HDDs are WD400YR (x4) 3 are connected: 1 - OS, 2 - RAID 0 through Windows7 the 4th is a spare.
+ 2 ADATA SSDs that are RAID 0 on there own with a RAID card.
Motherboard: ASUS M5A97 R1.02
Ran diagnostic through GParted. When running the diagnostic, the HDD just spins at a low RPM, can feel it and hear it. Did diagnostic on all four. Thought it odd to have all four go dead.
Took the original HDD off, put spare on, still same thing: spins up then clicks, spins up then clicks.
Thought it may have been the 500W power supply. Installed new 750W power supply. No go.
Took the RAM off, reseated, still nothing.
The black screen, when starting up, shows the two RAIDed drives that would be attached to the OS, and shows the Two ADATA RAIDed drives, then gets stuck at the ADATA screen. Not sure if this makes sense... if not, will see about clarifying later.
Even disconnected the ADATA drives leaving the lone OS drive, still the notorious hum and click.
At work we would just order a new PC and be done with it.
Anyway... Think it may be the mobo?
