Im using an HDMI cable i'm guessing thats the problem but I'm afraid to go back and try to fix anything. I also noticed a red LED go off as soon as i hit the power button but it never lights up again. (Only once) I think its my motherboard. Also, i tried turning it on about times and the last time i turned it on, my fans connected to the motherboard were no longer turning on. Im afraid i might've burned my motherboard. Here are my specs:

The other times I started to run it, it doesn't display any BIOS or anything, and it doesnt seem like anything is runnin except the fans and lights.I got it into safe mode initially at one point, but again, the signal to the monitor cut out and I have no idea what happened after that.Each time I power-button-ed it off.Things were running fine until recently; I did install AirDisplay (forgot there was no wifi - I'm used to my laptop which does).I think it is expected, but I tried to put in the recovery CD to boot from CD, but, of course, nothing displayed.
View 3 Replies View RelatedI just upgraded my AMD catalyst software to 12.4 on my HTPC. Been noticing that when I am viewing via my Sharp 19"LED TV I get signal cut out after about 20 minutes. I notice this when my screen save comes on in WMC. It eventually craps out and I get "no signal" messages on my screen. It comes back if I simply click on the mouse.This never used to happen before. I could leave the HTPC on over night and simply turn the TV monitor off. When I would turn the monitor on in the morning, the Desktop would be visible.Are there new settings in 12.4 that could be causing signal cut out (i.e. like an energy saver option)?
View 4 Replies View RelatedI am experiencing a very disturbing issue with my newly installed ATI 4870 and my Windows 7 RC (7100). Prior to installing this card I had the following setup, which worked flawlessly.
nvidia 8800gt
intel p35 chipset in the motherboard
Samsung a656 40" LCD connected via a DVI to vga connector.
When I got my 4870, I uninstalled the nvidia drivers,rebooted, installed the latest (9.5) ati drivers and rebooted.
Then, I got a no signal in the monitor at the windows login screen.
Mind you, that when I (dual) boot in Vista, using the 9.4 drivers, everything is fine.
Things that I tried:
1. Creating a new monitor.inf file (located at the windows folder) using info from a post in this forum.- This should not make a difference, since I was using the same monitor.inf file in the same windows 7 installation, whitout any issues before I installed the 4870.
2. Changing the ATI .inf file to include only one resolution for the r7x cards 19 20 10 80 00 00 00 60- I think it sould be a refresh rate issue, since the vga port of the TV supports many resolutions, including 1600x1200 etc.
- It could also be an unsupported resolution, if the ATi driver cannot detect the monitor correctly.
3. Installing the windows 7 default ATI driver.
Things that I noticed:
1. I can login only in safe mode.
2. Low res mode (640x480) gets me to the login in screen, but as soon as I input my passowrd, I get no signal.
3. Changing DVI ports in the 4870 (it has 2)
Does anyone have any ideas?
This morning I was on facebook, playing games, and the computer crashed. A blue screen popped up and gave an error but was gone before I could read anything. I have replaced the video card and the power supply

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
View 9 Replies View RelatedI bought a new CPU and Motherboard today and put them together. I'm assuming I plugged the wires properly. So far no beeps when i start the computer but the fans are working and the LED lights light up. The monitor says "power saving" everytime I start it up. I have windows 7 32 bit installed on my hard drive and was planning to format it into windows 7 64 bit but I can't when my computer won't even start.
View 34 Replies View RelatedStarting today my computer has been randomly turning itself off, although running lights are still on, and the computer sounds as if it is still running normally.Essentially what happens is that it crashes out, the monitor says input signal lost and then nothing happens. First two times it crashed whilst using Photoshop. Third time I installed a program to monitor the HDD temp. It was running just over 40c when it crashed again (had a low end game running to see if the HDD temp would rise). I waited 30 min before turning the computer on each time.Opened the case to check for any build up of dust, it seemed fine.I have also checked that all the cables are plugged in correctly.Also definitely something wrong, because holding down the power button didn't turn it off. Had to turn the computer off by the switch at the back of the computer.Only thing new with the comp today was updating Microsoft.Net framework, a few hours before the first time it crashed.

[Code]....
Got a PC with Nvidia GeForce 6150 graphics card with no overclocking. Sometimes the monitor loses signal and does not work. Sometimes it works just fine. I've tried different VGA cable and different monitor, situation didn't change. I've got 4 different connectors.
- 1 VGA and DVI on Nvidia
- 1 VGA and DVI built in into motherboard.
Sometimes, when the Nvidia doesn't work, I connect to built-in card and monitor starts working. Next time when it's out, I connect back to Nvidia. There have been situations when only one of the four connectors is working. This means that on one graphics card there may be only one connector which is functioning. I don't get this. Problem isn't in the display nor the cable. It also doesn't seem to be in the graphics card as the built-in connectors aren't fully functional neither.
My problem is that if I connect the computer via DVI to a display it functions normally, but when I hook it up via HDMI to my Flat screen, it doesn't show the splash screen that gives you the option to enter bios. The screen just stays black until the windows welcome screen(win 7 64bit) comes up, then it acts totaly normal from that point. When I try to press the del key during the boot, I believe it is entering the bios, but the screen remains black so I can't see anything. I am guessing that the MB is not sending the signal to the Flat Screen until it loads windows, but can't find out anywhere that confirms that or what to do in order to resolve it.

So it's not the monitor or the cable( switched them a few times by now) I believe it is the new tower. I think it might be the VGA card but know little about these things. Manual says it is a Intel Graphics Media Accelerator (Intel GMA 3100).Or could it be something else? By the way I have Windows XP if that makes a difference.

(My first PCIExpress card - be gentle ;-) Here's what I've been doing
for what seems like the best part of two days -
1 Boot in safe mode, disable 8500. Reboot.
2 Drivesweeper'd nVidia display drivers in safe mode. Reboot.
3 Restart in safe mode to verify drivers gone, but 7 just goes ahead
and renistalls 195.62 anyway (A moderator on the nVidia boards says
that these latest drivers should NOT be installed in safe mode.) & asks
for a reboot.
4 Reboot as instructed, then screen blanks after entering password;
pretty much what I've gotten from day 1.
> Now, just today I tried something I saw somewhere here (?) where
A I reboot the PC (after 1,2,3 above) with my monitor OFF
B Enter my password 'blind'
C I finally get to a proper desktop which appears to be using the
correct drivers (Refresh rate looks much better) but I can't verify
graphics card changes, as this causes a blank screen again.
Monitor is the only device plugged into the GF card.
Where have I screwed up?
I turn on the computer, goes past the bios screen as normal, does the windows loading screen as normal, then the screen goes black and the "No Signal" message is displayed.
Now, here is why it is different. I type in my password and press enter, without being able to see and wait for the logon sound to play, then if I unplug monitors cable, I hear the noise of windows telling me a device has been disconnected, I plug it back in again the device connection noise then plays and low and behold, there is the desktop.
I have been running Windows 7 build 7100 for roughly about three weeks until this started happening about one week ago.

Also, I have noticed too after logging, randomly Aero will disable itself, I have to open the 'Personalize' option and run the troubleshoot to get it to fix itself again.
I assume this is the correct section, as I am experiencing visual issues. Apologies if this is not the correct section.
I encountered a new issue with my PC and I sincerely don't know what to do. In fact, after a while, the monitor is showing no signal. I changed the video card with a brand new one and still my PC will do the same. Is there a worm or software issue or the motherboard miss-fires?
View 3 Replies View RelatedWhen I start my computer with drivers installed my monitor loses the signal when I should be receiving a log in screen. I can boot up fine in safemode and/or if I'm using Standard VGA Graphics Adapter. To my knowledge I do not have an onboard graphics card as there is nothing to plug an avi or vga cord into aside from my graphics card. I should also mention I tried using an NVIDIA GeForce 8500 GT and experienced the same problem.
View 5 Replies View RelatedAnyone come across this? I have a brand new pc, its nice and fast, installed Windows 7 a month ago and the ATI drivers that were available then.
Now with the lastest update for ATI, my monitor loses signal midway through the install of the new pack and I have to restart my pc to do anything.
I have tried different versions of the drivers, uninstalled my previous drivers and tried to install fresh but no dice.
Any ideas?
I have used the search feature but it seems like others are having different problems with the 6200 than I am.
Whenever I install either the Default Windows 7 found driver or the Nvidia 195.62 Driver for my 6200 video card my system boots up, shows the Windows 7 startup screen and then the screen goes black like I had unplugged the monitor, the only way I can get video back in normal mode is to go into Safe Mode and disable the Video Card.
I've seen that it might be a refresh rate issue, but it won't let me change the refresh rate, the only option I have is "Use Hardware Default Setting"

View 4 Replies View Relatedi just recently built a new gaming rig and am running an SSD for boot up.
Everything turns out just fine except when after the windows logo appears, I can hear a little crackle noise from my headphone then the monitor loses signal and my g15 keyboard LCD turns off, then a few moments later my monitor and keyboard comes back to normal and i am a the login screen. It is not a big deal but am just puzzled at why it would do this.
It does slow down my boot speed by a lot especially for an SSD. Anyone know how i can speed this up? Someone told me disable USB 3.0 to speed things up. Any problems with Asrock MOBO drivers that could affect this?
My monitor is an HP S2031. The computer is a Compac Presario CQ5814 PC, Processor is an AMD Dual Core Processor E-350. Running Windows 7 Home Premium 64 Bit. Bought in 2011. Running Chrome Browser most of the time. Shockwave crashes on me quite often but seems to "fix" itself. This had happened shortly before the monitor turned red. I had turned off the computer and when it was turned back on the screen was red. I restarted it a couple of times and it finally returned to normal.
View 1 Replies View RelatedI have two monitors on my system (win 7) and from time to time the main monitor gets turned down in brightness. The other monitor is just find but something ( a virus, malware or program) is turning the brightness down for no reason. I have run malware and virus protection and found nothing.. Sometime is will be in the middle of a session and other times it will be on boot. It's not the monitor I'm sure (turning it on and off does not work) and it's always the same monitor that is effected.
