It could very well be a hardware issue with your graphic card.
Things you can try to confirm that option:
1. Boot from a Linux disc or stick (free to make) and go and view Youtube.
2. Replace the graphic card.
I have a new problem which I have searched for on the internet and can’t find a solution.
I consider this the worst scenario and that it is intermittent.
So if I try this that and the other supposed fix I am never going to know if it’s worked successfully.
The only way out of this that I can think of is to somehow run some interrogation software that will identify the problem and then I can work towards a suitable fix.
Right the problem;
I can be working away quite happily then all of a sudden the video just disappears, i.e. if I am playing my music video or just music or watching a documentary on YouTube, they both continue in sound only.
I will tell you what I have done so far;
I have stripped out everything i.e. leads, memory etc. etc. and then re-seated, the only thing that I have not touched is the cpu / heat sink & fan I have left that in situ.
I have undertaken various scans, with various third party sites, and a deep scan in “Safe Mode”.
The only other thing that might or might not be relevant is that when I boot up, along the top left hand side of my “Acer monitor” I get a series of looks like green dots but then after a period of time they disappear and it boots normally, while this is happening it is a black screen not blue.
Something else that may be of value is that my original boot time from switch on to desktop was circa 50 seconds and then ready to start.
This has now progressed circa two minutes and the only thing that I have running in “Services” is as follows;
1. Kaspersky Anti-Virus Service 19.0.0
The other two ticked items in “Services”
• Malwarebytes Service
Both of these are shown as “stopped”
In start up the only thing ticked is “Smart RAM”
On the general tab it is configured to the following;
• Selective start up
• Load system services
• Load start up items
My system details are as follows;
Widows 7 Professional 64 bit Service pack 1
Intel Core 2 Q8300 @ 2.50GHz
8 GB installed RAM
BIOS American Megatrends 0803
Graphics Interface PCI-Express
NVIDIA GeForce GT 430
Memory 1024 Mbytes
In “Device Manager” it shows absolutely no yellow exclamation marks what so ever.
Any comments please would be appreciated.
