Windows 7RC 64-bit keeps crashing and freezing

[Mds]

Hello!
My win7 was working perfectly for about a month.
About 2 days ago i started getting blue screens on my W7RC 64-bit. And that was traced down to one of my DDR3 sticks, which still had warranty and I got a new set yesterday.

Right after the new RAM arrived and i inserted it, I started getting crashes.
Thinking that I might have screwed up the installation I did a fresh install, since I wanted to do that anyway, cause I had W7 on a very small HDD.

But the problem persists, and it's not like when I had the faulty memory stick, this time it simply reboots, or freezes. No blue screen at all(I have turned the auto reboot off). So that makes me think that it's not my new RAM, and I refuse to think that it's faulty AGAIN.
I only got one blue screen right after installing windows and it was about BAD POOL HEADER.

I spent the whole of yesterday trying to figure this out and so far I've managed to find that the system works fine with just one RAM stick.
And I'm starting to suspect ACPI on all of this, cause when I disable ACPI in BIOS i can't even load windows, it reboots at the "Windows Starting" screen.

I brought my RAM sticks to work today and I'll be running some memtests on them to see if its the problem.

My specs:

Motherboard: Asus P5E3 Deluxe DDR3 version
CPU: Intel Core 2 Duo E8500
RAM: 3x2GB Corsair XMS3 DDR 1333MHZ
VGA: Asus 4870 GDDR5 1GB

p.s. no OC has been done, ever.

If you disable ACPI after having already installed windows with it ON, then windows will not boot. If you want to disable ACPI, you will want to reinstall windows.

Is your power supply up to par? If not, that can cause all sorts of problems and glitches.

 

[Mds]

Ok, that is clear on the ACPI.
My Powersupply is a Chieftec, 650W I think, I will recheck it when I get home. And gona bring another one with me, to try and see how it works with a replacement.
What is strange is that it was working just fine till now with the exact same setup(The ram replacement was the exact same set).

I could be wrong (and someone may come by to put in further insight) but a BAD POOL HEADER normally refers to the HD. Check the HD for any integrity error and attempt to fix them

PS If this is incorrect please post here so I will know more now on.

Drivers should allocate I/O buffers as economically as possible, because nonpaged pool memory is a limited system resource. Typically, a driver should avoid calling these support routines repeatedly to request allocations of less than PAGE_SIZE because each allocation that is less than PAGE_SIZE also comes with a pool header that is used to internally manage the allocation.

-Allocating System-Space Memory

hard drive issue sounds about right.

-edit-
i have no idea how to fix that.... sorry

I thought so...good thing because I was wondering if I was just shooting at nothing with that. I had read somewhere before about that issue regarding HDs

 

[Mds]

Thanks for all the replies, I have allot of stuff to check and dig into now
I'm going to try replacing the PSU, cause that can be what is leading to many hardware problems, and gona run Seatools on my HDD

Edit: Memtest 2.01 just ended without any errors on my RAM.

Check Asus Motherboard Forums

Mds,
You didn't mention what version Bios you're using on your board. As a user of many Asus boards, including the one you have, I'd say you have a Bios or Bios configuration problem, assuming the hardware checks out ok. Check ALL your Bios settings carefully.

The Asus Motherboard Forums have lots of threads that may help you. The most frequent reason for a bios change/upgrade by Asus is to deal with memory problems caused by various modules. There is also the well known memory controller problem, common on some of the recent Asus boards. In some cases, boards have been replaced by Asus, because of this. If your hardware memory controller is defective or not playing nice with certain memory chips, often it's a problem difficult to diagnose. Replace board.

It's possible that a Win 7 x64 beta OS could play a role in your problems as described, but highly unlikely.

I wanted to see if there are any updates for the Bios, as I haven't checked in a long while(before I was running XP). But I am terrified to try and update, as it can just crash and then the problem is going to be far greater...

As for the board, I did notice one strange thing - it says I have a single channel memory, when I have a dual chan memory kit.

Do you have any suggestions what I could look for in Bios settings? as it's all on default values?

now this is interesting..

btw do you have a copy of vista 64 or xp 64 to test with? just to rule out if the problem is related to windows 7 x64 or just a hardware problem...

Hmm, no I dont have any copies, I only have an XP x86. Due to the fact that I hate Vista.
The chanel thing might point to the Memory Controller problem that was mentioned above.
