My backup system died today. It was a P4 3.4 in an Intel 915GAV mobo with 2G pc3200 ram.What happened - fired it up to do some updating, all was well for about 10 minutes - then - it shut down. Would not restart. After a bit of checking, I determined that the water Pump on my cooling system had died and the CPU overheated. Cooling block was too hot to touch. After it cooled, took system apart and cleaned and reinstalled the CPU with a large air cooler.Fire up system - mobo led is lit - everything is running BUT no POST. Disconnected all but video card - still no POST.So is the CPU dead or did the mobo get fried.Since this is not a system that I run FSX on - if it is the mobo (my best guess is yes) any suggestions on a new mobo that will accept the P4 and the memory? Rather not have to build a complete new system if I don't have to. Someone suggested an Intel D946GZ - would that work?ThanxVicQ6600 G0 CPU 2.4 o/c 3.65Evga 680i A1 with P31 BIOS 2G XP2-8500 DDR2 1066FSB Mushkin 996535 RAM 5-5-4-12-2T320G 7200 HD partitioned for XP/Vista/Programs 2 - 74G Raptors in RAID0 500G 7200 HD for backup SATA DVD burner Evga 8800GTS 640 PCIx XG 174.74 702/1620/792Kandalf LCS case w/ built in liquid cooling 850W Thermaltake power supplyVisit the Virtual Pilot's Centerwww.flightadventures.comhttp://www.hifisim.com/banners/hifi-supporter-sigbanner.jpg

Well, partial answer and a new question.After thinking a bit, I went back to the system and removed all 4 sticks of RAM. Power up and got a POST beep!Through a process of trial and error I determined that I can have two sticks in Channel A bank0 & 1 but if I put a stick in Channel B 0 OR 1 I get NO POST. Doesn't matter which stick I use, just can not have a stick in Channel B. I can run it just fine with 1G ram in Single channel mode so for a backup system it's not a biggie.Question - how could processor overheat kill a single channel for memory?Thanx,VicQ6600 G0 CPU 2.4 o/c 3.65Evga 680i A1 with P31 BIOS 2G XP2-8500 DDR2 1066FSB Mushkin 996535 RAM 5-5-4-12-2T320G 7200 HD partitioned for XP/Vista/Programs 2 - 74G Raptors in RAID0 500G 7200 HD for backup SATA DVD burner Evga 8800GTS 640 PCIx XG 174.74 702/1620/792Kandalf LCS case w/ built in liquid cooling 850W Thermaltake power supplyVisit the Virtual Pilot's Centerwww.flightadventures.comhttp://www.hifisim.com/banners/hifi-supporter-sigbanner.jpg
