Hi guys, first post on this site, hope u can help.

This has been doing my nut for a few weeks now. I been getting what i think is some kinda usb quirk.. on desktop/in game [lesser extent], i get mouse/joystick (usb?) freeze that may last between 1-5 secs. these occur at varying times, sometimes i could go days without it, other times, like today, its happening every 5-10 mins or so.

If im on desktop, i can unfreeze the mouse by hitting 'esc', where as in game, i have no option but to ride it out.. if im playing say battlefield2, i could be in a chopper... without warning, my cyborg evo ceases to respond, the chopper lists and inevitably crashes unless life returns in time for me to make some manner of recovery manoever

My pc isnt that old (less than 6 months), ive built a few before, this one is otherwise very stable and gives me no issues. all drivers are latest etc..

Spec:
AMD64 3500
Asus A8N SLI delux
120bg/40gb ata's
2gb ram
XPsp2 fully up to date
bfg 7800gt
Audigy2 zs

in case there are any known issues, ill let u know my peripherals:

Nostromo Speedpad n52
Saitek Eclipse keyboard
Logitec g5 mouse
Saitek Cyborg Evo.

Any help, or ideas greatly received.
