Asus P5QC Express gate not installed, cant boot pc

Hello, first I would like to apologize for my orthograph im french canadian so my english isnt so good

I tried to boot my computer yesterday , and nothing appeared on the screen, power seemed to work great, all my vents
were on, and the little green light on my motherboard was on too, but my mouse, keyboard and monitor wouldnt respond.

I dont know how it happened but today i have turned on my computer succesfully. The first thing that appeared on the screen was Express gate not installed error. So I reinstalled my drivers then at the end of the day i turned it off. But today, same problem and this time I cant get it to turn on again.

I have a

Asus p5QC motherboard
Intel duo core 3.0g processor
ATI 4870 (512mb) DDR5 video card
OCZ 4g DDR2 dual channel kit memory

plz help me out im kinda noob with hardware. thx in advance.

I am having the same problems as the OP. I built a core i7 system with an ASUS P6T MB and 6GB of OCZ Gold RAM. Express Gate has worked fine until recently it displays an error that it is "not installed". Then the system proceeds to tell me that it cant find the operating system and i need to reboot. Sometimes though it gives me the Express Gate error and then it can boot windows. I have also been having problems with my system randomly freezing since day one. I believe this is also MB related because i have tested the RAM extensively and i really doubt the i7 is bad. Any help would be much appreciated.
