PowerMac G5 wont boot, help???

1.6 ghz 4gigs ram 3rd party power cable, new psu could be bad... no hdd. When i press the button on the front, the blue led comes on only as long as i press the power button.

What may still me salvagable on the Mac, or is it repairable and if so, what is needed to repair it?
Thanks for any help, feel free to ask any questions, ill get back to you ASAP.

Clicks twice when plugged in? Likely the PSU is dead.
Test the PSU.

If the PSU tests out OK, then try a replacement power button board.

Powermac G5 wont boot. Please help!!!

my PowerMac G5 wont boot, power suply or graphics card? When i press the power button is the chime and then after a while (fem minutes) the fans start revving up, all with a black screen........

See if it will come up into Open Firmware and let you do an NVRAM reset.
Hold the cmd-option-O-F key combination when powering. If the screen actually comes up, you should see a light background with black letters. To do the resed, enter the following three commands.
reset-nvram <enter>
set-defaults <enter>
reset-all <enter>
I don't have a lot of hope, in one sense, but it you get the OF terminal screen, then that says at least that at its basic guts, the machine is sort of working, and we can go from there. And, if it does make it into OF, the resets might actually clear things up.

New board wont boot, help please

Hi.
I have just bought MSI K9A2 Platinum with a quad core phenom 9950 black edition cpu. and ati 4850 pcs 1GB gddr3 pci-e 2x 2BG corsair ram.
I built the rig but when i push the power button everything seems to work, fans spin, cpu warms up graphics card warms up (the heatsinks) but the monitor says no signal.
Sometimes the monitor goes into standby and other times it stays on but with no picture.
Has anyone come across this problem and does anyone have any ideas why this is happening?
I have cleared bios, unplugged all usb pins etc. tried with 1 mem stick and 2 , and un plugged hard drives.
Many thanks for any help.

Thanks for all the suggestions.
The board is now booting. one of the memory sticks is dead, wont boot with it in, take it out and its fine
The problem i am having now is i cannot create an array.
in the create an array options, option 1,2,3 don't do anything but 4 does.
I managed to format the drive and the OS is loading as i type, but when pc boots it says no array created, so if I am getting the Sata speed right, if an array isn't created then it wont be running at full speed.
Ive tried changing bios setting in sata control bit... IDE, Raid and a....... cannot remember other options, but none of them work.
OS is now up and running, everything seems to be working. just strange that it wont allow me to make an array.
Any ideas thanks

Powermac G5 wont boot/no boot sound/no video just flashing led

Ok, I think I have a serious problem, the problem came up when I removed RAM, and befor that computer worked just fine (i have dual powermac G5 2GHz).
And after that to resolve that issue I tried everything:
- reset PRAM;
- reset SMU;
- unpluging everything and holding down power button while connection power cord;
- removing video card and powering up;
- moving RAM around and powering;
And nothing helped. Every time I power up the computer there is no chimne, no video, just falshing led!
So if anyone knows of any else options PLEAS HELP, I came to dead end.
Thanks

I've tried it with cabels unhooked and with new battery, and nothing, same problem no boot sound just flashing light.
After that I also measured the power connector (because earlier I bought a book from PeachPit - Desktop and Portable System, which all I can say is not worth the money, but there is little chapter talking about a power supply verification) and the voltage is correct (+5V), so the power supply is OK.
All I can say is that this was my first powermac and i bought it from second hand so there is no warranty, and in Slovenia there aren't any service technician, the nearest is in Austria. I'm very, very, ...... disappointed about the quality of powermac's (although I bought it from second hand it cost me a lot of money, which I don't have).
I will not buy a new logic board to check if it's solution for the problem, and I'm very enthusiastic about computers, i'll probably leave and eventually sell it for pennies (and lose 1000EUR's, bull **).
The end point is that anyone who is buying a powermac g5 with no warranty, earlier model don't do it!! I don't know about MacPro's.

24" iMac - Wont boot from HD or disc... Help!

Hi guys,
Just been working on iMac, forget the exact spec but it's a 24" Intel 2.something Core 2 Duo or whatever it is, 4gb DDR2 RAM, gotta be about 2 years old to the day and after my last 2 Macs have lasted forever, never developing a fault, I didn't take out Applecare... Perhaps I had a bit too much faith...
As I say, just working away and all of a sudden, upon putting a video in Quicktime to full screen, the whole image has kinda of condensed itself into the top 20% of the screen and started slightly flickering the image. I've tried quitting some of the programmes, but neither the mouse nor leyboard have been responding so I've just had to turn the computer off.
I've gone to turn it back on, and after about 30 seconds, it's got as far as the grey screen but then the little spinning progress indicator pauses and it does nothing else.
I've reset the PRAM and that made it take longer before it froze but ultimately did nothing.
I've now tried getting it to boot from the Snow Leopard disc but this does the something, until after about 3 - 5 minutes, the screen goes all pshychedlic, like looking at an old school TV really close...
So looking for any suggestions on other things to try before I have to take to my local store... Any hazard a guess at what may be up with it?
I've got a back up the whole computer but I don't think this is a software problem, I'm assuming it's going to be a hardware one?
Any help at all would be much appreciated!

Ok, tried Safe Mode and that wont boot either. Saw a little progress bar on the grey screen though which made a change, but ultimately, it crashed once that had disappeared.
I've just noticed that at the point when the progress wheel stops spinning, a pattern of dead pixels appears across the screen that aren't there when the progress wheel is spinning.
The more I talk to people about this, the more graphics card seems to come back as the likely culprit, based on the fact that:
- it started by me putting a video to full screen
- the fact the display went weird when it first happened and also it plays up after it crashes with the psychedelic colours
- it wont boot from HD, disc or now in safe mode either, however it does run AHT fine.
- I've hoovered out the vents on the iMac and somehow it seems slower than it was before (bit odd)
- the dead pixel thing mentioned above
So now thinking it may be time to get a new graphics card?
Reckon this is likely, even though the AHT hasn't picked up any problems? As mentioned earlier, I'm not too concerned about it would seem it doesn't particularly test the graphics card too much, so all just seems to point towards it.
Anything else that I could do to single this out as the likely culprit?
Guess this is a chance to upgrade!

HP DV4-1155SE Black Screen and Wont Boot. Please Help!

Hello all I am working on an Hp DV4-1155SE. I have tested the memory modules, the hard drive and everything else that I can take out of the computer easily. Everything works but!, The laptop will not boot into the bios or anything else. Black screen, wont boot and i have the bios file that HP supplies on the support page of the site. I have looked at the instructions that a few people have posted about re flashing the bios and that does not seem to help me at all with this AMD processor. If anyone can please offer any help at all this would be greatly appreciated.
Thank you!

I will search on int 19h....thanks.
My problem started before the bios-screen.
This is what I tried this evening:
- Disconnected all non-essential devices...no effect.
- Cleared the CMOS...system booted to OS! Screens still garbled!
- Put in an older graphics-card...No artifacts!
- Put my MSI NX6600GT (AGP) back in...screen grabled while booting. Once in OS everything
looks fine at first. Later I noticed some odd random pixels. Playing movies is working fine.
Playing 3D games results in all kinds of strange looking artifacts.
- Installed the latest NVidia- drivers...no effect.
Is my problem still MOBO related or Graphics Adapter?
Any further advice?
Thanks!

My macbook wont boot up :-( HELP!!!!

Hi
HELP!!! My macbook wont boot up.
I was deleting some files off my system last night, Id put them in the trash and deleted them (there was quite alot!!) and the screen gradually went black and told me i needed to restart my computer by holding down the power key.
I tried doingt this but it wouldn't restart.
I left it a while and tried powering up, it seems to turn over once but the chimes dont kick in and nothing happens, the little light (is it the sleep light?) does come on but nothing else.
I really really hope someone can help!

Since you are still using Panther, try booting from your System Install DVD. Try running the +repair disk+ & repair permission options.
See Article http://docs.info.apple.com/article.html?artnum=301287 My computer stops responding during startup
If you have AppleCare, suggest that you contact them.

USB drive with install image is showing in Startup Manager on a Mac Pro, but wont boot. Showing circle with cross strip, and shut down automatically. USB device are made and work on two different MacBook Pro, but used on Mac Pro. Any help?

OS X installers have always been fairly specific, hardware-wise. I haven't read anything reflecting that situation with the Recovery HD, so it may be that the Recovery HD created for the MacBook Pro does not have the necessary drivers for the Mac Pro. Obviously, nothing definitive here, but a possibility.

My Windows 8 wont boot up help me!

Hi kinghamster678,
Can we get into the recovey mode ?Have you got a installation media or a recovery disk ?
Resettting the machine is the last option and we will lose all the data.We can try to boot from the installation media or a recovery disk.Then we can choose the recovery mode to have a repair.
"Startup Repair " ,"System Restore".

T60 wont boot ~ I NEED HELP ~

H'ok.. So I was going to try to fix my friends T60 but I'm worried this is kinda over my head..
She came to me and said the OS was currupt and asked me to install a new os onto her laptop..
I was only able to install anything when the built in Wireless card was disabled..
Whenever you enable the wireless card, windows wont boot (all versions) nor will Windows installer boot..
Linux will boot though with the wireless card enabled.. but wont see a wireless network.
I've checked the hard drive and the ram.. both are ok.
I tried swapping the wireless card, but that didn't fix the problem..
Could it be the motherboard?
I need help! PLEASE WILL SOMEONE HELP!
