Mobo: ASUS M2N-SLI Deluxe AM2 NVIDIA nForce 570 SLI MCP ATX AMD (Out of the box, arrived yesterday) video card: Nvidia 7900 GS (new 4 months ago) PSU: Apevia 680w Beast Power (new 4 months ago) Ram: 4gigs G.SKILL (4 x 1GB) 240-Pin DDR2 800 (out of the box, arrived yesterday) HDD: WD Raptor (2 years old) CPU: AMD Athlon 64 X2 4600+ Windsor 2.4GHz Socket AM2 89W Dual-Core Processor (Out of the box, arrived yesterday) Bios: Award Bios (Old mobo, and new) Ok so heres the issue. a week ago I had an msi k8n neo4-f mobo in my case, with 1gig of ddr ram and an old socket939 single core processor. It stopped working a while back and would give me either no beep signal or a 1 long 2 short beep signal, so I changed out the video card and it gave me the same signal. I figured it was time for a new mobo and along with it I would need a new cpu and new ram, so above is my current set up. after everything was installed its now giving me a 1 long 3 short bios code, which says that it is either the video card thats bad or the ram. So I switched out my video card again, and no luck (so I suppose I can rule out that.) I then took out the ram and inserted only one, no luck, so I changed that stick to another stick, and still no luck (kinda figured it wouldn't be the ram since its new and all.) this power supply is a great psu and has plenty of power to run whatever I need. At this point I think I have a computer ghost keeping me from running a good machine. =( If anyone has any ideas I would be more than happy to try them.
