[solved] No video signal on cold boot - replug power and all fine

Hi,
My issue is a cold boot one. 6 weeks ago I installed a new mobo with new CPU. Three weeks ago I installed new RAM. Spec follows.
Now, since yesterday, when cold booting the system after some time off, the fans start spinning but that's about it. No video signal. Keyboard dead (numlock off), nothing. Simple solution is to then unplug and replug the power cord and press boot again, which then starts the system normally.
I googled this post at techspot, which labels my problem straight-on but they are running ASUS mobos. Since my system worked fault-free before, I am critical to their solution. https://www.techspot.com/vb/all/windows/t-7148-No-signal-to-monitor-amp-no-post-beeps.html
Any ideas what to do? Thanks a lot for your replies!
MoBo: MSI Neo2-FR, BIOS: 1.9
CPU: E8300 (C2D 2,83 Ghz)
RAM: 2*2Gb Corsair XMS2 800
GFX: Sapphire HD 3870 Silent
PSU: Seasonic/ARCTIC, active PFC
       3.3V: 28A, 5V: 30A, 12V:17A
       -5V: 0.5A, -12V: 0.8A, 5Vs: 2A
       450 Watt max. / 350 Watt continuous Power
(The PSU is quite weak, I know, but has always worked just fine before, might be it?)

but how come the problems came all the sudden
Well, they usually do, doesn't matter what component.
Try another Power Supply and see what happens. Than you will know if it is the PSU or not. (Maybe you have another system you can use the PSU from or a friend can borrow you his power supply unit.)

[solved]No video output in Skype with nvidia driver - vesa works fine!

Hi,
I'm struggling to get Skype video working. The webcam works perfectly - the other side can see me. But I can see neither myself nor my opponent - the corresponding place in the Skype window just gets white. It doesn't matter whether Compiz is active or not. I can also see myself when using cheese, video output also works properly.
Now, I supposed that it's an issue with my graphics driver (the proprietary nvidia driver) and changed it to vesa in the xorg.conf. Well, I have a resolution of 800x600 now, but the video in Skype is working perfectly! I will go ahead and try an older version of the nvidia driver but maybe it's a known issue and there is a workaround?
Thanks,
PhotonX
edit: Same problem on the 173 driver version.

Why the video playback stotter but audio is ok and all system resources are ok as well?

Hi,
I'm using Premiere Elements 12 and prepared a project using m2ts files of my sony camera. When I started the project, everything was find, editing easy. Now, some months later I wanted to finish the project on the same laptop ( Intel Cor i5-4200 2,50GHz, 8GB RAM, 64 bit Windwos 8.1, 1TB Hybrid HDD, dual graphic: Intel HD Graphics 4600 and NVIDIA GeForce GT740M). The system resources are not completly used during the playback, maybe 10 - 15% usage, RAM is between 20 and 50% usage, harddrive usage is between 10 and 40% usage. Video data are stored local on the harddrive (not on USB or network).
When I open the original files in e.g. VLC or Media Player the playback is perfect, no interupts. The playback of rendered elements in Premiere Elements is without interupts as well. Only "native", untouched HD material stotters after a short time I'm working on the project. It's the same for other videos, when I start a new project. It's anoying me because it was the reason why I decided for the SW.
I deinstalled Premiere Elements completly, used also CCleaner to remove unused registry entries... reinstalled it completly after some restarts... updated to 12.1.0.0 but after an afternoon of installation, the same issue is back.
Who can help me to fix it? Thanks for your feedback.

Player version 7.1.6 is a very old version but it should play H264 / AAC videos without issue.

BIOS – 1.1 updated to 1.5, default settings (I'm not overclocking)
Windows XP SP2 OEM
I installed the above system last summer and have been having problems ever since. Initially the video signal dropped after booting so I replaced the graphics card. This didn’t work so I replaced the MOBO. All was OK for a while then the system started crashing for no apparent reason but would usually be OK for a while after re-booting. Then it failed to boot into Windows at all. I checked the BIOS and noticed that the Smart Fan setting in the H/W Monitor had disabled itself somehow (I had set it to be enabled with a target temperature of 40OC). I re-enabled the setting and was able to boot into Windows OK. However it still crashes every time from a cold boot (the CPU fan comes on full speed for a few seconds then the computer just shuts down). After a few re-boots it settles down and seems to be fine.
I’m assuming the problem is something to do with CPU temperature but in the BIOS H/W monitor the system and CPU temperatures are never above 30 to 35OC. As the system seems to be perfectly stable once it’s been re-booted a few times it doesn’t seem that the CPU is actually overheating. I’ve tried setting the CPU target temperature higher (say to 60 OC) but still get the same cold boot crash. Note that the MSI Dual Core Centre utility in Windows shows the same CPU and system temperatures as the BIOS monitor (although the GPU temperature is much higher at 60 OC).
Any suggestions for solving this would be much appreciated.

I'm not familiar with your brand of ps. Have you tested the rails while the system is running using a digital voltage meter?

Help - Changed BIOS settings, now no video signal

Please help -- I changed my BIOS settings to "High Performance Defaults" and configured my boot sequence, etc. Now I get no video signal when I boot.
Thanks,
-RE

I presume you mean you can't get back into bios by holding down DEL. quickest way is to reset the JBAT1 jumper. /take power lead from PSU, remove JBAT1 from pins 1 & 2, put jumper on pins 2 c& 3 for 5 secs, then pur it back on pins 1 & 2, put power lead back in, Boot, this will reset bios to defaults, you will need to enter setup at prompts and set your boot sequence etc. Did you have turbo on as well as high performance? Better using Safe defaults, then using core center to see what you can set it up to.

N9800GT-T2D512-OCv2 no video signal

Dell 8400, 3.6ghz P4, 1GB, PCIE
My old card is a Geforce 6800GT, and I have the lastest drivers installed for that. It works fine.
When I install the new 9800GT, there is no video signal (black screen). The system post is fine (all 4 lights on).
I have a vga plug&play monitor so I am using the supplied digital to vga adaptor. I have tried both card outputs and there is no signal on either one.
I can't install the new drivers without a working display.
Is the card bad or is there some compatibility issue?
If my HW is somehow not compatible, is there some utility I could use to check?

You are not understanding me. Get GPUz and tell me what speed you PCIe lane is running. Even at 8x when the 3D demands are high, such as folding@home or Crisis or some really intensive game set at the highest settings you can, the GPU is likely going to need the same power in a PCIe 8x slot as PCIe16x slot. If the fastest PCIe slot you have is 4x, you've waisted your money. I missed that you were using a Dell--often Dell PSUs are underrated(they can deliver more than what's printed, although this tendancy shouldn't be relied upon). You may be stressing the PSU to it's limits which will shorten it's lifespan--your choice.

DUAL BOOT windows 7 and linux HELP with Current info on BIOS, MBR vs GPT, etc

I have a feeling this should be easier than what I'm making it. Please educate me on Lenovo's BIOS Setup menus, etc.
I have installed easyBCD in Windows 7, and plan to use it to set up my new boot menu with Linux Mint (and possibly other distros).
I am using a live DVD. I inserted the DVD and went into SETUP and selected to boot off the DVD drive. It started to boot into Linux and all was going well.
However, I realized that I had not checked on the Secure features (Secure Boot, EFI). So I shutdown again and went into BIOS. I went to the SECURITY menu and Disabled UEFI. Then I disabled Secure boot.
Tried to boot off the DVD and couldn't get anywhere. Kept putting me back into the window to select the boot device over and over again. THought I'd ruined my machine
Anyway, finally stumbled upon STARTUP menu, and put it into EFI Legacy, and I was able to get back into Windows 7.
Obviously before I pursue this further, I need some educaiton on your MENUS, Lenovo and EFI/Secure Boot.
I have a feeling that I can probably now install the Linux but want to make sure my settings are correct before I pursue.
Thanks, Kim
Moderator note: this thread gets more Linux-flavored with each post Moved from the "T" board to the Linux board.

Hi, thanks for ans. Your specs are almost identical to my T530 ,which I should have listed. The only diff is
I have an i7 35something processor. Same intel card, RAM and HDD, not that that should matter I'm guessing.
I purposely avoided the Nvidia card because of all the heaadaches with Nvidia.
I have to teach a class tomorrow and I need to clean up my notes. (Definitely not computer related...LOL.) I don't want to be stressed out about this during class, so I plan to wait to attempt a new install tomorrow afternoon.
What I have done is find out some more info about dual booting with windows 7. I went in to windows 7 to shrink the C: partiition and it said I'd have to reserve at least 220 GB for MS! Not what I wanted; I don't really care a thing for MS. I was born and raised on Unix and Linux; I never really fiddled with MS after the demise of MS-DOS during my college days.
Given that, and the fact that I'd lose half my 500 GB HDD to the Borg, I may just chuck the entire dual boot thing and just load Linux on it.
If you say you're running Linux on it just fine, that would be a great encouragement. No HW problems at all? Everything working fine? Which distro are you using?
I plan to test Mint, Fedora, PCLinuxOS, Mageira (sp?), saybahon (sp again?), Debian Wheezy, and even Pear, LOL. I'll keep trying till I find a distro to run on my Lenovo T530, but I'm guessing all of 'em should do okay.
I have Lubuntu I could give a spin, as well and Crunchbang and Bodhi, but they're all 32 bit. (I have an antique Dell desktop that I still use down in my woman cave.)

Syncing dual boot data: SL and Mavericks?

Hello Happy New Year to Us All!
I am wondering what to do to best keep user data between SL and Mavericks synced? I have an old Macbook Pro with Snow Leopard and I want to dual boot SL and Mavericks. My computer is an 8 gb RAM mid '09 15" Macbookk Pro w/ new 256 gb SSD and w/ original 500gb HD now in optical bay.
I've partitioned the SSD in 2 equal size volumes, one for each OS boot. SL is now running on one of the partitions, and I could make a third partition on the SSD for one possible shared data volume. (I know the SSD needs to keep adequate free space). The HD is ready for one or more data volumes, backup volumes etc. (I also have several external drives.)
So I have read that you can store your Home Directory in any folder on any volume you want using Advanced Options in the Admin account in Accounts.
Can my Snow Leopard boot volume and the Mavericks boot volume share the same Home directory or somehow same user data on one data volume? I assumed the answer is no and that the data is packaged differently b/w SL and Mavericks but a lifehacker article made me wonder: http://lifehacker.com/5702815/the-complete-guide-to-sharing-your-data-across-mul tiple-operating-systems.
Also Level 9 Baltwo seems to have a lot of experience with this.
https://discussions.apple.com/thread/5481468?tstart=0
https://discussions.apple.com/message/15728093#15728093
https://discussions.apple.com/message/17052849#17052849
But his posts on these threads indicate that he now uses separate data volumes. I wonder is that one for each of his separate OS boot volumes, and if so, why? Snyc advantages?
If this is the way to go, back to the main question: how to best sync the user data between SL and Mavericks?
--Simply figuring out which files to move by hand or get Carbon Copy Cloner to move? Learning to use Dropbox?
--SL workarounds for iCloud?
--Soho Organizer or Fruxx?
--a Snow Leopard Server?
--convert a user account to a network user account?
--other?
Thank you and I hope Baltwo and other will help me.
Stu

However, data can be shared if kept on a third data volume.
Hi Baltwo, thank you. Is sharing user data on a third volume an effective way to keep SL generated data and Mavericks generated data consistent and usable by both? If only one OS is running at a time and therefore the shared data is only used by one OS at a time each change, any change, would seem to be saved sequentially. What are the pitfalls and risks doing it this way? Especially since,
Apple constantly changes how updated versions retain stuff in their libraries.
You, on the other hand, keep separate data volumes, one for each OS boot volume I think, I presume in order to keep OS boot volumes lean and all able to fit on a SSD?
I could do it this way too and spend most of my time in SL b/c it seems faster than Mavericks on my system. (I installed Mavericks last night and set up iCloud for first time). I could just use Mavericks when necessary, and manually sync Apple Mail like you described, Chrome bookmarks, and other things.
PS I thought there were a lot of things Mavericks would open up for me, like Airplay and Find My Phone w/ iCloud, but the former still won't work on my system and the latter works in SL, now that iCloud is set up.

Loading Boot Camp failed and now it tells me to repartition my main HD

I had an issue running Boot camp and now it tells me to repartition my HD down to one partition. I just ran Time Machine to back up my computer to an external HD. My question is, if I repartition the main HD on my Mac Mini, can I restore my Mini back to what it looks like today, but with the correct Partition so that I may run boot camp again and all of my data and programs will still be there? I am afraid to lose all of my pics and programs if I do this repartition...

[Solved] A75A-G35 gives no video signal over HDMI, resolution over DVI limited

Hello community,
following problem: I have been using my A75A-G35 board with an A4-3400 Llano APU, the APU has been connected to a 19" BenQ FP91GP monitor via a DVI cable. I got its maximum resolution of 1280x1024 with no issues.
Now I have purchased a 24" Dell U2415 monitor with a maximum resolution of 1920x1200 and wanted to connect it to my computer. However, I got stuck:
1. I get no signal whatsoever using the HDMI output and a HDMI>HDMI cable. I have tested a different computer and connected it to the Dell with the same cable successfully, so the cable and the monitor should be fine.
edit: Disregard the following as the problem with the DVI cable appears also with the other computer. The problem is therefore just the fact that the HDMI output of the board doesn't work!
2. I get a signal with a DVI>DVI cable + DVI>HDMI adapter. I can access the BIOS, the boot manager and see the boot screen, however once the desktop should be displayed the screens turns black and the monitor keeps switching to standby and back on again, the screen staying black all the time, however. But before installing the driver package (for chipset and video, downloaded from the MSI website), I could see the desktop with a resolution of 800x600. Also, if I boot into safe mode, I can see the desktop and increase the resolution up to 1280x1024. Higher resolutions up to 1600x1200 are available, however selecting any of them results in severe screen flickering.
3. If I boot my Linux install, I have almost the same behaviour. I see the boot messages but then the screen turns black when the desktop should appear. However, if I connect the old BenQ monitor to the VGA port, I get a signal on both screens, however both screens have the resolution 1280x1024 and I cannot increase the resolution of the Dell, because if I try to, the screen turns black again. Lower resolutions than 1280x1024 are possible, though. Note that the "second monitor trick" does only work with Linux, with Windows I get only a black screen on both monitors.
As a side note, the DVI cable I'm using is a DVI-D single link, so the maximum resolution it supports is actually exactly the resolution of the Dell, 1920x1200.
Thanks for any hint,
Photon

your welcome!
when you said your problem and the symptoms I thought that board sounded familiar as alot of people when it first came out that we had to explain that to them so I had a look and yes it had the jumpers to switch ports for its digital display display signal to be routed to another port so i thought that was the cause!
have fun with your board now you have it in HDMI mode!

Monitor no longer recieves video signal [Solved... w/ Fire.]

Greetings and thanks in advance for reading. I'm thinking the problem is either Video or Processor but second opinions are always appreciated:
The problem started about a week ago when I was playing Wizardry 8 via Cedega (OpenGL accelerated Game.) The screen mysteriously went black, the monitor turned to low power mode and the sound looped once or twice before just going dead altogether -- yet the computer was still on. I rebooted and things worked again.
2 days ago the game thing happend while playing Unreal Tournament 2004. Montior went black, sound looped once or twice from the past few seconds, then power stayed on but there was no video signal. I tried rebooting this time only to find nothing happening and it's still doing nothing since. The power turns on, no beeps or anything occur and it goes thru the same familiar clicks when checking the hard drives and CD Rom. (The spinning still occurs as well, the keyboard blinks once and I can turn on / off the numlock. The fans turn on inside the case, and the network adapter is recieving a current.)
I tried taking out the RAM, unplugging the hard drives and such systematicallyh only to have it do the same thing. It boots up, doesn't beep, doesn't proceed and the monitor remains blank. I tried swapping the monitors with no avail. I even cleared the BIOS via popping the battery and waiting a bit (yes it was unplugged) The only thing that produced a notable difference was when I unplugged the video card and powered it up without one. It beeped once long, waited, beeped again long, waited, and kept doing this ad infinitum. I should also mention the red LED indicating that the HD is being accessed is constantly on but there is no HD activity discinerable to the human ear.
My hard ware is a Gigabyte 64 Bit AMD Board (Tryton K8 I believe), GF6 6600 GT, PCIE Model 1 gig of RAM and the rest are minute details but I'll include them upon request.
I've had this machine little under a year now (actually 2 weeks from now it'l be ja year) I haven't swapped out the video or processor since I do not have a spare one to replace it with to test it, neither do any of my friends.
Any further questions or such, let me know. Thanks in advance again.
(Meant PCIE, not EIDE, sorry for the confusion)

Something similar happened to a friend of mine. His laptop (under windows) bsoded twice while playing cube. the second time, it didnt boot up again, and refused to power on, there was no sound from the hard drive, the laptop didnt boot at all.
It turned out he had busted up ram... *shrug* it's hard to say though, such symptoms could highlight a lot of things.
Make sure all the connectors in your case are fine, everything's plugged in, and if you can, test out the ram in another compy

Laptop will boot... backlight turns on... but no video signal

Hello!
(I searched but couldn't find a situation quite like mine, so sorry if this is a repost.)
After dropping my iBook, I busted the bezel/clutch. The unit powered up, including a fully functional display, but the lid just opened a little screwy.
So, I had the bezel/clutch replaced by an IT buddy, and when everything was reassembled, the unit would still boot up, the backlight would turn on, but there was no video signal! We thought maybe the VGA cable got messed up in the process, so we had it swapped out. Same problem.
Any ideas? Any thoughts if this problem is related to: http://discussions.apple.com/thread.jspa?threadID=877652&tstart=60 ?
I got a heck of a deal on this thing, so I'm thinking about just connecting to an ext. display, backing up everything, and parting it out on eBay. But this was my first Mac, and I only had it for a week, so if there's an easy/economical fix, I definitely want to give it a go!
Thanks folks!

Lactoes,
This is from Apple:
"Display
No display, or dim display, but computer appears to operate correctly
1. Remove any connected peripherals.
2. Try known-good power outlet, power adapter and power cord.
3. Press F2 (with the fn key pressed and not pressed) to increase the screen brightness
setting.
4. Reboot the computer—hold down the Control and Command keys and press the
Power button, or press and hold the Power button for 5 to 10 seconds to shut down the
computer, then press the Power button to restart.
5. Reset the power manager by pressing the key combination Control-Option-Shiftpower.
Warning: Make sure you do not hold down the "fn" key when resetting the
power manager.
Warning: Resetting the power manager means you will also need to reset the
date and time (using the Date & Time control panel).
6. Reset PRAM (Press the power button, then hold down the Option-Command-P-R
keys until you hear the startup chime at least one additional time after the initial
startup chime).
7. Verify backlight cable and LVDS cable connections are seated properly and that the
cables are not damaged (refer to display assembly replacement instructions).
8. Replace display.
9. Verify cable connections and check cables around the hinges for damage.
10. Replace logic board."
The LVDS cable:
922-6368
922-6432 (SS)
Check this out:
http://www.pbparts.com/shop.php/9226432
apparantly there were two versions of this cable the first and the ss.
Even so you should get something. Try the external monitor and report back.

Who Said What That Got The "Cold Boot Problems Solved" Thread Deleted?

Hello, guys.
I logged in this morning and saw that Falipay??? had posted last in the thread I started called [something like] "Cold Boot Issues Solved And Temps Now Correct".

P6N Sli Plat. weird cold boot issue (solved)

Hello again,
Since a few days I'm having troubles starting pc in coold boot
If i shut it down and leave it for a couple of hours, cold boot, it wont start, but when I shutdown and power down psu for a minute, it will boot
If I then turn the psu back off and on and leave the pc off, the next morning it starts normally.
Tried on stock settings, no problem, checked psu out, functions normally, none to less fluctuations on all lines.
Set my first disk to boot only, disabled the rest.
Had this running for 5 months without hickups, but since i wanted to go to 3.6GHz and installation of my new SATA-II, I've had this problem.
What am I missing.
Tried lowering NB, which results in unstable system, looser timings mem, lower/higher Vdimm, no effect.
System is in IDE not raid since my second is IDE, for storage.
I connected the 8 pin cpu connector instead of the normal 4 and that didnt work either.
Changed slots for the DIMM's, ran memtest at 860MHz 4-4-4-15-2T, no errors after 10 hrs.
Orthos/Prime95 stable after both 10+ hrs, blend and small fft's.
Hope it's not the mobo dying, checked it out and cant see anything funny, or smell strange things.
And as said at stock no problemo.
What did I do wrong this time
Edit:
After oc-ing to 3.6GHz benched cpu and it ran at Tcores max ~61C.
When i returned to old settings for 3.44GHz, I set everything back the same way it was, even cleared cmos before doing so.
Tcores max after 10 hrs of Orthos or Prime95 ~55C @3.44GHz

yeah well if I set the timing to like 5-5-5-15 or something I'm sure it'll work fine. But that's not the point... Cuz if I have to set my timings to 5-5-5-15 just to get it up to the 889mhz that I need it. I might as well just run the run in async mode at 4-4-4-12 800mhz.
Seriously I have the weirdest ram. I can run it at 4-4-4-12 800mhz with like 2.0 volts. So There's like 0.2 volts of overclocking there. But it just won't work at 889mhz. And it not like it doesn't pass memtest or orthos. The weird part is that it passes both at 889mhz at 4-4-4-12 timings at 889mhz. The problem is that it won't start cold boot. I'll have to press the power button and then press the reset button to get it to boot. I guess that's not a really big problem, but having to press that reset button each time I cold boot is just really annoying.
If I set them to 4-4-4-12 at 800mhz, the computer turns on fine.
I think the problem is the precharge for the ram. I'll bet loosening the timing will make it work, but I just don't want to loosen those timings...
I just bought new ram so we'll see if that solved my problems. :-P
It might be the electron migration thing though. I hear electron migration damage to things show up as random unpredictable problems.
I would say my problems are random and unpredictable.
By the way, I just got a couple of fans for the ran slots. They're sort of just jammed in there. Kind of not elegant really. But I now have TEN fans in the computer. I hope that helps my ram overclocking.

Z77 Mpower - No video signal on boot - Debug code "Ad"

Hi, I can't get any video signal from my mobo, it seems that it can't boot at all.
I just plugged CPU (i7 3770k), CPU cooler (Noctua NH-D14) and 1 RAM (8gb DDR3 2400MHz), no vga, hd or dvd writer, then I obviously plugged the 24 pin connector from the PSU and the 8 pin connector for additional CPU power.
I have my monitor directly plugged to motherboard but when I turn on my pc, even if fans are working and motherboard leds are on, I still don't have any video signal and on the motherboard I can see the debug code "Ad".
Please can you explain what is happening?
Thank you very much for any advice and sorry for my bad english.

I tried to reseating the CPU and nothing changed, then I reset the CMOS, waited for a couple of minutes, restored the power, and the debug code became "A0", but after about another minute I retried to turn on the PC and the Debug code returned "Ad".
I'm quite frustrated.
Side Note: For my try I didn't use the boxed cpu cooler, I just installed my cooler without plugging the fan cable to the "CPU fan" pins, i thought it was sufficient to see if my motherboard boots, isn't it?
Update: I tried ro reset bios again and plug change the RAM stick in solt2 with the other one. Again the system was unable to boot but the debug code became B4. After a couple of minutes I tried to boot again without touching anything and the debug code returned "Ad", I can't give an explanation to these apparently random debug codes
Update 2:Now I switched ram slot, from slot 2 I mounted ram stick to slot 4 and reset cmos again. The first boot after resetting gave me debug code "64" then again, shout down, wait a couple of minutes, turn on Pc and... debug code "Ad" again.
It seems that first boot after cmos reset the mobo gives me a random debug code, then it returns "Ad" as always for the following boots.

[solved] No video signal on cold boot - replug power and all fine
