Do I have a hardware problem somewhere?

[psam3]

I'm quite sure it is, but the question is what. I recently built a new computer, an ASUS motherboard, http://www.newegg.com/Product/Produc...82E16813131354 an AMD Athlon II X2, http://www.newegg.com/Product/Produc...82E16819103687 2 gb G Skill ddr 2 800 ram, and a 250 gb Seagate hard drive http://www.newegg.com/Product/Produc...82E16822148261.

The problem starts when I try to install an OS. Everyone that I have tried to install has messed up somewhere. When I try to install Fedora 11, it freezes on the hard drive partitioning screen and will NEVER make it past that point. When I try to install Windows XP I get an error saying "Cannot boot from CD - memory overflow problem" or something similar. When I try to install Vista, the CD will not boot at all, it doesn't even act as if it's reading the disc. I managed to install Ubuntu once, but after about 30 minutes of use the screen went white, and up until the time prior to that the screen would flicker randomly every few minutes. I did not try to restart it because I don't really want to use Ubuntu right now. My goal is to install either XP or Vista. I am thinking that maybe there is a bad piece of hardware somewhere, but every single OS points me in a different direction. Perhaps the motherboard is bad? Or maybe nothing is wrong at all and I just set something up wrong. Anyone have any ideas? Any help would be truly appreciated.

Thanks

The Ubuntu CD includes a boot option for memtest86+. Try running it.

Also, if you can, try replacing memory/CPU etc. with known good parts to find the culprit.

Edit: It's just called "Test memory." Guess i'm too used to old CLI type bootloaders.
