Loss Of Video Signal On Startup?
Dec 27, 2012
So I just finished up installing new RAM, a new CPU Cooler, and a new GPU Cooler... My computer booted right up no issues, until it lost video signal right after I saw my password screen. My computer was still on, and (to the touch) nothing was overheating... So I rebooted, same issue..
I then booted in Safe Mode, which booted right up. I backed up all my files and whatnot onto a secondary HDD and proceeded to reinstall Windows 7, thinking that would fix the issue, and I was sadly wrong.
I then booted back into Safe Mode, in which my computer ran fine, reinstalled all the drivers, and proceeded to restart my comp. The same thing happened, lost video signal right when my password screen showed up.
I am all out of options here, honestly. I thought it was because I normally use two monitors but only boot on one now, but that wasn't it. removed the new RAM and that didn't work, thought my comp was trying to run off an On-board card, but that wasn't it(computer only recognizing my GTX 550).

For almost 3 months now I have had an issue of when I choose to reboot my pc it will lose video signal and the only way to reboot my pc is to shutdown and power it back on for the video to pop on as it should it started with my ATI 5970 but since then I have upgraded to a ATI 6990 but it has the same issue. What would cause my video to lose signal on a normal reboot so I don't have to shut down when a reboot is needed? Major changes before this started was I went from a 750w psu to a 1000w psu.

I have new Acer Aspire 5739G laptop and fresh Windows 7 on it.
The wireless card is Intel WiFi Link 5100.
The problem is that wireless works only in short distance with access point - max distance is about 5 meters.
In that distance everything works fine.
But if I go farther or to another room it disconnects.
With other laptops all works fine even on very large distance.
I tried such things (nothing helped):
* uninstall, reinstall or update drivers
* install newest drivers from Acer site
* install newest drivers from Intel site
* tested with xp & vista drivers
* on network connection properties unchecked all things except tcp/ip v4 protocol (microsoft networking,sharing, link layer topology,QoS, TCP/IP v6 ..)
* disabled homegroup
* on adapter properties changed signal frequencies (1,6,11),
* on adapter properties changed standard type to work with: 802.11 b or g
* on adapter properties changed signal to MAX, don't use power saving
* disabled Internet security, firewall
* Changed access point signal broadcasting with no encryption or wpa
* it disconnects from another access point the same way (problem with system not wifi AP)
Maybe something forgot to say, but there was few hours of testing and can't fix it .

I have a brand new custom built computer. I assumed that I could take a cloned drive of my old computer and install it in my new one. Well, I took the hard drive from my new computer and installed it in an external drive case and cloned to this drive using Acronis clone tool. Then I installed the cloned drive back in my new computer. Now no signal whatsoever to the monitor. My monitor is good as I tried my old computer with it and it works fine. I hope I haven't done major to my new computer

I just built a new gaming rig with 8gigs of RAM. I made the mistake of installing WinXP Pro x32 on it. I find out that 32 bit OS's can't access 8 gigs of RAM, so I went and bought an OEM Win7 64 bit disk. Come to find out now, Win7 x64 doesn't play well with many HDTV's. Something about they changed the instruction in Win7 to not allow for overriding something called the EDID signal from the HDTV. So now I'm screwed again. Now I got 8gigs of RAM but no video. Great. What now?
I need to go and buy a third OS that will work this time? WinXP Pro x64? Yeah, it's not the video card, the video card drivers, or the TV. It all worked just fine with WinXP Pro x32 installed. And all the cables are plugged in tightly. Win7 x64 will output video signal to a generic VGA monitor. If I set the resolution to like 1024 x 768 or something then swap the VGA cable from the VGA monitor to the HDTV I get video signal. As soon as I reboot, no video signal. I get video for the post screen and the Win7 startup screen.
As soon as it trys to boot into the desktop, no video signal. My AKAI TV only says "Not Support". Win7 will not get past the HDTV EDID handshake. Win7 sucks. Now I find myself looking at the Windows web site HDTV "compatibility list" for Win7. Like trying to work my life around bill gates and his crappy software. Serving Windows instead of it serving me. When will those people ever get it right again after WinXP? Any workaround that will make Win7 override the HDTV EDID handshake?

I had a power loss while running on battery (it still showed power left, but suddenly shut down anyway) and when I restart, it reports that the Windows is not activated and Window is not genuine and system might be a victim of "counterfeiting."
Is this a virus (I have MSE on continuously and about once a week scan with Malwarebytes)? I have run 'sfc /scannow' with filtered output ('findstr /c: "[SR]" c:.....logsCBSCBS.log" and it appears as usual.
How can I lose my Windows activation?

I just bought a Netgear WNA3100 wireless usb adapter for my HP Win 7 64 bit laptop. I have been trying for 2 and half days to figure out why my speed is slow, why i don't have a good signal, and/ or if I do have a bit of a signal to my luck, why my signal comes and goes. I don't have internet at home at the moment because I am trying to save up to go to school. I am picking up a public business signal from a block away (which I have asked for permission to use), but I only am receiving not much of a signal with the Netgear usb wireless adapter.

Everything on my computer was fine this morning when I left for week, but upon my return I noticed that my keyboard/mouse wasn't working. I restarted my computer and confirmed that my keyboard works in the bios and whatnot, but when I get to the windows login screen, I get no response from the keyboard or mouse.the mouse is a simple USB one, and I'm using a PS/2 keyboard, so I doubt it's some sort of sudden driver issue.I tried logging into safemode, and I get the same result, can't move my mouse or use my keyboard.Does anyone have any idea how to possibly fix this issue? I'm unable to restore from an earlier state either.

Ok well i got a new Dell Studio 435 Tower in april or so i7 920, 6gb 1066 tri-channel, 1gb ATI 4870, 750GB WD Black Caviar... i was running x64 Vista Home Premium and it was smooth as butter... had a 5.9 WEI and was pretty happy with performance.
2 nights ago i saw that the Windows 7 RTM was available on MSDN so i snagged x64 Windows 7 Home Premium... upgraded in place fine but now its much slower than my x64 was!
It takes longer to both boot up and shut down, some programs freeze when opening or closing them... i re took the WEI and it went down to 5.5. For some reason all my other scores shot up to 7.5 except my Ram which fell to 5.5 and my HDD which fell to 5.9 ???
I started investigating and it now says that i have 6GB installed and 1.99GB usable. What? When i was using Vista it said nearly all of it was usable.
I went into my bios... updated it to the newest version along with the intel chipset... in bios it states that i have 2048 available out of 2048 installed??? I have combed my bios and don't see ANYTHING that will let me mess with ram period.
I did the whole start>run>msconfig>boot>max ram, but no matter what i do it always defaults back to 2048 when i reboot my machine and go back to it.

This has been an issue since I upgraded to 7201. It isn't constant, and seems to be worse when I'm downloading large files, especially multiple files from one source (like an album in iTunes). It is fixed by release/renew (or just letting Diagnostics do that).
If I'm not using a lot of data (regular web browsing, working on a database online, etc), it seems perfectly fine. It is holding so far downloading one track at a time on iTunes, but if I do 2, it drops the connection.
I'm using the Home network config, router is working normally, and I can't recall this happening before 7201. I've reset the router, upgraded firmware, and it only happens on this PC. I've set WINS, tried all settings for TCP/IP 4 and 6, and using the other ethernet port on my motherboard.
More of an annoyance, really, but I can't figure it out and it is bugging the hell out of me.
EDIT: I can still get 1 mb/s on a single download, but trying 2, I get 600/400 for about 10-15 seconds until it disconnects.

I have been researching the topic and am at a loss after around an hour of fruitless research. I recently upgraded from xp 32 bit to windows 7 32 bit. I want to upgrade to 64 bit so theres more RAM available and cannot find any information on doing it without discs that doesnt use USB or something. Got an external hard drive what the hell do I do? I downloaded the files but then couldn't open of course bc they were 64 bit files or whatnot.
(my cpu is capable of running it)

For the past year or so I've been using a telstra broadband manager USB to connect to the internet, now all of a sudden I am getting no internet access, not just from the broadband manager but from other networks aswell. I have tried my phones hotspot, other USB's and WiFi's to none of them working.It would start up and work for about 15 seconds, and then internet access would just cut out completely. I have AVG Internet Security 2012 installed and I have tried disabling the firewall (Windows firewall also) and yet it still doesn't work.

I use a Macbook for my personal use usually, but when I turned on my PC after not using it for a couple of months, all of my user information is gone: Documents, music, everything. The only thing is I don't think it's gone, I can't access my music using iTunes on that machine, but I can access it using Windows media player. If I try to open OneNote pages, I get nothing. I have run Spybot and AVG antivirus. It seems as though my user account information is being hidden. Other user accounts (my wife's and a guest account) are working just fine. I would prefer not to return to a restor point, as I don't even know when this was lost.

just came over from XP Pro...had to get a 64-Bit machine; & went w/ an ASUS running Win7 Home...which I upgraded to Pro.I began to lose my internet connectivity, intermittently & noticed that, when it happened, the Network icon in the task bar showed TWO networks...(???).one labeled 'Network - No Internet Access'& the other labeled: 'Unidentified Network - No Internet Access'.Sometimes the problem would go away if i rebooted, but eventually it became a permanent dilemna.Verizon checked my modem...said it was fine, but sent me a new one anyway. Same problem continued. Took the PC back to Best But & swapped it for a new one...& it's been fine 'till this evening. It denied me access once.I rebooted; & got it back. Obviously, something is amis w/ Win 7 Pro in the way the network connection is set up.can't be two modems or two computers.I noticed it seems to happen right around the time that the OS goes looking for windows updates not in the same category.

Whenever I type a certain command into the Command Prompt (I'm not sure if it's only admin-only commands only, probably is...), I get an error saying the command is not recognised? I was trying to flush my DNS and renew my IP using IPConfig when it happened. Then, I decided to test another command "sfc /scannow", that didn't work either (note: CMD was running with Admin privileges too). I could perform these commands fine before. And I'm on an administrator account too.

any time a program, ANY program (doesn't matter if it is an installer or what) is not programmed to open or run in the background, if something happens in it, the focus gets stolen from where I am (say Firefox or a Microsoft Word Document), even if the application doesn't actually pop up, then I have to re-click on the program to regain focus and continue working.The real problem is when things pop up unexpectedly as I am typing and I hit the space bar, which results in my accepting something I may not have wanted to.Is there any way at all to FORCE a global "stay in the background" for any program that doesn't have focus or to prevent programs from stealing the focus?I tried the mouse hover trick, but that's an annoyance because if I accidentally bump it off of my active window, whatever one it comes on top of becomes active and is only worth it if I'm working in a full screen window (which is maybe 30% of the time).I am running Windows 7 Home Premium x64.

As of late I am experiencing a strange loss of Bios setting when I either warm boot or cold boot. Examples as follows: When restarting either from a warm restart or cold restart, I will hear 3 beeps which I believe is a memory related error, correct me if I am wrong. I do know if settings go back to default range the voltage is less than what is needed to successfully boot with OC settings enabled.I have also noticed that I sometimes do loose all of the bios settings under many different conditions, regardless of how and why I had to restart.The one setting that stands out the most is the FSB setting, many times this value is the only value changed; [goes back to default] and needs to be reset.This machine has given me yeoman service since 2008 and has been OC'D at a 50% overclock 60% of the time, the rest of the time it is OC'D at a bit higher rate and stable.I did replace the Battery on the MOBO[P5K-Premium WiFi/AP thinking this might possibly be the cause. I have found the incident of this happening to be less but values in the BIOS still change however infrequently.

On these occasions, while watching Hulu on my HTPC, which only connects via WiFi on my Router (Cisco E3000), the movies were interrupted by a loss of connection, indicated by the white tray icon turning orange, and when expanding it's menu, the connection bearing the name of my network had disappeared.On the first failure, the flashing light on the network adapter (Belkin F5D8055) continued flashing as usual, but the steady light was out, until pressing the connection button. The second time around, both light remained lit as normal, but in both instances my network connection on the network adapter's tray icon had disappeared. Using the WiFi's network adapter's connection button, and the router's PBC button didn't solve the problem, nor anything else that I tried.Since the WiFI connection is primarily for internet access, rather than connecting computers, and that shutting off my desktop doesn't usually effect the HTPC's internet connection, it seems obvious that the connection is managed by just the router, adapter and HTPC, so I fail to understand the relationship between the vanishing network and the loss of internet connection.When these failures occurred, they only lasted for ~ 10-15 minutes, and then were restored on their own, with no more apparent reason than the outage had. So far, this is only an annoyance, but I fear that it is an omen of greater problems on the horizon, and I have no idea of how to isolate the origin of the problem..
