I have a client that brought me their HP Pavilion DV6500 laptop (Windows Vista Home Premium edition) that seems to have a severe issue.
When you attempt to power it up the lights above the keyboard all light up and you can hear the hard-drive spin up but then it reboots itself and begins a continuous reboot cycle. Nothing at all appears on the screen ever. The DVD/CD drive spins up momentarily (indicated by the yellow LED) but powers off when the laptop reboots itself (as one would expect).
The only way to stop the continuous rebooting is to press & hold the ESC key; this prevents the computer from rebooting, the lights stay on, but nothing appears on the screen and the DVD/CD drive will not read the recovery disc(s).
I have taken the following trouble-shooting steps:
1) Unplugged the unit from AC power & removed the battery. I was sure to hold in the power button for 30 seconds to ensure the capacitors were properly drained. This reset did not fix the issue.
2) I reseated the RAM and switched the RAM sticks (there are two of them) in trying to determine if it is a RAM issue; no affect with this attempt either.
3) Have attempted to boot into SAFE-MODE many times with no luck.
I'm running Vista 64 and one of my recent windows updates, for the .NET framework, is not able to complete (I don't think it completely downloaded), but when I boot up it keeps trying to complete installation then reboots the computer when it can't, in an endless loop.
What can I do? Does Vista have a 'Safe Mode' or something where I can bypass the normal boot up and be able to get on there to grab my few unbacked-up files, then reinstall Vista? Any other kind of temporary fix? I've been seeing a few weird things for the last couple of weeks so I want to do a clean reinstall no matter what at this point, but I REALLY need to grab a few super important files first.
My Acer 5742-7653 is stuck in reboot loop. It starts to load Windows 7, and then the screen goes black, and it beeps a bit, and theen starts over again. The F2 button no longer gets me into Setup. And the F12 doesn't work. I can't get into SafeMode or Setup. When the problem first began, I could sometimes get into Setup and boot from an external HD which as a diskImage.
I used to be able to remove battery, and remove HDD and RAM, and then it would boot up from the external HD. To get through a busy period at work we set the power option so the computer would never shut off. But this is creating problems with all the Firefox, Adobe and Windows updates that want to run.
This is running on Windows 7, 64bit.
How can I determine if this is a problem with the HDD, or the RAM? or Motherboard? What else could it be?
I have an HP Pavillion dv 6500. I am having a similar battery issue that has been discussed in other posts. The original battery "died" a couple of Months ago, and I purchased a new one from HP.
Now the icon in the System Tray shows "0 % available (Plugged in, not charging)". I installed the HP Support Assistant, and ran the Battery Test, The result was: Status: "Calibrate" and Current State: "Unknown".
Problem is that part of the "Calibrate" procedure is to allow the Battery to charge-up (to 99 to 100% charge), but I am unable to accomplish that, since the battery is not charging - the charge remains at 0 %, and never seems to charge.
Dropped my computer and now it wont boot up. Instead it just keeps turning on and off. The screen is also cracked. HP tells me that the hard drive or motherboard have been shifted with the impact and are not being detected properly causing the power cycling. They are offering to fix it for $400. I would like to attempt to make the repairs myself, if possible.
I change windows vista to xp to my hp dv6500 laptop i find all drivers except nvidia video driver , when i try to install the driver " Nvidia setup program couldnot locate any drivers that are compatible with your current hardware.setup will now exit" .

I cleaned my over-1-year old DV6563 laptop since the heat sink was filled with dust inside. Anyways, I got everything back together, but unfortunally the inverter lamp on my monitor went dead (I got a replacement off Ebay and the monitor works again).
However I have a slight issue. Every time I close down the laptop lid, the screen stays on (it doesn't turn off the screen). I even set windows to go into stand-by when the lid is closed and it does not turn off the screen or go into stand-by (unless I press Fn+Sleep).
I even installed Windows XP to see if it was a Vista issue...however the problem still exists. I do have the lastest Nvidia drivers too.
I have upgraded from win8 to win8.1 on my HP Pavilion model 15-e011nr. I can't reboot and get to the desktop. The notebook PC goes into a cycle of automatic repair, then gives a choice to restart or try advanced options. I tried to use F8 or delete to go into safe mode. Do you hold the key down or continue to press it repeatedly while the computer is starting up? Or is there another method to get to safe mode.
I have an Ideapad Y510P with 24G SSD and Windows 8.1. I uninstalled the Express cache by a mistake. So I want to re-install it. Unfortunately, the install program told me that I need to reboot the system even I tried to reboot or shut down the system several time.
i get a black screen and when the screen comes back it says "display driver crashed and successfully restored" and everything was fine. well today it happened again, and it didnt successfully restore and the screen stayed black, so i turned the computer off. I turned it back on and i had an assortment of Black lines, white and fading colors that would appear and reappear and now i cant even see anything on the screen but the whacky colors and lines, and i cannot boot up,
I flashed to f.24 with no problems before HP yanked it. Just now I flashed to f.26a, and now I'm noticing that with every soft reboot the laptop recycles power - power light goes off and back on, even doing a ctrl-alt-del on a DOS prompt!
I'm not 100% certain it was this way with f.24 as I haven't had the need to boot to DOS until now (just whacked the stock HP OS). But I sure don't remember the computer recycles power with every Windows reboot.. Is this how HP is fixing the wakeup and/or black screen problems that I never had?
This can't be very good for those who have a spinning platter hard drive - I got one myself I got the 160SSD+250HDD.
I have a HP dv6500 running Windows 7 for which I want to upgrade the pci-e mini wifi card to one of the intel cards available on Newegg, or perhaps a 4G card. However, I have read that the stock HP BIOS has a whitelist for wifi cards, and only select cards will work.
I have located a modified F5A bios that I am willing to try: [URL] .....
I have also heard that flashing a BIOS from Windows 7 will damage it, and the recommended solution is to reinstall Windows Vista. Is there some way around this? Could I perhaps use a PE CD?
I am working on a laptop of a friend of mine and he wanted to upgrade his mSata drive after his old drive was corrupted and no longer boot into windows so I purchased a new mSata 256 gb and trying to restore windows 8.1 but it keep going into an infinite loop, I did disable secure boot but still no success..
My Inspiron 1150 was in normal use last week. Next day I switched it on and it came up with the start screen, Dell, Inspiron 1150, the bar at the bottom screen fills with white as usual and in the top right of the screen it shows F2 setup and F12 boot menu.
Entering either of these does nothing and the whole thing goes round in an endless loop hence the title of the thread.
I have checked as far as I dare inside, checking the memory firmly inserted, battery is fine and the HDD looks OK though I don't have the gadget to check it like the old ones with 2 lines of pins.
Someone said it might be the CMOS battery but since the on-line manual doesn't show where it is, I can't replace it (even if that is the possible cause).
i have a new Lenovo IdeaPad Z510 (i5 Full HD with Nvidia Graphic Card). I bought it on 7th October 2014 and everything was fine under Windows 8.1 N Pro x64. But today when i started my notebook, i had a black screen for a few seconds and then it stuck in a reboot loop.
1. i press the power button 2. black screen for a few seconds 3. reboot and back to step 2.
i tried already the lenovo button, but this results in the same problem as above. I also tried to boot into bios by pressing every F1...F12 key and also Fn+F1...F12 key. And last but not least i tried to boot from Disk (Windows 7 Home Premium 32 and 64-bit, Windows 8 x64, Windows 8.1 N Pro x64 and Debian latest stable) but it didn't work, too.
Recently I purchased a u410 and it has been running great for a few weeks but this morning instead of waking up from hibernation like normal it seems to be stuck in a loop of displaying the lenovo logo then a blank screen with a few seconds on each. This has been running continuously for hours while I try to run down battery in an attempt to reset. I have no bios access during the loop and it will not boot to any usb media. I am now wondering what I should do since it already has data migrated from my old machine and don't exactly want to start over. Is there anything that can be done other than returning it or sending it to lenovo support?
I just bought this laptop. It's been 1 week and I was playing a game then I saw blue screen and forced to reset my computer.After that I couldn't start Windows 7. It stuck on startup repair and can't repair it somehow. I tried everything but noting is working. I tried to use the Dell cd for factory settings but still can't use windows after the first install. I am going to copy my problem signature. Is this Virus and what cause it?

I am stuck with a dell E5440 here power light comes on and then laptop switches off and back on again and just repeat itself! I did not tried anything yet. It is i5 vpro and I installed 1TB HDD few months ago, it has been working no problem since yesterday.
I was trying to boot in safe mode so i went into boot options checked safe boot and minimal. Then when I restarted, it just kept restarting over and over again. I can't get to safe mode. I can get to the setup and boot manager. I tried running diagnostics and there were no errors.
I try to boot my pc but get the error code 0xc000021a, then it restarts and says preparing automatic repair, then the same BSOD error pops up and the cycle continues. I've tried just about every 'fix' I could find on the internet. I purchased this computer with windows 8 pre-installed, I do not have a windows 8 repair DVD.
Upon further research I've been lead to believe it has something to do with winlogon.exe or csrss.exe, which makes sense, seeing as I cannot even log on to my computer. Other forums suggest it could be caused by 3rd party software.
As far as I can see, all I can do is access the BIOS. I have no files that can't be easily replaced so even if I could somehow factory reset it that would be great, though I'm not sure if that will fix anything or is even possible in my current position.
My laptop has been messed up ever since I updated it.It all started when I got a notification to update to windows 8.1. It was all good until the next day when I started it up and it would not pick up any Internet connection even though I knew my router was working as I could get an Internet connection on my mobile. I went to the network and sharing center and it said there that it was disabled so I right clicked on it to enable it. After I clicked it, my laptop went to a blue screen and came up with the following message something like this: we've encountered a problem, we're gathering some error info and we will restart your device.
So, it restarted and I tried to re enable the network again and the same thing happened. After about 5 tries the restart thing kept happening. I didn't know what to do so I thought to just restore the laptop. I did that and now it's just in this continuous blue screen restart loop. I can't even get to the log in Window, it just keeps going to the blue Window and then restarting.This is a new laptop, not even 6 months old and it was fine until I was told to update. I'm thinking of just taking it into the repair Centre as I have warranty and I feel as if I can't fix this problem myself as I can't even get into my actual desktop.
