Mesh system built Oct 2006.
AMD 64 AM2 cpu, Asus M2n32-sli deluxe motherboard, 2 x 1gb kit PC2 7200 OCZ2N9002GK Dual CH EPP 220.127.116.11 DDR2 memory, NVidia Geforce 7950 GX2 graphic card, PSU HEC 550w.
My Son dragged this wreck - sorry rig - home this Christmas when he said the hard drive caught a virus.
When I turned it on, all fans and panel lights started, and speaker emitted 1 long beep followed by 2 fast beeps. No post. Nothing on the screen.
I stripped all the plugs out and restored just the memory, graphics card, fans, front panel connectors, CPU, monitor, and of course the PSU.
On power up, it still emitted the same beep codes.
Powered down, removed both memory sticks.
Replaced one stick at a time in both A1 and B1 yellow slots. Each time trying to startup the system. Only with one stick in B1 slot did the single beep sound and the screen lightup with the Asus Lifestyle splash screen. "Press del or tab to continue....." but of course there was no keyboard attached. So I assume the GC and Mobo is OK.
Powered down, attached keyboard, powered up. No beep. No post.
Powered down, removed keyboard, powered up. No beep. No post.
Powered down, removed memory, powered up, got 1 long, 2 short beeps. No post.
Powered down, replaced this same stick in the same B1 slot, powered up, got 1 beep and the Asus splash screen.
I RTM for the mobo and tried clearing the rtc cmos ram. no change.
Obviously faulty memory in part, but what else - PSU?
