What makes you think it is the heatsink? Are you getting high temperatures?
I listed some suggestions:
- Check if the Back-to-BIOS button is enabled. http://downloadmirror.intel.com/21156/eng/dx79sr_TechProdSpec03.pdf (page 46)
- Reset BIOS to default settings. You may also try removing power and CMOS battery for 20 minutes.
- Test the board out of the case with minimum components on a non-conductive surface.
- Update or recover BIOS. Desktop Boards — BIOS Update Instructions
everytime i start up i have to reset bios to default settings or rather it gives me the option saying i have no readable media. when i put the new motherboard in( replacement board of the exact same board i previously had in) does it mean i have to reformat my hard drive and set up everything new again? or should it just pick up where my old configuration left off? because i'm noticing that it is reading that my hard drive is there but will not boot from it currently.
anyways the reason i know my heatsink or something messing with my heatsink is amiss is because everytime i start up the computer the processor and heatsink gets hot, and the way my heatsink is set up is it runs water through it's self like a radiator to the fans on the back of my computer and cools the water there then returns the cool water back to the processor, and when it does this it makes warm air come out the back. at the moment though i'm getting cold air and when i feel the part of the heatsink that is touching my processor it is hot to the touch to an unhealthy degree. due to this i haven't been able to explore fully what my computer is currently capable of in fear of destroying either my processor or motherboard due to overheating.
i was having an issue determining whether this was due to the usb port (which is where the pump plugs in) not powering the pump or if the pump was just bad. the heatsink lights up for like .5 second and acts like it's going to work then stops. i'm hoping this is due to a short in it somewhere and not something with the motherboard that i will, yet again, have to send in for a replacement.
The operating system should be able to boot if the hard drive came from the same motherboard model. The only thing is, you will need to match some BIOS settings, such as: SATA controller mode (AHCI, RAID), UEFI, and legacy boot options; they will need to be the same as they were in the old motherboard.
