Windows Laptop Won't Boot

When we pressed F8 and booted we got a message that said DQS training failed on previous boot, Revert to slower DRAM speed.  Press F1 to continue.

It doesn't boot up at all. We hear the fan but won't boot to operating system.

Windows 7 Ultimate. MSI laptop.

Turns out it seems to have been a RAM slot gone bad. We took the one RAM module out of the slot it was in and put it in the other slot and it booted.
I'm guessing this a gaming laptop as DQS is normally used for 'overclocked' parts
Enter BIOS
Go to advanced tab and there should be an option for DQS in there, try setting it to Auto or Default.

Or try a BIOS reset to default and see if that makes any difference.
Have you recently added new hardware to the laptop?
