my computer turns on but no display on monitor

still in need of help!!
 
I have had this problem before.
The most common mistake is that computer builders always connects the 20/24 pin power connector the mobo, but they never connect the 4 pin power connector to the mobo.
Check if you have the 4 pin power connector connected.
 
yeaaa its in. ive said ive tried everything... soo yea i did check if it as in already
 
Try a different gfx card, sometimes if the power regulator circuitry is damaged (static, sweat encrusted or otherwise) you'll get nothing when you power up, not even a beep.
 
yea just upgraded to the 8600GTS. Because i thought my old GFX was broken. So ive basically done that alredy the GFX card is new. the old one has the same problem
 
why do you have two threads going on about the same thing?

Are you getting the "No Signal Input" text on screen or nothing at all.

This may be stupid but is the DVI cable plugged in.
 
lol yes it is. and it does say no signal. its a new DVI cable as well as the old one didnt work came with my new GFX card because the old GFX had this problem so i boght this gfx card for no reason.
 
CPU might be dead
 
Remove everything and let the cpu only. Clear CMOS and/or remove battery for 10 minutes or so and then power it on. It should give you some beeps...that means it isn't your cpu. If it doesn't try it with another psu. If it still doesn't then most probably your cpu fried
 
omfg. damm later on ill go buy a CPU from frys electronics.

A bad CPU will normally post with a view on the monitor...Now I do say normally post,but not always!
 
hmm can it be my mobo? but everything works. the mouse turns on from the mobo usb. and my fans spin

Now thats where I would be guessing the problem is before the CPU.
 
The way you describe its the mobo. I had a similar issue with a different brand. Thought it was the CPU. Luckily I had a spare one lying around and it didn't post.

Like I said in ur other thread try all those steps.

May be u can try this.

Pull ur mobo with your CPU, HEATSINK+ FAN and RAM. Put it on a Anti-static mat. Plug ur Video card. Plug ur power supply connectors (24 + 4). Turn on ur psu. Turn on ur mobo. If it comes up then u didn't install the mobo properly in ur case. It is shorting somewhere. To turn on ur mobo, use a screw driver and touch the 2 pins on the mobo which says pwr switch and it will turn on.

Did you put the mobo spaces before re-installing ur mobo?
 
My m8 is having the self same problem..He bought himself a ATI x1900xtx for an upgrade from an ATI X800 and found the cpu was running a little hot.So he ordered himself a new heatsinq and fan for it,he changed the heatsinq and voila no post screen no bleeps no display..? He has since tried his old(working)x800 back in and still no display..he's lost iam lost..So any help for this guy will be of help to my guy..


Ps:I have linked him this post on our forum and told him to to keep checking..
Cheers for any help which may help my friend..:)
 
Might be worth to check the contact pins in monitor, video card and monitor cable.
 
im not that good with computers sooo whats TIM?


MOBO SPACES?
 
Err, someone smack me if this has already been mentioned, but are you plugging the monitor into the back of the GPU or the board I/O?

First time I used an 8800 I plugged it into the I/0. I stood there for a minute thinking 'hmm.. hmm..oh hah!'
 
lol of course ive done that.... =D *SMACKS IN THE FACE*
