I got a new computer a couple of months ago, and since the very beginning I've been having some problems with the memory. At the beginning the problems seemed more random, but after updating to a newer BIOS the problem has been this:
When I boot up my computer for the first time after it has been shut down for some time, it always crashes when loading Windows, or if it manages to get to Windows I get applications crashing followed by BSOD. Running Memtest during start up shows up a huge number of errors.
However, when I shut down the computer (not just restart, but really shut it down), and then start it again, everything works fine. Memtest shows no errors, and I can keep the computer up for days and run any stress test and there's nothing wrong.
Then the next morning the same thing always repeats. First boot-up -> mem errors, bsod, crashes -> Second boot-up -> everything works fine.
I'm pretty much at loss here, since I've never really seen anything like this before. Here's what I've tried so far:
- Loads of different BIOS settings, also with the help of support person from the memory manufacturer Mushkin. Different settings don't seem to make much difference, with the second boot pretty much every reasonable setting seems to work, and with the first boot nothing does.
- Run two passes of Memtest on a different computer for both memory sticks, both came up with no errors.
- Booting up with just a single stick of RAM. This usually works better, the first boot shows less errors and comp is usually stable. Nevertheless, there still are memory errors.
- Reassembling the whole computer (CPU, memories, display adapter etc.)
- Updating BIOS, currently running the newest version (1101)
I haven't been able to try memory from other manufacturers since none of my friends have DDR3.
Here's the specs of the computer in question:
Intel Core i5 750 2.66 Ghz
2x2048MB Mushkin Blackline DDR3-1600 CL7 Kit "Stiletto" (7-10-10-24)
1024MB Asus Radeon EAH5850 DirectCu
80GB Intel X25-M
Enermax 525W Modu 82+ II
Windows 7 64-bit
My friend ordered a completely similar configuration at the same time and he's having same kind of problems, so I find it hard to believe there's problems with the hardware (unless there's been a whole box of faulty memories of course).
So is there any ideas of what could I still try, or what is the most likely reason for this problem?
Thanks in advance!
