Frustrating graphical issues with Netradiant, issues with textures not appearing

Try running GBoost. It will shut down unnecessary processes. Also give CCleaner a run.

Also, about those images you posted, what were you trying to say? That you can't access the desktop?

Those images were the result of your advice. i.e still at square one with the problem regardless. And ive used those programs in the past, other than essential processes ive tried the program with practically nothing going on in the background to no avail.
