Intel Dual Core 2.0 GHz Sytem hangs after boot

The motherboard for the dc7600 has an Intel LGA775 processor socket. However, not all LGA775 processors are compatible with the motherboard. For the small form factor, the following CPUs are supported: Intel Celeron D Processors:
Intel Celeron D 331 Processor (2.66-GHz, 256K L2 cache, 533-MHz FSB) , Intel Celeron D 336 Processor (2.80-GHz, 256K L2 cache, 533-MHz FSB) , Intel Celeron D 346 Processor (3.06-GHz, 256K L2 cache, 533-MHz FSB)
Intel Pentium 4 Processors with HT Technology:
Intel Pentium 4 521 Processor (2.8-GHz, 1-MB L2 cache, 800-MHz FSB) , Intel Pentium 4 524 Processor (3.06-GHz, 1-MB L2 cache, 533-MHz FSB) , Intel Pentium 4 541 Processor (3.2-GHz, 1-MB L2 cache, 800-MHz FSB), Intel Pentium 4 620 Processor (2.8-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 630 Processor (3.0-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 631 Processor (3.0-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 640 Processor (3.2-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 641 Processor (3.2-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 650 Processor (3.4-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 651 Processor (3.4-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 661 Processor (3.6-GHz, 2-MB L2 cache, 800-MHz FSB) or
Intel Pentium D Dual Core Processors:
Intel Pentium D 805 Dual Core Processor (2.66-GHz, 2x1MB L2 cache, 533-MHz FSB), Intel Pentium D 820 Dual Core Processor (2.8-GHz, 2x1MB L2 cache, 800-MHz FSB), Intel Pentium D 915 Dual Core Processor (2.8-GHz, 2x2MB L2 cache, 800-MHz FSB), Intel Pentium D 925 Dual Core Processor (3.0-GHz, 2x2MB L2 cache, 800-MHz FSB), Intel Pentium D 930 Dual Core Processor (3.0-GHz, 2x2MB L2 cache, 800-MHz FSB), Intel Pentium D 940 Dual Core Processor (3.2-GHz, 2x2MB L2 cache, 800-MHz FSB), Intel Pentium D 945 Dual Core Processor (3.4-GHz, 2x2MB L2 cache, 800-MHz FSB), Intel Pentium D 950 Dual Core Processor (3.4-GHz, 2x2MB L2 cache, 800 MHz FSB)

Unfortunately, these are old processors and I don't see any available new. Newegg.com lists a couple available as refurbished. You may be better off getting a new computer with either a Intel I3 or current AMD processor.

I wish that I had better news for you.

(do not attempt to use a CPU that your motherboard doesn't support. It probably won't boot.)

MAC OS X can work in Intel computers but it might need to be cracked to install, In my opinion try dual booting your computer this mean making another partition on your hard drive to install MAC OS X to for the time being to see if it will work on your system and hardware

Do you have any extra things plugged into the usb ports? (external hard drive,Ipod,Flash drive) anything like that can sometimes cause pc's to hang at boot they will try to boot to that device instead of your hard drive

Try booting up in Safe Mode - press F8 function as the computer boots up, then use a WEB based virus removal to clean out the virus.

Have you tried booting it from yor CD drive with bootable software?

Any led flashing anywhere in the computer?

If not, we are talking about energy problem. Try fitting the energy cord firmly, try connecting the battery charger in a different power outlet.

Did you know that you would need to have a more powerful power supply?
Dual core cpu's need a minimum of 600 watt power supply.

hanging of system may several causes, first of all check for viruses un the system, check proper drivers installed in the devie manger.

Try using a different graphics card or make sure that you even have one installed in your computer. If no display is present on boot up, then your graphics card might be corrupt.

How much power is the power supply? Could be the power supply not having enough power for your rig.

Check the CPU fan (working) and heat sink as these over time clog up with fluff and dirt overheating CPU also check the rear of power supply for blocked ventilation holes
