Computer won't POST on cold starts

When I turn on the computer after not having used it for over an hour or so, it won't post. Everything turns on, except the monitor. The only way I can turn off my system after it posts, and the monitor is still off, is by turning off the power supply. I found a way of turning it on when doing a cold start, but its really annoying to do. I do this by turning off the PSU, and unplug the monitor from my vid card, and then plug it back in. After doing this, system will turn on no problem. How do I solve this? I know monitor and vid card work good, since they work perfect in my other system.
Oh one more thing, after having a successful start, and having loaded Windows, my CD-RW is looping, the light stays on, until I open/close it, then it stops. Any suggestions?
Oh and I use K8N Neo-FSR.
Edit: PSU is an Antec TruePower 380. 18 amps on the +12v line.

Hi,
I've had lot's of trouble with my system. It didn't POST either. The problem you describe is not the same, but I see you are using the same video card as I do.
My problem was 'resolved' by upgrading the bios version 1.52
I've seen quite a lot of messages indicating that it could be the power supply, being too weak etc... Personally, I do not think it is. In my view it has something to do with timing, and bios 1.52 resolved it for me.
Good luck with it; this issue is a time consumer ...

Computer won't get past grey start up screen after install

Okay - I made a stupid mistake. I started the installation process - it was taking a very long time so I decided to quit and free up some more space before trying again. When I quit it wouldn't let me go back to my old version - I think I was on 10.3.9. So I installed 10.5 - and it said it installed successfully. I restarted and the computer won't get past the gray screen. I let it go for 30 minute the first time, 15 the second time, and about an hour the third time. Won't go any futher. Any ideas?
Thanks,
-Brad

same thing happened to me (you need to read all the posts as someone will have had the exact problem as you).
any way,
1. re-installl 10.5 from your leopard disk. (put disk in restart holding c key down etc). do not install OS just yet.
2. run disk utility (it does not hurt-click on options button)- repair both disk and permissions
3. run 10.5 installer (archive)
4. download 10.5.2 combo from apple (that is if you can easily find it!)
5. run that install
6 it will restart two or so times
7. total time is 20 mins or so. most of that is in repairs form #2.

MS-6351 motherboard, computer won't POST

Hello,
I need help reviving my faithful (or I guess not so faithful) MS-6215 book pc system. It has a MS-6351 motherboard in it, check out my sig for other details. This morning I when I woke up I noticed my screen was off, I shook the mouse around and banged on the keyboard but my comp wouldn't wake up. So I turned it off, turned it back on -- black screen, won't even show BIOS message. The 4 D-LEDS in the back show that the uppermost one (#4) is red and the rest are green. What does this mean? Nothing in the manual. I've ripped open my comp completely, booted with nothing but memory and keyboard and monitor cable attached, still the same result.
However, I did notice my power supply was was especially whiny when I opened the comp up. See signature. Could a faulty power supply generate these kinds of problems? Any advice or help would be appreciated. Thanks!

My Macbook won't get past the start up screen

Hey everyone
I have a Macbook that's about 3 years old. I did an software update yesterday and since doing it the computer won't get past the start up screen. There's just the Apple logo and the rolling ball thing. It's been stuck there for around 30mins and nothing changes. I'm not really sure what has happened but I was wondering if there is any way I can fix it.
Thanks for your time.
Bevan

Hey Lyssa
I don't have a back up but I'm not to worried about that as it's my traveling computer and I only use it for the web and some word processing.
I don't have the disks with me right now as I'm away from home. I'm not sure what I had updated, I think there was a lot because I hadn't don't it in a long time.
If I can start it in safe mode what should I do?
Thanks.

PC Won't Post: D-Bracket Shows 4 Red Leds= CPU Damaged?

Hello all. New to these forums. I recently upgraded to an EpoX 8RDA+ and am trying to setup my KT4 Ultra for my g/f. After connecting/installing everything the computer won't post. Nada. The D-Bracket 2 shows the four leds red which means "The Processor is damaged or not installed properlly." I tried an Athlon XP 1600+ and 2000+ an neither worked. is going on? I'm going to remove the mobo now and put it in the case that my 8RDA+ is in. Any suggestions in the meantime would be appreciated.
System Specs:
MSI KT4 Ultra
Athlon XP 1600+ w/ Thermalright SK6+
512MB Kingston HyperX
420Watt Codegen PSU

I have had problems like that a clople of times. Once the processor was dead on arrival and the other was when the fan was not enough for the processor.The system got stuck even before the screen appeared. In your case check if the fan is installed correctly.

Computer won't start if ipod is connected

My computer won't start when my ipod (nano) is connected. He stucks in the post screen of the motherboard. Before the pc will check what the boot drive is. So, changes in boot devices in bios won't work. What can be the problem?

mardymar: Windows may be seeing the iPod as a bootable disk....the following link talks about confusion as a network drive and could be cuaisng the same.

Did you change your BIOS boot order - I think you might try that if the above link fails to help.

Computer won't start & fails to wake from sleep

First post -- I have a 2009 HP Pavilion Elite w/Windows7. Good box & OS, never a problem until now. Started about a month ago w/the box not waking up from "sleep" -- no response (power light turned from amber to blue as usual but nothing else happens). Had to turn it off, but then won't come back on! After 10-15 minutes of repeated power-on button presses, it starts back up. Removing/reinserting the power cord during trys doesn't help. Occasionally it starts right up from sleep, but usually has this problem. Windows7 is up-to-date and no viruses or malware detected. HP or Microsoft diagnostics show no issues.
I opened the box to clean out dust -- also took off the CPU heatsink (really dusty) & cleaned it too. Fans rotate easily & aren't an issue.
So now I have "sleep mode" turned off, but occasionly the box has to be turned off & afraid it won't come back on. I've seen some of the HP videos & will try shorting the two start-up pegs on the MBoard, but the power-switch was hardly ever used & I seriously doubt that's the problem -- it wouldn't have anything to do w/the sleep-wakeup problem. Any suggestions?

Computer won't start from hard drive or CD, and won't perform system recovery.

I have an HP Pavilion g7-1314nr. Yesterday it froze and I held down the power button to turn it off. After turning it back on, it started a disk check. I turned it off during the disk check, and upon trying to boot it back up, it told me booting failed and to press CTRL-ALT-DELETE to try again. After multiple attempts, it stopped displaying this message. Under system diagnostics, I ran a boot test, and it failed. Attempting a system recovery brings up the start-up windows logo, and then a black screen with an enlarged cursor. This morning, I inserted a recovery disk and told it to boot from internal CD/DVD drive. Like system recovery, it brings the Windows logo, and then a black screen with an enlarged cursor. My computer is incapable of booting from either the hard drive or a CD. What do I do?

Hi @TeridaxXD001 ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion g7-1314nr Notebook and issues with Windows 7 and starting up. I recommend to restore the BIOS defaults. You could restore the BIOS with this document selecting the reloading the BIOS default settings which should resolve the fan issue.
Here is a link to computer won't start for Windows 7. There is a section on getting past the HP Logo screen.
If that does not help at the end of the document it shows you to do a hardware test.
Please note remove any and all USB devices before troubleshooting. Disconnect all non-essential devices
Hope this helps you out.
Thanks.

My computer won't start up after i tried to install updates

last night my computer told me there were 5 new updates available and i tried to install them, and my computer froze so i manually turned it off. now my computer won't start up. i get to the gray screen with the apple and the circular icon that swirls around which makes you think it's doing something but nothing happens. in the hopes that my computer was loading the updates, i let it run all night, and 8 hours later it was still doing the same thing. now my computer won't start at all, and i know there's power to it.
HELP!!!!!!!!!!!!!!!

chiae:
am i looking for the Leopard installer or the disc that came with my Powerbook all those years ago?
You are looking for the installer disk for the system which is currently installed on your computer, which is Leopard according to your profile.
Will doing these steps erase my hard drive?
No. Running Repair Disk will not in any way affect your data or any contents of your HDD. However, if there are serious directory issues your data might be jeopardized even without running Repair Disk.
Your question suggests that you may not have an up-to-date backup, if any backup at all. That is one of the most dangerous things you can do. I suggest that you take steps to secure your data even before you do much more. If you need ideas on how best to accomplish this, please post back and ask.
While you are waiting to locate your install disk, here is something you can do right now, and it will not in any way endanger the contents of your HDD:
• Shut down the computer.
• Locate the following keys: Command, Option, P, and R. You will need to hold these keys down simultaneously later.
• Turn on the computer.
• Press and hold the Command + Option + P + R keys immediately after the startup chime.
• Hold keys down until you hear the startup chime for the third time.
• Release the keys and immediately hold down Shift key to start up in Safe Mode.
• Log in and empty Trash.
• Restart normally and log in.
Please do post back with an update or with further questions or comments.
Good luck.

Hi my mid 2012 MacBook air simply refuses to start. My charger is working which is a good sign but even in safe mode my computer won't boot up! I recently installed a product called WhatSizeMac.

As said above I just installed what size Mac and now my computer won't start. As soon as I downloaded it my computer was a little glitch but regarded it as nothing. my computer was later really buggy so I decided to restart it. My computer now will not restart/turn on no matter if it is in safe mode or not. In safe mode it gets around a third of the way and then the progress bar disappeared then the gear remains for a second then the screen goes black then that is it. By the way I have OS X Maverick's .1 or.2, maybe .3 but I doubt it. PS if you can tell me a legit application that will declutter all this space I seemed to have used, yet have no idea HOW! Thanks.

If SMC and PRAM resets do not bring back life to your MBA, make an appointment at an Apple store genius bar for a FREE diagnosis.

Firefox is starting up on its own. I don't want it to because sometimes I don't need it, and when I go to shut down, computer won't let me because Firefox is running and I didn't know it. What to do?

I used to be in control of whether or not Firefox would load for any particular session on my computer. Now, probably after some update I got in the recent past, Firefox has a mind of its own. It opens every time I turn on my computer. There are times I don't want to use any browser, including Firefox. For example, sometimes I just want to look at my mail. Don't have time for anything else, but my computer won't let me shut it down. Why? Firefox sneaked in. So I have to find it and close it before I can shut down the computer.
HELP!!! How can I stop Firefox from automatically loading?
Thanks.

Welcome to Apple Support Communities
First, when you are going to turn off or restart your Mac, you will see a box called "Reopen windows when logging back in" in the shutdown or restart window. Untick this box and see if the App Store opens automatically in the next startup.
If it starts, open System Preferences > Users and Groups > Login Items, and see if the App Store shows up. If so, remove it from this list

Computer won't start up after 10.5.1 update

My leopard updates were a little rocky, but I got everything working eventually. However, after installing the 10.5.1 update yesterday, my computer no longer starts up properly. It hangs up for a VERY long time on the initial screen with the gray apple and little spinning symbol. Sometimes it eventually continues on to the logon screen, other times I get sick of waiting (literally 10 minutes) and do a hard reset. This only became a problem after the 10.5.1 update, and has been a problem every start up since then. I'm considering trying to roll back to 10.5.0 using my Time Machine backups, but thought I would check here first to see whether anyone has had similar problems (or even better, anyone has ideas about what's causing this and how to fix it). This is on my PowerMac G5 Dual 2ghz.
Thanks.

Zapping Pram didn't help, but probably wasn't a bad thing to do anyway. Another solution I've seen on another post is to start up while holding shift. This also didn't help. I have no external drives turned on, but I do have an 2nd internal drive. I've found a VERY STRANGE way to get it started: if I immediately open the CD/DVD tray while booting up, put the Leopard install disc in (probably any disc would work), and then wait till the computer gets stuck at the gray apple screen before closing the disc tray, it seems to continue starting up fine after closing the tray. Just having the disc in the drive doesn't help unless the tray is open.

I have a new Macbook Air and for the last few days the fan had run continuously, this is the first time it has ever run, and now it won't stop, the fan starts up as soon as I turn it on. The computer is not hot.Any ideas on how I can fix this please ?

I have a new Macbook Air, 6 months old, and for the last few days the fan had run continuously, this is the first time it has ever run, and now it won't stop, the fan starts up as soon as I turn it on and the computer seems to running more slowy.The computer is not hot but I am worried it may burn out,.Any ideas on how I can fix this please ?

Hello dwb,
Here is the screen shot, just the top half, there are another 10 pages, but I guess this should enough for you to have an idea of waht is going on, bit small I am afraid. No, I don't have any apps setup to run when I open my computer, the kernel, varies between 290 and 305 per cent ish.
Would that PRAM thing help ? I think it may be the computer itself, well something inside, as this the first time that the fan has ever started running since I have this computer, even when I have 3 or 4 apps running.
Thank you again for your advice,
Regard,

Firmware update progress bar appears and computer won't start up

Hi,
I am on OS X 10.6 (the latest developer build, whose build number I can't remember and can't look up because my computer won't start up) and this morning when I tried to start up my computer, it chimed, the apple appeared but then a grey progress bar (like the one that appears during a firmware update) appeared at the bottom of the screen along with the customary spinner. This progress bar didn't update and after 10-ish seconds, it disappeared and left just the spinner. I left the computer in this state for 4 hours and nothing happened. It still starts up in single user mode (but I can't seem to get Open Firmware mode to load) and it starts Windows XP on another partition of my main HD.
When I start it in verbose mode, it says that my catalog B-tree has keys out of order and it is unable to repair them. Also, I get an error message from launchctl: "Bug: launchctl.c:2033 (23930):17: auditquickstart() == 0". Then later on it tells me to convert a few system plist files to launchd (all in the /etc/mach_init.d/ folder). The very last line says "launch_msg(): Socket is not connected".
I would rather not re-install the system, but if I have to, I guess I will. I appreciate any light that anyone can shed on this problem.
Thanks,
Kyle

Yes, they (the third-party utilities) both come on bootable DVD's. As I mentioned, since Snow Leopard was just released in its final version, the developers may be in the process of releasing updates.
Your situation is likely to be a case where the data corruption issue already existed before installing Snow Leopard, and the installation process made the problem more apparent (because something critical was installed where it was affected by the data issue).
It is a good idea to run +Repair Disk+ in Disk Utility on the startup volume before installing a major system update. Actually, I do it before any system-level update.
You should also have a backup (at least of your personal data if not the entire volume), in case something bad happens during a major system upgrade. If you were using Time Machine, the easiest recovery would be to reformat the internal drive and use the Time Machine complete volume restore utility to restore the volume back to the date/time state just before you installed Snow Leopard. Then, after restarting from that restored volume to make sure everything is working, start up from the Snow Leopard installation disc, run Disk Utility and use +Repair Disk+ (just to be sure), and run the upgrade to Snow Leopard again.
If you have a backup of at least your personal data, you may want to reformat the internal drive, install Snow Leopard and bundled apps, install your third-party apps from their original sources, update everything that needs updating, and restore your personal data.
If you don't have a backup, the best bet is to try either DiskWarrior or TechTool Pro. DiskWarrior is very specialized into repairing this type of data problem. TechTool Pro has similar capability, but it is a more general tool with other features.

What does a file folder with a question mark in it mean when the computer won't start?

What does a file folder with a question mark in it mean when the computer won't start?

There are four general causes of this issue:
1. The computer's PRAM no longer contains a valid startup disk setting when there aren't any problems with the disk itself. This can be checked for by pressing the Option key and seeing if the drive appears.
2. The internal drive's directory structure has become damaged. This requires usage of an alternate bootable system to perform the repair.
3. Critical system files have been deleted. This requires usage of an alternate bootable system to reinstall them.
4. The internal drive has died or become unplugged. This is the most likely case if the computer took a sharp impact or there are unusual sounds coming from the hard drive's location.
