Pc powers up but there is no display on the screen, its permenently black.

Hi there fellas.

I have had my comp for about 3-4 years. I have never had any problems but this week when I turned it on the screen remained black and said "no signal". Obviously there is no output from the graphics card and I have tried a second moniter which also failed. Im almost certain that this is a hardware problem.

When the PC boots up, the LED's on the flash card drives and floppy drive are permenently on. However, when the PC was working these lights would flash briefly and then go off while the boot sequence continued.

I have opened the case and turned the power on. The CPU fan and PSU fan are both spinning but the fan on the graphics card is not. The two DVD drives both work but there is still nothing on the screen.
Im not sure if the hard-drives have power because they are quite hidden.

Im am unsure of how to proceed. I thought I would seek some advice before physically taking it to a specialist.

My PC:

ADVENT T9202
Intel Pentium 4 HT Processor 550 3.4 Ghz
Motherboard - MS 7046
Seagate ST3200822AS 200GB SATA - HD
Seagate ST3200822AS 200GB SATA - HD
1024 DDR Memory - PC3200 (2 x 512Mb)
ATi Radeon X600Pro 256Mb PCI Express
Sound Card Realtek High Definition Audio (Azalia)
Artec DHM-G48 16X DVD-ROM
Pioneer DVR-108DB DVDRW

Thanks for spending the time to read this.
Any advice whatsoever would be great.

Hi, I have the exact same issue as yourself. Strange how they have happened at the same time too. So far I aint got anywhere with finding the solution. Will get some info from someone I know tommorrow. Will post here if theres any developments. Hope you could do the same Perhaps we both will get to the bottom of this

Does this computer have onboard video as well as PCI-Express ?

ie can you remove the "ATi Radeon X600Pro 256Mb PCI Express" video card.

Whilst trying to search for M/b pic, I did find the drivers HERE
But we will leave that until, the computer actually Posts (Power On Self Test)

This may be the video card has faulted causing system startup lockup.

You said "The CPU fan and PSU fan are both spinning but the fan on the graphics card is not." The dead graphics card fan is the most likely culprit - the graphics processor chip is probably overheating and shuts itself off to prevent burnout (at least my nVida cards do that, for ATI cards I dunno). First try another compatible video card (ideally ATI so you don't have uninstall/ re-install video drivers) to see if you get video output. If so, replace your video card's fan. If new fan (or new fan+heatsink assembly) doesn't fix it, then the graphics processor may be fried, hence you're then into replacing vidcard.

Good luck, finger's X'd for you.
