Preferred Solution: Laptop won’t boot up

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

My Toshiba laptop was working fine. Our internet provider is Comcast. Comcast has replace McAfee antivirus with Nortons, and I was trying to migrate from McAfee to Norton according to Comcasts instructions. Now the laptop will not boot. This is what I get:

My laptop had a problem with the hard drive (or so it seemed because it was unable to load up) What happened with the laptop was I tried to turn it on, the computer will load for a few seconds, then it will turn off. (So it never made even to the Windows logo screen).

My friend took it to the technician and the technician said it was a hard drive failure and needed to buy a new hard drive and install Windows onto it. The technician was going to charge $165 for new hard drive and Windows installation.

I thought $80 for a new hard drive than another $85 for a installation was overpriced. So I ordered the hard drive on my own and planned on replacing the hard drive myself.

So, I replaced the hard drive. What is going on now is that if I press the power button, I see the red light on the power button. Then in less than 5 seconds or so, the computer goes off. There is nothing on the screen during those 5 seconds.

This laptop is quite broken down, the CD Rom sometimes does not work. But regardless, with less than 5 seconds, it was quite hard to even eject the cd-rom. So I am not quite sure how am I supposed to go on and continue with the installation and such if the computer does not even turn itself on.

Now, is this really a hard drive problem or something else? Please help. Thank you very much in advance.

A:Laptop hard drive replaced, won’t boot up properly, shuts off in less than few second

$165 is actually a reasonable price.

If you remove the new drive, does it still shut down in 3 seconds?

Yesterday I ran into some issues with my computer hardware - in the middle of a LoL game my computer randomly powered off instantly with no warning or anything and would not turn back on. After hours of attempts I realised when I removed the graphics card (Nvidia GeForce GTX 960 1x6pin connector) from my system it would power up on the integrated graphics, the motherboard green light (ASUS Z87-K) is always working also. I thought because the computer wouldn?t power up at all that there was a fault with the power supply (Cooler Master 500W) so I purchased another one (Corsair VS550W) and tried that. Still no power up with the graphics card connected, at first it would work without the graphics card also but after some tampering, replugging and cable managing now is not turning on at all, even WITHOUT my GPU attached with this brand new PSU. I?ve had the PC for just over a year and was advised maybe my old psu had just died but that appears not to be the case. I?ve also tried removing non essential components and booting but still nothing. Maybe there was something I could do in the bios and alter the settings? I did used to run the multi display bios setting which would allow me to use the integrated graphics witn one monitor and the gpu graphics with my main monitor just because I didn?t have two VGA ports (I use VGA because I have two old tv?s instead of dual monitors)

A:PC won’t boot at all

First of all, the vs series from corsair is the lowest quality unit corsair sells. It is NOT designed nor intended for use with a real video card. Even corsair says as such

Installing that pw supply did nothing for troubleshooting.

Here is what I would do;
1 First and foremost, get hold of a pw supply that is actually designed for gaming or other stressful endeavor
2 Install the quality pw supply
3 Now test with and without your video card. It may be that your video card failed however no one can tell you until you use parts that are designed for what you are doing with the system

Hi, I?m not %100 sure if this is the right forum/topic, but my desktop is an Alienware x51 R2 running windows 10 and BIOS version A09 if that matters. My computer attempts to boot up and gets to the screen where it has an f2 and f12 boot settings which I fiddled around with a little, then gets to the Alienware loading screen before windows login but after about 5-10 seconds the screen goes black then the process repeats. I use this computer for mostly gaming and YouTube, studying when needed. This all began when I was playing a game, I saved the game but left it open, then went to YouTube and my screen just went black. I tried Alt f4ing a million times but eventually restarted my PC. Everything was fine until I tried loading up the game, all of the sudden my screen went white, then to a windows screen where it said windows couldn?t be loaded and asked me if I wanted to troubleshoot or reset my computer. My computer was a little cluddered and I thought a fresh reset would fix everything, but I was incredibly stupid to think that was the case. PC Reset got to %100 then it tried to reboot. Essentially, my computer threw itself into a boot loop and when the f2 f12 screen comes up, I mess with a few settings but nothing works. Please help me, and I can?t get into my computer which is why I can?t get you specific specs, sorry. To share my pain I typed this all on my 5S, just thought I might lighten the mood.

Hi guys.
I just got my XPS 15 9560 delivered from the online order yesterday around 19 hours ago. Last night I tried to power it on and undergo some setup as usual for a new laptop. All seemed fine. I did some research for a good anti virus program to have and I installed a trial for Bitdefender. My internet was not running well so I got a lot bunch of unsuccessful of windows updates. I thought to power it off and wait till the morning to do it. In the morning I powered it on to take a look with this beautiful 4k display when on my way to school. 5 minutes seemed fine. When I got to the school and sat down powering it up, got to the home desktop screen then 2 seconds later I got a blue screen and all these accumulating screen tearing flickering saying it will do the restart for me. I let go for 5 minutes but no progress on percentage status. I forced power off and when I tried turning it back on it won?t start but the light bar in the centre appeared orange and white repeatedly. After a few restarts I now totally can?t start it up anymore.
When I pressed on the power, I only get 2 orange 4 white 2 orange 4 white 2 orane 4 white then a little pause then another 3 times of the 2 orange and 4 white then the fan powers up really loud and it shuts down. ( the screen never appeared to be turned on in the process)

I have a Lenovo laptop. Out of the blue, windows does not boot up. When it starts, I see the Lenovo logo. Sometimes it says starting automatic recovery? ornaomehibg of that nature. It then goes to a black screen and just stays there.

How can I fix this, without losing my data? There are definitely files I would want to save before erasing everything, but would be fine restoring previous settings and losing programs as long as i didn?t lose all my photos/documents.

I don?t see anyway to start in safe mode and/or do a system restore. I am able to get to BIOS. From bios??, is there a way to access safe mode/system restore or a way to do this from BIOS without losing all my files?

Hi Koldys,Thanks for posting.Apologies that your computer is not working as expected.Have you tried taking the battery out and using the adapter plugged in?  If it works, then it would indicate the battery has failed.  If it still does not work, then the charging/power circuit is probably at fault.  If that's the case, the motherboard would have to be replaced.

Any suggestions, we thought about doing a CMOS reset! We have already done the whole, take the battery out and reset thing! Any help will be greatly appreciated. By the way, the last time we used this computer it worked, but that was like two years ago! It just had problems with the power jack. Maybe we did something taking it apart? My husband was very careful. We just don’t want to spend a ton getting it fixed. Also, how do you tell if the motherboard is bad? Thanks, Misty

A friend?s ThinkCentre A57 Type 9202 currently refuses to boot.  At first, it locked up hard a few times during routine operations, but now generally doesn?t even display the initial BIOS screen.  More specifically, 90 times out of 100, when the Power switch is pressed, the screen remains blank and the fans continue to operate at high speed.9 times out of 100, the initial ThinkCentre screen displays, but nothing further, and the fans return to low speed after about five seconds (as one would expect normally).1 time out of 100, the Windows screen offering to start up in Safe Mode displays, but nothing further, and the fans return to low speed. One other oddity is that the USB dongle for the wireless keyboard frequently displays no indicator light, even though a digital camera subsequently connected to the same port indicates that it?s charging. This is most likely a red herring, since the same keyboard works properly when connected to a ThinkPad, and in any case, POST should detect and protest a missing keyboard.  (Shouldn?t it?) I removed the HDD to an external USB cage and copied its data to another machine, so that?s working properly.  My friend reported that removing the drive had no effect on boot-time behavior. This has otherwise been a fast and reliable machine, and I?d hate to see it junked?especially since I recently spent a day upgrading it from Vista to Windows 7. The problem is similar t...

If it is asking for a login account password I assume you would use the password for your Microsoft ID.

If it is asking for a UEFI or BIOS password you need to find out who set one.

If you are really still running Windows 8 I strongly advise that you get the free upgrade to the still supported 8.1.

Ok, so if I were to try and help anyone, Id only be able to tell them how to make a bad problem even worse.

I have an HP DV2000 laptop running a Windows Vista Home Edition (in english) it came with.

I was getting random warnings from my Norton 360 (a very lousy software, mind you) about a Vundo infection. Norton scanned my computer a couple times, but it never went away (neither the virus nor the Norton software).

I ran Hijackthis a couple times and identified a couple of .dll files in my Windows/System32 directory with random letters as names. Hijack this couldnt fix them, so I booted into safe mode and deleted all of them but one. This last one was "in use by the system", Vista warned me.

Then I booted up again normally. I unchecked as many boxes in msconfig as I could understand, including the random letter dlls and a MS Server random letter file.

I ran a Uniblue registry cleaner software (which I own) and fixed a couple registry lines.

Then, without restarting, I ran regedit and hit F3 looking for entries referring to the last random-letter.dll file. I deleted a couple of the first ones, and then decided to modify each entry I found referring to the random-letter file into blank. I swept the whole registry three or four times, and every time I found a new entry. Just to make clear, I changed only those that had the whole "UWLDJKU.dll" string (not quite those letters, but something close to it).

Then I just got tired and rebooted.

I was working on my computer when the monitor spontaneously went into Power Saver mode and turned off. I was forced to do a hard shut down using the power button. I tried restarting the computer and got to the Windows logo before the screen went into Power Saver mode again. After another hard shut down, I restarted and only got to the Dell screen before losing the monitor again. A few more tries produced various results – in some cases, the monitor continued to go out from the Dell screen, while in some cases it would just sit on the Dell screen indefinitely, there was even one time through that it reached the auto-chkdsk stage, but promptly died a few minutes into that. I can select F2 or F12 from the Dell screen – but it doesn’t actually enter the BIOS setup or the Boot menu before the monitor dies again. It seems as though it sometimes finishes POST and other times it doesn’t, though I don’t hear any beeps in either case. (Yes, there is an internal speaker connected.)
It strikes me as being a problem with the BIOS or the video card – but it is really hard for me to tell. There could be a problem with the OS on the drive, but it doesn’t seem to get far enough in the boot process for me to think that’s the problem. I’ve read a number of posts with similar symptoms, but they don’t seem to ever run into the problem of not even being able to get into the BIOS setup or Boot menu, so it’s hard to know if they&rsquo...

Hello. I have Windows XP Home Edition, SP2 on two separate bootable hard drives in my Dell XPS B1000r. I have my 80 GB main hard drive and a 40 GB extra hard drive. I mainly boot from my main 80 GB hard drive, and thats the drive that wont boot after I changed the drive letter.

I wanted to rename the Drive letters associated with each of these hard drives. I was able to change the extra hard drive using the Disk Management option.
