I installed ssd new mobo still black screen replaced ram,checked connection ac/dc you name it still black screen no Compaq logo nada. I contacted hp no reply. HP no warranty and no assistance policy. I'm think its lg LCD/monitor not sure if customer overheated unit, no spills where found inside reply

I'm using my tv right now with it, it works fine hooked up to a TV. I've tried everything I know of. When the laptop first starts up, It flashes the red compaq screen, then goes black. Flashes the user login screen, then goes black 2 sec later. When I do the fn+f4, the screen flashes back on, everything looks cool, then 5 seconds later it goes black again. It's not just the light, it goes completely off. (Just on the laptop, external monitor works) I've tried restoring back to factory settings, recovery, and I'm not getting anywhere! I've even tried that black screen fix by Prevx. Oh and I also tried turning the laptop off, holding the power button, etc. It has windows 7. CQ61 I think is the model.

The Compaq laptop with windows 7 starts up with a black screen, as soon as I start it up it will start the cooling fan but the screen does nothing but just a black screen. Before this happend, I was playing minecraft and then left it and when I came back the computer had automaticly locked, I tried to put my password in then it would not let me type, no keys would come up. I then put down the laptop lid then when I lifted it up again and it just was a black screen, I tried to startup again but still black screen.

I am seriously at my limit spent 3 days I still cant figure it out, done probably 100 reboots. Contacted ASUS Support they are useless still in contact with them in troubleshooting this matter.
This is my issue.
When I hit the Power Button my screen goes black, before a bios revision it would just reboot my computer. YES I have set Power Options, Power Button to shut down computer.
I noticed I am missing a Sleep Button Action as its not in my menus. Maybe this could be a leading reason why this is happening? Anyone know how to get this option to show up?
I have used another computer cases front panel and same issue occurs so it cannot be my front panel.
I have a gut feeling the OS ACPI is completely being ignored when it comes to what the Power Button should do, if I set it to Sleep/Hibernate/Shut Down SAME thing still occurs.
I have got the Power Button to work successfully maybe 8 times out of the 100. It actually Logged off, Saved Settings and Turned of Computer as what I am trying to get it to do.
I have reinstalled the ACPI driver from ASUS but nothing changed. Have the latest BIOS Revision as well. I have removed battery and cleared CMOS as well. Also loaded default BIOS settings.
My System:
HAF 922
Phenom II 955
M4A79XTD EVO AM3
G Skill Ripjaws DDR3 1600
750GB WD Black Cavier
1TB Green Cavier
320GB Cavier
Logitech Illuminated Keyboard (Maybe can use ACPI I think dont know if it can conflict?)
Weird thing, guy at ASUS told me to set it to "S1 Only" in BIOS and it actually worked twice, third time I hit the power button it went back to same behavior.
I noticed my chances are higher for it to turn off properly when the power options advanced settings window is open for some reason.
I hope someone knows how to fix this.

I have 2 samsung22 monitors hooked up to a 8800gtx running on windows7 64bit. The problem I've had ever since going to windows7 is 1 monitor works, the other just black screen with power on. I've gone into nvidia control panel and also through windows and it shows both monitors present but I noticed one monitor is attached through an analog cable but both are hooked up with the dvi cables. Could my card have a bad port?
when I plug in monitor 2 in the r/s dvi port it shows the right side desktop portion of the extended view and when I switch to monitor 1 on the right side dvi port it shows the left side desktop view but nothing comes up when attached to the left side dvi port. I've taken a snap shot of my desktop and it shows both screens. I've tried older drivers as far back to 170's and nothing worked.

What can be done with a PC that won't respond when you pressed the power-on button. Looking at back of the PC, the light of the power supply is on, but the power-on light goes out almost instantly after pressing it.

Replaced my VGA cable with and HDMI cable because screen wouldn't leave power save mode due to lack of communication between tower and screen. HDMI solves that. Now I have no internet connection. No signs of life. Cable guy comes over plugs his laptop into the..box thing where the internet comes from... says the internet is working fine must be your computer and he leaves. So now that my screen is working I can trouble shoot - can't find a network adapter. I have no idea what that means, and it is not listed anywhere on my control panel list of drivers and things. Tried to reinstall whatever that is.. which is hard when your just guessing and clicking things. Bottom line is after using the drivers and devices disc and reinstalling everything that said "network" in the title there is still no signs of life. I don't have wireless so the whole adapter thing isn't making sense either.

I don't have the model on me now, but recently I worked on a Compaq Desktop computer. At random times (could be any program open), it would go to a grey screen with weird horizontal lines. I upgraded the video drivers, ran a video stress test and it went over 2 hours with no problems.
The customer just reported to me that it happened again so I am thinking that maybe it is a faulty motherboard (video built onto motherboard). What do you guys think? I didn't wanna give the customer the run around saying "Let's try 1) putting in a new video card then 2) lets try reformatting and lastly 3) lets replace the motherboard)"

I could not get my laptop to start today. I took out the battery to rest it. I can get it to turn on with the battery out when I plug it in but I am stuck on a red screen that has the compaq logo. In the bottom left it says Press the ESC key for Startup Menu. Nothing happens when I press ESC, I am just stuck on this screen.

My wife did something on her PC (she doesn't know exactly for sure what & can't explain it completely me), and now she can't boot up her PC. She says it had something to do with changing the security settings for a program she uses a lot so it wouldn't keep asking her if she wanted to launch it, and that's when it told her to restart the PC, then it wouldn't boot up anymore.When you reboot, the screen eventually goes to a black screen saying "Windows failed to start. A software or hardware error may be the cause" or something to that effect. It offers me the option to "Launch Startup Repair" or "Start Windows Normally".If I Launch Startup Repair, nothing much happens --- it says it's adding files, then it looks like Windows is about to boot up, then it goes to a black screen for a long time & nothing happens.
If I choose Start Windows Normally, it simply reboots & eventually brings me back to the same screen again.I've tried using rebooting and selecting ESC to get to the boot menu, then installing the Win 7 installation disc & selecting the DVD drive, then I select thelanguage, then I click Repair, but it sits there forever with nothing happening.I also tried an outside boot disc I found on the web & it doesn't launch.

i have a Dell Vostro 1520 and im running Windows 7 with a 32bit. It is only 2 years only. It started about a month ago. I was on my laptop viewing and deleting some unwanted photos i had. A few minutes later i realized that i deleted a photo that i wanted. So i went to the recycling bin and restored that photo. When i went back to my photos and went into the album, it said something like i do no have permission to access this folder. Please press continue to get full permission. I clicked continue and i got the access i should have. Now i tried many more random folders and the same thing happened. Also when i came out of the folders, the folders had a big pad lock sign on the front of it. After that i shut down the laptop and went to turn it back on. The laptop will power on like normal. I can press f12 for the boot options. which i have already tried many times. I also tried it in safe mode and what-not, but still nothing. I can hear the fan and stuff spinning up like normal. I have also put and CD into the CD ROM and that spins up fine. So after the Dell logo on the screen, it goes black and stays that way with the cursor. You can move the cursor around no problem. I should also add that the battery light is and has been flashing for a good wile. Its flashing orange and blue. I'm wondering if this has anything to do with the battery. Because my laptop will not charge with the AC adapter in it for many months now. It will only stay powered on with the AC adapter plugged in. One more thing. The LED lights over the buttons. None of the are flashing, besides one, on the far left. And i cant find out anywhere what this LED light stands for.

My son has a Toshiba Satelite P205 that he just upgraded from Windows XP Home Premium to Windows 7 32-bit. After the upgrade completed the computer booted fine. The within 20 minutes he got the BSOD and the system rebooted. Now he can't get Windows to fully start. We've tried all of the options from F8 with no success. We have the Toshiba System Recovery Disk but it won't launch. (The Boot sequence has been changed to boot from CD/DVD and then the Hard Drive.)The Memory Diagnostic from the Windows 7 disk ran fine with no errors. I'm thinking I might need to re-format/wipe the drive to start fresh but don't know where to obtain a boot CD(no floppy drive on this laptop). Does anyone recommend a software that I can purchase to clear everything without destroying the CD/DVD accessibility so I can then use the System Recovery Disk to put it back to the original factory Settings?

My computer has a problem with crashing while playing a video in full screen. When it crashes the screen turns black while the speakers give out a buzzing noise. Everything is unresposive the only solution is to turn it off with the power button. It happens in any full screen video online or offline and even visualizations from windows media player and iTunes, but only in full screen. I don't think it's overheating either because sometimes it takes 30 mins to crash and other times it will crash immediately when put in full screen. *I've tried setting it back to factory settings thus reinstalling windows. *All the directx features are working with no reported problem there.* I don't think it's a memory issue in the computer, as my specs are:
Windows 7 64-bit
Processor: intel core i5 3.20 GHz
Ram: 8 GB
Graphics card: NVIDIA GeForce GT 220
Graphics card memory: 0.5 GB
Any other ideas?

I have an Acer aspire 5732Z. I turn my laptop on and it shows the starting windows screen then just goes to a black screen with a cursor. I tried to do systems restore but it said that I did not have a system restore point. I cannot start in any safe mode. I have all my pictures, uni work etc., and I am terrified I've lost it all. I've only had the laptop a year.

I'm using I have a DELL4500S desktop, on startup it will not go to the login screen, the screen is just black with the cursor showing. I've tried restarting the computer, unplugging everything and restarting it. Nothing is working. When it first starts a pop up shows and says "This Application has failed to start because SAMLIB.dll was not found. Re-installing the application may fix the problem."I'm not sure what it's talking about and what to re install and I can't reinstall whatever it is because I can't get to the start menu.

I just upgraded to Windows 7 on my Toshiba Satellite Special Edition laptop that came with Vista 64bit and the other night i downloaded iTunes 10 and told me to restart my machine so I clicked ok and then my laptop shut off and when it came back on the Toshiba screen came up as usual but seemed to stay on longer than normal then it goes to a black screen with a underscore that blinks for a few moments then becomes solid. Ive tried to use the "F" keys to get different boot options because i have the windows 7 ISO disc and a ubuntu disc that I could use but whatever i try my laptop wont process it just does the same thing over and over again and bever proceeds to the actually boot up windows.

I have a Toshiba laptop running windows 7. It has been running like a well oiled machine since the day I got it.I turned it off to watch TV, then when I turned it back on, the screen shows the Toshiba screen for about 1/4th of a second and then goes black.If I hit F8, F10, or F12 nothing shows up.

I have recently bought a computer and I have found that when I turn it on it runs normally until after the "Resuming Windows" screen, where everything turns off and the screen goes black. It had been running well for the last few days, so this came out of nowhere.I have searched this problem and I come up with a bunch of different solutions but no one agrees. The most common reason (apparently) is my version of Windows 7 Home Premium (x64) and I need to install something or other. But I can't even get to the desktop, and no one really explains it simply.

While attempting to restore a previous backup of my system (with Norton Ghost 15), I got an error, and the system rebooted. Upon reboot, I get the black screen of death with just the cursor instead of the usual login screen. I have tried the following thus far: These all give me the black screen of death with movable cursor:boot in safe mode boot in safe mode with networking boot in safe mode with command prompt last known good configuration I did an initial system startup repair which went through and said it repaired it, rebooted, but no change. I did a pre-boot diagnostic test - nothing memory test - nothing tried restoring from restore point, but it says I don't have any (LIES! BLASPHEMY!) tried restoring from restore point on external disk - seemed okay, then failed. chkdsk - found some stuff, fixed it, no change. tried ctrl+alt+del on black screen of death - nothing
Now, I know that the hard drive itself is alright, that is, the information is still all there still. While I can't give you exact specs, I can tell you that I am on a Dell Studio XPS running Windows 7 home premium 64 bit. I'm at a loss as to what else to do. Despite being a black screen, with just a movable cursor, the system still appears to be running, as every few minutes, it will show the "thinking" cursor, where it shows the little circle next to the arrow.

Recently, my computer starts up windows and after the loading screen it just sits at a black screen forever with a cursor and it doesn't even make it to the log in screen. I have tried safe mode with the same results. What I've Done So FarTried to Repair Startup with Windows DVD Tried to use sfc /scannow at boot (Says pending changes and needs to restart) Tried logging into my Ubuntu partition and virus scanning (None found) Tried copying Reg Files from Regback into config while I was in Linux Tried to Repair Install (But I can't log into Windows ) Tried to bootrec /fixmbr /fixbot /RebuildBcd (Which destroyed my dual boot linux grub, but I was desperate. And still nothing) Interestingly though, after I do /RebuildBcd command it says something like "Found Windows Installations: 0" Tried to System Restore (Gave me an Error, wouldn't you know) At this point I'm not to confident that this can be fixed. If anyone has any ideas I'm willing to try. Or if you have any snazzy suggestions on how I could fix it using another computer, I have a different Windows Pro x64 computer that I can put the HD in if there's someway I can save my data/fix it/repair install from there. I just don't know how.
Edit: I finished the chkdsk and there were no bad sectors, though it did give me a message "Failed to transfer logged messages to the event log with status 50."I did a Windows Defender Offline scan with no viruses and I'm currently scanning with Kaspersky Rescue disk. I don't believe it is a virus, I think it's a corruptregistry at this point. I had just cleaned my registry with CCleaner before the shutdown that led to this >.<

i have an HP Pavillion dv7 with windows7. It is less then 3 months old. Problem- Yesterday the screen went black while i was watching a video, but the sound kept going. so i restarted the computer, and the screen works until you get to the login screen it goes black again. SO i called customer service at hp, and we worked on it for an hour.THe one thing that seems to work is when i go to the device manager, uninstall the display adapters, and restsart in normal mode, then i go and reinstall the ATI device thing in the recovery manager, but everytime after i reinstall the ATI display device thing, it ends up going black a little while later again. lol

I have a Compaq Presario CQ61-420US Laptop, it will be a year old at the end of April 2011. It has Windows 7 Home Premium 64-bit OS. Never had a problem with it till now. I am planning on doing a memory upgrade (currently has 3.0 GB DDR2 PC6400 in 2 slots (1gb + 2gb), ordered a 2.0 GB chip to bring it up to 4.0 GB total memory)Anyway I wanted to make sure I could do the swap myself so I unplugged the power cord, took out the battery, unscrewed the panel on the bottom of the laptop case, found the memory chips, took out both chips very carefully, undoing the tabs holding the chips in, took them out, inspected them, put them back in the way I took them out, making sure the tabs on the chips were lined up, maing sure the contacts were making contact. Put everything back together, ordered the new 2GB memory chip.
Today I went to power up the laptop, battery in and power cord plugged in and everything lit up like normal except the screen never came on, the power button stayed lit, the network status light stayed on, the power indicator was lit, two white lights were flashing at the same time every 5 seconds though, which is abnormal, one at the top right of the keyboard which I believe is the Num-lock light and one on the far left of the keyboard which I believe is the Caps-Lock light. And thats it, nothing ever happens it never turns on (blank screen) even after 20 min's. SO I held the power button down till it powered off. Unplugged the cord, took out the battery, held the power button down for 30 seconds, put the battery back in and tried powering up again, still the same thing.

I'm running Windows 7 Home Premium.As I brought my computer out of sleep mode the computer had crashed with the screen showing vertical, multicolored lines that vaguely resembled gray.I had to hard restart my computer and after the splash screen, the login screen with all the users never appears, nor does my cursor.Nothing is on my screen except a faint glow indicating that it's active.

Whenever the Windows loadscreen passes the screen goes black and I can move a cursor around the screen. I have had this happen before and fixed it with bootrec.exe but I can't seem to get that to work this time. Safe mode has the exact same black screen problem.I have done chkdsk and sfc scannow - Didn't fix it.When I boot into Kaspersky Rescue from a USB drive it mentions that I need to shut down windows properly before continuing. I would like to do this but I can't.I have tried changing the active partition on information in some of these other threads - It didn't seem to work.All disks are healthy according to the DISKPART and Partition Wizard. I have done the HP hardware diagnostic scans and everything comes up fine.
