Hello, today after I took out my old keyboard and put my new keyboard in, for some odd reason, I cant see anything on my monitor. As in,no display what so ever.

The computer starts up normally, The fans is spinning, hardrive spinning, but no display...

I even put the old keyboard back and even tried without keyboard, still no display on my monitor.

I tried the monitor on other computer and it works fine.

My mohterboard is a Biostar sckt478 P4m80-m4 with a Celeron 2.6, along with one stick of 512 ram.

The video is on board, however, I did try a PCI video card and no display....

are you getting any beeps, a completely blank screen is usually a monitor, gfx card or psu problem, just because fans spin doesnt mean psu is ok

 

[brite750]

also when you tried pci card did you go into bios and change from ob to pci? no you didnt because you couldnt see anything, so that exersise may have been meaningless, also you did actually plug monitor into the pci card i hope, seen that before also

 

[martint]

I tried different PSU's and it's not a PSU problem.
as for the second one.

I put in PCI card, plugged in it and tried and nope.

I hope the power was off (and not just the case switch) when you changed keyboards. Try resetting CMOS with the MB jumper although I really won't think that a keyboard change would mess that up.

 

[martint]

Hmm, well it wasnt.
I always had changed keyboards when the power was on..

Did the cmos thing
removed battery, waited....and nope.
also did the cmos jumper thing..

well, you know what this means, you may have to pull this puppy apart, down to psu/mb/cpu/1 stick ram and work from there
since you tried psu, you'll have to look at the other 3

Try starting in safe mode

has no image on the monitor

What color is the monitor button when the computer is on but no image is appearing?

 

[Rich-M]

I know this will sound weird but it happened to me one time. Try another monitor on the pc. I had it happen where an older monitor stopped working completely on one pc and still worked on others...it baffled me for days and I never figured out the reason.

has no image on the monitor

Happened to me once and was because monitor settings were somehow changed to setting that computer wouldn't support. My screen was blank. My friends told me I needed a new monitor. Started in safe mode, set and saved default settings, monitor started to work again.

Well there is a difference in the two issues you speak of.
1. no monitor display
2. monitor goes blank after boot screen.

number 1. you would not see a boot screen therefore you are not able to see anything at all. period.
number 2. is as you describe.

I could see nothing either, no boot mode no nothing. But I could see my keyboard and the F8 button even after hitting the power button. Hit power, wait a sec, start tapping F8.

then what?

 

[RootbeaR]

then what?

Then it booted up in safe mode, screen and all. Then I was able to set defaults, F10, I think, but not positive, this was a couple of years ago, save and exit. Restart. No problem. Safe mode used a screen resolution that monitor could handle. Default settings set screen resolution that monitor could handle when it started up normally.

whacky, havent heard of something like that since back in the 386 days, think that happened at work to somebody, when did the screen come back? when it got all the way to safe mode windows screen or sometime before.

Safe mode windows screen is the first thing that I recall seeing.
Yesterdays experience was even wackier. Don't know if there was a corrupt registry or if he has a bad connection that we lucked out on for awhile. He's gone up north so I can't ask him if he has moved monitor and back to where he was or if he is still okay.
