Memory Issues... Please help!

Please help! I have a computer that I built a few years ago, and I have had no issues with it until after installing some new ram i saw a "memory management" BSoD. After that I double checked and realized I accidentally mixed two 1.5V modules with a 1.65v module. I removed all of the modules and tested each one individually with memtest and only one of them reported errors. I then reinstalled each of the good modules one at a time and ran a final test, which reported no errors. After that I was able to successfully load my OS (Windows 7) and run it overnight without issue. But just a moment ago it suddenly crashed, with no blue screen or error message, and wouldn't even POST. The motherboard sounded the 3 beeps that signal a memory issue. I was, however, able to remove the modules and reintsall them one at a time to get it to POST successfully, and I am running memtest again, but so far it has reported no errors-- just like the first time. I'm not sure where to go from here. Do you think this could be a software issue? or which hardware component, if not the memory, could be faulty? Does anybody have any suggestions?
 
Lets hear about your computer .... What are the specks ? Tell us about the ram sticks you are using .. What Kind of ram are you using ?
Tell us the Make size and model number....
 
Motherboard: Intel Dp55wb
Graphics Card: nvidia Geforce 8400GS
Processor: Intel i7-870, 2.93ghz

and I am currently using 3 corsair DDR3, 2GB, 1333Mhz, 1.65V, ram sticks. I'm sort of new at this (this was my first build) and it has been working fine for 2 years. Last night I ran memtest86 overnight with all 3 sticks in and no errors were reported. I reinstalled my OS, and It's running now, (I'm posting from it) but I'm not sure if the problem has been solved or not. Do you know what else the problem could be, if it's not the ram? could it be the motherboard? I'm not sure how to test that, and I don't want to buy new ram if it's not a ram issue.

thanks for your reply by the way. I really appreciate your willingness to help
 
Your Motherboard say it supports 240 pin DDR3 1333mhz/DDR3 1066mhz (1.35volt) You have 1.65v... this might be a problem..
Try running 1 ram stick for awhile to see how it runs, then try the other one..your Ram voltage might be to high for the motherboard..
Most freezing up comes from Ram or heat... Check all fans in the case...check your heat temps..
 
Where did you see that? on the website it says "Unbuffered, non-registered single or double-sided DIMMs with a voltage rating of 1.65V or less." and is it possible that that is the problem even though it just started having issues recently? it worked fine for two years... I'll buy some new sticks though, because that obviously seems like an issue, but i'm confused as to why it was working for so long, and then all of a sudden these problems pop up now. The ram i'm currently using is the original ram that i had installed.

here is the website i'm using
http://www.intel.com/support/motherboards/desktop/DP55WB/sb/CS-030682.htm

all the fans are running properly... as for the heat temp... this may be a dumb question but how do i test that?

thanks for your help. I really appreciate it. :)
 
I've had this problem recently. Although I have different specs, I also used 2 RAMS with different voltage. Actually, the problem is not with the MoBo. It is with the RAMS you are using. Using 2 RAMS with different voltage will result to damage on the RAM with a lower voltage. Your computer maybe running with 3 RAMS right now but eventually 1 or 2 RAMS with the lower voltage will be damaged permanently in time. Best fix will be to use RAMs with the same voltage.
