Random freezes, few but some BSOD, Win 7 X64 new PC

For more background please see thread on asus motherboard forums for more detailed information if I forgot to post something. http://vip.asus.com/forum/view.aspx...d=1&model=P7P55D-E+PRO&page=1&SLanguage=en-us

In short, I was getting random freezes, no restarting and no BSODs. It wasnt until about 3 weeks into the random freezes I started to get BSOD. I only have two so far. This might be good because it actually gives me some tangible evidence now. Generally it would happen from anything as small as only running internet explorer with nothing else open, and freezing while scrolling through or clicking a link. Not always processing intensive tasks. It indeed does seem completely random, so possibly RAM? it is corsair although I guess it could have just as much problem as any other brand. Also I have reinstalled GPU drivers 3 different times, with no change.

Specs:
Intel I5-750
Asus P7P55D-E PRO
Corsair Dominator 4gb (2x2gb, 1333mhz, 1.5V) tw3x4g1333cd9
Corsair 750TX PSU
EVGA GTS 250
WD Caviar Black 1TB WD1002FAEX
Win 7 Ultimate 64bit

from ibuypower, under full warranty, less than 2 months old. I went through the painstaking research of researching every single part I put into the computer and chose them with reliability at the expense of a heftier price. guess that was a waste of time. Temps are stable and dust is minimal as it is brand new.


I also have a file at C:\Windows\MEMORY.DMP it is 384 MB however. not sure if that is of any use. also another note, once the computer restarts from the BSOD, windows gives me the pop up then says click here to investigate (paraphrasing) so I do click, and it just closes and does nothing.
first file 09/04
2nd file 09/09.
the computer is not so unstable that I cannot put up with the problem, as you see there is usually a couple days between freezes. however I want to know why, and it is still warrantied.

EDIT: had to zip files, because of 200kb file limit.

Thank you all in advance.

Memory corruption. Run Memtest on your RAM.

See the link below and follow the instructions. There is a newer version than what is listed; use the newer. If you need to see what the Memtest screen looks like go to reply #21. The third screen is the Memtest screen.

Step1 - Let it run for a LONG time. The rule is a minimum of 7 Passes; the more Passes after 7 so much the better. The only exception is if you start getting errors before 7 Passes then you can skip to Step 2.

There are 8 individual tests per Pass. Many people will start this test before going to bed and check it the next day.

If you have errors you have corrupted memory and it needs to be replaced.

Step 2 – Because of errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test. If you start getting errors before 7 Passes you know that stick is corrupted and you don’t need to run the test any further on that stick.

* Get back to us with the results.


*** If Memtest shows no errors then find the voltage specs of your RAM and compare it to the voltage setting in your BIOS. Do they match?

*** Also, since this is still under warrenty I would contact iPower and have them fix it. Tell them the error code is 0x50 and the minidump file cited memory corruption as the issue.

well heres what happened, the first 12 or so passes showed nothing.. it was about 15 hours in? I walked away and let it continue to run... I came back about 5 hours later and the computer was sitting at the desktop. Does this mean it threw errors and restarted itself? If it did I don't know what they were. How can i check? Also, i changed the auto voltage on the ram (it was about 1.552 and variable), I changed it to a manual 1.500. Not sure if that really made any difference, as the differences were negligible. Again i'm wondering how i can check the memtest log.. hopefully theres a way.
