Problem with Saitek X45 controls

[Robban_Sweden]

Hi!

I have a very annoying problem with my Saitek X45 throttle and joystick. It stoppes responding all the sudden, and it can happen at anytime.
Sometimes I get all the way to the approach for landing and sometimes I don't even get as far as taxiing before it stoppes working.
When they stop working the movement of the joystick or any type of action of the controls is either delayed by several seconds or it doesn't respond at all.
If I disconnect the controls and plug it in again it works immediately afterwards but the problem is back again after various time.
I use Flight Simulator 2004 and run it on Windows XP.

Any ideas?

I have a computer that does that with the keyboard. I am wondering if it is a problem with the +5 volts that runs the USB ports. Be it a bad motherboard or a bad power supply.

Could it be the power supply?
I'm not very good with computers, but the problem has actually increased since I changed my graphics card from a GeForce 6600GT to a GeForce 7800GTX.
I have a 350W power supply.
