I am getting this error more and more often,usually when I plug in anything into usb ports,the screen goes black and NO SIGNAL DETECTED is shown on screen.
Sometimes when I just start the pc this happens after windows loading screen,and by hearing the sound of windows loading I can say that the windows loaded fine only display is not shown.
Also happens when
-switching tabs while playing a game
-when plugging in speakers
-when I disable my network adapter

This error is really annoying and bugging me,I have to restart my pc directly whenever this shows up,and I often lose my work because of that.

Please help,my pc specs:
Dual Core E5200 @ 2.50 Ghz
160gb IDE hdd
Nvidia 8600 GTS
2 GB CORSAIR DHX DDR2
Windows 7 Ultimate Edition (32 Bit)

If the screen goes black immediately when you plug in a USB device or speakers, do you notice a static shock or spark?

Never saw a spark,but sometimes I hear sounds of Plugging and unplugging,like something is getting plugged and unplugged,hear those sounds for first few seconds and then its just black screen...

I checked the cord,its fine,and lcd looks fine too..

I removed my video card then started computer and tried to do every possible thing that gives me No Signal Detected,and I didn't get the error :| So I am thinking that it could be my video card that got faulty?

I doubt it is the card. No signal detect would point to a monitor, or monitor connection problem. As it worked without the card in??, I would have a look around where the monitor cable is plugged in to the card. Do you have a spare monitor cable you could try?

Yeah I don't think its the card because as I continued using my computer without video card,I could hear the same unplugging/plugging sound at some times,and see the screen flashing(like it does before no signal detected),although I didn't get no signal detected but there were signs that could tell me that its not the video card... I am totally confused now....
I do have a spare cable,I will try using that and see if it works

EDIT: Its confirmed,its not video card,I got the no signal detected even without the video card
