Having just added a new graphics card, sound card and DVD player I was feeling pretty happy with my rig. Then today It started to start up fine but when I put the arrow over the start logo the hourglass would remain for about 2 minutes . Anyway I deleted some clutter and notices that I was only showing 256 ram sb 512 So i removed the graphics card to get at the memory (bad design) and swapped it around, still 256 tried again (taking precautions as per the sticky post above) then nothing I could not even get to the bios. Beep beep beep and the LED shows C1 (auto detect memory.) I must say that as the memory went into the slots there was a crunchy gritty sound. All looks very clean. As I need a machine I moved my HD as a slave into this old machine and also the memory which shows as 512 and will hope for your help. I have put in an old graphic card 128 sdram that I know is OK but the same result. I cleared the CMOS but it did not help. Any Ideas Spec.
