Hi,

I'm new to this forum, so perhaps that means I haven't been getting in to much trouble lately, and that's a good thing right?
Okay, here's the situation. I'm trying to connect my a scanner or graphic tablet to my PC and after a couple of minutes of normal situation, my PC freezes and starts rebooting!

It's no problem with my power supply (300W), no problem with software either (neatly installed before pluggin in devices)...

But... i did notice when i tried plugging the usb cable into a different port I got a electrical shock! So what's going on and how can I fix it?
Any help: GREATLY APPRECIATED!

cheers,
Simon

Hello SimonDD,

Welcome tohttp://www.pcguide.com/ubb/pcgubb.gif Forums!

Would you provide your system specs for us? And, any peripheral devices, USB, etc., that you have connected.

thanks for replying Whyzman,

I'm at work now, so I can't get to the details but i'll try to get all the specifics by tomorrow!
In the mean time, here's some general stuff

OS: Win98Se
RAM: 128Mb,
Processor: AMD Athlon 'Firebird' 750Mhz
Motherboard: got to check that again
USB: 2 ports on the motherboard (think USB 1.1)
Peripheral devices: tested with a scanner (some time ago) and
Nisis graphical tablet (now). I tried to disconnect as much of the peripherals, but the problem persisted. After a certain time a crash occurs.

I also checked the USB port status in the Windows Control Panel, but no problems were reported

So, I'll check for the motherboard and any other thing I can come up with.

untill tomorrow!,
cheers
Simon

USB ports are hot-swappable, so the are always "live", I would look for a cable problem if you got shocked plugging it in...could also be a bad port.

Random reboots are quite often power or heat related. If you're getting a shock...something might be awry with your power supply.

Are you monitoring the temps? Have you made sure that your heatsink is clear of any dust? You could pull the case and put a fan gently blowing on it and see if that cures the problem.

thanks for the suggestions,

I checked my motherboard, and found out it's a MSI K7 ver 1.0 motherboard. I removed the dust (there wasn't much) and I tried different cables. The only possibility left would be the ports themselves it seems. I was wondering if there is any logger or diagnostic tool that gives me info on power and temperature...

thanks,
Simon

A Good monitor for heat and power both is Mother Board Monitor (MBM5)
Available here

Unfortunately is only reports what the Voltages are on the mother board
and Not what is at the USB port
