Solve : Computer won't boot and making funny noises?

1.	Solve : Computer won't boot and making funny noises?
Answer» Hi,am on my laptop at the moment my home computer started up this morning fine but then froze. I couldn't do anything with it so switched it off at the BACK and RESTARTED it. Now all the lights are flashing as normal and it sounds right except for a high pitched INTERMITTENT beep which is there all the time and the monitor says no signal. Any ideas as to what is happening Thanks Paula Check your monitor connection at the rear of tower,make sure it is TIGHT. Maybe even unplug it and then reinstall. If not may be video card, is it onboard or pci/agp?
