Toshiba Satellite A75-S1253, 1G Ram, 56G hard drive. Should I restore those dupe files??

Do you have other USB devices plugged in?

No, just when I put the card in the card slot, then when I plugged the little USB snake light in, each at diffeerent times. This morning, i powered up, then pushed in the PCI card, all worked OK until I took out the snake light, it froze, totally..

Thanx..dana

Ok, I missed this the first time I read your first post. What are you referring to as a PCI card?

Are you calling a USB hub which plugs into a USB port a PCI card?

No, it's a 6 in 1 photo card reader by San Disk . It's worked fine for a number of years No hubs or anything like that. Dana

A USB hub is a device that expands a single USB port into several so that there are more ports available to connect devices to a host system.

What is the model of this SanDisk

Have you tried the port without the card reader installed?

well, so far, so good...I've taken the light in and out w/o the reader, and no issues so far...I started thinking too, that maybe static was involved. I remember getting up to go to the drawer to get both reader and light, both times in bare feet, on a rug, sitting down on a fabric couch.We have forced hot air heat, and I'm in Boston, so it's dry air.......I got a snap last week from doing this....we'l;l see..thanx again for the help...Dana

The threshold for feeling pain from an electrostatic shock is about 3000V (Volts). A 10V electrostatic discharge is enough to kill integrated circuits. Walking across a carpet as you described can produce around 30,000V. Beginning to see the picture? :whistle:

You should discharge yourself before handling any electronics where the components are touchable, or where the case can conduct voltage to the components. You can do this by touching a grounded surface.

And yes, there will be a test later. :hysterical:

I hope this solves your problem. I'm sorry that it looks like your card reader is damaged, but at least now you know what has been causing this problem. :thumbup2:
