I have an error that i have been unable to diagnose myself.
ill refer to it as the 50/50 error
50 % of the time my pc boots no problem everything is great . and with no changes to system setting or any other aspect of the computer....
the other 50% of the time my pc just hangs in 1 of 3 places
1. my pc doesnt post and says on the screening searching for usb devices ( i have an external hard drive plugged in and an external dvd burner plugged in ) with them unplugged it never has that error.
2. My pc boots to the windows screen with the blue scrolling bar and sits there ive counted how many times tha bar goes by as if it matters and lose count after 100 times ( usually boots after 5 )
3. or i get a 2 beep code (parity circuit failure) and pc will boot fine but mouse and keyboard dont work (logitech wireless combo).
My thought is its the mother board any ideas ?
