As the subject states, my computer freezes while playing games, and only while playing games. Am I right in thinking it's the graphics card?
Some more information:
- Semi-new motherboard + processor, known good (from my SO's computer, he upgraded and passed me the old ones)
- Old power supply (known good, from my old system)
- Brand new RAM (my old sticks didn't fit with the new motherboard, SO still needed his
- Brand new graphics card
The computer freezes only when playing 3D games. Which game doesn't matter (World of Warcraft, Dragon Age, Mass Effect, etc etc). Neither do the game settings - tried dragging everything down to minimum, but it'll still freeze (and to be honest, even if it did stop the freezes - I bought a card capable of playing these games at max settings, I damn well want to play them at max settings).
The freezes are very random - I can go for an entire day without seeing one, then get two in very quick succession.
The inside of the computer is free of dust and all the fans work fine.
I left a memory/CPU stress test (this one
) running for 12+ hours without any errors.
To me, all this seems to point to the graphics card as the source of the issue - but I'd like to be certain, since sending the graphics card back to the place I bought it from will leave me computerless for a couple of weeks while they test it and decide whether to send me back a replacement or the original one... and I'd rather not be out the shipping money plus the computerless time if it turns out it's not the graphics card after all.
