usbwindows 7
For the past two days, whenever I plug in my USB mouse (which has been working for a long time, previously) into the laptop, my computer restarts! I tried changing mice, but the same thing happens.
I have 3 ports, usually, I try one port and the laser does not come on, then I try another one and the laser comes and and off, then I again take out and put it in any port and the damn thing just turns off the computer.
Specs: Windows 7 Ultimate 64-bit, 4GB RAM, Fujitsu 532ah i5 laptop
That black plastic thing is a contact support block that is a single integral piece (both arrows) that the contacts insert into. Black on your USB sockets, white in image below:
If you give the USB plug inserted into this socket a good sideways push, it can snap the contact support block (top arrow) out of the socket.
Once this happens, the port is destroyed. Even if you insert the USB plug in the proper direction, the contacts have no support to ensure full, proper contact.
At this point, you've got a few options.
If the sockets are installed on the motherboard, you will have to do a full motherboard replacement (expensive)
If the manufacturer planned on users abusing their equipment, they may install the sockets on a small sub-board, you will have to replace that sub-board (less expensive)
If you know someone who has the skill to unsolder the socket, they (after much disassembly) may be able to desolder and reinstall the sockets. More or less expensive, a 2009 laptop may be worth less than the repair expense.
I would examine how you use the cooler and how its plug mounts. The most likely cause is that you use the combination of laptop and cooler in such a way that you keep hitting the USB plug, causing too much stress on the socket.
It's common when using stick type USB devices, to hit one of them and due to the leverage from the case length, snap the support block out.
Cable plugs tend to be a lot shorter and are less likely to break this piece as you're less likely to catch them just right.
Did you attempt to go into Device Manager and remove all USB ports, devices, reboot and let Windows reinstall the drivers?
USB Devices Not Working Properly:
Press Windows Key + R and type "devmgmt.msc" in the Run dialog box to open Device Manager
When the Device Manager window opens, seek the USB device you're having problems with. It could be listed under Human Interface Devices as USB Input Device or if you don't see it there, expand "Universal Serial Bus controllers" to find the USB you're having an issue with.To find the one from the list for which you have an issue, you have to follow the trial and error method. That is, plug and remove the device and note the changes among the list of devices for Universal Serial Bus controllers. The entry which is appeared and then removed subsequently is the entry for issued device. Keep the device plugged in and right click over this entry, pick Properties.
In the device properties window shown below, switch to Details tab. Now click the drop-down menu for Property and select Device Instance Path. Note down the corresponding Value because we will need this value in further steps. By the way, this value is combination of three IDs; namely Vendor ID (VID), Product ID (PID), Instance ID.
Press Windows Key + R combination, type put "regedit" in Run dialog box and hit Enter to open the "Registry Editor".
Navigate here:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\<Device Instance Path>\Device Parameters
Substitute the Device Instance Path part (after USB) obtained from the step 3.
In the right pane of Device Parameters key look for the "DWORD" named EnhancedPowerManagementEnabled which must be showing its Value data as 1. Double click on the same to get this:
In the above shown box, change the Value data to 0. Click OK. You may now close the Registry Editor as well as Device Manager.
Reboot the machine to get fixed!

This sounds like it's a driver problem. Did you update anything lately? If you did, you may want to roll back your driver. If you hadn't updated anything before this started, then I would suggest maybe reinstalling the drivers, or getting a new one.
