"What to do when beep codes occur"
The only bios brand I know of that produces a continuous beep or a continuous beep pattern is an Award bios, or a brand name bios version based on an Award bios.
"Beep codes for Award bios
Most Award post codes are displayed to screen. If a beep code occurs the problem is likely occurring before the system can display video (check the video card or memory).
NOTE: The following codes can vary depending on BIOS version.
1 short beep - POST process completed successfully - normal startup
1 long beep followed by 2 or 3 short beeps - Unable to initialize video (to display the post code)
Continuous beeping without pause - Serious system related issue such as CPU overheating
Other beep conditions - Memory errors."
In my own experience.....
....a pattern of beeps that indicate no ram is installed, or a ram problem.
E.g. for an Award bios or a bios based on one, that's often a beep of about a half second, silence for a half second, a beep of about a half second, silence for a half second, continuously.
Which were you hearing - the never ending beep or the continuous beep pattern ?
If there is nothing else wrong, when you remove all the ram, you get no video but you hear the beep pattern.
If you're hearing a continuous beep that never stops, then, since you have changed mboards, assuming there's nothing wrong with that, if the CPU model is one supported by the mboard's bios version, I suspect the CPU is damaged.
You can't tell whether it is damaged by looking at it, unless it's been physically damaged from overheating.
Pictures of blown capacitors, other components, power supplies, Athlon cpu's, etc.:
"Sourced a new Mainboard (I sourced the exact model of the "faulty" mainboard). Installed new Mainboard with just one RAM Module (NEW RAM), ASUS Graphic Card (not the original one that was installed on the old board), left all SATA (DATA) cables disconnected and then powered the computer.
This time there was no BIOS beeping sound. However, no POST on the screen. Checked to see if the LCD monitor is working by connecting it to another computer; LCD is in a working condition.
Removed all RAM modules and Video Card (only left the CPU with HSF and PSU Power Connections connected).
Powered the computer; no BIOS beeping sound. This is the strange part. "
Your A6000 series computer, if it still has it's original PS, probably has a 300 watt capacity PS.
Which Asus PCI-E X16 card did you install ?
If the video chipset on that video card requires a recommended minimum PS capacity of a lot more than 300 watts (e.g. more than 350 watts) , or if the particular PS model can't supply enough current (A; Amps) at +12v that the video chipset requires, then either
- the computer will not boot at all, the PS MAY have been damaged
- or - it does boot but the PS is being constantly overloaded and it WILL be damaged, sooner or later .
Some PCI-E X16 cards have one or two 6 or 8 "pin" power sockets that each must have a single connector, or a matched pair of connectors in the same wiring bundle, from the power supply plugged into
Does it have one or two of those; if so, did you plug in connectors from the power supply into it/them ?
- that if it has that, you must fill the socket(s).
- if the card has two power sockets, if the PS does not have enough suitable connectors, using a Y cable from one connector on the PS wiring to two of the same will NOT provide enough current to the card. A Y wiring adapter that is two female molex power connectors to a 6 pin connector WILL provide enough current, if the PS has enough capacity. .
Apparently at least some of the mboards for the A6000 series have onboard video.
If the mboard has onboard video....
Remove the AC power to the case, remove the PCI-E X16 card, connect the monitor to the onboard video port, install at least one of the original ram modules, restore AC power, try booting the computer.
If you haven't fried the PS by installing the PCI-E X16 card, you will probably have the same situation regarding a beep or beeps that you had previously.
