I am experiencing a weird problem with my computer. When I turn on my computer, it interferes with my TV downstairs and it won't receive any signal on a handful of channels (ITV, ITV2 and a couple other channels)dunwe. This issue has only happened when I moved my computer into a new computer case, with a new PSU and computer fans. This problem is most noticeable when I am playing any computer game (I can't view any of the selected channels at all), which leads me to believe it's related to perhaps the GPU fan causing interference. Whilst playing, I …

I am trying to connect my laptop to my television by HDMI, i've done it before and it worked. But now I'm having some problems:: When I connect the HDMI cable to my laptop, my laptop's screen goes black, as if it didn't receive any image signal (neither the tv). I disconnect the HDMI cable, and my laptop's screen stays in black, I have to keep pressed the ON/OFF button to turn it off. I've tried to update my drivers, but with no result. Also I have de Uniblue Driver Scanner, but it doesn't detect me any driver update. I …

I have a Microsoft Windows XP Media Center Edition 2005 HP desktop PC when I power the computer on I got Vga input: no input signal and the monitor went back to sleep. If you do you think that is a problem with the video card it is attached to the motherboard. I also don't know that much about computers so please try to keep the answer simple.

In fedora machine, I am handling segv signal, doing some cleanup and then generating core file using SignalHandler(){ // Do Cleanup // For generation of core file signal(a, SIG_DFL); kill(getpid(), a); } But When I run a multi threaded program, the core file seems to point to a place completely unrelated to where the seg fault has occurred. Is there any work around for this?? Say there are 3 thread m (main), t1, t2 if segv happened in t2, I am seeing the core file to point to some unrelated code in m. I think by the time I catch …

Hello everyone, I have a somewhat strange problem with my computer. Yesterday, after I did a simple reboot to change the OS, my monitor suddenly stopped getting signals from my computer. The usual first thought was "that's it, the card is gone". Except for the monitor all other parts of the computer seemed to work fine: I was able to hear the startup sound of the OS. After some searching over the internet, I tried to stop doing cold boots like an idiot, and gave my computer 30 second time for 'freeing it's electrons'. Then.... It worked again! I thought …

Hi, I have recently been building my own computer for the first time, but I have been having some problems with my monitor. When I turn my computer on everything appears to be working, I can control my fans and I can open/close my disk drive. Unfortunately, when I look at my monitor a message appears saying "attention in power save mode press any key on keyboard or move mouse to continue". So next I plugged my mouse and keyboard in but neither would work. I then tried mouse and keyboard on all of my USB 2.0, USB 3.0 and …

CPU fan is turning power supply is obviously working.. I haven't switched monitors yet. When the computer is running I don't hear start up sounds from windows or skype.

Hi. About a year ago, a friend helped build me a new PC using some old PC parts he had. It worked great up until now, though. So today, I leave the computer to grab something to eat from the fridge, but when I come back, I find my monitor display all... scrambled. I guess that's the way to describe it. So I ry to ctrl al del, then alt-tab, and I get nothing. I assumed it was my computer, so turned it off and then back on. However, immediately, my monitor began to display "no signal". I checked the …

Hey Guys! So... I left my PC back home when i went off to college and now that I'm back for summer, it seems that it has missed me because it doesn't work anymore. **First Problem:** When I tried to switch it on, it would start to boot (I'd see the fans try to spring to life) and then it would immediately switch itself off. **What I Tried:** 1. Removed peripherals and reseated all the hardware (RAM sticks, video card, CPU, etc.) -- No luck 2. Reset BIOS to eliminate overclocks. (removed battery) -- No luck 3. Took the motherboard, …

Hello, I am making an application for Android that will save users voice command and then while the application is running; compares the realtime data from the mic input to the one that is saved. So far I have saved the voice in wav file now I want to compare it to the input stream. I have applied FFT using this API as it is compatible with Android: http://code.google.com/p/musicg/ I dont know much about this api either but, I think the FFT data is stored in FrequencyTimeDomainRepresentation object.

Hi guys, still Noob here, so i apologize for not using the correct terminology. I will be as detailed and accurate as possible! I've been using QT Designer, and been trying to figure out how to "combine" the GUI ive created with the python script I wrote before making a GUI. I had my .py script made before I even knew about PyQT, QtGUI, and Qt Designer. My understanding on modules, classes, and objects are weak to say the least, as is my understanding on python also. After visiting [url]http://www.riverbankcomputing.co.uk/software/pyqt/intro[/url] I have a much better understanding of PyQT's modules classes …

Hi there, My computer has been working fine until this morning when it froze shortly after logging into Windows (mouse/keyboard unresponsive and frozen display etc). I switched the computer off and on again, and from this point my monitor has been displaying a 'no signal' message when the machine is powered on. I've tried running it without external/usb devices and the same thing happens. All lights inside and outside the machine are behaving normally as are fans. All cables are in properly (cable into back of monitor was loose but the problem persisted after tightening it). The computer doesnt beep …

Earlier today I downloaded a game recording client from wegame.com and macromedia flash 8. After both were done my computer froze up so i had to reset. Everything seemed fine so i started working on macromedia. In the middle of me working on it the monitor turned black and said that there was no input signal. The computer turns on fine, but there is no input signal for the monitor, and i can't get the keyboard to connect, the number lock and caps lock wont flash or turn on. I'm not sure if it could be a virus from wegame.com …

I think I have a similar problem to an earlier post with my macbook v.10.5.8. I have to be right next to my router for the internet to function. I downloaded iStumbler but as I move away from my router at just 60% signal my internet will cut out and I get the infamous internet can't be reached page. Additionally, this is a new problem, I used to be able to move all about my apartment with no problem. I have another windows computer that works just fine. Often, even when I have the 60% signal strength it says that …

I recently replaced my power supply on a dell 9100 Deminsion. I purchased the 600w one and installed it a day ago. Upon installation, everyting seemed to boot up like normal... fans running hard drive spinning, and what not. (I am not technical at all and for that I am sorry). I had no signal to my monitor, so I replaced the video card yesterday, and I still have no Signal to monitor. The computer runs the same as it did before, fans kicking on and hard drives turning... but still no vid signal. I've tried a number of "heard …

hi everyone, I have a tiny problem with a simple implementation: - i have a main window with a table in my central widget - i want to add stuff in the table gradually, and I allow only the 1st cell (index 0) of each row to be selectable. - on the double click of the cell, i want to pop up a dialog. I've tried connecting the : - itemDoubleClicked (QTableWidgetItem *) - cellDoubleClicked(int,int) - cellClicked(int,int) signals. The slot connected to these signals is a generic function, which will go through the list of objects which are related to …

So I was happily playing Warhammer when the cat walked behind the monitor and *POOF!* no graphics signal. I waited for a while, and then hard-rebooted. Now I get a "Input signal out of range" error. I have:[LIST] [*]fiddled with/replaced the cables [*]swapped the monitor [*]tried to boot in safe mode (didn't work) [*]replaced graphics card [*]had the cat walk backwards behind the monitor [/LIST] Nothing's worked. So, do I get rid of the cat? Can you get my computer back for me? Thanks!

For weeks I've been using the same code without any problems. I call SIGNAL within a thread and it's working like a charm. Then I bring the same module home to the same environment (Ubuntu Jaunty, Python 2.6) and now I'm getting this error: ValueError: signal only works in main thread After encountering this error, I researched the cause and found that you can't have a signal outside of the main thread. But that's precisely what I've been doing all month. The code works like this: In wxpython, I have a progressbar. I call a thread to test if I …
