My page file was in the dxdiag: Page File: 751MB used, 5232MB available.
I use Norton for my A/V and Spysweeper for my A/S.
All Window's Drivers are up to date.
As for software, other than an occasional clean up app to solve this problem, such as a freeware registry fixer, nothing else. Usually downloaded once a week or so.
Hardware: In July I added two gigs of RAM to my then existing one gig.
A Radeon x1900xt 512 gpu, all drivers updated on that.
And lastly, a new psu, PC Power and Cooling Silencer 470 W.
How do I find running processes?
