Windows 7 Picture disappears

[bboshot]

I was doing regularly what i do on my computer, and suddendly when i was writing on skype, picture disappeared,black screen, monitor still blue (power button, not orange, didnt turn power saving mode), and i heard 2 strange sounds, btw i was listening music on yt, and after that 2 sounds, music also stopped.
What could be the problem?

Interesting problem.

How is your PC now? Could you reboot and restart? If not what did you see?
There are too much possibilities now:
- overheating, dust in yor PC or a fan has stopped
- outside power problem
- defective part in yopur PC; powersupply, main board ,...
- malware
-......

And please tell us which PC you are using.

By pc im using, do you mean configuration or?

Tell as much as possible, every thing helps.

There is a change that there is a dump. That will be of great help.

Is it possible that you follow the steps in the "Blue screen" section of this forum and post here what comes out?
