BSOD errors, Machine check Exception, Clock interrupt not rec 9C

Hi all im new here,Grab yourself a coffee / tea this is a long one !

For the last 2 weeks my computer which is circa 3 years old is starting to crash quite abit. I am due an upgrade and was going to sell off some bits, but I am having trouble working out which peice of my hardware is causing problems, thus not wanting to buy new kit when the old kit is not faulty.

The i7 920 is overclocked to 3.5ghz alkas nero cooler, v core is 1.26v, cpu temp on idle is 39 - 45 degrees, running Arma 2 it moves up to circa 56 degrees. Motherboard is an Asus P6T6WS revolution with the latest bios. Graphics card is XFX 295 GTX, with latest drivers.

Then :
The problem started when the computer used to randomly freeze (Mainly just as the welcome screen comes up) Then apon reboot id notice my Graphics card drivers disappered and that I had to reisntall them.

I decided to do a format, and after about 3 installation attempts (One attempt ended in my screen going RED tint colour) to get a fresh installation.
I opened up the computer and gave everthing a real clean, this seemed to cure the Red screen issue. As well as a bios reflash

Now :
Most of the time everying runs fine including games, HD video rendering with Sony vegas pro 9 etc.
Then suddenly I get a BSOD crash, normally Machine check exception error, sometomes the clock interrupt not recieved. When I restart the computer and load back into windows I notice the sound is jittery as if there is a loose wire. Loading up a game is also laggy as well as video playing / rendering. I also get this with all overclocking off and everything left stock
Then as the computer is left on for a while on OR restarted the issue is gone. Weird !

I have included (which I hope is correct following the guide) the dmp file of the latest crash as well as a picture , along with my pc probe readings.

Thanks for taking the time to read this, and I hope you can help

Thanks

DB

Hello dirtbag.

upgrade the network driver: Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet NIC. It goes back to Thu Feb 26 14:34:13 2009. And most of the error entries are associated with it.

Download the network card driver from manufactuer's website Realtek
Then reinstall the driver:

1. Click the Start Button, type "devmgmt.msc" (without quotation marks) in the Start Menu Search box and press Enter.
2. Double click to expand "Network adaptors".
3. Right click your network card and click Uninstall.
4. Check "Delete driver software for this device" check box, click OK.
5. Restart the computer
6. If windows does not auto configure the appropriate drivers at startup, install the downloaded one manually.

Anyway, your dump says:

It is a hardware error. You need to test your hardware components.

► Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight, per RAM module per slot.

► Stress test the Graphics Card using Furmark.
Video Card - Stress Test with Furmark

► Stress test the CPU.
Hardware - Stress Test With Prime95

But, as long as the Service Pack 1 and other updates are installed, there is a chance of instability in software's side.

Hi okay so far I have tested my gcard and had furmark running at 1900 x 1200 (my native res) for 10 minutes, max temp 91 and no higher, no artifacts.
Is it safe to say the Gcard is in the clear ?

Ran Prime 95 on the CPU, had probe 2 running at same time. Within 3 minutes the temp raised to 80 and alarm went off so I stopped the test. I have (what I think) a good cooler alkas nero and with my machine oced it keeps it idle under 40 sometimes. Have I found my problem, the cpu ?

I also had a clock interupt crash just now so I've added the file for you to look at

Need to test the ram next and report back
Thanks again

CLOCK_WATCHDOG_TIMEOUT (101)
An expected clock interrupt was not received on a secondary processor in an
MP system within the allocated interval. This indicates that the specified
processor is hung and not processing interrupts.
Arguments:
Arg1: 0000000000000019, Clock interrupt time out interval in nominal clock ticks.
Arg2: 0000000000000000, 0.
Arg3: fffff880030f9180, The PRCB address of the hung processor.
Arg4: 0000000000000006, 0.

Follow it: STOP 0x101: CLOCK_WATCHDOG_TIMEOUT troubleshtg

So you got the result. Now Test the modules individually, to rule out the faulty one.

Most possible. A corrupted RAM can make all the troubles.

Hi, I found the bad stick with first attempt and removed it. Ran memtest over night no errors. Ran Prime95 and worked fine, furmark again fine. So lets see if i get any more errors. Once again thanks very much for your help
