Hello Folks !
Here's my latest cause of neuro-hypertension !
I approach my CPU (an old P3 having an Intel 810 chipset with CD R/W, 512 MB Ram, 160 GB HDD, Floppy, USB controller) with noble intensions.
As I turn push the power-supply on-off switch, I hear a wierd, cracking sound and the next instant I realize that my lights are out ! The mains of my electricity fuse box trip ! I pull the circuit breaker back up and try to repeat the now nerve-wreking task of turning on my CPU. It's dead ! It won't respond to the switch: no leds, no fans, no motors run ! My monitor which recieves its supply from the CPU (via the mains cable) turns on !
Next, I open the CPU with an attempt to find smoke, melting plastic. Fortunately (or unfortunately), there's no trace/smell of smoke. Now I try and hunt for the fuse, but alas, the damn PCB is so cluttered, that I can't find it.
So now I'm trying to trouble shoot whether it's a repairable problem (a simple task of changing the fuse somewhere) or whether my PSU has gone dead !
Needless to say, this is the first time, I've encountered such a problem and have no clue how to proceed. I shall lay my hands to a DVM to rule out the PSU...but first I need to buy a DVM ! (i've moved out)
Can someone throw some time to solve this mystery ?
