Pavilion G6-2264ca blank screen - BIOS corrupted?

Hello, I've been having problems with my G6, it's about a year old and suddenly the bottom half of the screen was pink and green colors for about a day, after that then whenever I booted it, the regular image would flash on the screen for a second and then go black, and now it just stays black. When I press the power button, the wifi and power LED's come on and I hear the DVD drive start up as normal, but I'm not sure if it goes beyond that because all I see is a black screen.
I tried:
-Hard reset
-Reseat RAM
-Unplug one stick/other stick/both sticks of RAM, unplug HDD, all of the above
-Win+B when booting to recover BIOS, nothing seems to happen but it does give me a 2 blink notification on my caps lock, which supposedly means a corrupted BIOS?
-Tried recovering BIOS via bootable flash drive (Trying both wincrisis and PheonixTool methods)
-Swapped motherboard out for one I bought online, STILL gives me the same problem and error code (2 blinks).
Could it be an extremely rare coincidence that both are corrupted, or do you think it's something else?
Help is appreciated!
(Or if anything, does anyone know how to view your whole hard-drive with another computer? I hooked it up to my desktop and I could only see Public, Default, and Admin under Users and they were all empty in both Windows and Linux, even when I tried to take ownership with windows!)

Hello derf321,
I see that you're having an issue with the notebook loading to a blank screen. I will try to help you with this.
Reading over your post, you've done the troubleshooting for beep/blink codes. It is possible that there is other faulty hardware.

Pavilion p7-110c blank screen on start-up

My Pavilion. P7-1107c has a blank screen on start-up. There is a white flashing underscore mark in the upper left corner. I have tried the f-10 keystroke recommendation with no success. Lights and fans are operating, and the cable is securely connected. There is a one-second display on the monitor of the hp logo (the hand with the building blocks) a few seconds after start-up, which immediately disappears.

Hi,
Your PC is listed as coming with Windows 7 64bit - if this is correct, try the following.
If you don't already have one, use another PC to create a Windows 7 Rescue CD. Download the ISO from the link below.
Windows 7 64bit
You should use an application such as ImgBurn to burn the ISO to a CD - a guide on using ImgBurn to write an ISO to a disc is Here. Once created, or if you already have this, insert the CD into the PC and restart to boot from it. Select the Repair option.
Select the 'Repair your Computer' option and follow Option 2 in the guide on the link below to run Start-up Repair – you may need to run this 2 or 3 times.

HP pavilion dv7-6c21nr blank screen

Please Help! My husbands Hp dv7 screen won't show up. The computer itself works just fine and I have been able to use the computer via the HDTV we have but I need his computer screen to start working again so I can do my quizzes and give the kids back the TV. The day before the computer was working fine and now the screen refuses to show up on the computer screen. I even downloaded and installed the new BIOS and it's still not working. I'm hoping we don't have to send his computer in to be fixed and there is quick solution to the problem

Hello jschronce,
I see that you are having display issues with your HP computer. I have a couple of suggestions that may help with the issue. Here is a link with troubleshooting steps to correct common display issues. Follow the steps in the link and it may correct the issue.
The first step I would suggest is testing to see if the screen stays blank when inside the BIOS. This would let you know if it is a hardware or software problem.
Follow these steps to enter the BIOS of the computer.
Power the computer off
Power it on and immediately start tapping "F10"
This should open the BIOS utility on the computer
If you are unable to get this screen on the laptop display that means it is an issue with the screen itself. Since the computer is working on an external display the graphics card should be fine.

HP Pavilion g4 notebook-- Blank screen at start up

had the monitor screen replaced, did not solve the problem. I connect to a stand alone monitor the computer works fine. Using Windows 7 Home. Any ideas?

With it connecting to an external monitor and working just fine, it would indicate an issue with either the lcd or the video cable. Usually, a completely black screen is the lcd panel itself. But you said you had it replaced...
Go ahead and boot up with the external monitor. Once you are booted up, press Win+P. That should bring up the shortcut for your projector screens. Select Laptop only. Could be a setting just didn't get back to normal.
If that doesn't work, I would take it back to whoever replaced it. Did they test it before giving it back to you? Did it work at all after having the screen replaced? I do this kind of work all the time and would lay 10 to 1 odds still that it is the lcd panel. If it hasn't worked at all, I would have them double check to make sure everything plugged back in correctly, done that a time or two... If they are positive the screen is good, change out the cable. In my experience, one of those has to be the issue.

HP Pavilion p7 1040L bios corrupted

My PC is an HP Pavilion p7 1040L.
I updated the bios on Windows 7 Professional 64-bit, but my PC froze for a long time and I had to shut it down.
The bios file was downloaded from here http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=cp-102192-1&cc=id&dlc=en&lc=en...
When I turned the PC on, there was just 8 times beeps with orange flashing power button and no video signal. After 8 beeps, the PC was still on and power button turn blue but there was still no activity and blank screen.
From the documentation I know that the bios has been corrupted.
I have tried the boot block recovery using USB flash drive with several rom names like HPBIOS.ROM, AMIBOOT.ROM, HPBIOS.BIN, etc. but the flash drive only accessed for several seconds but then no activity. The rom file I used was the file from bios update since I don't have the current bios.
Please help.

I see that this model first introduced in June of 2011 - so it should still be in normal warranty.
I could contact support for your country and request a service event be scheduled to get it repaired - this likely needs a motherboard replacement.

Blank screen after bios update

Hi everybody!
My friend asked me to take a look at her computer. It was quite old HP pavilion 6525en. Before reinstalling windows I checked that she got first version of bios and decided to upgrade it. Sadly, after reboot I found myself in deep problem. There was a blank screen. I decided to look around in internet and found that its a common problem. (have updated lots of bios, but never happened stuff like that). So I found couple articles about Phoenix crisis recovery and decided to try that. Should I know something before I dive in? I know that I need thumb drive or usb floppy and how to enter CRM (crisis recovery mode), but all these sounds scares me a bit. How long does beeping takes after thumb drive stops flashing? Can it overheat, coz I found that fan won't slow down? can anything burn during this? (I know, lots of questions, but I'm cautious, coz I just wanted to do a good job for my friend and now it seems that I might have to get her a new computer ) p/n: GT391EA#ABB. Any help would be appreciated.

There is no harm in trying crisis recovery, the recovery should take 2-5 minutes, you should get some sort of signal or sign when it is done, most systems will automatically restart when done.
I don't know of any reason it would overheat during crisis recovery.

790FX-GD70 - Blank screen after bios (never shows Windows Loading screen)

Setup:
Phenom II X4 955
790FX-GD70
750w PC Power and Cooling, Inc PSU
Western Digital HDD
ATI HD2900XT
x-Fi fatality sound card
Windows XP x64 Pro
So hardware wise this setup has not changed in over 8 months. However tonight I restarted (first sound cut out so i decided to reboot). Lo and behold on the reboot, it will flash the MSI splash screen and allow me into the bios but when I go to boot it will not show the windows loading screen. It sends me to an active (my monitor doesn't go into standby) black blank screen (no text or error msg) and won't respond to any keys.
Anyone else ever have similar issues?
Thanks
Verik

I appreciate it guys. I did a little more digging around the internet and found it was most likely due to a corrupted MBR. The fix usually involves booting from a win xp disc and typing in the command "fixmbr" in the recovery program. However I inserted my win xp disc and it simply went black..... then loaded up windows just fine. Pulled the disc out, did a normal restart and it seems to have solved itself.... At this point I'm not sure entirely what it did but I'm just being thankful its working haha.
Appreciate the input guys.

Pavilion H8-1240t boots to a blank screen ! ?

Every so often my 2 year old Pavilion with an AMD Radeon 7070 video card will boot to a blank screen and will continue to reboot over and over again until I pull the plug. Aside from this one snafu the PC works great !
The way I got it to boot right today was by reseating the video card and pulling out the battery on the motherboard for a few seconds. Is this common? What exactly is causing this problem? HP Tech offers no answers whenever I call them?
This question was solved.
View Solution.

Ok thanks for you reply..... I do not think it is the video card because my original H8-1240t came with an Nividia card and I sent it bacck because I was experiancing the same problem...... Is there a new bios that I should upgrade too?
The PC is working fine now.
Also my other related problem is that I have been unable to boot from my DVD rom drive. This machine never seems to reconize any boot disk that I place in it even though I have tried them successfully on other PC's.
The boot order setup screen is a bit confusing.... please explain.

Blank Screen on Pavilion A6600F

Mother-in-law's Pavilion A6600F mini tower seems dead.
Completely blank screen, no splash screen on boot-up attempts.
Confirmed that monitor works on another computer
Power supply light on the back of the unit is green and the power button on the top front of the unit turns on.
The power supply fan, cpu fan and back vent fan all run fine.
No splash screen and no beep on startup.
Replaced power supply with new one and no change.
Removed modem card and re-booted with no change.
un-hooked hard drive and CD drive and re-booted with no change.
Removed both memory sticks and re-booted with no change.
Only motherboard hooked up and still no splash screen and no beep on start-up but new power supply and all gans running fine.
I thought perhaps bad motherboard graphics adaptor but if I can't get to the bios to disable it I don't know if adding a discreet graphics card will make any difference.
Any help Appreciated!

Hi..
The only to check if the motherboard is faulty or no is the beep test.
Follow this to check out.
1. Remove the all memory sticks (RAM's) from the PC.
2. Plugin the original power cord.
3. Turn on the desktop without any memory sticks on the motherboard.
4. Listen to any beep noises you get.
5. If you get any beep noises (1-1-1) without the memory slots that means the motherboard is working fine.
But,
If there is no beep noise without the memory's, the motherboard is faulty or dead.
This could also be the processor if there is no beep noise.
Both the components cannot be tested particularly apart from the above test.
In this case all the other components will work fine but its the motherboard.
Also if the motherboard is beeping without memory sticks then its the memory sticks.
Check out on the memory's then.
If you have any other questions or this does not fix the problem, REPLY.

My pavilion dv4-1070 got stuck on a blank screen and numlock and caps lock LED are blinking... it happens when i update the BIOS.. please help... thanks

Hello,
I see that you're having an issue with the notebook giving you a black screen. I also noticed you said only the NumLock and Caps lock is blinking.
Now, the BIOS update could have because this but we won't know until you let me know how many times the LED blinks.
Here is a chart which will tell us what's causing the issue.
Please let me know the outcome.

Try reading this thread
However, not every blank screen will lead to broken GPU, start your own thread so that everybody can help to troubleshoot it.

Hi s.cheslik,
It seems your MacBook Pro will not boot properly and it displaying an error message. Based on the information you have provided, it appears your MacBook Pro needs to be serviced. The following link should help you get started with the process and has links with additional information on topics such as warranty and service pricing, battery replacement, and express replacement service.

Blank Screen (Raid/BIOS Problem?)

Have been running a stable setup for several months with the following components:
845 Ultra ARU (PIV 1.6A)
Gainward Geoforce III 128 MB
2 - Seagate Barracuda IV
Kingston 512MB DDR
Enermax EG365P-VE
Windows XP
All running at default values (i.e. no overclock). Very stable until this weekend when the screen went blank while in rest mode (no programs running). The system did not respond to anything other than the reset button.
The system boots normally until it attempts to start Windows XP (at that point producing the same blank screen no response/no warnings or error message setup). BIOS settings appear unchanged and the array appears to be functioning during the startup (sends back that message and correctly identifies the 2 disks). Attempting to repair the XP setup (using the XP install disk) does not recognize the array as a properly formatted device (it sees it just says the format is unknown). Booting on floppy with the array drivers allows a directory of a third disk that has always been installed on the secondary IDE controller (it's not bootable just a backup of old information) but does not recognize the format of the arrayed devices.
Thinking out loud:
Could a BIOS flash help?
Are there any other suggestions before I'm forced to have to reformat the array?

Wasn't able to come up with a bootable floppy with FDISK on it. Copied the data onto the small drive hanging off the onboard IDE controller and attempted to reformat the array.
However the XP format fails at various stages on the formatting. Checkdisk also fails in phase 4 (sometimes right away and other times after a period of time). The error messages are non descriptive (just XP was unable to complete the function) and after the failure the drive is not accessible until the next time the computer is turned on. Tried to delete and reinstall the array but that doesn't appear to do anything (the data is still there which surprised me). Is there a way to completely wipe out the array and start over?
Don't think it is a jumper issue (it worked for several months without a glitch) but will check. Can't see what would have happened to the driver but will try to reinstall the motherboard driver (I understand that has the RAID driver as well). Could try and reflash the BIOS?

I have a HP Pavilion g6z-2200 upgraded to 8.1 got a blank screen,

i have a HP Pavilion g6z-2200 upgraded to 8.1 got a blank screen, revert back to 8, now i can't get any of my apps back because they want me to upgrade to 8.1 how do i know if it's safe?

Hello @061210 ,
Welcome to the HP Forums!
I would try updating to Windows 8.1 again. Make sure all of your Windows updates on 8 or done before the 8.1 update. Then, as soon as you do the update, look for any new Windows updates and install those.
Worst-case scenario, you have to revert to Windows 8 again, but I doubt that will happen
