9300 Wont boot. Power comes on but no boot

So I got home from thanksgiving with family to see my computer was turned off. I hit the power button, and all the fans came on as normal, but no picture. Thought maybe it was just a monitor issue, I did a hard reset, (power button hold) and then restarted, It got to the boot screen, then shut off again. I pushed the power again, and still, fans came on, lights came on, but monitors dont come on.
Basicilly, what it does now is, hit the power button, fans come on, DVD drive opens/closes/spins, but nothing else, power button does not light, and power button does not react to hard reset (long press)
Things I have tried:
Removed RAM and treid to start, no change, no beeps
Removed Video Card and tried to start, no change, no beeps
Removed Battery
Switched jumper
30second power button hold
Plugged strait into wall (no Surge protector in between)
It was plugged into a surge protector when it failed, nothing else in the surge protector failed (other computer, monitor, modem, etc)
I am no computer expert, I know just enough to get myself in trouble, and most of the things I have tried is from other forums ideas.
Please help!
Thank you

Please identify your desktop PC with the p/n (product name/number).
Once you identify your PC I will link to a service & maintence guide and provide an image that shows where and how to clear the CMOS. When BIOS ROM file has issues it is often the case that clearing the CMOS brings the PC back to life.
You said "Switched jumper". What exactly are you referring to?
If you meant cleared CMOS, did you remove the CMOS battery ( quarter sized and marked CR2032) when you did it?
Kind regards,

Equium M40X-189 wont start up - Power comes on but blank screen

When powering on Laptop the power light comes on and the power supply fan comes on but nothing to the screen.
Then shuts down sometimes or blue power light stays on, then eventually turns off.
So frustrating, have no money for new one for daughter or to pay for an expensive repair, praying its a easy fix (but deep down no this will not be case).
Any help will be really appreciated.

Try reseating the Memory (RAM). Or if you recently installed more RAM, remove the extra module

Hi,
Troubleshooting a start up script can be difficult. There are some third party programs that also keep logs of start up programs, however for Firefox this may be different.
Is Firefox a startup program? [http://www.winxptutor.com/msinfo32.htm]
Its also possible to check the Web developer tools for any scripts in a page: [https://developer.mozilla.org/en-US/docs/Tools/Debugger]
In the control panel there is also Administrative tools to view event logs, but this may be something a local technician can walk you through.

Dm4 wont boot- hard disk error but passes hard disk test

My dm4 laptop froze yesterday and I was forced to restart it- it is 3 years old but I have had no issues with it. When trying to reboot it will not start and if I run windows repair it comes up with the failed 2 hdd error. I thought it was a hard drive failure as I originally got a 305 error code when running the hard drive test. Upon opening system diagnostics I ran the hard disk test and it passed no problem. However if I run any of the other tests- start up, run in, or system tune up, I get the error Hard Disk 1. I tried the hard disk test again and it passes. Ive run Avg virus scan and found no threats. I have no idea what is going on- I did a BIOS rollback and the computer still wont boot up. What is happening and can I recover my data?

With the intermittent errors,it sounds like the hard drive is failing and will need to be replaced. A retail laptop SATA hard drive can be used. Just be sure to get one of at least equal capacity as the original in order to use Recovery Discs. It can be larger, but not smaller capacity.For instance if you have a 500GB hdd you could use a 750GB hdd but not a 320GB hdd.
As for whether it is possible to recover your files it depends on how much life is left in the hard drive.Many times you can remove it, attach it to a USB Adapter or install in a USB Enclosure to plug into working machine via usb port and copy files over to the hard drive of host machine.
If you need more help selecting/replacing the hdd post back with full Model & Product Number as listed on the Service Tag attached to bottom of laptop.

I reinstalled osx 10.8.2 from recovery disk, now verify disk says my hard drive is there but wont boot into it regardless which partition i select to boot into , everytime it boots me into the recovery, i need help!

Mb pro running like garbage with 10.8.2 tried a reinstall of osx from recovery utility now the utility says my hard drive is ok but wont boot into it keeps booting me back into recovery tried restart option to select disk tried using the select startup disk from recovery, gives a message asking if i really want to boot to it and in that message is the only rime it shows a question mark on the drive dont know what to do cant find similar issue

Your rushing and not making much sense.
Your machine was running like garbage, so you tried to reinstall 10.8---did you do this or not?
Disk Utility says your drive is ok, that's good.
But when you boot it keeps booting Recovery HD, so perhaps the firmware has made a mistake, it can forget.
You held the option key down to boot into Startup Manager, why didn't you select OS X for the boot volume?
When you get into OS X you change the Startup Disk in System Preferences, that should take care of the Flashing Question mark issue.
attemtping to ireinstall osx from recovery partition bar is full on install screen, but im now at -6hours remaining
So now your reinstalling OS X like you set out to do before, it does take some time as it has to download from Apple's servers.
If your Internet connection is slow and/or Wifi is slow then it will take awhile.
So you should have the Flashing Question Mark and Reinstall Only OS X covered.
You should be able to boot the machine, but your performance issues may be something else and still remain.
Why is my computer slow?

My Macbook wont Boot, Power Light just lights up

I am having a HUGE Problem with my macbook pro. (Early 2011). I already brought this to the mac center but they could not find anything wrong with it. They said that the whole time it was with them their technicians did not find anything wrong with it.
The problem is that it wont boot up. The last time i was able to use my macbook pro (I am using it right now since it booted up) was 2 weeks ago. Today i tried my luck since i really needed to check my files and luckily it did boot up. but before this it would take an hour for it to boot up. After presing the on button the power light will turn on and after a few minutes a whirring sound will be heard. I will then turn off the Mac and turn it on again and the booting up sound will be heard. but last 2 weeks it was just whirring sound and after i turned it off and turned it on it wont boot up anymore until now.
I am really stumped as to what the problem of my Macbook is. Any help would be really appreciated.

Go through the steps - one by one - that ds store outlines in his user tip, Step by step to fix your Mac.
Good luck,

Power Mac G5 wont boot past the Apple Logo

Mac: Power Mac G5 2.7Ghz DP w/ 4gb RAM (2x1gb, 4x512mb), Leopard
Last week, I formated this computer and reinstalled OS X 10.5. I updated everything, reinstalled all my applications and replaced my documents. Everything was good for a couple days. I have and HP 1350 all-in-one printer (which HP no long has mac support for that model, so I can only use the scanner as a photocopier, but that's not the issue, it prints fine and I have printed files since the formatting) The printer is connect via USB to my Power Mac and then shared on my home network, wirelessly, with 2 other MacBooks and a 27" iMac. My roommate was trying to print something from his MacBook. In the printer queue on the MacBook, the file would say it was printing, but nothing would actually printer. When I went to the printer settings on the Power Mac, the dialog box said the printer was "in use." I reset the printer, nothing happened. I restarted the Power Mac, properly, and now the computer wont boot past the Apple logo. The spinning gear appears and spins for a minute or 2 and then it will just reboot on its own. It will just keep doing this in a continuous loop.
I've tried to boot into safe mode (holding shift) but it still does the same thing.
I manage to get the CD drive open by booting into open Firmware. I restarted the computer and was able to boot from the Leopard disc. I ran disk utility, and repaired the drive and the permission but everything was ok.
I've unplugged any USB device connect but to no avail.
I really don't want to reinstall Leopard again. it took almost 8 hours to install all the applications (such as Logic, Komplete 5, etc) and I had not setup time machine. There are some document files that I would prefer not to loose, but could deal with the loss.
any suggestions?

Ok, so I reinstalled Leopard, all my documents were in the "Previous Systems" folder, and the applications where present. I went to Software Updates to download all the need updates, which included 10.5.8, itunes, security fixes, etc. It notified my that I would have to restart. I click ok, everything was logged out and the updates started installing. As the computer restarted itself after the updates, i had the same issue again, where it would go to the Apple logo and then restart itself. The second time around, it just froze and the warning "You need to restart your computer" with the power logo in the background came up. So I manually restarted my computer and everything logged in correctly. I restarted it a couple time to see if I could duplicate the errors but everything keeps working properly. Now I'm kind of scare to restart my computer.
Any suggestions as to why this would be happening? Is this most likely a software issue or a hardware issue? This never happened before I formatted last week. The last time I formatted the computer prior to that was less than a year ago.

I have a PowerBook 145B but something is wrong with the systemfolder so it wont boot. I've downloaded System 7.0.1 from Apple and put it on Floppys with my Macintosh Classic. The PowerBook boots from the floppy, after a minute its just white. What to do?

I have a PowerBook 145B but something is wrong with the systemfolder so it wont boot. I've downloaded System 7.0.1 from Apple and put it on Floppys with my Macintosh Classic. The PowerBook boots from the floppy but after a minute it just comes up a window thats completely white.
I've tried a lot of things, but my Macintosh classic (with original floppys) runs 7.0.0. And the PowerBook needs atleast 7.0.1 and did run 7.1.0 as original OS.
How do I fix this?

Because your PowerBook 145B shipped with OS 7.1, it can't run an earlier version of the Mac OS, such as 7.0.1. Unfortunately, Apple never made OS 7.1 available for download. You can run OS 7.5.1, 7.5.3, and 7.5.5 on your PowerBook, but I'd recommend doing so with the maximum amount of supported memory - 8 MBs. The 19-part download of OS 7.5.3 is segmented, so that each one will fit on a 1.44 MB floppy disk. The problem is that the 19-diskette set isn't an installer set as such, having no bootable disk. It's solely intended to be used to transfer the individual segments to the resident hard drive in the computer. Once that's done, double-clicking the first .smi segment creates the OS 7.5.3 installer disk image on the desktop, which you drag onto the hard drive icon. This produces a folder with the OS 7.5.3 installer in it. I've done this before with an old Mac LC and it works. You can also download the 3-diskette OS 7.5.5 Update and run that. These downloads can be found on the same page where you found the OS 7.0.1 download: Older Software Downloads.

Try to boot in Safe mode, see if you are able: Hold down shift and then power on. For wireless keyboards, hold down shift after the chime.

Wont boot but fan runs

Laptop is a Satellite L655-S5076. My daughter turned her laptop on, the fan starts running slow then speeds up as if to boot but it just stays running fast. The LED for the power is lit but not the led for the harddrive. I powered it down holding the power button. I listened and watched when I powered up and noticed the led for the harddrive blinks on then off quick. You can here the HDD start to spin but stops just as quick as the led light. I thought the HDD was bad so I ordered another Toshiba exact part and it does the same thing. A different sight mentioned about the CMOS battery so I pulled and checked it. The battery read 3V so it was good. I reseated every hook-up and card that was removeable. It does the same thing with battery or wall power. The disc drive opens so I tried putting my Windows 7 disc in and it did nothing. Is it the motherboard and if so is it cheaper to buy another Laptop? This one was only $542 on sale Dec 2010.

Tried reseating the cards but it still does the exact same thing. Fan initially comes on at low speed the switches to high speed but no response. No Toshiba logo or anything. Good news though. My wife thought we had got a warranty plan when we bought it so I looked through all my papers and sure enough we had a 3 year warranty plan we paid extra for during the purchase. It is good until Dec 2013. I called and they are going to send it to a company that fixes PC's called Teleplan. If it can be fixed at a reasonable cost, they will repair it and ship it back. If it cost more than the laptop is worth they will reimburse the full purchase price including tax for the lap top. This is the first warranty I have used before it expired. So, Thanks for your help with ideas on fixing the laptop.

Okay, try this:
- connect all case wiring for front-panel stuff to the mainboard or short the two pins for Power-On on the mainboard's pin header with a screwdriver.
If that does not work:
- take the board out of the case to test it on a non-conducting surface in barebone configuration (CPU, video card, all power connectors, one stick of RAM) and repeat the step above
If that does not change anything:
- test with different PSU
Case closed, i put the motherboard outside the case and worked like a charm, seems like a bad conduct between the motherboard and the case, thanks for all the answers guys, it was the only thing i didnt examined and thankfully it was it and not some DOA board. Thanks again.

I have tried with a wired USB keyboard and mouse using a single screen. Powered up with option pressed. No change.

Run the Apple hardware test to see what it tells you. Run the extended test when prompted, which can take awhile.

My Iphone 4 screen just went black and it wont come on but it vibrates on ringer. Ps: The home button doesn't work. What do I do!?

If it never worked after the screen replacement then it would appear that you have a hardware problem either caused by the repair or the problem that lead to the screen replacement.
