Belatucadrus Posted May 8, 2009 Report Share Posted May 8, 2009 Remote diagnosis of hardware problems is notoriously difficult to do well, here however are the three most obvious things :-1) Overheating, check the cooler fan on the CPU is working, if necessary replace it.2) Power Supply Unit aka PSU on its way out. Unfortunately difficult to test the theory without replacing it.3) Hard drive problems, usually accompanied by unfortunate grinding noises. Ensure you've backed up all important data as you may be left hanging if it caves completely. Quote Link to comment Share on other sites More sharing options...
ktc13 Posted May 8, 2009 Author Report Share Posted May 8, 2009 thanks for that the fan is working ok and there has not been any funny noises from the hard drive so maybe i will change the power supply to see if that works i have an old one from a computer i used to have do you think that would be ok Quote Link to comment Share on other sites More sharing options...
Boris Posted May 8, 2009 Report Share Posted May 8, 2009 i have an old one from a computer i used to have do you think that would be okPossibly not - it depends on the wattage it provides.Read this :-http://en.wikipedia.org/wiki/Computer_power_supply Quote Link to comment Share on other sites More sharing options...
Dencandy Posted May 9, 2009 Report Share Posted May 9, 2009 Yes, it's almost certainly a hardware problem. If it's a software problem the computer usually re-starts after crashing. Quote Link to comment Share on other sites More sharing options...
demon Posted May 17, 2009 Report Share Posted May 17, 2009 I would check the RAM. Did you change the RAM recently? Quote Link to comment Share on other sites More sharing options...

Dencandy Posted May 21, 2009 Report Share Posted May 21, 2009 I think you are going to have to take it to a computer technician. Quote Link to comment Share on other sites More sharing options...
-pops- Posted May 21, 2009 Report Share Posted May 21, 2009 Check that all vents and grills are clear of dust and fluff so that there is a good airflow through the machine.Also check that there aren't deposits of dust on the fins of the CPU heatsink (or anywhere else). I've just fixed a machine which similar self-switching off problems it was due entirely to sticky deposits of grime on the heatsink and pet hair impeding the airflow.
