Since a couple of days I have a very weird problem with the following config:
Asus P5K-E/WIFI-AP
Corsair TWIN2X2048-6400, 2x1GB, DDR2-800
Intel Core 2 Duo E6750, Dual Core, 2.66 GHz
Asus EN8600GT SILENT/2DHT/256M
Corsair CMPSU-520HXEU, 520W
Samsung SP2504C, P120S, 7200rpm
At the very first "morning" startup, the pc does not want to boot, the hdd led does not show up.
No display.
Reset an retry will not help.
However, if I switch off manually the Power Supply, wait a little, re-start then it boots complaining about "overclocking failed".
I enter the boot setup, do no modification, save and exit, no problem at all!
ps: when it manages to boot, i observe that it does it in 2 times: I see my akasa fan controller showing up, then suddenly off during one second and eventually starts up. I don't remember such a behavior before.
Is this possible there's a defect on the MB?
Many thanx and sorry for my so-called english.
