Computer Turns On, but NO Display on Monitor

Hi guys,

I just started my PC after a while & it turns ON, lights turn on, but there is NO Display on Monitor.

I did some research on Google about this issue & did a few things.

1). I removed all the hardware, except processor & power supply. Turned On, but same issue.
2). I tried after removing ram, & then by switching ram slot, but still no use.
3). I removed my HD 3450 512MB graphics card & plugged monitor in Built-In Monitor port & Vica versa (In Graphics Card), but no use.
4). I removed hard disk & DVD rom & changed their power cords, but no use.
5). I removed the computer cord, & pressed & hold the "ON" button for 30 to 60 seconds, but no use.

It was working fine a couple of weeks ago, but then I turned on & it was not working anymore. By the way, when I turned on it acted a little weird before going dark. Actually when I turned on, it took a long time to get to display & then window was also working weird, then I restarted a couple of time & I though it was my hard disk, (who sometimes have power cord issue that works fine if we change it, but its not that).

Any idea how to fix this issue or what is wrong with my computer?

Thanks.

If trying onboard display (connecting the monitor to the mobo back panel) still not having any display could be serious problems....

try clearing cmos and try onboard VGA again (the dedicated not installed) ... if it still
no display, it could be the mobo died, or the monitor died...

First unplug/disconnect all power source for all device (monitor, speaker, cpu, etc....)

In the mobo there a silver coin like battery (CMOS battery), remove it for 5 min.. (make sure no device is connected to power source/electricity)

Then re-install it after 5 minutes...

it will clear CMOS and reset the bios setting to it's default state (factory setting)....

Oh well, I did this. I pulled the small battery out for 10-15 minutes. Then pushed the ON button a couple of times. Put the battery back in & turned it on, but still no display. :(

I once had a problem like this, i had shipped my new desktop from my homeplace to my college, i tried pretty much everything that you listed and maybe more, in the end i gave it to one of the it guys at my college, he said the motherboard got shocked, got that swapped out and been running fine since then

Something interesting happened today. I took it to a local motherboard repair center, they plugged in & pushed the button, it actually gave the Display, BUT just the Display of the MSI Welcome Screen & stuck their. It didn't proceeded. The tech guy check it with my Graphics Card and then with Onboard vga, same thing happened both times and display showed up & stuck at the MSI welcome screen. No Keyboard input worked or no Setup or BIOS entry.

I told the guy to check the board & he highlighted its overheating.

Any thoughts on this one? What could be the Problem then?

Looks like the mobo is faulty...

it hard to pin point the problems it could be one component in the board fail, it could be the heat sink is loosened, etc...

If changing the mobo fix the issue then I think that the best solution...
it will quite hard to fix failed mobo....

Yes, I think I should replace the mobo. Even if it works, I've doubts it will support the Upgraded processor I'm planning to get for it.

Thanks.

When I had this I just got done putting a new processor in. When I took it off the pins were bent on the processor. When I put them back to normal and put it back in it worked fine. The pins are very delegate.

Turn off ur pc remove the cmos battery first, then short it by the help of a screw driver(u can see a silver metal with positive and negative, short them)
Then clean ur ram(remember u must very careful while inserting ram)
Then switch on ur computer a black screen asking Cmos time and so and so automatically it moves to ur desktop screen after that by turning off again u can insert cmos battery and on ur PC again and adjust the time...when desktop screen appears again...
