I just built my system a few weeks ago and it will run fine for days then i start getting random crashes and errors in alot of my programs. Wondering if maybe i have a bad stick of memory or if something else is messed up.....What tools could i download and use and how to i use them? Id like to just run something overnight or something that can test everything and give me some sort of report so i can figure out if i need to just reinstall Vista 64 or if its a hardware issue...
