When you turn on a PC with a video card, the PSU goes into protection. Everything is fine without her. The question is how to fix the vidyuhu (if it is)?

Question

Iron

Vidyuha gtx550ti (with additional power).
The question is how to test what is the problem?
I have a multimeter.

Answer 1

Set the power supply to normal.

Answer 2

Either the power is overkill (the PSU does not draw out) or the power is short) Take the manual, count the power, this board eats 116 (count 150W). If not, do a "dialing" through the power circuit.

Answer 3

The power supply is not enough. More powerful ones will work fine.

Answer 4

The video card is old - most likely the capacities are swollen. On his own, the same, soldered after 2-3 years of operation. Look for swollen capacitors and resolder. The issue price is 50 rubles.
