recently I've bought a new Radeon HD 6570 video card from ebay, I put it in my pc, and it has worked for a month. Then all of a sudden one day my monitor shut down and my fans went to full RPM, and I had to force shut my pc.
I used a different card, and the machine works fine. Every time when I put this new card in, the pc works for maybe 15 minutes to one hour and same thing happens. Drivers were up to date, my power suppy is good (450w) , my processor is intel celeron dual core e3200 2.4Gh, so the processor isn't taking too much power so that the gpu can't run.
Only problem was that I had to use the vga/dvi adapter, my monitor is vga and gpu has only 2 ports, dvi-i and that other dvi, I can't remember, but I've put the adapter on dvi-i because it wouldn't work on the other one. Could this cause trouble, and it there a way to see some error message or something on why my PC shuts down...
