Up until yesterday this was my system:
* Core2Quad Q9550
* P5B-SE motherboard (I think)
* 2x2GB RAM
* Radeon HD 5870
* Tagan TG700-U33 PSU
Whenever I had a really, really high framerate (1000+ Hz in menus for instance) my PC made a high pitched noise, but since it was very rare for me to have that kind of framerate I didn't care.
Yesterday I upgraded my system and replaced the following:
* CPU: Core i5 4670
* RAM: 4x4GB
* Motherboard: MSI B85-G41 PC Mate
* New case with LED lighting and 3 fans
The system starts fine, but when I do anything that strains the GPU in some way (even scrolling in Chrome) the squealing starts (although much more silent).
When I start a game the sequealing is at least twice as loud as it was before the upgrade (even with 30 - 50FPS) and my CPU fan stops spinning and only does 1/5 of a rotation every 5-15 seconds like it tries to start spinning but can't. The game is running perfectly fine though.
What could I try to diagnose the problem? I could buy a new PSU, but I would like to know if I have any free or cheaper options first and I'm not even sure if that would fix the fan issue. Is it possible that 700W or 2x20A isn't enough for a 5870? But why did it work before?
