Resolved question

no signal on monitor after changing power supply

by ryuken3k - 7/30/11 3:27 PM

Moved to a new place some weeks ago and didn't bother reconnecting the my home built computer. Decided to replace my seasonic 550w power supply with a new 750w Antec EA-750 power supply. I then reconnected my Viewsonic VX2025wm monitor and turned on the computer and got the dreaded "no signal" on the monitor.

Not only that, but my GTX 260 graphics card fan is really loud for some reason. I tried a different monitor, a VX2433wm, on the computer and still got no signal on either of the DVI ports on the GTX 260. I connected the VX2025wm monitor on my parents' Dell computer and it worked.

Could the new power supply have damaged my video card? I have no idea whats going on!
