L512 Wont Boot , Splash Screen then stuck blank screen and Fan in full throttle

I was using the laptop, then it went to suspend mode due normal timeout.
When it came back, the fan start to spin full throttle but it was functionating beside that, normally.
I restarted but then it never boot again.
This is the process where it gets stucked
Boot to Splash Screen, Beep, then a black screen and the fan start to spin at full speed.
(In the post in diagnostic mode, shows no error, pass the memory check, shows the info of the processor )
I tried this:
Retired Hard Disk,
Press 60 Seconds (Reset BIOS) - without battery and power cord
Press 10 times the power button an then 30 seconds -- without battery and power cord
Visually there is no damage in the usb ports, maybe i will need to disassembly to get a better view to check if there is a short somewhere.
With this symptoms , what should else i try. Could be a memory issue?
Thanks for any help you can provide me.

Thanks to the Mod!
It happens that if i wait for about 30 secs, then it will boot up, asking a proper boot media.
I was testing it and was workiing fine, except for the Fan working at full speed, Not suspending or shuting down or Hibernate. Only blinking power button led. So a rude disconnection /Battery Extraction needed to acomplish full shutdown.
But Now in the bios diagnostics splash shows
2201: Machine UUID is invalid
The bios shows only 0s in the uuid section.
i was looking for some imformation about this problem, and i found tah can be solved using some kind of floppy for servicing the laptop.
I ve already downloaded a copy, Havent tried yet, But plan to do some test. as soon i can get some spare time.
It appear tha some comand will let me regenerate the UUID, and with some luck, reflashing the bios will solve my problem.
I'll update as any new steps performed

Vertical stripes on boot up followed by a blank screen

MacBook Pro (15.4-inch: 2.4GHz (MA896LL/A) ) has vertical stripes on boot up followed by a blank screen.
Any help or suggestion on the cause greatly appreciated.
Thanks

It's likely that the boot drive is failing, or that there's some other hardware fault. Run the Apple Hardware Test.
Intel-based Macs: Using Apple Hardware Test
Even if the test is negative, you should make a "Genius" appointment at an Apple Store to have the machine tested more thoroughly.

I am having the same problem ever since I upgraded. Have received four emails from Apple support on the
issue and nothing has worked. Unloaded 10.5 and went back to 10.3 which worked fine but it would not allow
me to sync my Iphone with the ios 5 upgrade. Went back to 10.5 and sometimes get exactly what you do when
I try an access the store. It looks like something is clearly missing. Have done just about everything I have seen
on threads but nothing works. Really need help.

No, sounds like when you dropped it an cracked the screen it may have also damaged the logic board or the repair person damaged a cable.

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.

I had the same problem but looking at what everyone else said, I simpley slowly started to click on all the tabs in the app store, let them load completely, and then clicked back to the updates afterwards. It worked after a little while

TS1424 Downloaded rented movie but only 1/2 abl to play, then get blank screen

i rented movie a movie from iTunes. It took 10 hours to download due to connection speed at a hotel. afer downloading, everything looked ok. halfway into the movie it went to a blank screen with no response while in videos. I was eventually able to double click the home button, rewind, then stop the movie.
Now, how do I get the rest of the movie? i only have 24 hours to watch it before it disappears from my iPad.

I'd report the problem to the iTunes Store.
Log in to the Store. Click on "Account" in your Quick Links. When you're in your Account information screen, go down to Purchase History and click "See all".
Find the item that is not playing properly. If you can't see "Report a Problem" next to the item, click the "Report a problem" button. Now click the "Report a Problem" link next to the item.

Imac wont boot, Stays at a grey/green screen

I am trying to purchase an Imac G5 off of cragislist from someone that says it boots, doesnt chime and stays at a grey/green screen (not sure why its grey/green) Any thoughts about why it wont boot? Im hoping its not a capacitor issue.

Probably a failed logic board or perhaps capacitors. Could also be faulty RAM. I suggest passing on this "bargain"

HELP MY iBOOK G4 WONT BOOT I GET FOLDER WITH FINDER LOGO AND QUESTION MARK

HELP I have an iBook G4 and it frose so I shut it down by pressing power button and then it would kind of start up I would get a chime and a gray screen would come on for one second and the switch to another gray screen with a folder in the middle the has a finder logo that switches off between a question mark. But the funny thing is i started up yesterday and after four trys it worked then it froze again and i had to turnit off again it did the same thing i would just boot drom the leopard cds but they are missing. And its not like this was an on going problem it use to work fine.

Do you have the restore disks that came with the iBookG4? Without the Leopard disk, or the restore disks that came with your iBook, it's going to be difficult to trouble shoot.
Usually the "question mark folder" means your Mac can't find a System Folder to boot from. Make sure the iBook is shut down. Press the power button, insert the restore disk and hold down the C key all at the same time. Keep holding down the C key until you see the Apple logo. An Installer window will open. Select English, but DO NOT proceed with any installations. Instead, from the Menu Bar, click Utilities/Startup Disk. When the Startup Disk window opens, select MacintoshHD 10.x.x in the window and then click Restart. If the drive is functioning properly, it should boot back up from the internal disk.

Black Screen (no logo) then flashing white screen then a greyish screen and never comes on.

I left my iPod in my room for a few hours while it played my music. When I came back i assumed the battery so I charged it. Checked on it again and the ipod displayed a blank white screen. I looked up online how to reset/reboot it and tried it my self, but that didnt work. What happend next was that the ipod dispayed the black screen but no Apple logo. So i tried the reset/reboot process again then the screen flashed a white screen about 3 times then changed to a grey color. But cant access anything. What should I do.

If it is still charging, connect it to the adapter for 15min, then connect to your computer in recovery mode, explained here: iPhone and iPod touch: Unable to restore
