Hello everybody. I have a Sega CD Model 2 and a Genesis II and they are having this weird problem and I've been trying really hard to find out what it is. So, basically, there is this humming coming from the speakers whenever the system is on, and also this image distortion/flickering.
I am using a 10V 1A DC adaptor for the Genesis, and a 9V 2A adaptor for the Sega CD. (Both generic). I should also clarify that neither the Genesis nor the Sega CD have the internal metal shields and I'm also not using the mounting plate (I didn't get it when I bought them).
I've been trying different combinations of things in order to find a pattern but I couldn't , so I'm just going to type down everything I did and what came out of it.

Using the Genesis ALONE unattached to the Sega CD: Clear audio , clear video (at least most of times, very rarely the video would also look a little flickery)

Genesis + Sega CD, both plugged, playing a SCD game: Humming and video "interference"(?) (Horizontal bars moving vertically really fast). EXCEPT sometimes! I don't know why but sometimes it works just fine!

Genesis + Sega CD, both plugged, playing a Genesis game: Same as above.

Genesis + Sega CD, only Genesis plugged: Very loud humming and significant image distortion.

I also noticed that the humming is very quiet during the TMSS screen or any other blank/black screen.

It's so frustrating not knowing where to look! I am trying to sell these consoles which is why I'm so interested in fixing them.
If anyone knows what it might be, I'd be SO grateful.
My attempts to fix the problems: cleaning the cartridge slot with a toothbrush dipped in rubbing alcohol and cleaning the expansion port with acetone.

I probably could have given more details about this or explained it better, so if something isn't clear enough, just ask.

Hi everyone!
Lately I've been having weird problems with my laptop. After some time of booting it up and using it normally, it will start to get really hot. And I found out that this process on Windows called "Interrupts" is taking up all the cpu of one of the core, that in total takes up 25% of the CPU.
So I started researching to find out what exactly could be causing it, and used LatencyMon to pinpoint the problem. This is the output I got:

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates. 
LatencyMon has been analyzing your system for  0:00:39  (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs):   9956,788632
Average measured interrupt to process latency (µs):   7,734608

Highest measured interrupt to DPC latency (µs):       351,079001
Average measured interrupt to DPC latency (µs):       5,093296


_________________________________________________________________________________________________________
MEASURED SMI, IPI AND CPU STALLS
_________________________________________________________________________________________________________
The SMI, IPI and CPU stalls value represents the highest measured interval that a CPU did not respond while having its maskable interrupts disabled.

Highest measured SMI or CPU stall (µs)                7,697225


_________________________________________________________________________________________________________

 REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count:                 msmpeng.exe

Total number of hard pagefaults                       283
Hard pagefault count of hardest hit process:          247
Highest hard pagefault resolution time (µs):          2003431,340852
Total time spent in hard pagefaults (%):              9,442092

At first I tried disabling the battery controller and that used to work (or probably it didn't but I thought it did) but that is just not doing the trick anymore. Same with the wireless card, whose drivers I updated to the latest version. Now the really funny thing, is that there is also a process doing the same on Linux, the "kworker" process, I didn't do much research being on Linux though. So this made me think that the problem itself is not software related as I first thought.. could this be the case or just mere coincidence? Oh and I even tried updating the BIOS which also didn't work.
This has been driving me nuts for the last months. I seriously don't know what to do anymore and it's really annoying because when it does that, I can even hear audio glitches and the cooling fans are really loud and it's all just plain annoying. So yeah thats it. I would thank you guys so much if you could help me figure this one out.

Hey guys, I hope you can help me out with this one, it's extremely frustrating because it not only crashes, but makes (I think) others program crash when using the "Open File" UI( More specifically, Autodesk Maya 2012).
So basically, everything was going alright until one day I decided it was time to clean a little my install. I installed CCleaner and run it. After that Google Chrome wouldn't work anymore, I reinstalled it and it was working again.

But then explorer.exe started to crash repeatedly. I can't reproduce the crash by doing something in particular, sometimes I am just browsing a folder full of TGA's and it crashes. Sometimes I press F5 while being on the desktop and it crashes. Sometimes just browsing random folders for a while will make it sooner or later crash.
First I thought there was something wrong with QuickTime, but after uninstalling it, it still crashes. So I decided I would re-install the OS. For that I would use the Recovery Partition that I got when I got this computer (an ASUS K53S).

I booted the partition, a "loading Windows" screen showed up, and then it showed an empty desktop. After some seconds of absolutely nothing, the computer resets itself. I don't know if something like this is covered by the warranty.

So, what do you guys think I could do about it? I don't have any Windows 7 install disc to do a clean install. (And I am not going to buy one)

Hey. So basically I'm in Germany right now, and I've been craving for a new phone. So I thought a Sony Ericcson Xperia X10 Mini Pro will do. (It's not incredibly awesome, but it has wi-fi, I'm happy with that).
I plan to buy it without SIM-lock for obvious reason, but I wanted to know if there is some other factor that might make me go mad when I come back to Argentina with such cellphone.

It'd be great to take it home :B

I have to make a DVD that has to be played in Germany and I need to know whether DVDs in Germany are NTSC or PAL, also which Region corresponds to Germany. According to wikipedia, Germany uses the PAL standard, but I want to make sure because so does Argentina(supposedly, I guess), but we actually use NTSC on DVDs. So yeah, to know that would be of great help.
