Hello there. I am having problems with a computer I built for a friend. The problem I am having is this: From a cold boot, the BIOS POSTS and then when it is finished posting (no problems seen) the screen goes blank as if it is ready to go the spot that says ...Loading OS.... or something like that, but it never does, there is just an underline cursor on the top left of the monitor that is blinking. If I hit the reset button on the case, the BIOS POSTS again, and this time it comes up with the ..Loading OS... message and Windows 7 then launches and everything works fine. This double boot scenario also happens if I am in Win 7 and Restart the computer....POST then blank screen with cursor in top left, hit reset button, all boots fine and runs fine. I have run Prime95 just to check some stability and I also ran Memtest86+ to check the memory and nothing is showing up as wrong. I am not sure why I have to "double boot" with the hard reset on the front of the case.
System:
GA-P55A-UD3P rev 1.0 using F14 Bios (Latest)
i7-870
OCZ DDR3 Gold OCZ3G1600LV4GK - 4 gigs of memory in a 2gb x2 config
Seasonic 620W p/s
EVGA GTS 250 1 GB video card
Samsung F3 Spinpoint 1 TB hdd
Win7 Ultimate x64 OS
To add more to the story, I live in the US and built it for a friend in the UK. The power supply is auto sensing (no switch needed to set to 220V) dual volt and 50-60 Hz. When I build the system in the US, I had it up and running fine with Prime95 burn in for 12 hours and Memtest86+ running with no errors. I did not have this double boot issue. I mailed the system to my friend and it needs to be "double booted". Memtest86 is clean and Prime95 run clean and while the OS is up and even if it goes to sleep it operates fine. But the second he reboots or powers off and cold starts overnight, he gets the double boot. I had my friend go into the BIOS and check the settings for the CPU and memory and all those setting are still the same. The memory is running at 1600 Mhz with a x12 multiplier and that keeps the bclk at 133 so no overclocking to the CPU. The voltage of the memory is set to 1.64V per memory spec. The Vcore voltage is at 1.275V. Again, these settings were stable when I built it with no double boots.
Thanks for any help/advice.
