Specs first: motherboard: asus p4p800se cpu: intel 2.8 ghz northwood ram: 2gb geil (512x4) video card: evga geforce 6800gs 256mb (agp) hard drives: 60 gb IBM 7200rpm(ide) 80 gb Maxtor 7200rpm(ide) 300 gb Seagate 7200rpm(ide) power supply: raidmax 470w. I tried turning on my computer the other day, and nothing would show up on the monitor. At first I thought it was the video card, so I swapped it out with an older card I had on hand. Nothing changed, so I disconnected everything except video, ram, and cpu. Still nothing. I thought it might be the motherboard because it wasn't going to bios. So I ordered the exact same model mother board, put it in, and had nothing work. I've taken out the cpu to see if it would at least give me something on the monitor, but nothing has worked. It's not the monitor because i've tested it using my laptop. I know that paste 'paragraph' wasn't very coherent, but if anyone can help at all or has any questions about my system, please post. thank you. 2.8c 800mhz fsb 1 gb 512x2 geil dual channel asus p4p800 se 60 gb ibm 7200 rpm 80 gb maxtor 7200 thermaltake va3000 tsunami sapphire 9800 pro 128mb

Why you would replace the board is beyond me. The primary culprit seems pretty obvious: "power supply: raidmax 470w" = JUNK!

I tried switching that out too. I'll go grab an Antec one later this week and see if that does better than the two I've tried. 2.8c 800mhz fsb 1 gb 512x2 geil dual channel asus p4p800 se 60 gb ibm 7200 rpm 80 gb maxtor 7200 thermaltake va3000 tsunami sapphire 9800 pro 128mb

dude, don't just go out & buy parts...you have to TROUBLESHOOT!

I've just about tried everything short of buying new parts. I've tried swapping parts out with what I have on hand, and I've tried booting with minimal hardware. I don't know what else I can try. 2.8c 800mhz fsb 1 gb 512x2 geil dual channel asus p4p800 se 60 gb ibm 7200 rpm 80 gb maxtor 7200 thermaltake va3000 tsunami sapphire 9800 pro 128mb

Minimal hardware as in no drives, no cards (except video), only one stick of RAM, no external connections other than keyboard & monitor? Do you have a low power video card you can drop in? I keep a 2MB Trident PCI around for troubleshooting. Did you benchtest the new board or throw it right in the case without testing it 1st? Is this your PSU? http://www.newegg.com/Product/Product.asp?Item=N82E16817152014 If it is, I can't believe you would hook up all those drives, 4 sticks of RAM, & a high end AGP card (not to mention the rest of your hardware) to a PSU that only has a single +12v rail rated for 15A! How long have you been running that setup? If the PSU blew, it's hard to say what it may have taken out, but I'm beginning to suspect the CPU. Are you getting any beeps when you try to boot?

No beeps when booting. I've tried minimal hardware exactly as you have listed, and still nothing. The raidmax psu isn't the one i've been using. I had been using the psu that came with my case, and i've been running the setup for over a year. 2.8c 800mhz fsb 1 gb 512x2 geil dual channel asus p4p800 se 60 gb ibm 7200 rpm 80 gb maxtor 7200 thermaltake va3000 tsunami sapphire 9800 pro 128mb
