I'm new to your forum and just wanted to start off with a "HELLOW" to everyone.I've been building and repairing PC's, servers, and multi-function printersfor the past 5 years and have run into a problem I can't seem to diagnose. I am hoping you all on this forum can please help me out.
First let me give you my system specs:Foxconn i945G Motherboard, model: 945G7MA-8EKRS2. http://www.foxconnchannel.com/products_motherboard_2.cfm?pName=945G7MA-8EKRS2
Intel Pentium D 820 CPU, 2.8gig dual core.

Two 74gig WD Raptor Hard Drives, running in RAID 0 (stripped) & one 250gig WD drive for storage.
Corsair XMS PC5400 RAM 2x512MB dual channel. http://www.newegg.com/Product/Product.asp?Item=N82E16820145539
Sound Blaster Audiogy gamer, PCI.

Ultra 600 watt SLi power supply. http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=373061
Well these are the important parts anyway. The problem is while the PC is runnning it's fine no problem at all. When the PC is shut down and left off for over an hour the next time the PC is started it will not post. Infact I can't even hold the case power button to turn the fans and power supply off. I have to cut power from the power supply itself. Then when power is flipped back on the system works and goes directly to the bios. I believed the problem was the motherboard as the voltages from with in the bios were off.
The pentium D 775pin cores are supposed to run between 1.25v to 1.42v. This core is running at 1.24v?
The RAM is supposed to be at 1.80 buy default. This ram is running at 1.77v?
I tried to use the overclocking options from the bios to force the CPU Voltage from 1.24v to 1.34v and the the RAM from 1.77v to 1.95v. I set the RAM this high as 1.9v is what is required for this performance RAM. Needless to say the problem happened less often but it would till do it about twice a week. I called Foxconn and they had me RMA the board and they shipped me a brand new one. Still the same setting are showing in the bios.
What is causing my system not to post, this is driving me nuts?
Any help would be greatly appriciated.
