Recently active topics in Apple about iMac

I now have 16 vertical lines on my iMac Core 2 Duo screen. It first appeared after my 1 year warrantee expired. The keeps appearing everyday now. Then I guess it will soon go dead after all. And I don't have an Apple Care at all. My iMac serial is W864XXXXXXXX. It's a late 2006 model. I am wondering if Apple will be responsible for this faulty as it happens to majority of iMac around the globe.

I just bought a brand new iMac today as a gift for my mother. I was trying to set it up and get everything working before introducing it to her, but ran into a problem I can't figure out how to fix. When I power it up, it either repeatedly powers up and then shuts back off, or it powers up, shows the Apple logo, then drops to a black screen. In either mode, it is unresponsive. I have tried all the suggestions in the instruction manual for resetting it and interrupting this freezing and powering cycle, but nothing works. I have seen on another thread that this is possibly a problem with Leopard and Apple has some patches to fix it. The problem is, I can't even get the machine operating to the point where I can get to the Web to download those patches. Any suggestions? I tried calling Tech Support, but it was after hours. I'm hoping they offer Saturday help.

How can I solve this problem?

Here's a newbie question.
When i say not now to downloads for upgrades to my system, where do they go and how to I retrieve them?

Over the past few years my imac has picked up many scratches on the screen from my removing dust, insects whatever from the screen. is there any way to remove these scratches?

Keeps adding 12 GB per day. My ext. drive now full.

First I purchased a macbook. It arrived covered in scratches. Apple tells me to drive 200 miles to an Apple store to replace it. Next I buy a 24" iMac. It arrives with dust trapped behind the screen. Apple tells me to drive 200 miles to an Apple store to replace it. Last week I buy a 20" iMac, it arrives with a tear in the aluminum, leaving a dangerous sharp jagged edge. Apple first tells me sure, they'll replace it for a $150.00 restocking fee. I complain, hey, this is your fault, and they relent and agree to pick it up and send me a new one. Appriox. $5000 in 3 macs, all have cosmetic defects, 2 200 mile drives, and not so much as a "we're sorry" much less any compensation from Apple.

I've got an old iMac at home, one of those crazy half-sphere things with the screen on a swivel arm that they had before the first pizza-box ones. The fan noise has become progressively louder over the past few months such that it makes a constant whine. Any ideas?

When I let my iMac sit for a while, it seems to go into a frozen state. All I see is the outline of my white mouse pointer on a black screen. I need to hold down the power button to do a hard reboot.

Does anyone know why this might be happening? It seemed to start after I upgraded from Tiger to Leopard.

The squares are purplish-blue and yellow, they're about 10x10 pixels, and usually start at a particular place (left side, near the bottom) and then spread the longer I use the computer.

They'll go away for a bit If move a window over them or if I bring up Dashboard, but they'll reappear in a few seconds.
