Blue screen with weird vertical stripes.

[Malcolmekkk]

Hi all,
I´m having troubles with my new PC. My computer crashes randomly to blue screen with weird vertical stripes, the sound is working for a while and then I have to reboot it. This is happening regardless on CPU and memory usage, my computer does not have to be overloaded or something. This is happening mostly when I watch videos on youtube or when I´m using flash apps. Sometimes everything goes OK without crashing for 20 hours, sometimes I got this crash for about every 2 hours and sometimes even more frequently, like for every 5 minutes.
I´v allready tried my graphic adapter on my mate´s PC and seemed to be OK. I´v changed my motherboard, I´v tried to change my RAM for another, I´v run memtest on it and seemed to be fine.
I guess this problem is not CPU related.
Might this be caused by my power supply unit (Corsair pcx600W)?
I´m very hopeless about this, I´v tried some drivers updating, some benchmarks and nothing helped. Temperatures are OK.Reinstall OS doesn't help.

I have this setup:
AMD Phenom II X4 970
AMD Phenom II X4 970
Kingston HyperX XMP T1 8GB 1600Mhz
Sapphire Radeon HD 6870 1GB DDR5
Samsung SpinPoint F3 3.5" 500GB
Windows 7 64bit Ultimate

I will be happy to see your advices on this,
many thanks in advance.

Hi, I have experience similar problem like yours. It will happen in few min or in hours. Make sure your pc hang only when you watch video or any video related apps. Then it maybe faulty video card.

Check your graphic card again in another pc and run video apps. In my case, i replace my video card. My video card was faulty made similar issue like yours.

This isnt about cpu or psu. Also check video card power connector if it is ok.
