[QUOTE=ChristineBCW;2656963]Jim, one more idea - do you have a bootable Linux or Windows Install CD-DVD? ANY bootable version will do.
Open up the case, unplug the power and SATA from the HDDs. Pull out one of the Mem Sticks, too. Then, restart the computer and let it sit on the Install Disk. Just sit there. Hours…see how it behaves.
If it continues to reboot, replace the Single Mem stick with the other.
If it still reboots, then you’ve got (1) Make sure all heat-sinks on the chipsets are attached…
(1) ReFlash The BIOS…
(3) Reseat the CPU (ugh)… this is probably #1 likeliest cause, by the way. Biting the bullet and doing this might solve all. Just pull it out, clean off the edges, stick it back in. Nothing fancier than that.
After that… “bad motherboard” would get my vote.[/QUOTE]
I agree with Christine, MB, Processor, and Memory this is the basics if it doesn’t run solid here you have a problem. This Rig should have been fixed a long time ago. That’s why building computers takes time and patience. You start from the basics and work your way up. If the basics are not solid, you stay there until the problem is solved. If you don’t build a computer properly, you end up with what you have now, an unstable mess.
