First check, using a voltmeter, to see if your power supply is working. Secondly, if it is, then reseat your boards and check all connections (internal and external) and try again. Lastly it could be as simple as the on switch is broken. By shorting the pins on the board where the on switch connects you can by pass this to determine if it is the switich. This should reveal your problem. Tango.

Intel D946GZIS machine will not start after being reassembled. The green light on the Motherboard is on but after hitting the power button nothing happens

It is more than likely the power supply that is faulty. Newer PSU's have a 5volt supply missing, this means that some older boards will not run with the new PSU's. Try and find an exact match for your older supply but with a better power rating, if that is what is required.

My Intel Core i3-530 Toast up 5 motherboard MSI H55M-E33. Im so lucky it was under warranty(RMA).. now question.. How to prevent processor from toasting the motherboard?? this is new to me.. any tips will...

Overheating is always a bad contact between the processor and the heat sink, or overclocking. Always check that there is nothing getting in the way of the heat sink making good contact. Things getting in the way happens a lot. After making sure there is a good contact surface, use heat sink compound.

You might be better with an Asus motherboard if it happens again.

Unable to power up System

Will the desktop even post? I would remove each component, one at a time, and try powering the pc up each time - i've seen issues w/ a processor/mobo being incompatible, causing the pc to not power up - also have seen issues where the power supply isn't strong enough to power the system...especially w/ the coolmaster cases. Do you have a 1000w supply to try to swap in the machine?

So, first pull the memory - try to get it to post - then h/d, etc.

Good luck - hope this helps!

Two sets of power leads to motherboard from pwr pk, 1 x 20 pin and a 4 pin, when the 4 pin isn't attached to the 8s651mp-rz motherboard the fans spin, the mother board light comes on, but then does...

The 4 pin connector is required as it provides the power for the CPU to run. if nothing is happening with the 4 pin connector plugged in then there is a problem. You need to make sure that you Power Supply can supply enough power for what you are connecting to it (400W would be the bare minimum with no high end video card, 500W would be recommended). You also need to make sure that the Power Supply is connected properly because some Power Supplies from pre-built systems from companies like Dell are wired differently than the standard power supplies. The only other likely problem is that there is a short on the motherboard either from the mounting of the motherboard in the case or from something on the motherboard being bad. Make sure there is no metal touching the motherboard except at the holes used for mounting.

Upgrading power supply

The next time you get a PSU. Tell them what you have. Apparently you got one that is not compatible with your compaq.The power (500 wattage) will work with your MB.
Get an OEM PSU from Compaq(HP).

Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.
