Monitor not turning on when booting

[DaveU]

Just recently when booting up my PC my monitor started not
turning on automatically. It basically just stays in power save mode
I can get it up and running if I turn on the monitor, let it cycle
then bring it out of sleep with the front panel buttons, and then boot the PC
I use to be able to just flip a switch and the whole system came to life.
PC seems to be acting a bit slow on boot also. Has given me messages about screen resolution (havn't changed anything) and I have had a couple failed start messages (boot to safe mode blah, blah,)
running a 3.2 ghz northwood on an abit IC7G, i gig kingstom hyperx ram (3200)
and an AGP Geforce FX 5900 ultra..
Where should I begin looking?
thanks for the help!!

Bump....

any suggestions here?
I'm leaning towards the video card...
A good AGP replacement solution?

Thanks!

My thoughts are leaning towards the video card as well. But have you tried to reinstall the drivers for it? Maybe something corrupted them?

I've been PCIe for the last year, so I can't recommend any AGP cards for ya.

First thing I'd do is take the vid card out and then put it back in to make sure it's in tight. While you're in there check the motherboard for any swollen or leaky capaciters (battery looking things on MB - should be flat on top, not rounded)
Drivers wouldn't have any effect until after Windows loads... but they could be the cause of the resolution errors once in Windows.
Could also make a memtest bootdisk and run that. My mom's PC over the weekend actually had a bad vid card and a bad stick of memory and part of the symptoms were the same as yours. Until I fixed them both the screen would not come out of power save.

thanks for the input ....

btw, I did install the newest vid card drivers thinking the same thing
that maybe somehow they got corrupted, but no dice...
Not sure how to pinpoint this, so I guess I'm going to
bite the bullet and purchase a new vid card first.... Thanks again!

What power supply are you using?

 

[DaveU]

Power Supply is an Enermax
EG465AX-VE(W)
I pretty sure its a darn good power supply
was when I bought it 3 years ago or so...
Its possible it could be the power supply?
PC Seems to run fine once I get the monitor to
Power up. Sometimes I have to reboot the PC
twice before the Monitor comes up.
PC will boot up and win start sounds off, but no image.
I have to make sure the Monitors out of power save
for it to catch too.
