Can't install operating system. HELP!!!

[drkmarine]

Hi guys, I just built brand new computer. For some reason, I am having problems installing ANY type of operating system onto this computer. These are the specs of the computer:
-----------------------------------
*GeForce FX 5700LE 128Mb DDR w/TV-Out & DVI 8xAGP
*ECS NFORCE3-A (1.0A) Socket754/nForce3 250/FSB1600/A&L/ATX Motherboard
*AMD Socket 754 Athlon 64 3400+ CPU, 512K
*512MB KINGSTON D400
*250GB SATA Western Digital,7200 RPM, 8MB Cache
*computer case w/ 450W PW Supply
-------------------------------------
Okay, I tried installing windows 95, 98, 2000 pro, xp pro(sp1), xp pro(xp2 integrated), and even Linux. But for some reason the installation keeps getting errors. For windows, I keep getting the blue screen of death, randomly, never at the same spot. The blue screen gives error codes, all of them are ram related codes. The installation stops at 6% some times at 99%. And a few times, it goes pass the copying stage and gets to where you can see a "estimated" timer, then it gives the same error codes again. I know it can't be the cd, because the cd is clean, and i tried multiple windows versions, all same results. And for linux, it just installs for some time (fairly short), then it freezes. Can anybody help me out here? What could be the reason for this to happen? Is there anyway or anything wrong with my setup? Anything will help.

I've tried 5 different ram sticks. 4 Kingstons and 1 Ultra. All the ram sticks are 512mb. I tried both ram slots. I tried different video cards, the regular nvidia 5700LE and the 5200. Still same results. I'm guessing it maybe faulty motherboard. Could that be the cause?

I even went as far as changing hard drives. I tried installing on a EIDE 40GB Seagate. Still same results. The motherboard recognized the ram, video card, and cpu fine.

Any suggestions?

Have you checked in the BIOS to make sure everything is okay in there? For instance, to make sure the cpu and memory are not overclocked. If you haven't, you might go into the BIOS and there should be an option on the main page for setting everything to default values. Select that, save, and reboot. If that doesn't help, go into the bios section that deals with the ram memory, and if it gives you the option for changing the timings, make sure none of the timings are set too aggressive. Might also try turning off ram functions such as shadowing and caching.

What name brand is your power supply?

I would not be surprised if the ECS board is defective. Those are budget boards with inadequate quality control.
