graphics card issue

hello i seem to be having a problem with my graphics card and/or motherboard.

every time i unplug the computer from the monitor to hook up somewhere else, it's 15-30 minutes of turmoil. the monitor will just not pick up the signal. i have to turn off the computer, try replugging it in a different dvi slot, turn it on again and hope for the best. after a few times of doing that it eventually picks up. random success rate every time. it's quite frustrating.

i have the EVGA E-GeForce 8600GT on Asus P5K EGA775.

i have tried, 1) making sure all the plugs are in right, 2) getting rid of dust inside, 3) different monitors and different vga to dvi converters

btw, there is a pattern that might help the diagnosis. whenever i hear the motherboard beep when i push 'power', i know that the monitor will turn on. when it does not beep then the monitor will not pick up the signal. i have come to find out that this is the POST beep, but i'm not sure how to utilize that information to fix my problem.

anyway, thanks for your help in advance. looking forward to learning a lot here on this forum.
 
then its not a grafic's card problem, but its a motherboard problem. :)

When the motherboard doesnt beep after you pressed the power button, it means that the motherboard isnt POST-ing have you overclocked your pc by any chanse?

either way, let me put it this way, the motehrboard tells the grafic's card to start up when the motehrboard sees that the power button is beeing pressed. when the motherboard doesnt start up tough, it cant tell the grafic's card to startup, hence the screen stays black.

edit:
Try resetting the bios. (now that I think about it, it might jsut be a bad BIOS battery... as long as the pc is connected to the mains, its fine, but when you disconnected it, and then try to start it up, it acts weird. if you have a volt meter, try and measure the voltage of that battery. (you have to pul it out to measure it. :) )

thank you so much for your help! what you're saying makes complete sense.

i'm not a computer expert or anything but i do recognize the beep as POSTing. and no, being a computer noob that i am aware of, but have not, overclocked my pc

i do not have a volt meter or access to one, but i can try buying a new battery to replace the old one and see if that fixes it, right?
 
you could try. (but I'm not a fan of buying stuff, and then see if it helps, because if it doesnt, I wasted money.. oh well, thats beeing dutch for you I gues :o )

Either way, yes, buying a new battery could help. but like said, its not guaranteed to do so. but, the fact that the pc boots at least some of the time, at least to me, is an indication nothing is broken. :) (Like said, I dont think somethings broken, I could however be wrong with that. altough, i hope i'm not ofc. )
 
Dont think its the battery, you could try, they are just like 3 bucks. Most of the time with a dead battery, from a cold start it will just reset everything in the bios back to default/including the clock.

When it doesnt boot, does the fans spin up or is it just dead in the water?

hmm, he thought it was the grafic's card, so I assume the pc sounded like it wanted to start up normally (appart from the beep) so I gues the fan's started running.
any idea what else it could be? (I mean, when it only does this from a cold start, but not when the pc is constantly plugged into the wall, its gotta be something beeing drained, I think... at least, cant think of any other explanation at the moment. )

apart from the POST beep, case fans and cpu fans definitely run. hmm...thinking about it while i'm typing this post, i was always sure but never actually checked to see if my graphics card fan was running.

i can see logically how a battery switch might help, but honestly i haven't had this motherboard for that long so i'm hesitant to even spend $2 to switch the batteries out

Seems like if its the video card and the board is fine, then you should be getting a bios video error beep tone. I dont know, hate to say its the motherboard. There is a slight possibilty that it could be the P/S going out. Just losing it on a cold boot. Do you or know anyone with a P/S you could just try. Having extra parts to swap out really helps. Buying something and it doesnt work is a bummer.

by p/s, do you mean the power supply unit? if so...well that's a bummer. i'm only moderately confident of putting a computer together...and i don't quite have a psu near me to try switching it out.

but everything you guys are saying makes sense. another bit of info that might help with the diagnosis: when this problem started happening i thought i had a bad video card so i upgraded from a GeForce FX5200. i got the same problem, but when i plugged it in a second video card slot on the motherboard it seemed to have fixed it for a while, so i thought it was just that one bad slot. eventually the problem resurfaced, and it's been bugging me ever since

thanks for all your help guys. this forum rocks
 
Yeah that kinda kills the video card probability. Other than just changing the battery, to take a cheap wack at it. I would say 50/50 its either the motherboard or P/S (Power Supply) making a slow march to death.
