Dual Core CPU won't work anymore in Vista but Single Core will...

This System:

OS: Vista 32
4GB Crucial RAM
ECS GeForce 6100SM-M V:1.0
350 Power Supply (came w/system)
nVidia GeForce 210 Video Card
AMD Semperon 3200+ & Athlon x64 X2 4000+
Some CD Burner/DVD reader

My mother has had this system for several years now. 2-3 years ago I upgraded the CPU to the 4000+ and the RAM to 4GB from 2GB (I think).

Everything worked fine until a couple of weeks ago. Her machine started booting intermittently,and randomly cutting off. I tried the following (condensed list & rebooting after each change):

1) Booted into safe mode - system shut down after loading drivers.
2) Removed the Vid card.& disconnected CD drive. No effect.
3) Booted w/1 stick ram (tried each one separately). No effect.
4) Swapped out PS w/500W Cooler Master Unit. No Effect.
5) Booted into Safe Mode - last driver loaded before system shutoff was AVG driver. Renamed all AVG driver files, rebooted into safe mode. AVG drivers did not load - after last driver loaded, system shut off.
5) Swapped OLD Sempron 3200+ CPU into system - system works perfectly.
6) ran Scandsk /f on HDD - no errors reported.
6) Got a 3800_ Athlon 64 X2 CPU - installed, system will not boot again - exact same problem & symptoms w/this CPU.

It's plausible that the new (used) CPU is bad, but this just seems unlikely that both X2's have the same flaw/symptoms.

I'm thinking that I should replace the motherboard. Any ideas or further suggestions?

Thanks in advance for your ideas and time!

Paul

ECS is one of the worst motherboard manufactures andI've had nothing but hell with ECS. I would advise you replace your motherboard with a ASRock, ASUS, GIGABYTE or MSI.

The motherboard is probably the problem, but to complete your troubleshooting you could rule out the OS by running a linux distro off of CD.

Thanks for the response!

Y, I was not thrilled when I opened it up & saw the ECS logo - my mother saves a lot of stuff but can't find her docs & disk that came with the machine.

Since I had the X2 3800+ which was at this point superfluous I took it back (exchange only) & ended up getting an Asus M3A Green MB (no miniATX this one) for an additional $0.05. Not the ideal choice (ATX, not miniATX - gotta transfer cases...) but all I could find was ECS AM2 boards...

I may see how this works or may swap her over to a box I was given - w/a core 2 Duo 2.0Ghz proc. It'd probably be faster, though I'd kind of like to try overclocking the x2 4000+ if the asus mb works AND can overclock (it's a pretty bare bones model).

Good Idea Rehed! I wish that my Linux skills weren't ~16 years old! It would be easy to try I suppose, though I may also install vista (if I can find her disk) or Win7 to another HDD & test that, though a Linux boot CD/DVD sounds fun!

You don't need to know anything about linux. You just burn a distro, such as Ubuntu, onto a CD/DVD and then run it off the CD/DVD. If the computer will run it it means most of the hardware is OK which means your OS could be the problem.

Many Linux distros have a GUI and are similar to commercial OS's. Ubuntu, Zorin, and others.
