I put in a PCX 5750 (Old Card made in 2004) for her to play Sims 2, but getting alot of pixel related errors every so often and its only running at stock speeds. (Reboot twice whilst she was playing)
I've seen people using 8600GTs and 4670s on this type of PSU.
So I need help...
Question 1: Is it likely that the PSU cant handle the card? Or is the card likely to be faulty?
Question 2: Would my components draw too much power that I shouldn't have a graphics card in it?
Question 3: Assuming my PSU is fine, what would be some recommendations for 2nd hand cards (3xxx, 4xxx ATI series or 7xxx, 8xxx Nvidia series).
That PSU is pretty weak, even when it was new. With only 19 amps on the 12 volt rail, it is most likely your problem. There are plenty of 350-400W units selling for around $35-$40. If the extra cost isn't an issue. Look for a 12v rail with at least 25 amps for that set-up.
I've been following this post all day, and I have to say that my hat's off to ya lazy_mofo!
You've got an older system back in use. Play with the graphics settings a bit more, and it may get stable for you.
