Windows 7 - Random System Crashes (No Blue Screen)

Hey All,

I am experiencing some disturbing shut downs on my new custom pc and would really appreciate some guidance.

Just to be clear, these crashes do not provide a BSOD and therefore no error code for me to research and correct.

In the last two days, this has happened 4-5 times, and most often while watching streaming video online or DVD video (but also while browsing the web). Without warning, everything will lock up (sometimes this is accompanied by a terrible sound emitted from the speakers - presumably looping audio from the video i was watching). I then have no choice but to power down the pc manually and reboot. It strikes me as a hardware issue but I hope this is not the case.

I have attacked SF Diag logs. I will do my best to answer any questions.

Thank you in advance.

System Info:
Windows 7 x64 Full Retail
System/OS approx 6months old

No one has any ideas? It's still happening.

*bump.

Please help me!!

Before anyone asks, my drivers are UP TO DATE, and my BIOS is up to date as well.
So far, I have asked around and most people point to my graphics card overheating, or a very dirty (dusty) pc as a likely cause. Firstly, my computer is generally kept very clean, and I am monitoring my GPU temps and they are usually WELL within normal ranges (frankly it runs very cool). I have called EVGA for support, and they told me they had not heard of this problem before. They had me run a bunch of gpu stress tests, all of which provided no clue (they were clean) as to what could be wrong. Someone else told me to make sure my RAM was properly seated. I did check that and I can't see any seating issues.

<solved>

only just spotted this thread sorry :/

was it power supply ?

Would be useful to know what it was and how you solved it ?

Hey ickymay

Problem turned out to be a bad stick of RAM, so I pulled out the offending stick and problem disappeared.

thnx for posting back and glad you solved it
