You might have a broken or dirty CPU fan. The CPU heat sink fan is responsible to cool down your CPU while it is on. If it is broken or stuck(dirty), then your machine will power off automatically preventing CPU damage or worse-case-scenario:FIRE caused by "burnout".

Your CPU heat sink might not be mounted on your LT properly. Also causing overheating; thus shutting down.

Its a laptop right ? Right! Another thing you could try is to unplug the battery, and let it run from AC power only and see if it makes any difference.

Desktop shut down in few seconds after getting display


Good day,
The problem you describe is probably due to a faulty power supply.
The four pin connector which you unplugged supplies power to the CPU, which means you will not be able to get a display with it plugged out, as there will be no power to your CPU.
The fact that the PC does not shut down when removing the 4 pin connector strengthens the evidence that your power supply is faulty. By removing the 4 pin connector you are reducing the power required from the power supply to the point where it is not 'overloaded' enough to switch off.
You can test this by plugging in the 4 pin CPU power connector, then unplugging something else, such as the DVD writer.
Then switch on your PC and see if it still shuts down.
If it remains on then the cause of your problem is definitely the power supply.
Replace the power supply and make sure it has a wattage rating of 400 watts or more. These power supplies are relatively cheap, and should be available at your local PC store for about $15.
Best wishes,
Graeme.

To identify a bad capacitor you will need to open your computer case and locate the capacitors on your motherboard. A bad capacitor may exhibit swelling at the top or the base of the capacitor or it may sit at an awkward angle with the motherboard, so compare the various capacitors in your computer in terms of and placement. Additionally, a bad capacitor may have a funny smell or it may have a brownish residue leaking from the top or the base. b> Prevention b> Manufacturers claim that capacitors may go bad because a computer is not receiving enough power from a power supply, because of an overclocked processor or because a computer is operating in an environment with too much heat or humidity. However, some capacitors prematurely fail due to faulty work on the part of the manufacturer. If you have a bad capacitor be sure to do research as to the lifespan of other products made by your manufacturer.

HP Desktop power up problem


Bad ram probably, units do that all the time at my job. Most of the time, it is the power supply that does not have enough power to invest into all hardware that makes your pc. even if you had a 400watts power supply, the next time you are buying a power supply you should do some kind of upgrade. 600 watts or more. If you have a high end graphics card then you are indeed in need of a new power supply. also check your cpu, its fan, check if it still seated properly, if there still paste on top of it to hel cooling it down, and protect it from statics. if you added new hardware, remove them and keep checking if it is working. To do manual diags, you need to take the unit apart. I would start by removing rams first, and check ram one by one, then hdd, then disconnect other components until i find the actual part. I am sure it is your powersupply, worst case scenario is you mobo is gone.(but it powers up and shutdown after all so let us hope you don't have a dead motherboard." and remove the dust please, dusty units do not run properly.

This happens because your CPU is overheating, open your PC and blow any dust off the openings and CPU/Power supply fans, if you think one of the fans is not working... replace it.
