OK try this for a test,
I agree you may have a problem with the ram leaking. Have you changed any hardware configurations? Have you recently installed new ram? If so Is it the same MFG, Part Number and Nanao Seconds the same including the lot number? Was it all purchased together out of the same box?
If you add ram I suggest you purchase all new ram do not add to existing ram. Could cause problems.
Start the computer, Let it boot to the windows operating system.
Check your system resources. you should be about 86 percent free or better.
Start a program, how ever do not fly or run the program.
OK minimize the program, Check your system resources and see how much it dropped.
If you dropped very much you probably have a bad stick of ram.
Try pulling out one stick of ram and re run the test, remove that stick of ram and install the second stick of ram and run the test.
install both sticks into diffrent slots and run the test.
Be sure and take a marker and write number one A on the first stick of ram for the first slot (call that slot A), 2B second stick of ram 2nd slot (call that B). That way you will no what your original configuration was on the ram and slots.
When it comes to hardware often it is a process of ilimination.
If you are running a Pentium 4 board you will have to have blanks to install where the ram goes that you pull out. You can get these at any computer place that does repair. They should be free, they come with new boards and when you install a new board you have to remove the approrpiate number.
If that doesnt work Try increasing the memory stored on the hard drive. Should be 8 percent of the amount of ram you have,
The only other thing I could think of, but probably not would be the video card? Or the Mother Board has a weak thread from heat.
Have you cleaned the computer and fans with Oxygen? What is the internal case tempreture? Should be under 98 F or 38 Celsius
Is your power adequate and working properly?
Is cooling your problem?
Are all your fans working properly?
Power could be the problem?
Check your power supply, add up the number of watts reguired if every thing in the computer was running at the same time, Then you will need a minimum of another 45 percent over that number.
If you are running a Pentium 4 you have to have a minimum of 12 amps to the processor.
