Computer would not boot up after adding RAM
Motherboard ABIT KN8 SLI NF4 SLI RT
Video Card ASUS N 73000S EN7300GS/HTD/256
CPU AMDIA64 3000+ 1.8G 939pin 512K R
Memory 512Mx2 Kingston KVR400X64C3AK2/1g
Hard Disk 250G Western Digital 7K 16M SATA WD2500YD
DVD Burner Pioneer DVR-111 D Black
BIOS set to Optimized Defaults.
As stated above, the computer was initially configured with 1 gb of matched pair of Kingston 512 mb memory sticks. After adding a second set of Kingston matched pair 512 mb RAM memory sticks, the computer would not boot up.
It had the following symptoms:
Symptom set #1 – No indication of POST, Motherboard LED lights lit-up, Fans for CPU, power supply and tower started normally, green LED power light lit-up, orange HD LED lit-up for about a second and went out, no POST beep, however after about 2 second the tower starts continuously beeping in about 2 second intervals. No start up indications from monitor, keyboard or mouse. No discernable sound or LED indication that HD was running.
I removed the second set of memory sticks, but again got Symptom set #1. I have tried resetting the BIOS, but again got Symptom set #1. I then tried several variations of memory installation that always result Symptom set #1.
Finally, I tried installing the second set of memory sticks in bank 2, leaving bank 1 empty. Now I get the following symptoms:
Symptom set #2 – Computer starts to boot up normally but regularly crashes. Have performed memory diagnostics – STRIDE -6 failures. Note: Prior to adding the second set of memory sticks, memory diagnostics tests did not identify any problems.
Is this a hardware problem, or could it be a faulty BIOS? I’m hesitant about updating the BIOS – I don’t want to make things worse.
