This sounds like it could be an overheating issue. Some manufacturers use a cheap thermal paste on their processors. If you are dealing with a computer this should be an easy fix but if you are dealing with a laptop then it is much more involved. Go to Youtube and research replacing or removing heat sink. You wont be replacing the heat sink but the procedure is the same except you will need to clean the old paste off your heat sink before you apply more. Don't go crazy with the paste, a little goes a long way, all you are doing with the thermal paste is ensuring full contact between the processor and the heat sink with no air gaps.

Powers up but HDD just clicks. Tried several things...

if the hard drive clicks, there's either a serious problem with the hard drive itself, but since you already tested with a drive that is sure to work, it has to be the motherboard. the other post you read, has probably nothing to do with your own problem. try reinstalling your system board's drivers or replace the system board if unsuccessful

Power supply not staying on

Sounds like when cleaning your computer, you have also cleaned your processors heat sink and fan. right.

if you have done this then there in lies problem.
either your heat sink is not placed correctly
or you forgot to apply a new thermal interface material. because once you remove the heat sink the interface material is of no use. you must apply a new one. and check that you have placed the heat sink correctly and firmly.

Do you have any idea why a laptop would power up all the way to Windows and then unexpectedly shut off without powering down? It is still plugged in. The battery is fully charged.

Maybe a heat issue. I had a P4 system once that would do that exact same thing. I cleaned the cpu cooler and fans and added new heat sink paste between the heat sink and cpu. No problems after that. Let me know if this helps.

Dell Dimension E510 Powers Up, Then Crashes

It's the processor or power supply. I cant be sure of which without checking it.

Check the fan over the processor heat sink to make sure its working cause it could mean that the processor is overheating If the fan turns and then it cuts off this could meant that the processor is dead. or the bios is corrupted. Try flashing the bios, there is a battery on the main boad, remove it. unplug the system first... when the battery is out press and hold the power button for 10 seconds then release. put the battery back in and try to turn it on..

If that fails then try a new power supply or one from another system to to check if the power supply is fine. YOu can aslo bridge the green and any black wire from the power supply's mainboard connector to see if the power supply runs. If all this fails then you may need to replace your processor,, I';d also recommend changing the power supply as well.

This could be a number of different problems that causes the irregular shut down. It could be the power supply, battery, memory, processor, fan, heat sink, or motherboard. Try these in this order. Check the power supply with an ohm meter for the proper output. Remove the battery and run on power supply only. Remove the memory, and try running with one chip then the other. If the machine seems hot when shutting down, clean the fan and heat sink, also remove the processor, blow it off with air and seat it back in properly. Check all connections on the motherboard. If at this point the problem sill persists, then it's a significant problem with the motherboard or a motherboard component, and you should take it in for a professional diagnosis.
