SCSI drive shorting

[virtualranger]

Sorry, bit of a long post.
Spec:
Fujitsu MAJ3182 18.2 Gb (68 pin) SCSI disk.
Tekram DC-390U2W (PCI Card) SCSI Controller
Soltek SL-75KAV mobo
Nvidia Geforce 2

On boot there was blank screen, horrible sparking noise and burning smell. Took the back off and restarted - saw sparks coming from the underside of the SCSI disk. Powered down. Removed disk and could see scorch marks on one of the chips.

Disk still under warranty and the manufactures (Digital Networks UK.) sent a new disk the same day.

Put in new SCSI disk but on boot there was no video. Tested vga card - card blown, so took video card from spare PC.

Now when I boot, I get usual VGA and mobo bios bios stuff but then SCSI controler bios no longer appears, it just says that there is 'no bootable device found' (which would be true as the disk has no OS on it). It gives me no option to go into the controller's bios settings as it used to.

Boot order is Floppy, SCSI, HD1. So it then boots happily from standard IDE disk I put in there. The SCSI controller is recognised in windows device manager (it has been assigned an IRQ etc) but there is no SCSI disk present in device manager. I ran the controller's dos utils program from floppy and it said it cant find controller. Weird.

Questions:
1) What causes a disk to suddenly short out like that?
2)Could the disk shorting cause the video card to blow? (the mobo and cpu both seem fine)
2)Is it likely that my my controller has blown as well?

Hope someone can shed some light on this.


Cheers,
Jamie

Stuff happens. I can only tell you it is not the first.
Within the chips there are conductors thousants of an inch apart. If a current path develops between power traces you get heat and eventual destruction. Eventual as measured in thousants of a second.

Yes , it can take out SCSI controller first, then through the bus to the Video, CPU , Memory, and anything else connected to the M/B.

And anything else that was resident at the time of the failure is at risk, along with anything new you put in. Ed Fair
