when i watch a youtube video or a TED talks i am forever in danger of it hanging up / stalling. Sometimes it is fine, more times is hangs there and makes a strange repetitive sound like a computer bleating and the picture stalls. On occasion it gets out of it, but more times than not, I have to shut down the computer. Help.
Some very common measures to check and end this:
Use CCleaner to clean junk.
Clean booting the PC.
Using MalwareBytes and other antivirus to check for viruses.
Using MemTest to check for defective RAM.-most likely your case.
