Blank screen for few seconds then back for a few seconds (loopping)

I just restarted from a situation where my screen went blank, after few seconds came back, but I cant do anything, then blank again (looping continuously) how can I know whats wrong? This is the 1st time it happens but I am quite worried of hardware failures by now. Its a self built PC.

- Intel Core i5 (3570 I think)
- 2x4GB DDR3 1333 Kingston
- ATI HD5670 (not sure abt last 3 numbers)
- Crucial M4 128GB
- Hitachi 1TB

Is there any logs to help identify a probable cause? Or any ideas, maybe its a common minor problem that random pops up in any PC?

It sounds like a graphics driver reset or something?

If you using the proprietary ATI drivers can you make sure you've got KMS off (nomodeset on your kernel line) conversely if you're on the open drivers make sure this _isn't_ on there.

Since that incident, I didnt have a recurrence. I guess its just a normal hang triggered by some rouge application. I used to be using Open Source drivers and have installed proprietry ATI drivers to try out Steam on Linux. The `nomodeset` option was set correctly as u mentioned
