PC POST/booting issue – win 7, constantly rebooting
January 25th, 2020
Ultra 790i Motherboard 3.2Ghz Duo Core
8GB RAM 250GB SSD 1TB HD
2x Nvidia Geforce 250 GTS (1GB ea, Crossfire)
850W PSU
I have ran the system without the SLI first as i know i have to install the drivers in order to allow SLI, the first thing i noticed was a 2 beep POST on the start up but the diagnostics display showed FF meaning no errors. I’d then attempted to install windows 7, i popped the disc in and booted to CD in which case the installer box didn’t pop up at all, i then tried it with a USB which the same issue happened. I then removed the SSD and put it into another computer with the same CD and installed windows 7 perfectly fine, i then ran a repair console as the windows OS was just rebooting when loading. As the repair didn’t work i then tried SysPrep which also failed after building the boot mgr. Does anyone have any solutions?
Firstly installing Windows to the SSD on another PC would never work when you move the SSD to the new build as installation is motherboard related.
Connect the SSD to the other PC and format it, reinstall it into new build, disconnect other drives until later. Go into BIOS Boot tab (not the quick select Boot order) set the SSD as the primary boot, exit and save. after restart use the quick select boot order (F8 or whatever it is on your PC) and set it to boot from disk or USB, depending on how you are installing. Install. After installation shutdown and connect your other drives and set whatever drive letter to each if required.
Not really a good system to have an SSD. Its really bad if you don’t have AHCI.
is correct, operating system is motherboard bound, you will have lots of issues, its like using a cloned system. If the desk/usb is prepped well and the USB/optical drive is working, all you need to do is set the boot order. And make sure you set, AHCI or SATA, not IDE emulation if possible.
Any of these settings change during a bios reset, will cause the system to be unable to boot.
You will waste hours figuring whats happened, so keep this in mind.
Thank you both for your replies, i understand the fact it wouldn’t work just swapping the SSD over hence why i tried the sysprep and rebuilt the mbr, as i guessed that isn’t a solution. The main issue i have in this case is the fact that even when i try to install windows through USB/CD in the built pc it’ll load the disc (after boot select etc) and the loading screen will come up for the installation, the point it stops at would be when a window is meant to pop up for the installation which it doesn’t show (only the background shows). So for some reason i can’t install windows, even after trying at least 3 different ISOs.. :/
This is likely due to motherboard incapability, SSD does cause complications for windows installations if windows detects that the connected hardware is too new. The Sata controller must be incapable.
Thanks for that point, I’d removed the SSD and placed the 1TB SATA HD as a primary drive and the issue still persists.. very confusing at the moment.. just a shame about the SSD too as it does recognise it and I have run tests in the bios to see if everything is running correctly.

Second hand parts?
Could be a faulty motherboard altogether.
i had purchased new and the onboard post display shows no errors apart from the two beeps which could be when it’s running the tests prior to booting.
Try this one:

I suspected the motherboard didn’t have drivers as it was a really old one, it came before Windows 7 I think.
Windows tend to not install if hardware incapability comes.
That’s talking about RAID array, this can be set up through the on board bios but hasn’t been enabled, sounds a stupid question.. can I still attempt to install drivers via the cd without having the OS

At first I did think it was cause the jumper switch was set to flash rather than normal.. but I changed it back and no difference still. Such a headache :@
2 Short Beeps.
Your computer has memory problems. First check video. If video is working, you'll see an error message. If not, you have a parity error in your first 64K of memory. First check your SIMM's. Reseat them and reboot. If this doesn't do it, the memory chips may be bad. You can try switching the first and second banks memory chips. First banks are the memory banks that your CPU finds its first 64K of base memory in. You'll need to consult your manual to see which bank is first. If all your memory tests good, you probably need to buy another motherboard.
