I have a brand new system that I just built. I put in the Windows 7 DVD and it booted right into the installation with no problem. I answered the questions and started waiting while it was going through the multiple reboots. After a while, I looked over and noticed that it was stopped on "Loading operating system..".

I tried the basics like reseating all the components and powering off the computer, but with no luck. Then I tried pressing [del] to get into the Setup. It would tell me that it preparing to go into Setup, but never did! I experimented with hardware and found that removing the SATA cable from the motherboard at least let me get into the Setup. Tried switching cables, SATA ports, and hard drives with no better luck.

Any ideas?

So you can't get into the BIOS at all by hitting Delete during POST?

Have you ran Memtest on your RAM? Lock ups can be a sign of bad RAM, always good to start with the basics one at a time!

I kept trying different hardware. When I removed the 2nd memory module, everything started working! I switched the module around to make sure it wasn't the memory slot and it wasn't. Thanks for the help.
