Must be one of those days, switched the desktop computer on this morning to do some drawings for the laser cutters and the CAD program got slower and slower.
Re booted and it hung on the splash screen.
Get it checked and the chip has died, modern chips won't fit this motherboard so new motherboard and chip later it won't read the original raid array on the drives.

Now got to rebuild the raid arrays and hope it doesn't loose any data. Laptop is working but this doesn't have email enabled so new drawings can't be sent.
