If so what is it's capacity rating and how much did you pay for it?

However, any PS can fail, and if it does certain things while failing - e.g. shorts or produces way too much DC voltage - it WILL damage something else, often the mboard, sometimes the cpu.

The video card could be damaged, but that's unlikely, unless you didn't remove the AC to the power supply when you were fiddling with it (see below).
Try it on another computer.

Try removing the AC to the case/power supply, unplugging it, restoring the AC, and trying to boot.
If nothing else is wrong, if you don't have onboard video, you will get a pattern of beeps that indicate no card is installed or there is a problem with the card (if the card is damaged enough you may get no beeps when it is installed).

By the way, is is IMPORTANT to remove the AC to the case/power supply whenever you make any changes to components or connections inside your case! ATX mboards are always powered in some places even when Windows is Shut Down or in Standby or Hibernate modes, and even if you have no drives at all installed, as long as live AC is being supplied to the power supply.
If the video card is AGP, it has two vertical levels of contacts on the card edge and in the slot that are staggered horizontally, and plugging in or unplugging the card when there is live AC to the PS can easily damage the card!

A failing or failed power supply usually does not damage the ram or the hard drive(s).

A long shot.

Your mboard may have the bad capacitor problem.

Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .

This was the original bad capacitor problem - has some example pictures.

- what the problem is caused by
- he says there are STILL bad capacitors on more recent mboards.
- a power supply failing can also physically damage the mboard - some details here.
- links on left to economical available premade or custom capacitor kits, and/or you can ship the mboard to him and he will replace the capacitors for a flat $45 fee (including the capacitors) plus $15 shipping, and up (North America only).
