I'm running an ASUS A7N8X-Deluxe mobo. Had a freezing problem the other night and upon rebooting, I get a system failed memory test error message. The system will not boot up at all. I just reinstalled new memory, and tested the old stuff in another puter and it worked fine. Any ideas what to replace? I can't even get it to boot up a floppy or into the bios. Thanx in advance.
