Hey all,


I have a stationary.

It recently began to randomly go to black screen. First i thought the monitor just lost signal and i tried to remove the cables, that dident help. I then noticed that my keyboard also was frozen. Apart from that everything sounded normal, the fans was spinning, all lights was showing and so on. I could see or hear a thing that would indicate something was wrong.

One thing that i did notice was that, sometimes one fan speeds up very fast for 2 seconds tops, and then speeds down, and then the screen goes to black. I really havent found out what fan it is, since i only have 2 seconds to look, and the capinet is kinda big.

I felt the different hardware and none of it feels hot.

I can run for 1 day without problems, restart 3 times in a row with the same issue, or i can turn it on, wait 5 minutes and then it happens again.

Its randomly, and i cant really isolate a issue.


I did try to update my grafficdrivers, because i thought that might was the issue.


So the short version is, everything sounds fine, screen looses image and goes to black screen, blinking as if nothing was connected, and keybaord is frozen, computer dosent interact with the keyboard. I have to force reboot it.


I really need some advice/help.

In regard thanks and i hope someone have a solution or an answer :)
