PC crashing from video files after boot up.

[Thori_]

This is a strange issue and has troubled me for some time now. Here is the process just before the crash.

1) Boot up everything runs normally no errors no issues. ( at this point I can browse the web or play steam games)

2) I'll load up a steam game for example on one boot and have no issues at all.

3) But If I am browsing the Internet and watch a video whether it be youtube or a small advertisement window on a web page my PC will make a tick noise and completely freeze up. requiring me to reboot.

Now heres the weird part. If I leave my PC on for say 2 hours after booting up there is no problems at all and I can watch videos to my hearts desire. It only happens shortly after a reboot or from me restarting after a crash.

Things that cause a crash so far
Youtube
Any video player
Small Ads in webpages.

But at the same time I can play Elderscrolls maxed out with no issues whatsoever

Some specs
Intel i7 4770k
8GB DDR3
MSI Z87-G45
GeForce GTX 660
1863GB Seagate
1863GB Western Digital
223GB SanDisk SSD

This only started happening after I installed windows 8, Everything is updated and if its not it has been before with the same issue.

Assuming you have installed all your motherbds win8 drivers; have you updated the bios?
