  1. All,

    I have just built my new PC a week ago and it has been generally very stable apart from 2 random restarts which happened whilst I was installing various software from CD's after setting up windows (which did not show a BSOD but wrote a error stop 102 in the event log), however I did not see any repeat of these, and have been using te PC intensively for office apps and extracting AVI files onto DVD's for watching on my home cinema system.

    However until I started playing World of warcraft at the weekend while installing another game in the background from a CD. The machine restarted- no BSOD, no error in the event logs, just the power going off and the machine restarting. I have 'restart on error' disabled, but still no BSOD.

    It *seems* that as soon as the DVD drive & hard disk is working while I am doing something graphically intensive, the machine restarts - the only way I could reproduce the restart was to load up WOW and have a cd/dvd related activity going on at the same time. Any time I do this, at some point within a minute of setting it all off, the machine restarts.

    I had another random crash today (after 24 hours stable running), this time just doing web surfing and not installing anything but had just lost my internet connection and was reconnecting. When I looked in the error log there was again no error, but a system event notification:

    Error 1001
    The computer has rebooted from a bugcheck. The bugcheck was: 0x1000007f (0x00000008, 0x80042000, 0x00000000, 0x00000000). A dump was saved in: C:\WINDOWS\Minidump\Mini100306-01.dmp.

    I looked further and these were generated also when I had the previous crashes. Anyone know how to interpret these files? I have attached them to this post.

    Here is what I have checked:-

    - Temps - According to PC Probe the CPU runs 45 idle, 55 maxed out and when these restarts happen it has not been higher than 50. I have had it running stable with higher temps encoding DVD's without problems
    - IRQ - graphics card is on it's own IRQ, DVD drive is not sharing an IRQ.

    Any ideas what could be causing this? Could it be either memory of the PSU? I have a 620W PSU, so I cannot believe that I am overloading it!

    I am going to run a mem test tonight, but also wonder if it could be a PSU issue since the restart seems to happen when I have the graphics card working away as well as the DVD drive and the Raptor? Or could the DVD drive be faulty?

    I have the SATA devices working off the Intel ICHR7 controller, the DVD burner working off the secondary IDE channle and the JMicron controller is switched off in the BIOS. CPU & memory are working at default speeds. My case has 4 fans (1 intake, 3 exhaust) and a lot of space for airflow.

    Anyone seen anything like this? Help appreciated!

    Hello and welcome to Techspot.

    2 minidumps are corrupt and unreadable.

    3 miniumps crash at RtkHDAud.sys. This is part of your Realtek audio drivers.

    Try updating your Realtek audio drivers and see if that helps.

    I think it`s probably a good idea to test your ram as well, as a bugcheck of 7F is often caused by faulty or mismatched ram.

    0x0000007F: UNEXPECTED_KERNEL_MODE_TRAP

    One of three types of problems occurred in kernel-mode: (1) Hardware failures. (2) Software problems. (3) A bound trap (i.e., a condition that the kernel is not allowed to have or intercept). Hardware failures are the most common cause (many dozen KB articles exist for this error referencing specific hardware failures) and, of these, memory hardware failures are the most common.
