My ageing (late 2009) Windows 7 desktop PC has started doing something odd of late. If I restart it, or shut it down completely, it does not restart properly - it gets up to the black screen with 'Starting Windows' at the bottom, but the Windows logo animation does not begin.
However, if I leave it powered down for at least 2 minutes (1 minute is apparently not enough), then on my next attempt it seems to always boot without any problems.
I tried booting it in safe mode when it wasn't working, and it gets as far as loading 'classpnp.sys' - which from a bit of online research, often suggests a problem with the HDD, but I ran CHKDSK and got no errors.
Although it's getting on for 6 years old now, it's not been used that heavily.
Specs: - motherboard: ASRock G31M-S - CPU: Intel Core 2 Quad Q8200 with integrated graphics - RAM: 4GB DDR2 - HDD: 500GB Maxtor (from memory, I think just a basic 5400 RPM)
