I don't have the manual for 277498-011

As for the Power Supply 99% sure it is an ATX which as long as you get the same Watt as the existing you will be okay. Make sure you look at your existing connectors to see if you have a 24 pin or 20pin motherboard and 4 pin or 8 pin additional power plug (black and yellow wires) and the new power supply has matching connectors....older ATX supplies have only 20 pins, but there are converters from 20 to 24 pin available.

Watch for the new power supplies and your drive connectors as some of the new power supplies have limited ATA plugs...if you have a lot of ATA devices you might need SATA power convertor plugs or ATA splitters to get all you ATA devices up.

Constant reboots, replaced most parts

check the capacitors on the motherboard near the cpu and ram. They're the little round cylinders found all over the board. If the tops are bulging out or there is a brownish goo coming out of any of them, this is your problem. Normally the top will be perfectly flat, but if the capacitor has failed it will do what i mentioned above. Sometimes, if it hasn't failed completely, it will cause the motherboard to reboot randomly. I would definitely replace the motherboard if you find this and it should fix your problem. While you're at it, buy another motherboard and CPU and build yourself another entire computer because all those other parts you replaced are still probably good.

HP MCP61PM-HM motherboard diagram

Hi RobPu,
I have searched everywhere. I even entered a chat windows with Compaq & asked for a site to download the manual for Compaq Presario SR5015LA Desktop PC which has the motherboard MCP61PM-HM in it. (Nothing). This board was made by
ECS known as EliteGroup. Still nothing. Forms for the most part do not help, only with drivers. Drivers for the board can be found on Compaq's web site.
But the manual will not download. That's what is needed to hook up the front panel pins to you're case. I even looked for other possible boards who's layout was close to the MCP61PM-HM.
Nothing! I did find other Compaq PC's that also had the same board in it but after looking through the manuals, not one actuallys shows where to plug the front panel LED's on to the board. Why? Because Compaq does not support a user changing out their case for another. There is no money in that.
For the most part RobPu, system boards share some things in common. I am posting a picture for you. This pic is upside down for you so try & work with me here. Hook up you're LED's as shown. This should work for you. Pin 1 is you're starting point.
daa3370.jpg This is standard for ECS boards even if it's being sold by Compaq. Like I mentioned, for you it is posted unside down.
Try it, I'm sure it will work for you.

If I can help you further, feel free to post.
Suggestions & comments welcomed.
