Hi, I have problem with my system based on Athlon 64 3200 AM2 on ASUS M2NPV-VM board. It was working fine for 6 months then once after reboot it did not boot up, power light is on, fans are spinning, no screen and it beeps: 1 long, 2 short signals which means "video error has occurred and the BIOS cannot initialize the video screen to display any additional information". Now, video adapter is integratred into chipset (nForce 4), so I returned mobo to vendor which took 3 weeks to be replaced (misco uk), I got new board, put everything back on and.. same thing. At this point I realised that althrough video is integrated to chipset, it utilises shared memory, maybe it's trying to initialize screen before checking out memory, so being unable to test my RAM I got brand new stick and, you right, same thing. I'm going to replace mobo once again but now I realised another thing: memory controller on AMD systems is integrated to processor, can it be a issue here if cpu is faulty? In this scenario system cannot find or access memory, video has no memory to run on and points to video failure in first place rather indicate cpu/memory problem? Of course I've tried any possible hardware combinantion to trace the error (including few PSUs, clearing CMOS and so on) and it seems is either mobo (one broken and other, replacement broken on arrival, not very likely but happens) or CPU. Please if you can advise me what to do, I'm really going mad with it. I can't test processor in another pc and don't really want to use PC World service as they're rip off (for their service charge I could just get another CPU). Please, any advice is welcome. Thanks in advance.
