That is usually an indication of a hardware failure.
The pattern of the beeps is intended to indicat e which hardware.
If you get not monitor display of any type, the first thing to try [with the power OFF, including unplugging the power supply to remove the 5 volt standby voltage] then remove the video card and plug it back in.
Another beep could be loss of memory [RAM].
Your mobo manual may give the beep codes [what beep pattern = what hardware problem] or a visit to the website of the mobo mfr should provide them.
my pc wont start, all it does is make error sounds (bleeping), i noticed before this thing happened, something funny happened to my desktop icons. after i have shutdown and rebooted, my pc wont start anymore. even the monitor wont start, the led indicator in my monitor just blinks in orange (rather than the usual steady green light when it is turned on). i cant even access the bios because all it shows is a blank screen and a repeating bleeping sound. anyone have any ideas how i can solve this problem? thank you
