Firstly I might suggest you should check into acquiring some single floor accomodations.
Beyond that, a step by step examination of each connection of each component - concentrating particularly on the motherboard itself.
If nothing is obvious, cut back to barebones. mobo, cpu, mem, vid card, hdd.
Try to access the BIOS and check that all settings are correct.
You could attempt to boot from CD. Perhaps a format and reinstall could kick that HDD to life? All you could do is try? Perhaps an fdisk /MBR ?

Good luck with it!
