After 2 years the system is overheating and shutting down while trying to reboot it appears to be the cpu over heating however i have replaced the cpu with a known good one and it still does the same thing any help
I had a problem with my P4 overheating on that same board, I cleaned all the dust out of the heat sink and the coolant fan, then also angled another fan at 45 degree from the back to the CPU sounds like alot, but worked for me.
probly just ganna be a hastle so unless you think a fan would help dont bother

Following are the reasons for overheating, just take care of these things:: Stop Overclocking your CPU Make sure your Heat Sink is placed properly above the processor Clean the Processor fan, Heat Sink and other peripherals Use High Speed fans Use CPU Heat Sink Paste in the processor Use Additional Cooling Units Shut down your computer at least two hour a day Finally i will suggest you to get system utility program like PC Fresher to maintain your system performance
The laptop will need to be dismantled down to the motherboard level, use a can of compressed air attach straw and blow out all ports, heatsink and fan. It might be a good idea to remove both for closer inspection and several good blast of air for good measure, and check the thermal paste between the heatsink and processor ic has not dried out.
Sounds like you are overheating. One way to tell if it's overheating is you say it will run for about 30 minutes then shuts down. When it shuts down try rebooting to see if the boots successfully. If it fails to boot successfully right after it shut down then you are probably overheating. If you wait awhile to let it cool down for 30 minutes or so and if you reboot and it does it successfully you definitely have a overheating problem. If I remember correctly all those compaq sr series have loud and fast running fans. Computers overheat because of three reasons for the most part: 1) A fan has stopped working. 2) The Thermal Paste on the CPU and Heat Sink has dried up or is not thick enough to keep the unit cool. 3) Dust has clogged the fan vents and inside the computer. Fortunately for you desktops don't have to be completely disassembled like laptops to get to the fan, CPU and heatsink. Just pop the case and you'll see the components attached to the motherboard
There can be many reasons of unexpected shut down of your system.Below are some remedies to solve it
1 Run an anti-spy ware and anti-virus utility to make sure that the shutdowns aren't being caused by a malicious program. If the shutdowns are infrequent, install a CPU temperature monitor utility to keep track of the CPU's temperature. If the CPU is overheating, or the shutdowns are frequent, then you will need to troubleshoot your computer's internal components.
2 Check any recently installed internal components to ensure that they are properly connected to the computer's motherboard. Make sure any new expansion cards or memory modules are securely seated in their slots, and ensure that the power and data cables are properly connected to any new drives.
3 Check for large dust buildups on your CPU fan. If the fan isn't effectively cooling your CPU, the overheating CPU will cause your computer to power off. Carefully pick away large pieces of dust with your fingers, and then spray the CPU fan with a can of compressed air to remove the rest of the dust.
4 Reapply the heat sink compound between the CPU and heat sink if the computer continues to turn off unexpectedly. Heat sink compound is a pasty substance that fills the space between the heat sink and processor, which increases the heat sink's ability to absorb heat from the CPU. But worn heat sink compound won't properly redirect heat away from the CPU. Power down your computer, disconnect its power cables and open the case. Unplug the CPU fan's power cable from the motherboard, remove the heat sink and fan combination from the CPU, and then apply the heat sink compound to the CPU--refer to your product manuals for details on reapplying heat sink compound.
It is not the motherboard that is cooked it is the processor overheating to correct this problem you need to do the following
Remove the Heatsink from the CPU and re apply heatsink
compound to both the CPU and the heatsink then replace the heatsink onto
the CPU. the reason for the overheating and shutdown is that the
connection between the heatsink and the CPU has become "Aged" and no
longer transfers the heat like it should
try applying new cooling pest between cpu heatsink and cpu. Heat from cpu surface should be quickly transferred to heat sink. Either coolent problem or heatsink doesnot properly fit on cpu. But be carefull, you need an 'EXPERT' to do this, or you end up damaging everything.
Yes.... over heating can and will cause a system shutdown..
Download and install speedfan ( http://www.almico.com/sfdownload.php ) It will most likely tell you how hot things are really getting......
Depending on what cpu you have, you may have a thermal paste problem, you may need to remove the heatsink and re-apply heatsink thermal paste to the bottom of the heatsink and reseat ontop of the cpu. This will void any warranty if you PC still has any left.
I believe you have overheating problem Remove side of case and clean all fans including power supply one then clean and remove all fluff and dirt from Heat sink vanes. Then vacuum out case include all vent holes and behind power supply ones Then restart computer
