HP All in One Shuts down

A customer gave us a HP TouchSmart PC 320 All in One to repair - the system will turn on for about 2 mins and then shuts off, then when trying to restart, maybe runs for 15 seconds and shuts off.  I have tried to run a diagnostic on it but cannot get thru that.  I have also tried to run a check for malware but same problem.  Tried to change msconfig - same thing.  I have read about trying a different power supply but have not had one so didnt do that.  The system is running at 100% when I get into Windows - also tried safe mode

AIO systems are a devil to work on.  The space is limited, the power supplies are always non-standard, and often there isn't a fan so cooling is a problem.

Acceptable temperatures seen in the BIOS setup screens don't reflect what happens once Windows starts running.  The system is not under much load when in BIOS setup.  Get one of the many different programs for temperature monitoring, have it start automatically at startup and log its temperature measurements to a file.  It does no good to have the monitoring program in the system if it must be started by a user but the system fails soon after startup.

Check the cooling vents.  If the owner has pets it's likely that the vents are obstructed with hair and lint.  Pick it out with a dental pick.  Don't be tempted to use canned air, as this usually makes things worse by forcing dirt plugs further inside.  If the system has a fan, check to confirm it's actually moving air.  Fans in this high-heat environment with less than optimal cooling have a short lifetime.  

If it's not a cooling problem then it's likely to be a power supply problem.  Given that this system uses a non-standard supply and that the supply is external, the owner should have a spare power supply on the shelf ready for when the old one fails ... and it will; there's no cooling in that solid-case supply.  They can be readily found on fleabay; link below.

The fact that in first time it last longer and then shuts down almost immediately, might indicate that is a hardware problem - it seems that the CPU is overheating.

I would agree with the overheating comment.  If you can get into the BIOS there is likely a temperature monitor.  If it shows too high of a temp then I would be checking the CPU fan to confirm that it is spinning and then properly reseat the heat dissipator on it.

Hello,

According to what you indicate, it is a hardware failure, it makes a diagnosis to validate that it may be causing the problem.

It can be from power source or CPU, you see alarms at the computer level.

I remain attentive to your comments.

disconnect all devices, eg cd drive and if possible strip down the ram to 1 stick
test with minimum connected

I pulled the system apart and took the fan and put in on fins of the heatsink and has not quit for hours.  Yes this is not a long term solution but at least I can retrieve the data.

that seems to indicate it is overheating
can you remove the heatsink, and renew the heatpaste?
install speedfan to monitor temps also :

Hello,

Run hp diagnostic tools to validate if the problem is hardware or software.
