Random Shutdown?

[leesiulung]

My computer randomly shuts down now and I'm not sure why, after I changed the graphics cards. Unfortunately I no longer have the old graphics card to re-install.

I noticed the temperature of my CPU go to 72C degrees after shutdown with stock setup, no overclocking. Is that normal?

The CPU fan is functioning, so I'm not sure what the problem is. The setup:

XFX NF590a
AMD Athlon X2 6000+
XFX Nvidia GeForce 7600GS (passive cooling)
Windows Vista Business

Any suggestions?

Your CPU is running way too hot. I'm not sure which X2 6000+ you have but even the highest temp rating is 70C.

How warm was the CPU running before you installed the card? What kind of case do you have? I doubt the passive card is making your CPU overheat but they're meant for cases with at least decent airflow...and/or your CPU heatsink/thermal compound might need to be redone.

I believe I have t he 65nm, 512KB L2 cache version rated at 62C.

My case is an Antec P180, but it shut itself down even when the case was wide open. The only thing I can think of is the CPU needs some new thermal compound, but would the temperature increase that much with old thermal compound or even without?

I wonder why it runs so hot, when clearly the fan is working?

Improper contact with the heatsink base will be my guess.

I will try and re-align it, but I already tried once to no avail. Really odd....

It's not so much the alignment as it is how cleanly the thermal compound is making contact between the processor and the heatsink to conduct the heat (i.e. no air bubbles, human oils, other particles, etc). Make sure whenever you reseat the heatsink that you ALWAYS clean both surfaces with isopropyl to remove all the old compound before applying new stuff, and make sure you apply new compound per its instructions.

I would have to agree with IGemini.. most likely a mount issue.. simply not tight enough? Or improper application of thermal paste.. (too much is no good.. just a drop is needed, the size of a grain of rice.. and then spreads it with a credit card , etc...)

You mentioned you're running stock.. but double check your voltage settings in your bios to ensure your vcore isn't set higher than it should be.. Simiilarly.. make sure you're not running any type of software via windows that may be overclocking your settings as well...

... but i suspect its the installation of your heatsink that's the issue...
