An update
I read something about dust affecting electronics particularly ram
chips, so I pulled the graphics cards and ram cards and gave all a
good vacuum and wipe
I also read that there are 2 buttons on a logic board - a reset and a
diagnosis button

Pressed reset button and then put graphic cards and 1 ram riser card
back plus put hd 's in different trays.
Rebooted into Mac OS 10.5 on hd2.
Plugged in my lion installer USB stick and started process of
reinstalling on hd 1
Took like 90 mins and it rebooted into lion on hd1 - yippee
Now I'm downloaded 10.7.5 combo client update( 1.9 GB)
Hopefully all will be okay !

Howdy
Yesterday my macpro 1,1 os 10.7 had a freeze - the 2nd screen got
thin red lines running across it in both directions - diagonally I think
Upon force restart I got blinking white start button- hmm I
understand that's a ram error
Sorted out blinking white light by removing ram chips and then
progressively reinstalling in pairs -
Upon restart boots to grey screen
Can reboot into 500 GB 2 nd hardisk ( os 10.5.8)
Other combinations-
Safe mode- shift key ( gets to about 25% left overnight
Recovery - r key
D key
Option shift P R keys
All Get grey screen freeze
Can boot into system select - option key
Shows hd 1 - 1 tb OS 10.7
Hd2 - 230gb is 10.5.8
HD recovery
Backup efi ( time machine disk ?)
Lion efi ( when USB Instsller stick plugged in)
Except for hd2 all seem to get stuck in a loop of grey screen
I removed hd1 and plugged it into MacBook and did hardisk check via
disk utility - says all is okay (65 GB free)
Does this likely mean the OS lion is corrupted and needs reinstalling
Can I reinstall lion via the MacBook ( I have new tech USB drive
adaptor set).?
Also I gather I need another hardisk - can I use a WD drive from an
external hardisk, or do I need to buy an internal sata drive? Or an ssd!
Appreciate any advice.
Specs are
2006 macpro 1,1
Hd1 935 gb Mac is lion 65gb free
Hd2 Mac OS leopard 232 gb 18gb free
Ram - 2x 512, 2x 2, 2x 4=13 gb
ATI Radeon hd5770 slot 1
Nvidia gforce 7300gt slot 4
2x 23" Apple cinema displays
