about an hour ago, I ran the Windows Memory Diagnostic test on my laptop (I was in Windows, chose to run it fsr and let the computer reboot). It went through both passes with no errors. It then went to boot up Windows 7...and just didn't do it. It hanged on the "Starting up Windows..." bit right before the logo appears and eventually restarted itself. I got the Windows failed to boot error and I immediately went into repair mode, which did absolutely nothing. It was at the Attempting Repairs bit for well over 10 minutes when I shut the computer off (probably not a good idea). I turned it back on and this time, I chose to boot Windows 7 normally and voila, here I am. I didn't get the Diagnostic Memory report, though...
I found it strange that it refused to boot Windows once and but works now. Should I be worried that my machine is going to fail soon? It IS a 4 year old laptop.
