My laptop does not start after cleaning

Hello
I knew an overheating problem on my laptop.
I therefore decided to remove a processor heat sink and empty dust. It was released with processor...
There was a huge load of dust, so I cleaned it, put new thermal paste...

Now computer laptop does not start loading Windows.
It checks only the CD, HARD disk, and that's it.
Screen is blank, ON the indicator led is on.
Two fans periodically start to turn (when they stop radiator heat - so the processor works)

Where is the problem?

Thank you

Hi Dubas,
You can access the BIOS when you try to start your laptop? This can give you a clue as to why the OS will not charge.

Kind regards

    My Dell XPS 1530 stopped working after installing vista sp2. He gave me instructions for installation, step 1 of 3 and it went all that they way up to step 3 of 3 and said its closure and never came back...
    Please let me know, how to start the laptop.

    Thank you for visiting the Microsoft Answers forum.
    Because your computer does not start until the desktop computer, we were able to try the system restore to a point before you install SP2.
    Thus, with the computer is shut down. Press the power button, then press on and press F8 until you see the startup options, and then it will give you the ability to boot to the last known good configuration. (select it).

    If this does not work, you can try to boot from the Vista DVD and use the recovery console to perform a restore of the system to another point in time.

    Post back with the results.

  • Acer laptop does not start after the blue screen

    After I got a blue screen (flashed by too fast to see the error message) when I try to reboot my acer 5610Z laptop computer with vista home edition, usually nothing happens at all. sometimes windows is trying to run the Startup Repair tool, then crashes and only a cursor flashing at a black screen.  Tried to open the case and clean the Fan & Heatsink heat to air without effect.

    The blue screen came a few days after I started using a new USB mouse, but the fan seemed to get high a few days earlier.

    But I noticed it will make the road to startup repair only if the battery is in, and never if only the power cord is attached.  Also, if I let the computer sit for several days, it is more likely start (even though he never passed from the Startup Repair).

    1. try the system restore.

    2. try to do a startup repair disk.

    3 acer Recovery Options.

    4. contact Acer.

    Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.

    Try a restore of the system once, to choose a Restore Point prior to your problem...

    Click Start > programs > Accessories > system tools > system restore > choose another time > next > etc.

    See you soon.

    If the above does not work, try to make a Bootable ERD to do a Startup Repair:

    As is the case with most computers/laptops these days, they do not come with good Vista disc to repair only the recovery disks.

    As your grave in the category above, download the ISO on the link provided and make a bootdisk of it.

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

    When you have changed that, insert the Bootable disk you did in the drive and reboot.

    You can make a tool to restart system, System Restore, etc. with it.

  • Laptop does not start after spilled liquid

    I spilled liquid everywhere in my laptop yesterday. And now it does not work!
    The thing is, I could activate it yesterday after I poured the liquid, it seemed ok.

    So I just turned off and left to dry.
    But it is not today.

    What should I do?

    Hello

    This is a really bad story and I put t see any chance of getting the laptop works without any replacement hardware.

    I think we are ve got the worst case. This means you have a short circuit that could damage the whole motherboard. :(

    I think you should certainly contact the notebook computer technician for a control.

    But it sounds really bad, Buddy :(

    However, good luck

  • Laptop does not start after Windows update

    I have HP laptop with Windows 8.1.

    It no longer starts after you install updates.

    It has happened before several times. I used system restore and it should correct the problem temporarily until the next time for the installation of updates.

    Now I can not even run system restore. He says that I have an administrator account.

    Help, please.

    The process I'll tell you will solve the problem, but it leaves a few effects. All the installed update will be uninstalled the version they had when you have installed 8.1 windows and programs in your programs (x 86) NO program file in the C: drive or the drive where windows is installed must be UNINSTALLED. The uninstalled programs will appear on your desktop as Applications.HTML removed. If you have any problem with the effects that I mentioned that process as follows:

    1. at start up press F11 to enter recovery.

    2. go on recovery to solve problems.

    3. then in troubleshooting, click on refresh your PC.

    4. wait it ends (it takes about an hour)

    5. your system is restored.

    Hope this helps

  • Windows does not start after cleaning in Virtual Machine (XP)

    I now this is twice, using a backup after the first cleaning left me in an unbootable state.

    The full up, not cleaned up, vm works very well.  Boots, tracks and even did disk defrag very well.

    But, after you run the virtual computer cleaning off (even if I have to force the power down after that XP gives me in the trunk to disable screen machine... is it she?) the next time it is said there is a disk error and I get the BSOD.

    (though I must not force power down after that XP gives me in the trunk to put off the screen of the machine

    Whence this Virtual Machine, VMware which product was first created with?

    Also... To help understand what components are, how best to provide comprehensive diagnostic information is to use the command "Collect information to Support" the Fusion of VMware (menu bar) > help > collect Support information and then attach the .tgz file it created on your desktop for a response post.

    Also, since you have a backup (and should always before performing disk cleanup) I would start with a new copy from the backup, and then start Windows and run chkdsk c: /f in command prompt and let next start-up schedule, then restart.  So make sure that it starts towards the office okay, then stop and start the cleaning and see if it makes a difference or proportion still BSOD.

    Also if you are running AntiVirus software on the make you Mac that you're out of the Virtual Machine (s).

  • Laptop does not start after upgrading CPU

    Hello

    I have a dv2528ea and I decided to upgrade the processor and the RAM. According to the manual of the T8300 is compatible, so I bought one on eBay (so-called new). When I powered the laptop, the bios screen appeared as usual, but nothing more happens. Among the options available in this screen only works the "ESC" (boot messages I think). I can't access the configuration. The CPU, RAM, HARD drive and DVD drive is correctly detected, the BIOS and video BIOS are "shaded" don't know what it means.

    I know that I didn't break something because after putting the T7100 back in place, the computer worked fine.

    So my question is: is the burned T8300? Do I have a bios problem?

    I've never updated my bios (since 2007) and the CPU is not physically damaged, but this last part can doesn't mean anything...

    Thanks in advance, Pedro.

    Hi, Pedro.

    I hope it will do the trick.  F.0Une is old and I think that's the reason why your processor does not work.

    The problem is that you are under Windows 7.

    You can put Vista on it and flash, or do you know how to make a flash out of the file based BACK?

    I don't know how.

    I'm saying that you are taking a considerable risk if you flash in Windows 7.

  • laptop does not start after you install a new hard drive

    HP G60-630us laptop... .replaced hard drive... .installed 3 boot disks... After you remove the last drive, when you click on continue it is supposed to start... .it reads no boot device... . If put you the first disc to start, you end up back where you started... I changed the boot order and put the hard drive first... even starts

    Hello

    That sound great for the hard drive.

    With regard to the problem you have with Windows activation, it's because your laptop is listed as originally came with Windows 7 Home Premium - as I mentioned in my guide for the creation of a sale installation disc at retail, the image that you use needs to be also be Home Premium - IE you cannot move to professional or ultimate edition as the key on your COA label will not work for a different version of Home Premium and there is no way around that.

    The image that should be used is on the following link.

    Windows 7 Home Premium 64-bit.

    You will need to create another disc of installation using the above Image and then use it to reinstall Windows 7 - the activation methods I described previously, then will work fine.

    Kind regards
