    Is my PC about to Die USB connection keeps disconecting

    My PC is 6 years old now(longer then I have known my wife) and its started to have a USB error as any USB device like Printer/External Hard Drive keep disconecting when in use. The 2 Printer, Scanner and External Hard Drive are on a Powered USB Hub and USB 3 is by a PCIe Card with one slot connected to a USB 3 external HD with external Power. So its the onboard USB2 and card USB3 having the same problems!

    P35 mobo, E6750, 8GB RAM, 4 x 1TB or 2x2TB HD, 9800 graphics card, DVD

    I have tried all the usual options of changing cables, psu and drivers.

    Anything ELSE I should try?
    24/7 PC CoolerMaster CM690 + 7 fans(its HOT as HELL in Shanghai) Intel Xeon E3 1230 3.3-3.7Ghz, 2x8GB DDR3 1600 G-Skill, HD GT630 2GB, Scandisk Pro 256SSD 2x2TB Green, 2x 3TB WD Green Data Drives. HTPC Q8400, EP45 UD3L 4x1GB Gskill6400, 1xWD Black 640GB,2x2TB WD Green, 2xWD 1TB Blue(RAID1), Sapphire 4530 512MB,

    Computers have enabled people to make more mistakes faster than almost any invention in history, with the possible exception of tequila and hand guns.

    Considering your onboard USB, and the add-in USB card are having the same problems I would think this is more of a driver issue.

    You should eliminate every device off the USB (including the hub) next try adding devices one at a time. Add a device, do some testing, then add another if all is well.

    Also look for bad caps on your motherboard. Bad caps are a very common problem on older mobo, if you have them they can cause all sorts of weird issues.
