maybe you feel like your getting close to the problem , thinking it's RAM ?
for what it's worth the relationship between motherboard and ram has always at best been fragile until you find the perfect combination ?
each time you add an extra stick the timings and voltages on many motherboards can change slightly, then to quote since windows 95 Microsoft have stated about memory testing programsnow that you have windows running can you run through the checks I asked for here and especially upload the html output from SIW so we can help identify exactly your RAM make and model and try help match up to your board ?Defective memory chips may not be detected by memory checking tools. Some memory checking programs are not adequate tests because they do not test RAM in the same way that Windows uses RAM. Most memory checkers use read/write cycles when scanning memory. Since Windows is executing code from memory, it uses execute cycles. Execute cycles are different from read/write cycles and are more vulnerable to parity errors. It is possible for memory checking programs to find parity errors if the memory is extremely faulty.
In the interim if you fancy looking for bad RAM slot or sticks I get consistent results by burning to CD (using an ISO burner) & running from boot memtest86+ for at least 5 passes and moving the sticks between slots to verify motherboard ram slots work as well as the ram sticks ?
for 4 gig and over maybe also try version 4.0 ?
ONCE AGAIN - I am back to confusion. I DO think we are getting somewhere with the RAM, but I am wondering what happened with the other reports I sent you? I ran SIW and sent you the HTML printout. Did you not get it?
I will send you another version of it because I have added RAM and rerun SIW, but I have to do it from the other computer. I also ran the Windows 7 compatibility and EVERYTHING passed. I will run it again now.
Now - with various RAM, RAM slot configurations - can I put any single RAM stick in any of the 4 slots and expect it to work? also since I have DDR2 - shouldn't they be installed in pairs?.
FINALLY - the last SIW had a line that read " Accuracy of DMI cannot be verified" What does that mean?
I will send the SIW soon
I assume you have 4 RAM sticks, each 2 gigs, right? Put 1 stick in the first slot... run it like that for a while (or 'till it crashes). If it doesn't crash, put that stick aside and put another stick in the second slot. Again, run it for a while. If you can get all the way through all four sticks, each in a different slot, and it runs OK, then its probably not a bad stick or a bad RAM slot. If everything checks out OK, then try raising the MCH Core voltage by a single step and put all of the RAM back in.

Thanks - Let me give you this info - I ran MEMTEST on all 4 (separate and 2 at a time) and there were no errors on the RAM. I will do what you suggest on testing each one in a slot.
HOWEVER - I have che3cked the BIOS and I have no way of raising the MCH Core. Can you give me a hint on that? I checked the BIOS but there was nothing there about the MCH core.
OK, in your BIOS its called "Northbridge Volt Control". Try changing it from [Normal] to [+0.05]. If it won't accept such a small increase, try [+0.1]. You can raise the voltage up as far as 1.4V which would be [+0.3], just do it in small steps until you reach stability.
PS What type of RAM are you running?
