Sorry to ask a question in my first post.
Me and a friend of mine bought a new pc with exactly the same components.
Mainboard: Asus A7V8X-X
CPU: AMD Athlon XP 2500+ Barton
VGA card: Asus FX 5600 V9560/TD
RAM: 512 DDR PC3200
Everything worked fine. But then we both installed a different Logitech wireless keyboard and mouse. Now when the power is turned on, the system doesn’t go any further than the screen where you can enter the bios. If you press the reset button then, the system starts normally. This happens every time and on both pc’s. Can somebody help me with this ?
