Default Re: Monitor suddenly went blank. Monitor itself can't be the problem.

I've never used a PSU tester, and I don't have access to one.

Since the plug is scorched, I'm pretty sure the PSU or mobo is fried.

I do have a spare power supply thats never been used, so for now I think I'll try that unless, for some reason, that is a bad idea.

thanks

David I've used a few before and not all power supply testers are created equal.

An example of a less useful tester is here: http://www.amazon.com/Power-Supply-T.../dp/B000EF1JGA

We actually have one of these in the shop. It simply turns on a light for each voltage, but it does not measure fluctuations in a power supply. It won't show whether you're getting a steady voltage or not, just that the PSU is dishing out 12v/5v, etc.

We replaced it with a LCD power supply tester which shows the exact amount of voltage and whether the voltage is jumping up and down.

you could have just tried the onboard graphics on your motherboard. if all is well then, then its your card thats the issue!

thanks for the help!
Scorched? I'd bet real money if you take the motherboard out you'll find a scorch mark in the same place on the back plate. Sounds like you took a strike to me. Did this go out during a thunderstorm?

ive highlighted everytime you said 'mobo' for emphasis on how reptition is a persuasive technique

on topic: im willing to bet that you'll need a new motherboard is the processor sockets are 'scorched'. Slight discoloration could be passable, but if theres some serious burn mark im fairly certain its gone.

i dont think a damaged mobo would damage a PSU, and vice versa.
