A system service exception is where a bit of hardware made a request of the cpu for resources.
But the cpu could not perform the task, due to it being busy doing other things, or the service was already in use.
And resulted in a time out error being a System service exception it took to long to process the request.
Possible causes lack of memory, More than one piece of hardware using the same IRQ request for hardware, software calls to the Cpu. Basically the line is busy,could not complete the request within a set amount of time expected.
If you have multiple bit`s of hardware in the system that wish to use the same IRQ, this conflict is often the cause of a system service exception error.
The fix is to check all of the hardware through device manager, see how many devices are trying to use the same Irq number and changing the hardware device to use a different Irq request number to the cpu.
Often you can resolve the problem by turning off hardware devices in the motherboards bios that you do not use.
Examples of this are: serial ports,Lpt or printer ports.
Midi devices. IDE options if using Sata and the board has the ability to support, or has an IDE 40 pin interface on the motherboard.
PS2 mouse and key board ports, if using usb keyboard and mouse.
Floppy drive controllers, no one uses them turn it off.
That will free IRQ numbers for other devices, and can stop hardware devices from conflicting with the same IRQ chosen to talk to the cpu over it`s bus. In most cases it fixes the problem.
