Solve : Intermittent shutdown when plugging in to USB post? |
|
Answer» I have Windows7 Ultimate - 32 bit for my OS. Every so often my computer will shut down when I insert a thumb drive or other device into any USB port. It occurs maybe once every 5 plug ins, and it doesn't matter which device I'm using. Sounds like a bad port to me... Is it just the one ? ? I have 2 USB ports on the front. Both have the same issue, but it is only an intermittent problem.With most big box manuf. there are issues with the front ports being underpowered... Use the rear ports when possible and/or connect an addon powered USB hub would be the easiest solution.Quote from: patio on March 11, 2010, 03:16:08 PM With most big box manuf. there are issues with the front ports being underpowered... Thanks for the tips. SOMETHING to definitely consider. When it shuts down does it just suddenly switch off? Sounds like either faulty hardware or software. I'd rule out software first really, check that all drivers are up-to-date and make sure there aren't any USB or general updates on the Manufacturer's support site for your PC.Yep, when it acts up, the computer just shuts off. All drivers are up to date.Quote from: earlk on March 09, 2010, 08:56:40 AM I have Windows7 Ultimate - 32 bit for my OS.

First, you said "any USB port", but later you refer to the "2 USB ports on the front". Does this happen with ports on back, also?Sounds like the front header is SHORTING out...i wouldn't use it personally...Quote from: soybean on March 13, 2010, 11:03:07 AM First, you said "any USB port", but later you refer to the "2 USB ports on the front". Does this happen with ports on back, also? Thanks for catching me on that. The ports in the back are not a problem... they have my printer, scanner and keyboard (always plugged in). The two at the front is where I will plug in a card reader/camera, thumb drive or a phono unit. Any device into either of the 2 ports at the front will cause the problem. Again, most of the time there is no issue. Very intermittent.I have the same problem with my tower PC running Win XP. In my case, the computer restarts rather than just shutdown. It's as though I had hit reset button on front. Based on observation, it seems to be more likely to happen when humidity is low. In other words, it seems as though the front USB ports have extreme sensitivity to the slightest electrical contact when the humidity is low and the chance of static electricity being generated by walking across the carpeted FLOOR is present. So, I usually, although not always, avoid using the front ports. If you still have unused ports on back, a USB extension cord is a way to maintain the convenience of having access to them up front. Here's one: Nippon Labs Beige 3 ft. USB cable A/Male to A/Female extension USB cable Model USB-3-MF . If you don't have any more open ports on back without disconnecting a device you normally leave connected, additional ports can be added by installing a PCI USB card, such as ones listed here. I had a similar problem, but with Windows XP. About two months ago I was restoring a friend's computer. It was an older Gateway desktop. Turned out it was a driver issue. I used the driver that Microsoft provided through Windows Update instead of the driver that came on the Gateway driver disc. When I restored the system for the second time, I used the Gateway driver disc first, then applied updates from Windows Update and never had a problem. For what it's worth, it was all six ports - 4 on the back and 2 in front - that caused the issue. If I plugged in anything besides a keyboard and mouse, the computer just shut down immediately as if I pulled the plug. You might try getting a powered USB hub for < $30 and plug it into one of the good read USB ports. Otherwise, if it is a new PURCHASE, I would return it or tell the shop where you got it to fix it. If you still have a warranty, they should cover it. They should search for the fix for you since you are the customer. Good luck! Thanks guys, I'll most likely take it back to the shop as the 'puter is new.Quote from: soybean on March 13, 2010, 12:59:36 PM It's as though I had hit reset button on front. I haven't seen a reset button in years... do they still feel the same, that good ol' feeling of giving up and trashing Windows for Workgroups when it's really just got up and gone to the shops for some of Millie's cookies. |
