I have an old PC belonging to the IBM Netvista series. Even a few days ago, it was working fine. Today, however, when I turned it on, a loud crackling noise occured, and then it turned out to be dead: pressing the power button seems to do nothing.

 

I have a few questions:

  1. I'm assuming that either the SMPS or the mobo has shorted, however, how should I get to detect which one is the culprit?

  2. Could the HDD have been damaged when it conked out? (I have some rather important data on it that I didn't back up, and turned it on for this purpose when all this happened. The irony.)

Please excuse my ignorance and many thanks in advance.

Hi

 

Your SMPS is probably dead. Yes, there is a chance for Motherboardto be be faulty (due to the power spike from SMPS when it shorted ). You can do a basic SMPS diagnostic by shorting the green wire with any of the black wires. While doing so make sure to remove all connections to the motherboard and peripherals. If the FAN started to spin, you will get an idea whether it is completely dead or not.

 

 

 

To check your HDD and motherboard, there is no short ways. You should connect a good working SMPS and check if  the system boot fine.

(I have some rather important data on it

First consideration is retrieving your data. Pull out the hard drive and slave it to another computer (if it's a SATA there is no need to set to slave) and check that you can access your data. If you cannot, post back. I suggest not doing any additional troubleshooting on the computer until you back up your data.
