I have a HP D530 thin client PC with only a sound card changing it from the standard spec.

P4 2.5gHZ
512Mb RAM
180Gb SATA2 hdd
DVD/RW Rom

Over the past couple of days the machine has just been switching off at random moments, but not exactly switching off, the monitor will switch off and the power to the PC will remain on, but I will have to manually switch it off and back on to get it working again.
I tested to see if it was the monitor by playing music, once it did turn off the music stopped so there is something the matter other than that.

When it does switch off, the HDD led turns off, but the power led stays on, my infrared mouse stays on also.

Anyone got any ideas? It has only just started happening, I have tried another HDD and same thing occured. Could it be the main board and the VGA port?

Temp readings on Everest read:
Tsystem 37oC
Taux 45oC
(Whatever they mean!)

Speedfan read them at:
CPU -128oC
Local 41oC
Remote 2 49oC
HD0 52oC

Have you noticed a temperature increase?

The speedfan readings, if true, are very high for the chip unless it is a mobile.
 
The thermal paste on the CPU could be gone.

I had a venice that was running at 90deg idle, reason was a drop of sweat got onto the AS5 when I was installing the HSF, over a week it degraded the paste until it was useless.

What I would try first personally, one of the easier things to do unless its held on with epoxy.
 
another thing - i expect the power supply fan is sticking or not working. check this out as well. the company i work buys loads of these machines and we have had a few psu failing lately - fan faults. the machines will basically be up and down like a yo yo.

also do u notice any beep codes? lets us know
 
This is off the wall a bit, but I have had the same thing recently and it turned out to be msn messenger live 8.0. Every now and again it would go to 99% and then lock the machine. Machine would still be running and if you were there at the time monitor was still on, obviously after monitor timeout monitor would go off and would not resume but machine was still running.

Used google and found a few tricks about clearing caches etc for it and it now seems fine.

Long shot I know but problem sounds identical.
 
if you are running 2k then disable HT, also i know theres a bios update for that series that alows you to turn up the fan speed.

Also make sure that you have clipped any power cable ties, sometimes they are too tight on the cables when they expand and get hot.
