Conclusion: Bad memory stick

Ok. I emailed Corsair Last night. Ok, here is the background. I built this computer last December. Since, I have had the same consistent so to speak problems. I have RMA'ed the motherboard twice, second time it was replaced with a new one. You can safely remove that from possible problems. The video card was RMA'ed once due to being defective on arrival. The processor has been switched out with a 3800+ dual core to have the same results. The hard drive has been formatted and changed 3 times with known working hard drives, brand new. I have checked the voltages on the power supply with a DMM and found that the voltages stay fairly constant and at good working values. I have tried all drivers for the motherboard, including new and old to see if problems would be fixed. Several months later, problems still persist. Also, memory settings are set in bios as 2.5-3-3-6 at 2.75 volts. No overclocking has been done, all stock speeds.

 

Here are the symptoms. The most common problem was the computer would freeze if I left alone for a given amount of time, most commonly overnight. Hibernation and standby is turned off as is screen saver. Sometimes the clock would freeze, other times it would not. When the clock didnt freeze, I was still unable to move the mouse or use the keyboard as if usb devices were disabled or lost connection. Hitting the power button would send the OS (Windows XP Pro SP2) into shutdown but would freeze at windows is shutting down. Second common problem is the sound would turn into beeps. Any sound that came out of the speakers would be a beep or heep or whatever you would like to call it. Another problem is the computer would just plain restart it self for no reason. All temperatures are within operating numbers 34C for cpu and 23C for motherboard. The problems were consistent with changing out processor, hard drive, vid card, etc.

 

Now, I ran memtest86+, superpi, and prime95. I only let memtest86+ run for a couple hours before I stopped it, which came up with no errors as of that time. So I ran prime95. This would end with the message of hardware defect detected after about 6 1/2's everytime, consistently 10 times. Ran superpi. This would randomly end saying in rounding error, more commonly on the 2M value. So tried each stick by itself. One stick has the errors consistently and mroe commonly, prime95 ending in error after about 1 hour, and superpi random errors, but more often. The other stick has not given one error as of yet and I have let the computer sit overnight as of Sunday and has not frozen or restart or distorted sound yet. This leads me to the conclusion that one of the sticks is bad. I am still waiting contact with Corsair to I can get an RMA number. Any info as to speed this process up, help, or further suggestions that I could try would be most appreciated. I have waited quite sometime to have a running, stable computer. I hope I can resolve this speedily. Thanks.

First, I so far have reinstalled windows with the one stick of memory that I didn't get errors with. I think the other stick corrupted part of windows because I couldn't format a floppy disk. Kept saying windows is unable to format this disk or similiar to that. So far with a fresh install of windows with the one stick is going good. Hopefully it can pass the test of leaving overnight for several nights without freezing or restarting. Thanks for the help!

This is just absolutely frustrating. With the one stick in, the one that doesnt come up with errors in testing, the computer still exhibits some of the problems I was having. The problem that I still get is that when the computer is left alone for a while, the usb devices will lose connection and if you try to reconnect them, the computer doesn't recognize them, except for flash drives it recognizes fine. And after plugging my mouse into a different port for the second time, the computer froze and I had to hard reset. This just doesn't make sense. Thats what makes me think its a motherboard issue, but I have rmaed the stupid motherboard twice, once it was "fixed", still had the issues, second time they gave me a completely new/different one and I am still having the same problems. I am going to stick a stick of ddr2100 just to see how it reacts to that, again. Hopefully I can get some clear cut answers. Thanks again.
