Problem with video during boot-up & wake-up.

I have an Asus P5Q SE Plus motherboard, and everything was okay for the first 2 months, after which I started to experience problems with getting the monitor to switch on; at boot-up and wake-up it now takes about 10 minutes for the monitor to come to life.

I had been using the monitor (Samsung SyncMaster 2043BW - 18 months old) on an older Pentium 4, 32-bit Win XP system with no problems. However, I assembled the present Windows 7, 64-bit system at the start of 2010 and experienced no problems for about 2 months, until the present problem appeared, where the monitor refuses to come to life for about 10 minutes after boot-up and wake-up. At boot I get one bleep, fans, lights, mouse and keyboard fire up, and I hear the Windows welcome sound - and then the waiting for the monitor

I've updated the BIOS and reset the CMOS by removing and replacing the battery, but that had no effect.

OS: Windows 7 Professional
Graphics card: Asus EAX550GE/TD/256M/A
RAM: 2 x 2gb of Kingston PC2-6400 CL5 RAM (part no. KHX6400D2K2/4G)
Monitor: Samsung SyncMaster 2043BW - approx 18 months old.

Any help would be appreciated.

  1. Okay, forget it. It's a monitor fault and Samsung are going to replace it under their 3-year warranty.
