Video signal lost and pc shuts down on Win 7 64 bit with NVIDIA GT 320

simorame · 02 Jun 2011

In the last few days I have experienced a serious problem that is preventing me to use my desktop pc. The computer is an Acer Aspire AX3900 running Windows 7 64 bit with Intel i5 processor, 6 Gb RAM and NVIDIA GT 320 graphic card.

This is what has been happening: when I boot the pc, both in normal and safe mode, everything works fine for a few minutes, then the monitor suddenly loses the video signal and there is no way to get it back without rebooting. Sometimes the pc shuts down too after the video signal loss, sometimes not. I have Teamviewer installed on my desktop pc and connecting with a notebook I have realized that the pc is still working fine when it did not shut down after the video signal loss. The longer I leave the pc switched off, the longer the video signal stays on, but never more than 5-6 minutes.

I have googled a lot to try to figure out what the problem may be and find a solution, but with no luck so far. However, I reckon the problem could have something to do with a recent driver update of my GT 320 card. Indeed, last Sunday I installed the trial version of Adobe CS 5.5 Master Collection and when running Premiere Pro for the first time it asked me to update the graphic card driver in order to use CUDA. I did so via Nvidia website and installed the driver that was suggested: the 270.61 version. The update was, or appeared to be, successful but after rebooting the pc the problem with the video signal started.

There was no way to use a restore point, because none was old enough, so I have installed an older version of the grdriver but it did not solve the problem. My last attempt, this morning, was to install the latest version of the graphic card driver - the 275.33 version - but the installation fails. I have also tried to perform a fresh install of the driver, following some advice found online, but whenever I try to perform all the operations suggested the pc shuts down.

I'm quite clueless and frustrated now, and before I do anything else I am wondering if anyone can give some advice. Thanks in advance.

Here's what to do, boot the pc up, and go to device manager, find your graphics card and uninstall (if it let's you delete the old driver then do it), reboot and let the driver install on it's own. Now after that's done, confirm the driver works and keeps the display on, if it works then update your graphics driver using the geforce drivers(not the cuda), and restart. Hopefully it should be sorted
