I have a new computer which for the most part worked fine for the first week. Then it would start crashing often and make it difficult to do anything. I reformated several times and it didn't fix anything.
Right now I think that maybe the RAM is bad because I think the errors are memory errors.
I know of memtest86 as a memory tester, but I don't have a floppy drive or a way to burn a bootable CD so I can run the program. Are there any memory testing programs that can be run in windows?
I don't really know which programs to trust on the internet anymore.


Edit: I forgot to mention anything about the specs. I don't know what will matter, but I imagine knowing that it is XP would help. If anything else needs to be known, just let me know as I am sort of lazy (more of tired of the computer) right now.
