Windows 7: pc not starting up normal and freezes 15 min after booting up

pc not starting up normal and freezes 15 min after booting up

i have compaq presario sr1630nx and i have an issue that started after i opened the case and used my compressor to blow the dust out of it its not the first time ive done this like 4 times to be exact. my machines issue starts when i turn it on the fans go on but the cpu fan runs the loudest and it displays nothing other attempts it turns on normal but still nothing on the display. after idk the twentieth attempt of turning on and off it finally boots up normally, but i cant do nothing major like go on the web to long because it freezes right away. i could listen to music but it will eventually freeze after fifteen minutes or the display will turn to an orange or blue screen. the pc does have some upgrades like a graphics card for two dvi inputs and power supply which were done about a year ago. if anything i think it might be the mother board which can be replaced but idk can anyone spread some knowledge and give their opinion of what this issue might be?

When you blow dust out, you want to do so in the following sequence.
  1. Shut down and turn off the computer
  2. unplug all power sources from the case
  3. hold down the power button for 30 seconds to close the circuit and drain all power from components
  4. remove the case
  5. blow out dust
  6. replace case
  7. plug power supplies back into the computer
  8. turn the computer on

If you do not follow the above steps, you risk damaging components. Also, if you are using a compressor at full pressure, you may damage components by the pressure applied to them. It is better to use a compressor designed for electronics or change the pressure output so it is not too high for the compressor you use.

All that being said, can you follow the to provide us with additional logs to diagnose whether it is a Windows related issue or hardware issue? I realize you are not having a blue screen crash, but those instructions produce other log files that are useful for troubleshooting steps.
