No response when 0 free memory (all cached)

Hi logicearth - from my limited knowledge normally when my PC freezes for a period I go into Task Manager & it would show CPU 100% or so by 1 or more processes. But this time it does not. It was like 1% CPU. However I noticed that if I continued to try to use anything while it was frozen then CPU would spike to 100% while doing so (just during keystrokes, etc) then would drop back off again. Was not sure if that was relevant or not, so included in the post. It only shows 100% when I was trying to do more while frozen.

CPU 43, HDD 33 - these are OK aren't they?

Those temps appear to be OK. If you have a separate graphics card you should see a 3rd temp for it.

If that temp is consistantly higher than about 100C I'd want to check it out.

Thanks marsmimar - looks like I don't have temp for GPU.

That's strange. Don't have an explanation for that as Speccy is pretty good compiling info. Looks like you're missing some additional info as well.

Well I've just been surfing net for hours now & cached memory has eased back off. It sits at about this 4-5GB more often than not when we are not doing much other than net & email. So if Win7 is happy to sit with 4-5Gb cached & 2-3Gb Free most of the time, why does it then cache 'more' memory when we are trying to use more.... Seems odd..

If you click on the Resource Monitor button you'll get a better picture of how your memory is being allocated. 7 seems to anticipate what various programs might need and allocates memory accordingly. From a Microsoft forum: "...empty cache memory is wasted cache memory."

how to reduce memory usage

First and foremost, are you using any kind of 3rd party program for memory management?

Can you install another version of PSE8, just to see if there's an issue with the program? Like a trial, or if not, maybe you have an older version?

This may seem unecessary, but just because this is so odd, I would do these two things, just for the heck of it because they're so simple.

sfc /scannow

Then a smart and/or quick scan using an anti-malware/spyware tool, and then a second quick scan of just the program folder for PSE8. Very unlikely, but takes 2 minutes so why not.
