So I think there is some glitch that occurs preventing anything from happening.

I did have Raxco Perfect Disk setup to defrag the drives so I disabled that. If the problem persists I am going to put my Windows 7 "C" drive on its own physical diskdrive (with just one partition) and see if that fixes the problem.

As for the memory, I will try and run a lengthy test using memtestx86. However, I really don't think it is causing my current problem. I have been running the PC for several hours now with some memory intensive applications and I never get a BSOD.

We actually need the DMP files created in the crash. use these to find and upload to us. https://www.sevenforums.com/crash-loc...d-problem.html

Update on testing the memory

The only location on my PC where I have found the DMP crash files is at:
C:\Windows\Minidump

The only DMP files there are from my two BSOD incidents that happened after I logged in to Windows 7. Those dates were 4/2/2010 and 4/16/2010. The latter DMP file is the one I uploaded on this thread.

Since that time I have not had any BSOD incidents after logging on to Windows 7. I have had three or four BSOD incidents during the Windows 7 startup (prior to the login screen). There are no DMP files on my machine for those BSOD events. I don't know why but there aren't but there aren't any.

Meanwhile, I have continued on with my system memory testing as suggested by an earlier posting in this thread.

I found something interesting in my memory testing (morning of 4/19/2010). After letting the computer sit powered off over night, I started it up and immediately started with the memtest86(+) instead of trying Windows 7.

On test 5 my memory block from 4000 to 6000 (rounded) failed. So I immediately thought this was it. To further test it I pulled out the memory stick (I have four two GB RAM sticks) in the third slot. I ran the test again - up through test 6. There were no errors. To double check I put the RAM stick I took out back in to slot 3 and removed the slot 4 RAM stick. I re-ran the memory test but nothing failed up through test 6. I tried a few more tests, trading out the RAM sticks from slot 3 and slot 4. I could not get any failure again.

I decided to see what would happen if I took out the memtest86(+) disk and let the machine start up Windows 7. It started fine and I am still running the PC twelve hours later.

Now my questions to resolve are these -
1. Was the RAM test error due to a bad test run?
2. Is the RAM bad? (and is it causing the BSOD on start up?)
3. Is the problem temperature related since I haven't seen the error after the machine gets into Windows 7 (or after the memory test has run a while)?
4. Could the problem be with the motherboard (like maybe a bad memory slot)?

When I power down my PC tonight I will leave the slot 3 empty and put the suspect RAM stick in slot 4. When I start the PC up cold in the morning I will run memtest86(+) again. If the RAM stick is bad I should see a failure in the slot 4 RAM. If I don't get a failure then I will suspect the motherboard slot 3 RAM connector and setup a test for that.

Just a thought, you may try increasing your RAM voltage slightly. Be careful, to much juice will fry your RAM. Increase it one level, the smallest amount possible.

Testing RAM voltage

Thanks for the RAM voltage suggestion. I talked to an Asus technician and he also suggested that. I am trying out a higher voltage now. The real test will be in the morning after the machine has been idle for an extended period of time. I turned it off for about three hours today and ran the memory tests with the higher DRAM voltage and didn't get any errors. However, I don't know if that was a long enough time to say the problem is fixed.

FYI - The Asus technician is also having me check the system voltages using the bios on start up so I can eliminate any power supply problem. As for the DRAM voltage - the voltage was originally set to "Auto". The bios showed that voltage measuring around 1.54v. I check my G.Skill RAM specs and saw that it is supposed to be able to handle 1.6v without any danger. So I am currently running with the DRAM voltage setting at 1.6v.

NOTE:
Since I have been verifying the RAM using memtest86(+) and doing the voltage change I haven't had any Windows BSOD events.

BSOD Resolved - RAM fails even at 1.6v

Well, leaving the machine off overnight then restarting and running memtest86 this morning resulted in the RAM failing at the same place: Test 5 (Block Move, 80 moves). So the DRAM voltage setting at 1.6v didn't help. A support guy from G.Skill told me to send my RAM in to them for replacement so I will do that.

I believe the Windows 7 BSOD in my case can be put down as a PC memory hardware problem.

Note: I am on the PC and in Windows 7 writing this message. After the failed Test 5 memtest86, I rebooted and ran the test a second time. As usual it passed the second time. Once the RAM test passes I can always continue on and login in to Windows 7 without any BSOD.

sonavor, I am also having the same problem as you. My motherboard is also the same as yours (ASUS P7P55D-E).
I have just clean installed windows 7 sp1 and I have had several BSOD incidents during the Windows 7 startup (prior to the login screen). The problem only occurs after the computer turns off for a long period of time (overnight).
sonavor, have you ever found any solutions for the problem?
Thank you.
