Random black screen (=No Signal) ToMI

posted by Soraky on - last edited - Viewed by 364 users

Hello,
Right now I'm playing ToMI chapter 4 and approximately after 15 minutes of smooth game play, at ANY point of the game, my screen turns black (and reads: "No signal") while I can still hear the sound of the game. But, it is very clear by the sound I hear that the game itself also get stuck. Ctrl + Alt + Del does not work as well Alt + Tab or anything. The computer just dies or something like that. I have to shut it down by pressing the on/off button for a few seconds.
I had no problems with episodes 1 and 2. The problem did appear at episode 3 but I had some hope it won't happen with chapters 4 and 5 (Which sadly it it). I did not change any thing in the computer between the episodes.

My operating system is Vista 32 bit. I have installed the latest drivers - video card is the 'Nvidia GeForce 9600 GT'. Tried running as administrator and compatibility mode of Windows XP. Tried Full screen On/Off and also playing with different resolutions. Nothing helped.
I am sure it is not a problem with any thing else because other games work perfectly (Just played Dragon Age for 3 hours).
Thanks in advance for any help or for even just reading this ^^

  • Here is the GPU-Z log with the actual crash (Got it zipped).

    I made a formatted PDF out of it so you can easily see for yourself what happens.
    When the crash occurs your graphics card is at 135°C, which is 30 K above the specified maximum.

    Something is definitely wrong with your graphics cards cooling. Maybe the heatsink lost contact to the chips?

    Or maybe the fan isn't turning at all? Or maybe it's so clogged in dust that there's simply no airflow going on?

    Come to think of it, the log file mentions the fan speed being at 100% - if that were my Radeon 4850 it'd sound like a hair dryer was inside my PC; but if you're not hearing something similar it has to be the card's fan not turning...

    We checked that already:

    @Leak said: I've checked and the fan on my graphics card is working and clean of dust. Any way I've cleaned my whole computer from dust just 2 weeks ago.

    Wow that is... bad. I'm afraid my PC will go boom soon enough.
    I'll check for ANY thing that is unplugged inside my computer soon. Can you tell me how does the heatsink thing looks like so I can check it out any way?

    Leak, thanks for the help ^^ I do not hear any loud noise, it is like it always was. No dust, and I have cleaned it a few days ago.

    There are many different types. It is the part your fan is blowing onto.
    In this picture you see the transparent fan, and the heatsink is the copper element it sits on.
    Now what is suspect in your case is that the heatsink has no proper contact to the chips below anymore.

    Honestly, I'm pretty sure the fan on the graphics card must not be working (no matter if it was earlier on - or maybe he mistook another fan for the graphics card fan) as there is no way a graphics card could heat up to 135°C (which is probably the tripping point for the card to shut down the PC to prevent itself from melting) without the fan getting set to run at full speed to try and counter that (which it is, going by the log) - and there is no graphics card fan out there that won't make a less than the noise of a jetplane when it's running at full speed.

    So something must be very wrong with the fan, I'm afraid.

    NB: All cards I've bought in the last few years were ATI, so I'm not sure if the same goes for nVidia cards, but all those cards had a cable running from the fan to a 3-pin connector on the card to operate the fan - maybe the equivalent on his card has gotten disconnected?

  • I had a 9600 GT that had the same problem with almost every game I played. I am quite certain it's either a power supply issue or a faulty card.

    Do you happen to know what your power supply is?

  • Leak - I know some thing is wrong but I am positive the fan is working. I opened up my PC and looked at it spinning (And I am sure it is the graphics card fan)
    "maybe the equivalent on his card has gotten disconnected?" Every thing looks connected. Though I can't really tell because I do not understand so much about those kind of things.
    Pale Man- "Do you happen to know what your power supply is?"
    Not really. How can I check it?
    My graphics card did start to make ticking noises after I cleaned the fan yesterday. Like "tick, tickck, tick". But I fixed it (I got the card connected with a slight slope by mistake).

  • I have solved the problem.
    Though I have no idea what have I done. All I did was getting the graphics card out of the PC looking for some thing wrong, found nothing. Than when I got it back inside it was so quite and I played ToMI for 4-6 hours straight (I lost the feeling of time).
    Just finished chapter 5 - Super Epic.
    Thank you ALL for helping me out. With out you guys I would have probably had to buy a new PC.
    Happy new year all ^-^
