I am trying to help with this rig. The issue is that, when trying to shut it down, all appears to go normally but one of two things will happen. It will either restart or the power LED will go amber with the CPU fan running at high speed. If I press and hold the power button, it powers down but restarts. This happens in both safe mode and in normal operation. Here are some system details.
This is a refurbed unit by Joy Systems with both the original product ID sticker and the Joy Systems refurb holographic sticker. Joy Systems seems to be a legitimate operation. There is a Dell service tag attached.
The CPU is a 3.0Gz P4 with 4 megs of RAM. The drive is a 500 gb Seagate SATA. The OS is Win XP Pro 32 bit.
Here's the kicker. This was purchased as a student's PC. The user appears to have upgraded or reinstalled the OS using their student version of XP Pro. I have their copy of this software and it appears to be legit with a PID code. The embedded PID code on the system is that which is on the student version plastic sleeve and not that on either of the unit's stickers.
There is evidence that this is not a clean install by the user though I received it with missing drivers. PTEDIT32 shows a hidden partition and there is a Dell/drivers folder. I was able, using the service tag #, find and install the missing drivers for the chipset, video display and Ethernet controller. But, the shutdown issue is said to have occurred prior to the installation of the student version of XP. This copy was only SP2 and I have upgraded to SP3. I did also download and update to the latest BIOS and set it to defaults.
All works well except that I cannot shut the darned thing down. This is one of the problems the user complained of. I have not suggested they take this up with Joy Systems yet but I may need to. I could probably image the system and see if I could try the factory recovery option but have no media but what might be on the hard drive.
Any ideas about the shutdown problem would be appreciated. Thanks in advance.
