If your laptop shows a blue or purple screen at boot-up and then flashes off it may have suffered some kind of hardware failure. Try and see if you can make a note of the error message on the screen so you can explain to IT support although it may be too quick. You can try pressing F8 repeatedly at power-on and choose SAFE MODE or LAST KNOWN GOOD CONFIGURATION to see if the laptop will boot. Otherwise phone IT support on (0118) 214 0857
