Hi guys, I have a problem my usb ports on top of my PC case have been having this issue of frying anything connected it started when one day, I connected a 4GB flash disk and was shocked to see sparks, after the sparks the PC went off almost immediately I removed the flash disk quickly and swithed on the the PC I opened the program event viewer at the start menu and then events then administrative events it displayed critical kernel power so therefore I closed the application then reconnected the flash disk it had a bright red led which to me was a, sign of life but on desktop it displayed malfunction windows does not recognize the device connected I reconnected it many times I tried two different PC's but still the same thing I therefore pronounce it dead. Please help!!!!!!
Many people would support the view that an electrical device that sparks etc is a hazard.
It sounds like a Earth/Grounding problem, change your power cable and have your electrical outlet/extension cable checked for faulty earth wiring. If it is a faulty earth problem you could be at risk of electrical shock or death.
