Run the Windows Memory Diagnostic Test for both passes. If probs, run Memtest86 CD X 6.

Have you checked Dell's Downloads page for your model for a more recent BIOS update?

You say you are "running custom install" so I assume it is from Vista. Have you tried booting the DVD for Custom install?

Try resetting your CMOS: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS

Recovery might be disabled by Win7 install, so make your Dell recov disks, or save externally a backup image of Vista. Then deep clean your HD with DBAN to overcome any boot sector corruption.
