Hi,
in the last week i had issues (hardcrashes) with my computer like described in this thread (http://www.tomshardware.co.uk/answers/id-1735622/random-crashes-randomly-colored-screen-computer-unresponsive.html) while playing StarCraft2.
I tried to fix these by cleaning the fans, increasing the fanspeed, memtesting and reducing the clockrate on my graphicscard.
Sadly today the pc crashed again but this time i got a blackscreen at booting with no POST beep. So i started breadboarding until i realized that i got an onboard card on my mainboard and tested it. The computer ran perfect. To test it i put the card back in with the same result: computer runs but I got no POST beeps.
So my assumption is that I got a defective PSU which can't supply my computer when the graphics card is connected. Sadly I'm a poor student with a tight budget with no spare PSU or graphics card to test this.
My question is if my logic sounds plausible and I need with high probability a new PSU or could the error still be at another part of my hardware?
Thanks for any help I can get
