I have been running windows 7 for the last year without any problems. Yesterday I thought I would try windows power saving mode. I went into the control panel and selected, to sleep the computer after 15 minutes of inactivity and power off the screen after 15 minutes of inactivity. Once I had done this I was away from my computer for around 20 minutes, however when I returned the system would not instantly power back on. I was forced to turn off the computer at the wall and try and reboot. When I first rebooted I immediately got the Asus P5Q splash screen, followed by a message saying Asus Express Gate is not installed. This is Asus instant boot environment, which I know I have never installed or ever used. I then went into the bios and disabled Asus Express Gate. I then rebooted again and immediately got the Asus P5Q screen on power on, however this time without any message about express gate. After a couple of seconds a black screen appeared saying: Marvell 88SE61xx Adapter – Bios Version 1.1.0.L69 – No hard disk detected!. Despite this it does boot to windows, however when windows loaded there was a problem that no drivers were installed (printer, network etc) I then turned off power saving features and rebooted again. On reboot the same 2 screens appeared (apart from express gate message) however this time windows loads with all the drivers. Despite disabling the windows power management system, on boot I always get the Asus P5Q splash screen and the black screen saying no hard disk detected. Previously I just used to get a standard black booting screen. I have done a few virus scans, however these have not come up with anything. I am thinking maybe it is a hardware problem as I get those screens immediately on booting? However it seems a coincidence this occurred at exactly the same time as me changing the power management settings? Also I don’t understand why the first time I got the Express gate problem message? Does anyone have any idea what is going on? When I get into windows everything is ok.
