GPU memory test: how long?

[chattenoire]

How long does it take to complete analysing a graphics card memory?

The video card in question is Nvidia Geforce 9600 GT, it's being tested by the utility called SiSoftware Sandra, and the test has been running, like, 25 hours. Is it normal? (The settings are default, so it shouldn't be an endless cycle...)
Unfortunately, the software does not show the progression of the test.
I believe the OS is not frozen, although the monitor is; the mouse led has its regular red shine when the mouse is not touched. So, the devices aren't responding but the system is probably running.
How safe would it be to force the shutdown / unplug the PC; could it damage the video card? How long can a standard PC be working?

It doesn't sound normal. You could Google that card's specs, and it is safe to turn off the computer. As for how long a PC can run, for example, mine never stops.
There was a program I had found once that told me directly the memory of GPUs, though I don't remember it now. What you're using is probably a stress test to see how high the temperature and how slow it gets, which never stops unless you stop it yourself.

It runs til you terminate it...

So does MemTest.

All right, the PC having been rebooted, nothing seems to be out of order, except for the txt-report breaking at the place it should show the test results at. I'll try some different testing software, then.
Thank you for the answers!
