Wireless connectivity with iMac G4 flat panel

Hey everybody,
We are thinking about buying an airport card for our imac G4 flat panel. We live in Ireland and are in the process of switching from a satellite dish-based Internet provider (connected via ethernet cable from the roof through the wall to the iMac) to our cable TV providers for a less expensive connection. The cable modem will be up in the TV room (the only cable CATV point that works), where we will attach a wireless router that will allow Internet access to the iMac downstairs and the iBook anywhere else in the house. Our cable providers offer 1, 2, 3 and 6 MB download speed packages. Here are the questions:
1) Is the "Apple Part No. M7600LL/E" available on macwireless.com the right one for our flat panel iMac G4 from 2003?
2) Is there any advantage to the airport card versus using a bridge? If so, which bridge is appropriate and easy to configure?
3) Which wireless router is recommendable to link with the cable modem upstairs?
4) Will the connection be strong enough between the router and the airport card or bridge to provide full speed and, possibly, VoIP (saving dough to one day be able to upgrade to a 20-inch iMac! LOL)? The distance is about 8 meters.
5) If we later upgrade to a new iMac and give our son the flat panel will everything still plug and play?
6) Which download speed package do we need to make everything run smoothly?
7) Is it really feasible for a "layperson" to install the card themselves?
Thanks again for your help!

Forgot to say in my other post. There's no need to buy at that price ($199) and pay for shipping - there are plenty of UK/IE options for buying.
There are also alternatives like Ethernet over Mains electricity (14 or 85Mbps) which may be a better option than original Airport.

I need help with imac g4 flat panel download of leopard it tells me it cannot load on the system.

i bought a refurbished imac g4 flat panel. it is supposed to have an os but it only comes up with a question mark. I put leopard in and it tells me it cannot load on this compuert. system is 800mhz and 60g hd and 768ram. i have tried to do a fix through the utility and it says it does not exit and kicks me out. ANY HELP IS A PLUS.

Try holding down the option key then power on. This brings up the startup manager. Click on your hd. Click on right arrow key.
Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime. Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:
reset-nvram
set-defaults
reset-all
"The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."
http://support.apple.com/kb/TS1812?viewlocale=en_US
You have got get in open firmware to hack the mhz to be higher for the install. That is change what the machine reports as the mhz to be a higher number. Details:

Zyxel pk500z router/wireless modem loses wireless connectivity with imac

My iMac loses wireless connectivity with wirelss internet from my Qwest ZyXel PK5000Z modem/router intermittently. Have to constantly reboot the router to allow my Imac and other Mac notebooks nto reconnect to wireless internet connection.

Suggest that you take one or more of Mac laptops down to the coffee place and connect there to check your performance. If you get a good connection there....as I suspect you will...you know the Macs are functioning correctly.
If the Macs perform well at the coffee place, you need to contact the ZyXel support folks for ideas on why the PK5000Z device is requiring constant restarts.
As you might imagine....on an Apple support forum, we are not going to be able to provide much help with a ZyXel product.

Unable to set wireless connection with imac and Canon MX860 printer ...

I recently converted to a Mac and bought a Mac Book, iMac, Airport Extreme, and a Canon MX860 printer. i have installed the canon software numerous times on my iMac to set up the wireless connection. yes, the airport extreme recognizes the printer and i am able to connect to my private and guest networks. the signal strength is good. It's the next part that I'm always stuck at. The Printer settings does not display when i choose More Printers and select Canon IJ Network. I called Apple support and we tried changing my network settings to an unsecured network and it still has the same issue. It was recommended this may be Canon driver issue and advised me to contact Canon. I reset the Airport, changed my network name and password .. i think i tried everything and it still does not work. What was I thinking when i said i wanted to convert to Mac? I can't move forward and connect my macbook or pc yet until I successfully connect the imac. Yes, i installed the latest canon IJ Network tool. of course the USB connection is fine but that defeats the whole purpose if why i bought this printer. please advise how to fix. this is getting very frustrating.

Some help at http://store.apple.com/us/product/TV352LL/A perhaps in the comments.
And maybe at http://www.amazon.com/Canon-PIXMA-MX860-Wireless-Printer/product-reviews/B001R4C 5BK in the comments.
"I ran into the same network installation issue that I've seen in other Canon printers. Canon's network setup forces you to connect by USB cable first. Only after you tell the program that you want to use the computer over the network can you remove the USB cable, move the printer if needed, and if you're using a wired connection, reconnect a network cable. The process isn't particularly difficult, but it's more cumbersome than what other printers let you do, which is simply put the printer where you want it, plug in an Ethernet cable, and install the software." source = http://shop.pcmag.com/shop/product/pcmag/84634068.aspx?SB=6&OB=1
"MAC wireless network printer setup requires turning off firewall, and works fine if you leave firewall off (not recommended). If you set firewall at "essential connections only," wireless networked MX860 won't work. You must add MP navigator and solution apps to your firewall enabled list. Then it worked fine on the admin account, but still won't work on users account which required additional permission settings and selections. After 2 hours it worked fine, but I would've expected better instruction manual for MAC." source = http://cnet.nytimes.com/multifunction-devices/canon-pixma-mx860/4852-3181_7-3352 9769.html
"The only trouble that I have had with this machine is setting up the wireless network. The manual instructions are impossible for me to understand and I ended up having to call for assistance. Which easily solved the problem. And again when I had to reconfigure my network settings it was impossible to follow the logarithm of instructions in the manual. Again I needed to call for assistance. If I need help after the year manufacture's warranty I will be charged for these calls." source = http://www.zimbio.com/InkjetPrinter+Reviews/articles/1932/Canon+PIXMA+MX860+Wireless+One+PhotoPrinter
Even Windows people have trouble:

"I'm with you. I have my mx860 connected usb to my pc with the printer being shared but my wireless laptop can't find it no matter what I try."
And, unhappy Vista person:
"I had high hopes for this printer - it seemed to have it all. But the wireless feature never worked, it only worked on my gigabit network for about two weeks (only THREE print jobs including the test print), and never observed it to work via USB - Vista (x64 Ultimate) would throw an error saying it could not attach the device."

Trouble w/ wireless connection with iMac G3

I just got an iMac G3 (grape). Its running OS 9.2. I read on these discussions that the best way to connect it to the internet is with the Linksys WET54 ethernet adaptor which I got today. I have a Belkin router with a cable modem on my PC. I have another PC with a USB adaptor. Those all work fine. My problem is after hooking up this linksys adaptor it won't allow me to access the internet on this Mac computer. Anyone have any ideas? I thought all I had to do was connect it all via ethernet, no drivers to install, blah blah blah. And no I never did configure a home network or anything since the USB adaptor just picks up the router signal and I really don't need file sharing. Doesn't this adaptor also just pick up the router's signal or do I need to do something else?

Ok...I already did all that before I ever even posted this question.
Sorry, I couldn't find a reference to that in any of your other posts.
I read another post about the mac changing the IP address on its own and their solution was to trash the TCP/IP file from the preference folder, reboot, then re-do the settings in the TCP/IP and then they got it to work. I don't understand how to do that. If I trash the file, first of all how do you trash it and secondly how do you get back into it once it has been trashed?
Find the TCP/IP preference file in the Preferences folder inside the "System Folder". You can trash this. The file will immediately be created with default values when you reboot or access the TCP/IP control panel.
I was confused by infastructure or ad hoc choice so i chose ad hoc.
That should be set to infrastructure.
When I open the TCP/IP again it keeps giving the IP address as 169.254.4.145 when I put it in as 192.168.2.2.
You should have the TCP/IP control panel set to DHCP. If it fails to communicate with the Belkin's DHCP server you will get an address that starts with 169.
mrtotes brings up a good point. If your Belkin has an access control list (MAC address filtering) enabled you will need to add the MAC address of the wireless interface of the WET11.

IMac G4 flat panel with slow mouse and ever-whirring fan

hi there -
my lovely iMac has treated me well for some time now, but gradually over the course of many months, it decided that it will not stop running it's fan, even when it seems cool it the touch and the room is cool. The noise is loud enough to drown out quiet music, and usually kicks in if the computer has been off overnight within about 15-20 minutes of startup, never to stop. i ave tried giving her space, moving the routers etc away, but alas...
also, my mac has become prone to freezing the mouse quite often, but unplugging the mouse and replugging it seems to always fix it for a bit, but only temporarily - like 3 minutes or so sometimes, sometimes it's fine for longer after unplugging but just slow to react. and while it never used to freeze up altogether, it now quite often does.
we have a good amount of programs and music, but i don't know enough about computers to know how much is too much. we always try to keep as little running as possible - i.e. just netscape, or netscape and itunes, or just itunes. here are my computer's stats:
iMac G4 flat panel, 700MHZ Power PC G4 768 MB SD RAM
i don't know if this is helpful, but:
capacity on hard drive:38.15 GB available: 2.87
any thoughts from you experts out there would be so very greatly appreciated. i love my little mac dearly, and don't want to see her bite the dust if all it would take is a little preemptive work! please help.
iMac g4 flatscreen Mac OS X (10.4.8)

My interpretation of the information you noted about the capacity of the
hard disk drive and the remaining free-space, is indicative of too-full a
hard disk drive so that could be the main problem. Instead of less than
10% capacity remaining unused, you need to have more like 20% free.
There also is a chance there could be bad sectors or some low-level
corruption on the hard disk drive, in part due to it being too full and
the drive is also using alot of space normally used as virtual memory
by the system, so these small remaining places not filled all the time
are being re-used and that could force the machine to cannabalize
other data stored on the hard disk drive while the OS is looking for
VM (virtual memory is automatically allotted and maintained by the
system, by using hard drive free space; all applications and utilities
on the computer use, need, and look for it.)
Other causes of kernel panics could be related to hardware or software.
Since the hard disk drive is extremely suspect, that is a place to start.
The use of an external FireWire hard disk drive to save some files to,
may be helpful; setting up a new external FW HDD may be hard since
your computer maybe too full to get and use a cloning utility (superdooper
or carbon copy cloner) but you may be able to save some items to CD
or DVD-R media; and then start moving the originals of your saved work
from the computer to the trash. A utility such as What Size can be handy
to see what files are huge, where they are (and note system files are not
the ones you need to toss; user generated ones are) and delete some.
If the hard drive has sufficient damage from over-writing data, it may
need to be replaced. If not, it may need to be totally erased and the
Disk Utility used to zero old data and reformat. This is where a working
copy (clone) on an external drive could be re-cloned back into a Mac
from an earlier capture of the healthy system, and save alot of time in
the restoration process; since a clone does not require all the installer
discs to get a full system back. It does require forethought and action
before a problem; and making backups of your system off the computer.
I make complete computer hard drive copies with a clone utility; but these
are not automatic. It is possible to set up a computer with an automatic
backup system to make ongoing clones of the complete internal drive.
The slowness of your system and peripherials is most likely the full
hard disk drive; and/or issues resulting from that. I suspect this area
is one requiring action and may be just a starting point to fix damages.

Hard Disk Upgrade - iMac 17" Flat Panel G4 1.0 GHz with USB 1.2

I’m considering upgrading the internal hard disk with the following:
[Western Digital Caviar SE16 WD5000AAKB 500GB 7200 RPM IDE Ultra ATA100 Hard Drive - OEM|http://www.newegg.com/Product/Product.aspx?Item=N82E16822136111]
I read that others have successfully installed 500GB IDE disks. I have a two related questions:
1. Do these larger disks cause any heat or power supply issues?
2. I've seen several take-apart instructions. It seems like there are subtle differences with the various Flat Panel models. Does anyone know which instructions apply specifically to my model (iMac 17" Flat Panel G4 1.0 GHz with USB 1.2)?
Any insight and/or experience on this topic would be greatly appreciated.

I have exactly the same question.
Thing is, having did a bit of research I read that USB 1.1 machines can't support anything more than 120GB?
http://www.macupgrades.co.uk/store/machine.php?name=imac-g4#int-hdd
"Compatible with the 1.25GHz model, and 1GHz iMacs with USB 2.0. It is not compatible with 1GHz iMacs without USB 2.0, or any slower models. Professional installation recommended."
http://www.macupgrades.co.uk/store/productinfo.php?productsid=71
"Be aware that many G4 PowerMacs have a 120GB capacity limit on the drives they can use, if you want to use a larger drive on these Macs we recommend adding a SATA controller card such as the Sonnet Tempo SATA PCI Card, and then using a SATA hard drive rather than an IDE one."
It wouldn't have to be this IBM model, in fact I like the sound of the Western Digital machines mentioned here, but I just wondered if anyone knew if the mac CAN support more than 120BG. I notice this company also state that it can't take more than 1GB RAM, but that's been proved wrong in other threads.
Thanks!

Printing on Wireless Network with iMac G4 EXTRA Page with jibberish.

Hello folks,
I hope to find an easy fix. In my wireless network environment there are 6 PCs and one iMac G4 Flat Panel (OSX 10.4.6) that share a wireless router, and 3 wireless print servers that have 4 different printers attached.
Everything works very well, except, for when the iMac prints to the Lexmark Optra S 1250 printer. The very first page printed (everytime) has one line of jiberish like this:
[%-12345X@PJL JOB @PJL LJOBINFO USERID = "username" HOSTID = "imac15.local"@JPL S
After this very first page prints, everything that follows is printed perfectly. How do I turn off whatever it is that causes this page to print? When I print to any of the other printers it doesn't occur. It does not occur when any of the PCs print to the Lexmark either.
I thank you all for your time and hope you can help.
iMac G4 Mac OS X (10.4.6) Belkin 54g router, Linksys WPS54GU2 printservers

The question here imho is does it have to be wireless?
If the router is close to the Macs surely Ethernet would resolve any issues and provide fast performance.
If the XP machine is reliable wirelessly leave it wireless, you can always connect that using Ethernet if you want to transfer larger files to / from the Macs. This will also give you some convenience.
If things must be wireless then it'll depend on how much you want to spend. Since you'll need a new fast a or g router (avoid pre-n now, wait for something confirmed to work well with Intel Mac and others). The G4 would need a Wireless Ethernet bridge to give a fast connection since USB 1.1 is just too slow or Ethernet again.
So it depends on you realy and the location of the computers. Nothing wrong with a mixed Ethernet / Wireless network easy enough I have one
Nothing mentioned on router site about incompatibility with Mac OS 10.4.8. Once the router is configured using the web interface or software supplied you'll need to config the computers accordingly.

Mac will no longer turn on - iMac G4 (Flat Panel)

I have an iMac G4 (Flat Panel) that will not turn on. I've tried to obvious things such as changing the power lead/fuse etc., but this hasn't solved it. If you hold the power button in you can hear a faint 'ticking' sound coming from inside the Mac, but it doesn't power up. I'm guessing something more serious has 'blown' inside, but I have no idea whether it's a lost cause, or something that could be easily fixed. Any ideas?

Hello Matt,
I have the same problem you describe. You may want to try what I did to bring the iMac back on. I just leave it alone for a day, with the power cord disconnected. Then I try my luck by connecting the power cord back and start up again. Some patience is needed here as I am successful only after half a dozen of retries. I also hold the power button until I see the lights on the mouse comes on.
Once ON everything works fine..software restart is not an issue either..just dont shut down..then u may have to to wait another day to try again..I was lucky four times and did this in the past week. ..can be frustrating but lucky i still have the G5 to use.
I dont have the proper solution to the problem and still trying to figure out what is the cause..I have reset the PMU (see apple support website on resetting the PMU) but the problem still remains. Another forum participant suggested to change the internal battery (an inexpensive exercise) but Apple website advice us not to do it and let them do it..but I will likely try to do it myself later.
For the time being, hope you can start up the machine like i did.

IMac G4 (Flat Panel) Hard Drive Replacement Cost

I have an 800 mHz iMac G4 (Flat Panel) that was originally purchased in approximately 2002 or 2003. The hard drive has died. I have three questions:
What is an approximate cost for a new hard drive?
Where can a hard drive for this computer be purchased?
What do I need for an OS installation disk? I no longer have the install disk that came with the computer. I believe it came with Panther, but had since been upgraded to Tiger.
Many thanks.

Finding the drive is the easy part. Any of the hard drives on this page:
http://eshop.macsales.com/search/3.5InternalIDE/ATA
will work. Your iMac uses IDE/ATA or PATA drives, not the later SATA drives. PATA drives are getting harder to find and the vendor I linked is one of the few who still carries them. Older iMac G4s may or may not recognize disks larger than 128GB. If yours doesn't, you'll have to partition any new drive so there is a Mac Extended HFS+ partition that's about 125GB and leave the rest unformatted. It's a hardware limitation common 8 years ago.
The next problem is that the iMAc is one of the most challenging Macs to take apart and service, and you have to go deep inside to get to the hard drive. You literally enter at your own risk. There is a significant chance of the computer not working afterward unless you can find someone who knows how. Apple does not work on these any more so you'll have to find a person or firm with Apple experience.
You are about to find out how expensive misplacing the system disks (CD or DVD) can be. To reinstall the OS, you need either the original gray disks that came with your computer or a full retail install disk set. The later for Tiger is no longer available from Apple and those copies on the market are going for up to US$250. That greatly exceeds the value of a G4 iMac on the used market. There is such demand for Tiger that the criminal element has sneaked in; I've seen blatantly illegal version of Tiger offered on auction sites. They are as expensive as the real deal and may not work.
It's remotely possible that you can call Apple and give your serial number and they can find a gray disk set that matches. However, the are out of those sets for computers made in 2004 so it's a long shot.
Your best bet may be to connect with a Mac User Group. They often have people who do pro bono service and may have system software as a reduced price compared to the price-gouging going on in the open market. This page can help you find a group near you:

Imac 15" flat panel

Question, is there any web sites that show "How to put a larger display on 15 older Imac G4 Flat Panel Imac?" The type that look like a half ball, with the display on a pole. I would like to put a larger 19" analog LCD display on this Imac, one you can purchase at Best Buy or whatever?
ibook g3 800, G5 imac, FTP imac, Pbook 15" Mac OS X (10.3.9)

You'll generally get quicker and more accurate responses if you ask in the iMac area. This forum is intended for older, pre-PowerMac G3, hardware.
Anyway, Your Mac officially only supports screen mirroring, not "extended desktop" mode. So all you'd get is a larger copy of the same image you'd see on the iMac's internal screen. If that's what you want, all you need is the Apple VGA Display Adapter and a VGA monitor (most will work).
If what you were hoping for is to run the external monitor separately from the iMac's screen, there is a utility here that claims to enable extended desktop on some iMacs and iBooks. I do not endorse such usage since some people have reported that the hack completely messed up their systems, though, so use the hack at your own risk. Note as well that if you have problems with the system due to this hack, Apple may well not honor the warranty (since the hack constitutes an unauthorized modification, prohibited in the Apple warranty). But it has reportedly worked well for a number of people.
Regards.

Upgrading the HD in a 700MHz iMac G4 Flat Panel

I want to upgrade my iMac to a bigger HD. I was told these older iMacs
can only read up to 160GB hard drive and it needs to be an IDE drive? Is this true?
What's the largest capacity I can go on an older iMac such as mine? Thanks.

Hey S'berry,
Unfortunately your 700 will only take up to a 128GB drive but according to:
http://www.everymac.com/systems/apple/imac/imac-g4-flat-panel-faq/imac-g4-how-to -upgrade-hard-drive-use-big-drives.html
"Officially, Apple says that Macs running MacOS X 10.2 or higher released after June 2002 can use "big drives" -- those larger than 128 GB -- which would exclude the original iMac G4/700 (Flat Panel) and G4/800 (Flat Panel) models. However, third-parties have discovered that all iMac G4 models will support big drives running MacOS X 10.2 or later. For earlier versions of the MacOS -- including MacOS 9 -- a third-party driver, such as those from Intech or GenThree are required to use hard drives larger than 128 GB."
You could talk to OWC about this:
http://www.macsales.com/
I remember not bothering w/ this and using a 128 GB boot drive and then using larger FireWire externals which were not subject to the restrictions.
This might have changed w/ improvements in that software solution so talk to OWC.
Also in answer to you question about wireless look at my last post here:
http://discussions.apple.com/thread.jspa?threadID=2365560&tstart=0
Your machine will take the original Airport card. Here's one on eBay:

Blue thin line on the lower left iMac G4 Flat Panel

Hi, since yesterday there is a blue thin line (0,039 inches (1 mm) thin; 35 inches (9 cm) long on the panel of my iMac G4 Flat Panel. It looks like drawing with a ruler, so straight and so fine.
The line is on the left lower corner in a vertical position. At first I thought these are dead pixels, but I checked this. No dead pixels. I have changed the desktop picture etc., but it`s all the same. I run the apple hardware-test cd - no problems found. Is there someone with any idea? Is it possible to have a damaged graphics- chip although the hardware-test is o.k.?
Does it make sense to open the iMac and look for dust and dirt on the motherboard?
Thank you for any help, Matse

Matse,Willkommen zu den

What happens if you change the
display resolution? (Apple Menu > System
Preferences... > Displays > Display tab >
Resolutions) If the line stays in exactly the same
place despite the resolution change this points to an
LCD rather than graphics card issue.
mrtotes
thank you Adam for that hint. The line stays exactly in the same place. That means it is an LCD issue? That´s your opinion? Do you have any idea if it is possible to repair it, or is the only possibility to change the panel?
Thank you, Matse

IMac G4 Flat Panel 1Ghz - 1 beep when turning it on.

I have an iMac G4 Flat Panel 1Ghz that beeps once when you turn it on. After doing some research, I learned the 1 beep could be no RAM or RAM problem. I replaced both the internal RAM and the easily accessible RAM with RAM from a reputable dealer that markets this RAM just for iMac G4s. I still get one beep after startup. I tried taking one stick out and all variations of using the old and new RAM with no difference. I did more research that maybe it was the power supply. By the way, originally this iMac was shocked through its Ethernet port with lightning. I since bought a new motherboard, new RAM as stated, and now also the power supply. After putting it all together, I still get one beep at startup. I have reset the PMU also. Also added a new battery. Looking forward to your suggestions.

There may be some indication of the beep's cause after some thorough
testing of the computer with some utility software; perhaps even the basic
Apple Hardware Test which would have accompanied the computer when
new could be helpful to some degree, if the machine were run in that, in a
long continuous loop to see if at some point, it may generate some codes.
However, the startup sequence itself is where such a hopeful bit of information
would more likely be generated; and this is the kicker, in that some of the info
at start-up is too early in the beginning of the run-cycle to be recorded or read.
But, you may find evidence of the issue in the Console error message reports
in that utility; and there are a few different sub-titles of places in Console to look.
Also, you may be able to find some error or crash messages, or other runtime
messages and glitches, in the System Profiler> Software> progression path.
There may be another source of the single-beep on startup tone. Not sure of
any other, though; since the Power-on self-test is generally what checks out
those computers on start-up. And the 'single beep' suggests there is a RAM
issue, as this Beep would replace the normal startup chime.
So, that early in the startup, and without a booted system, the error logs or
crash and failure reports would not be generated to be read later.
Is the computer you have really a 20" LCD and does it truly have a 1GHz
CPU? Or, does it have a 1.25GHz PPC processor, as it should? Did the
company you obtained the replacement logic board from, have anything
to say about the kinds of issues you've noted the computer displaying?
There may have been a limited duration warranty on the rebuilt board.
There have been a few of the old iMac G4 17" & 20" 1.25GHz models
generating an odd, single 'buzz' sound after the normal startup tone.
Is your's making a 'single beep' or a 'buzz' sometime after booting?
Do you have any other RAM chips of correct supported version to
replace one or both RAM slots, of reliable quality product? How was
the OS installed into the computer, or have you been unable to do so?
Once in a great while, new correct RAM could be bad on arrival. Rare.
{This is a lot like chasing gremlins or setting a trapline for gnomes.}
Maybe someone, such as the contributor alias 'spudnutty' may know of
some other factor in this matter that he has found, that may cause that.
Good luck & happy computing!

Can't start up past gray screen on iMac G4 flat panel

My iMac G4 flat panel is messed up right now and I'd appreciate any help I can get here.
This morning after I realized my internet wasn't working I tried a restart but the restart stalled around the part where it just shows your desktop picture and wouldn't fully shut down. I watched this for about ten minutes and then held down the power button on the back to shut down. When I tried starting back up, it would just get to the gray screen with the apple and spinning gear and stall out there. The gear keeps spinning but I can tell from listening that the computer is not doing anything, and it just stays like that for a long time. My OSX disks are in Toronto and I'm here in Kingston, but I was able to start up off my housemate's ibook start up disk and run disk utility. Disk Utility said there was no problems with the disk, I told it to repair anyways and it told me no repairs were needed. However, when I tried to restart off the hard drive, gray screen again.
I know there's been some similar threads here, but I haven't found much help from them. If anyone can give me some advice as to what is making my iMac stall out like this, I'd really appreciate it.

check out the screen I get when I hold command at startup, what does this mean? none of the keyboard buttons respond to this or the mouse, except the return key which brings me back to the grey screen hanging forever.
