Can you connect the monitor to another computer with a different cable to check it isn't the monitor or cable. Or connect the Mac to another monitor to try to eliminate causes.

Have you reinstalled the pre-patched Yosemite yet? You said it was working before upgrading to 10.10.5 so worth trying. The screen flash and failure to install may not be the same problem.
Yes i changed the monitor and the cable (I have another Pc in the hause ), the monitor and cable ok.
yes i repached the new usb yosemite.. the install it's starting , but frozing ..

This happens to the best of us. You are clearly doing something wrong. Follow Hennesies instructions very carefully and you will be up and running.

If it id's as a 8800GTS 512 it is a card we created.

Should be fine but you never know. We made during 10.6.8 but Lion broke something. Had to send out a reflashing app for Lion. Possible that driver got broken, they don't always test for every version of cards. For longest time the G80 "GTX" was broken in driver but soft strapping it to "Ultra" fixed it, a single device id got left out of driver.

Before we developed the actual GTS rom, everyone was flashing that card to standard 8800GT as soft straps write final bit of device id. Can even be done in OSX Lion by clever types. Would remove card as issue. (But card slower, still fully enabled G92 but lower clocks)

Question for those with an Xserve 1,1.

I found one on Craigslist at Johns Hopkins University that is already running Yosemite for $100. It has dual E5320 processors. What kind of performance might I expect from this machine for a Plex server?

Edit: never mind it probably won't be enough performance per watt to make it useful.

Is there a pre patched .dmg/Install (Yosemite for 32bit Mac 1,1) somewhere??? Would be easier..........

Thanks man, this post is so long now. Hard to fine stuff.

Whats the best method to install? Bootable USB? Using Disk Ute on Diskmaker?

Thanks!

Making a bootable USB or DVD always worked for me. The most trouble free is to create an 8GB partition on an internal HDD and restore the pre-patched dmg to that.

Did you have the PikeYoseFix installed? If not then you will need to replace both boot.efi files again.

If you update without having installed Yosefix the boot.fi files will be overwritten by the update and your Mac will not boot. Once installed this fix ensures the files are not overwritten and you can update to 10.10.5 from the App Store without any problem.
