I would double check that the memory is properly seated and that the latest BIOS revision(s) mention anything about Windows 7 fixes, or support for it.

Also, check to make sure the laptop is using ACPI in the BIOS.

if you have faulty ram its likely to stop half way through and turn your laptop into a brick, test all hardware first (memtest etc), get yourself a copy of UBCD4WIN or Hiren to test the hdd etc

also if your laptop was designed for Windows XP then chances are 7 and Vista are not supported

BIOS issues are things that are issues from day one, not months and years later - its NOT the bios
