Problem - Screen Freeze + Powerfull Noise

[alkaleo]

Hello guys,

Untill a few weeks ago ive starting having problems on my pc getting screen freeze + a powerfull noise in the speakers for a few seconds, no reboot or shut down, and all this in office apps like Photoshop or Browsing not in games.

Last week ive decided to upgrade my rig but ive keeped the following components:
Placa Video - GeForce GTX560 Gigabyte 1GB OC
Power Supply 550W
HDD Seagate Baracuda 250GB

Unfortunately same issue occurred, therefor after a small research ive decided the Video Card is the problem. Sent to Gigabyte Service but after they tested they said it works in perfect condition. After that ive got home ive made some video tests with 3D Mark 2011 and it worked well. Also ive updated the Driver from nVidia. Yesterday the problem occurred again.

Ive also scaned the HDD for errors or viruses.

Could it be the Power Supply or still the Video Card is the problem?
What other tests I could make to see what component fails?

Thanks for your time and Happy Holidays,
Leonard

run hdtune and vendor test tools on the hard drive. for the power supply use programs like open hardware monitor to log your power supply three main rails. see if there not holding. also use microsoft tools and read windows debug/crash files.
