Hi folks, hoping ya'll can help. I am just about out of RMA's. here's the build:[COLOR="purple"] Koolance PC4-1025 (basically a custom Lian-Li with built-in exos liquid cooling) OCZ GSX 600w PSU Asus P5N32-SLi Deluxe (came with bios v0210, updated to latest bios v0310) Kingston DDR2 667 (KVR667D2E5/512) X 4 BFG GeFORCE 7800GT OC X 2 Plextor SATA DVD WD Raptor 74GB SATA HD X2 Pentium D 805 [/COLOR] when first assembled it was having some sort of issue with the Nvidia RAID. I updated the bios and it worked flawlessly...for 1 hour, then froze up. I rebooted and it wouldn't POST. I stripped it down to 1 RAM & 1 Video card, I RMA'd the MB and the CPU. still will not POST, it comes on, green light on MB, fans & HD's power on, but KB won't work (saitek KB lights up but no keys work). I then took the P4 3.6 out of my other PC and tried it....WAH-LA! it works perfectly! changed back to the NEWLY RMA'd Pentium D 805 and BAM no POST. I have not RMA'd the PSU. Could it be the 2nd power connector for the 2nd core? wouldn't it still at least POST? any help is greatly appreciated. update note: now the dvd rom tray is opening and closing sporatically....on it's own...like there's a ghost pressing the button. wtf is this? In all my years I've seen nothing like it. Maybe it's a virus or something. Dirk_Daring
