Built a new comp for my friend using an Asus P5Q and a Gigabyte GA-EP45-UD3P ( Will get to that one in a min)
Intel Q9550
Asus P5Q
Kingston HyperX 4gb dual channel PC8500 5-5-5-18
Sapphire 4650 w/HDMI out
built it at my place...ran perfect for a day..he took it back to his college ( its not a current issue because he has been using an APC UPS system)...
Ran for 3 days but then he normally did a restart and now it may boot into windows sometimes but it will constantly restart within 10 seconds - 3 mins...most of the time its less than 10 seconds.
we only had a 460watt cooler master and someone else suggested a bigger psu...found a Corsair TX750 on sale and used that...put that one in and it ran for another 20 hours without a problem ( and i even ran burn in tests for over 2 hours (could only do that that short a period of time because i had to drive 2 hours to get to his college and had to get home) on it to stress all the components)....he woke up in the morning the next day and he restarted ...Bam...started doing the restarts again...
I drive up there again and swap out the entire motherboard to the Gigabyte mentioned above...this one starts restarting within 2 hours of the install...it won't even get past the POST screen before it restarts a lot of the time...
to answer your most obvious questions...Yes I, when the computers were running, updated both boards to the latest bios...The Ram is fine...i tested both boards with that kingston ram and the DDR2 PC6400 Corsair 4gb DHXC4 which i run in my computer
and have been for a year or more now with no problems. New Hard drives and cd drives...doing nothing special with it...it does this with the HDMI out functioning or not on the video card...even did it when i restarted without the video card even installed.
i installed the cpu/ram in my older Abit IP35-Pro mobo and had no issues...The gigabyte would not even get past its bios screen with my old Q6600 and ram in it but the Asus booted up just fine with it in..
The Cpu fans are going and when i ran the stress test , the cpu didn't get above 48 degrees...( he keeps it freezing in his dorm)...
I want theories/silly suggestions / anything...this is stumping me.
