Just registered to these boards wondering if anyone could help me. When i turn my computer on the screen dosent go live and the onboard bios beeps high-low 3 times. This is after my computer crashed the other day and black and red dotted lines appeared on my screen. I turned the pc off and then cleaned the fans as i thought it may be over heating. When i tried to turn the computer back on all i got was what is written above. Im not great with computers so wondering if someone could help me with this please.
