USB ports KILL all thumb drives and devices

[123malstrom]

something is killing my thumb drives. My Frankenstein computer with a new /usb MOBO has been working for months without fail............. suddenly I have lost four USB memory stick a card reader and a usb hub . ( 2 new usb sticks too.) Its using a extension cable from the rear usb port of a 2.0 port . ( cuse the front ports don't work) I don't dare try to
test with any more sticks ... has anyone had this problem before? I am buying a usb voltage tester but what are your thoughts? has this happened commonly?

Best guess is that cable hates you, has it killed on plugged directly into the board?

Well yes that one cable has been a commonality now that you point it out. Yes it is a rear USB port directly to the I/O plate, ,.but now I notice that the USB cable design fits two other ports marked Sata and firewire. I wonder if I got plugged in there and those ports carry a different voltage.

Download HWMonitor and tell us what your 5v rails actual voltage is. It could be a failing PSU delivering too much voltage on the 5v rail.

So here is a screen shot of my voltage readout from Hw monitor. I did receive my Usb port tester from hong kong. It measured the same voltage o all usb ports when plugged into the ports.


It measured 5.13 to 5.17 V and would fluctuate from those top to bottom values. I have ........

to ask is this really enough to cause damage to a USb thumb drive? I am measuring 5.25 on another computer that I trust.

This suspect computer has a brand new Lepr 500 power supply added 6months ago. If its not a voltage problem what 's killing my usbs and equipment.

Should be fine, I think 5% variance is acceptable limit.

You ever try one without the cable?

 

[123malstrom]

yes I lost a external Card reader and also a USB hub and 2 usbs connected to it. I changed the cable and then killed the usb there. That was when I could read the USB power output as stated in the above post at 5.13 to 5.17. The usb port will function my keyboard and mouse properly. But I think I've had it with this Ebay board. Its time to replace/ sell it.

Did you put the standoffs in before you installed the mobo? If you didnt it'll short everything

 

[123malstrom]

Hmmmm very good question Paul I will have to shut down and check. I would guess that I would blow the whole board if that were the case.

The original case and HP tower pavilion has what I call volcano mounts built right into the Case. If I use the gigabyte board in this case and spacers the I/O plate will not line up with the case exit. Like the HP board I did not use spacers and have had no trouble in six months of use. If I did I would have destroyed the board immediately. Do you have another view or experience on case spacers ?
