Three things you can do:
1. Check if the disk works on another PC.
2. Remove all unnecessary hardware. That's the GPU and 1 stick of RAM.
3. Reset the BIOS to defaults.
If it still doesn't work with known correct disk, minimal hardware and a default BIOS, start replacing hardware until you found the culprit.
You might like to try to boot from, or even install, Linux, just to see what it does.
I just assembled a "new" PC out of some old parts from a couple of other computers I took apart (plus quite a few new parts to fill in the gaps). I am trying to install Windows 7 (64-bit) and after startup, it goes through the POST, starts spinning the DVD, says "Windows is loading files...", displays the "Starting Windows" logo screen only momentarily, then restarts and starts all over again.
I'm caught in this loop and don't know what to do to actually get Windows installed!
Some (perhaps) relevant details:
-Intel BLKDP55WB motherboard
-Intel Core i3 - 530 CPU
-8 GB (2x4GB) DDR3 1333 Mhz RAM
-1 TB Western Digital "Blue" SATA HDD
-MSI Geforce GTX 650 Ti GPU
-Rosewill "Stallion" 400W PSU
I'm able to get into the BIOS and tool around just fine, and all the components seem to be recognized. I've changed a handful of settings - boot order, SATA mode (set to AHCI), disabling network boot.... etc. Nothing seems to have worked so far.
Any help would be greatly appreciated!
