The problem occurs when im installing a game, after a minute or two while its installing my memory usage will start increasing and it does this all the way up to 99% where it will sit until i reboot my pc.
Now this only happens when i install a game, i can do ANYTHING else and its fine ie play games, encode videos, move files etc etc all fine.
Right, things ive tried so far...
First thing i did was open task manager and see what was using up the memory unfortunately there wasn't anything there that was using it even so i still shut down every single process and it still was at 99% memory usage (btw this takes forever to do when your memory is maxed out)
I tried running sfc/scannow (nothing wrong)
Next thing i did was run memtest 86+ all night (10 hours) No Errors
After that i ran prime95 blend test all night (10 hours) No Errors
Then i ran disk doctor on all my HDDs and fixed any problems it found
After all that didnt help i decided to format my pc and start afresh so i reinstalled vista 64 thinking this has got to fix it, but no it didnt.
This all just happened out of the blue after my system was running fine for nearly a year.
Im all out of ideas guys so please, if you think of anything please post.
Thanks for reading, take it easy.
