My PC still shows up blank and I have tried everything!

[zmatrix]

I had a CUSL-2 running a P3 700 at 959Mhz before this in an Antec SX830 running 6 HDs, one CDRW, one scsi cdrom, a zip drive and all PCI slots filled, 5 80mm fans, and a Global Win CPU cooler.

One day, I came home to find my monitor blank and realized after booting, my pc did not post. No Bios info, no memory count. Nothing. Even after I shut off the power, it didn't do anything. After some members suggested that I could of overloaded my PS or that my mobo had fried. So fine, I decided that it was time for an upgrade.

I picked up an Antec TruePower 420, a ECS K7S5A with the tbred 2100+, and a thermalright SK7 to boot. I put my old ram onto the new mobo. I have two sticks of Crucial SDRAM. Ok so I go to power it up and same crap happens! The screen comes up blank. No bios, no info nothhing.

I thought maybe it was my monitor. I plugged my lappie into it and it worked fine. Next I subbed out my Geforce Ti500 with my old Gladiac GTS and still the same thing happened. I pulled out everything out of the slots and left only one HD and the Ti500 and booted it. Same thing again. I then yanked out my ram and switched them. No help. Then I used one stick by itself, changed slots, then tried the other stick by itself, and then switched its slot - still nothing.

I am at my wits end. Can someone out there help me? I can't think of what else may be the issue. Thanks for any help!!!

Reset the breaker and plug it in.

Make sure to reset the CMOS after each time you change things too. Maybe even take out the battery and unplug it for an hour or so. Do the fans and PSU spin up?

An hour is overkill. 30 secs should do it. Do you have any kind of response from turning the psu on eg. HD light turns on, fans spin etc? In fact, do you get any HD activity at all? Are all the cables plugged in correctly. Are all PCI cards seated correctly? Have you considered both sticks of RAM could be burned out?

All the fans come on, including the CPU one, my hard drives do spin up but doesn't sound normal. I tried two different bootable HDs and same issue. I reset the CMOS once, and my IDE cdrom lights up. HD activity lights show.

Right now, the only issue maybe my two sticks of RAM. But for both sticks to burn out at the same time is so unsual. Any way I can test RAM?

Try each sick individually.

Can you try setting up either motherboard outside of the case on a board or newspaper? This would eliminate a case issue. We had a computer at work that would not fire up with the system board in the case. Removed the board, fired it up out of the case, and it worked fine. We searched that case and never found what the deal was. We ended up ordering a new case and it worked fine.

Get things plugged in like you would if it was in the case, minus the LED connections and that stuff, and then find the power switch connector on the motherboard, and touch those two pins with something small and metallic. I use a tiny screw driver or pen that has a metal tip. The motherboard needs to be elevated or have one side off the edge of the board or table you have it on, so you can put the video card in and not have it pop back out, because the back plate sticks out beyond the bottom of the motherboard.

Wow this is perplexing. I tried the whole mobo outta the case deal with my old setup and new setup like redbeard suggested and it didn't fly. Right now, the only thing left I could figure is that the ECS mobo I got is also defective. I would imagine that at least if the motherboard was good, at least the bios will show up regardless if there were missing elements or if there was bad ram. I mean it powers up, just doesn't show the regular bios info and the memory count. My monitor even says outta range when I hit the OSD menu which I find odd for both my Geforce cards.
