Hi all, Here's my little story. I bought my computer in last October with the following configuration: CPU: Intel Core 2 Duo E6750 MB: Asus P5N32-E SLI Mem: 2GB kit (1GBx2) Ballistix Tracer Gfx: Gigabyte GeForce 8800GTX HD: 3x Samsung HD501LJ 500GB (in RAID 5) PSU: CM Real Power Pro 850W RS-850-EMBA (80 plus) Case: CM690 Monitor: Dell 3007WFP After I put together the pieces and installed everything it went well for a few weeks before the Asus board failed and I had to RMA it. Since I couldn't go without my computer for the 2 months it would take to get a replacement, I bought an Abit IN9-32X-MAX Wi-Fi (pricey but I had read good reviews of it). I plugged everything back on the new board and it worked like a charm, even recognized the RAID array I feared I had lost. I noticed the cold boot issue but I didn't pay too much attention to it at first cause I was just happy to have my computer working again. Two months after that, on the same day the store called me to tell me the new Asus board was arrived, I got a BSOD and couldn't boot the computer anymore. I went to get the new Asus board and switched it back in the system but the computer wouldn't boot. I went back to the store to find out that both motherboards where working fine but it was the memory this time that wasn't working. As a replacement, while waiting for the memory RMA, I bought a kit of 2GB G.Skill (F2-6400CL4D-2GBPK). Now my sytsem specs are like this: CPU: Intel Core 2 Duo E6750 MB: Abit IN9 32-MAX Wi-Fi Mem: 2GB kit (1GBx2) G.Skill (F2-6400CL4D-2GBPK) Gfx: Gigabyte GeForce 8800GTX HD: 3x Samsung HD501LJ 500GB (in RAID 5) PSU: CM Real Power Pro 850W RS-850-EMBA (80 plus) Case: CM690 Monitor: Dell 3007WFP The system is running now but I'm having what appears to but the cold boot issue. I can only boot after unplugging/plugging the power cord from the psu. I checked and I have the 80+ version of the RS=850-EMBA (stickers both on the box and psu). Interestingly, the problem seems to appear only when setting the delay for the power switch in the BIOS to on. When in instant-off mode the problem is gone. Also, I noticed there's a lot of "electrical" noise (lack for a better word) since I installed the Abit board. So, do you think the problem is with the psu or the Abit board or the combination of both ? Thanks in advance for your help.
