Answer 1

Okay, you've tried reseating the memory and that hasn't worked. Try swapping the location of the memory. If you have only one stick of memory in the computer, try moving it to another memory slot and then boot the computer.



If you have more than one stick of memory, try removing all but one stick of memory and boot the computer. If this does not resolve the issue, remove that stick of memory and try one of the other sticks of memory. Repeat for each stick of memory in the computer, to check if any one of the memory sticks is causing the problem.



If you have access to another computer that uses the same memory, take memory from that computer and install in your computer as a test.



If another computer's memory works, you know that your computer has bad memory. If another computer's memory doesn't work and it is compatible with your computer, the motherboard or its memory slots are defective. You would need to replace the motherboard to fix the problem.

Answer 2

Swap out the ram try a different type of ram a little lower mhz than the one you have and see if that will fix the problem could be a bad gpu try swapping that out with another one

AMI BIOS:

1 beep - System boot successfull

*1beep - Refresh failure - (NO VIDEO) memory refresh failure (bad memory)

2 beeps - Parity error - bad memory

3 beeps - Base 64K memory failure - bad memory

4 beeps - Timer not operational - bad motherboard

5 beeps - Processor error - bad processor

6 beeps - 8042 gate A20 failure - bad cpu or mainboard

7 beeps - Processor exception interput error - bad processor

8 beeps - Display memory read/write failure - bad video card or memory

9 beeps - ROM checksum error - bad BIOS

10 beeps - CMOS shutdown register read/write error - bad motherboard

11 beeps - Cache memory bad - bad CPU or motherboard

12 beeps - BIOS rom file incorrect size - The BIOS ROM file found does not match the size of the flash device

13 beeps - BIOS rom image mismatch - The BIOS ROM file layout configuration does not match image present in the flash device

5 short + 1 long beeps - Memory error - No memory detected in the memory slots.

6 short + 1 long beeps - Memory error - EDO memory detected in system

7 short + 1 long beeps - SMBUS error



Motherboard may possible need to be replaced if you have already replaced the RAM. Try to replace the RAM first.

And what diagnostic info suggested the problem was related to the RAM or the CMOS battery?
