No I have left psp for the moment.
The corel forum reckoned a 90% spike on pspX1 can sometimes be expected.
I've got over 4gbs. in My Pictures, and they load up in the psp organiser.
Sorry I havn't got back to you. Hopefully problems will clear up, otherwise you're in no-man's land and need to do some serious trouble shooting. PCs are complicated and there's lots to go wrong.
Hopefully you're not using a 64bit version of XP or Vista, as these are frankly not ready for prime time and are generally unsupported by hardware manufacturers. If you are you're on your own.
Some older software doesn't play nicely with new-fangled dual core processors, but on a fresh install that shouldn't be a big problem.
It's a while since I played with windows, perhaps someone can help with directions, but there should be the facility to turn off or down hardware acceleration for video and sound which may help narrow things down.
It's probably worth checking out the Device Manager to see if there are conflicts or failing that unplugging anything that isn't essential (including internal stuff)
I must have been running for 3 days now without a lock up.
It would appear (at the moment anyway) that the PC plug to the 5 socket mains supply was either not pushed fully in or has dirty contacts.(I exchanged the position of the pc plug with my joystick device)
So enjoying my new computer after three months of hard labour that I have not put the plugs back to their original position.
Must do a bit of flying and see if the joystick keeps me on course.
