Windows 7 Home Premium 64bit

2011 HP dv6t laptop

i7-2820QM processor

4 gigs of RAM

Radeon HD 6770m graphics

 

 

Starting yesterday, my screen will occasionally go black for variable amounts of time. Typically it will go black for one second, then back to normal for two or three, then black for about ten seconds, then back to normal for a while. However the screen isn't just black, there is also a little bit of RGB fuzz/noise on the left side of the screen. Typically it has occurred when just browsing with chrome or browsing the steam store, so it seems like it couldn't be anything being overworked...

 

Is this just some setting that's overloading, or is my graphics card starting to die, or is it some visible symptom of malware, or something completely different?

 

Thanks in advance

wreck9967,

 

Yeah it sounds like a video card issue. The solder connecting the gpu to the motherboard may not have a good connection. If the lapop at one point got hot enough it could cause some of those solder joints to go bad. i.e. if you are using a blanket and have the laptop on top of it. The blanket covers the vents and you do not notice. The laptop will get really hot.

 I had something similar happen in my older mac book pro. I reflowed the solder on my motherboard and that fixed the issue. If the a fan is not working or works some of the time that could cause it to overheat. Without a fan it can overheat very easily.

Hello ! You could check for heating problems with a program like SpeedFan. You also could hook up a another monitor;like your TV, to make sure it's not your laptop monitor.

Heating shouldn't be an issue, my computer is always on a desk surface, sometimes even propped up as a slight angle for more airflow. I will try speedfan though to check.

 

Since I posted the issue, I've determined that it occurs mostly when browsing the internet, and occasionally when watching a movie in VLC. I'll see what SpeedFan finds out.

 

 

Edit:

 

Well bleep. I'm taking a guess that if SpeedFan displays a little flame symbol by your components, it isn't exactly a good thing. I'm reading around 56degC plus or minus two for everything except the hard drive (because it's a hybrid). Any ideas besides never ever using it on a soft surface?

Hello! I'm reading the same thing, and I don't think I'm over heating. Here's a link where you care compare CPU temps.http://www.computerhope.com/issues/ch000687.htm

You can (generally) check the maximum operating temperature range for your CPU directly...by using Google and using "your specific  processor, cpu-world" as the search string.

 

Example:  This system has an FX 8320 cpu, my search string is "FX 8320, cpu-world".  This brings me to a summary page for that CPU and the temperature range data can be scrolled to by anyone.

Ok well I'm seeing that an i7 2820qm has a max temp of 100degC, so I guess that knocks out heating issues.

 

Could it be a physical connection to the screen has started to get worn out? It's been three years so I don't see how a faulty connection to the GPU would have just now arisen...
