whenever i play games on my computer, after a few seconds into the game, everything that's connected via USB (my mouse and speakers) will lose contact with my computer and simply stop working...

it has nothing to do with using up too many resources, i think, because when i run other programmes which cause CPU usage to hit 100%, no such thing happens...

and nothing to do with the newer games requiring more RAM to run either, cos even the older games which used to be fine have the same problem too!

anyone knows what's the problem and how to solve it?

Anyway, here's some description of my comp:
*Microsoft Windows XP Pro v2002 SP2
*Intel Pentium III Processor 501Hz 128MB of RAM
*NVIDIA GeForce2 MX/MX 400
*A4 Tech Optical mouse (with wire)
*Creative Soundblaster

Thanks in advance!! :)

It could be a power supply problem. The game cranks up, the CPU draws a heavy load from the PSU, and suddenly your USB devices are undervolted.

I can't use my internet if my CPU is overclocked for that reason too :frown:

Your speakers stop working, and they're powered by USB but get their sound from the Soundblaster, correct? If that's the case, it's not a data error, but a power problem. The response that it might be a power supply problem sounds most likely.

You could get a powered USB hub, that might solve the problem. You could also read the power consumption on each device and add them up. It's usually printed on there somewhere - the USB mouse I'm using now draws 100mA. You should assume that either each port or each grouped pair of ports has a maximum total current supply of 500mA. (so if I plugged 6 mice into a USB hub for whatever reason, the port would probably stop working.)

(edit: just to be sure, by "powered hub" I mean one that has a separate power supply that goes in a wall jack, not one that's powered by the port.)<P ID="edit"><FONT SIZE=-1><EM>Edited by grafixmonkey on 11/30/04 11:05 PM.</EM></FONT></P>

BTW, your USB powered speakers (bad idea) might be overdrawing the entire USB bus no matter how good the supply is. I'd try gaming without it and see if the problem goes away (you can use headphones for the time).

I have heard of this USB disconnect before it is a virus or Trojan not sure exactly what one it is but an XP machine makes the Ding-Dong noises when hooking up USB inputs as they can be plugged and unplugged hot.

Anyhow the few guys that are having difficulty with this are online gamers and they get the germ from online probably a Mouse hack designed to screw up USB mouse input but effects all USB connected.

None of the virus scanning we ran including all the other crap Spy Bot and Ad-Aware or any of those progys ever found the problem.

The fix is easy simply reload your Motherboard Chipset drivers and it should fix the problem.

If your XP reinstall DirectX9.0c and update at the MS website.

Port 137 is a UDP port used by MS for things such as Printer interface and other connection sharing. Many game server applications come through on a main Port number like 27016 for example but tag port 137 onto that port giving unrestricted access to hackers into your P.C.

After you get it all fixed for peace of mind even if you do not game online set a fire wall rule to allow OUT only on port 137. You wont get hit back in on it and your printer will still work :wink:

*Note Port 135,137,139 and Port 445 should all be set to allow OUT only as they share the same back door holes. They are not closed by any MS patch either. Not even XP Service Pack 2 fixes this problem.
