Worked well till I tried to install sff video card. On start up green light comes on, hd starts for a few seconds. The total shutdown for 4-6 seconds. When pc starts up a second time, all fans screen into turbo. Changed out ps, switched memory, reseated cpu. I'm at a total loss! Any body have an idea that I can use? Thanks. Thom

Re: Won't boot at all
Hi there plug the monitor into the on-board video, if the machine boots up go into the bios and disable on-board VGA, save settings and turn off the PC then install the video card again to see if it worked.

Do you mean the monitor's power light starts green and then turns orange when you turn it on? Most monitors will go to a power saving mode when they do not get a signal from the computer.
The Dell GX260 has a green power light when on. When the computer is off, the light is off. If it is green and blinking, then the computer is in a power saving mode.
Diagnosis: start with the obvious: is the monitor cable plugged into both the computer and the monitor (if not permanently connected to the monitor)? Are you connected to the active port? (You can add a video graphics card in most desktops. The motherboard video port usually needs to be disabled to use the card ports. If you plug in the monitor cable to the disabled port, it won't work.) Is the monitor set to the correct input? (This applies if the monitor has several ports. In that case, there will be a Source or Input button on the monitor.) Is the computer on? The GX260 has the power button on the front. (Other computers have the power button on the top.) There is also the power supply switch on the back which needs to be on.
Next try a different data cable between the monitor and the computer (if you can). Try a different monitor. If a second monitor works, than the monitor has a damaged main board. If the second monitor doesn't work, then the video graphics adapter has probably failed. Replace the add-on card, if in use, then boot in the safe mode to remove the old graphics driver. Then install the correct driver for the graphics adapter.
Note: the computer and the monitor should both be off when you connect the cables. Then turn on the monitor first and set it to the correct source before turning on the computer.)
Hello, just start the computer an while starting (bios post) touch the del or esc or f2 or f4 just try one of theese when you can enter the bios menu then you go to start order and you choose first dvd/cd rom and second hdd0 always go to save it and exit, the computer wil restart then put in the cd/dvd rom drive the windows cd, restart the pc and when it says some thing like push enter to boot from cd/dvd rom then you push on enter and follow the instrucction till the end! success!
try a different monitor could be video card problem best if can try a known good one does power light stay green and hd light flash like activity continues, can you boot in safe mode, if so might be video driver , also looked for popped capacitors on mb , if computer actually goes off try a know good power supply
If you get only one BEEP at boot then the computer is working..
Do you have a 2nd monitor to test with?
if it BEEPS more then once...
pull out your mem chips and test,,
If itt works them one of the mem chips are bad if not..
pull out all pci cards and test.. if it works its a bad card...
if not unplug all HD and CD roms and test.......
If not fixed yet it maybe a onboard video problem...
But IF you put a video card in b4 the problem started then your bios may have auto set it sellf to PCI/AGP mode.
Check bios setings,, look for onbord setings for the video
I checked the specs on the video card thinking it must be PCI-e and not old style PCI but in fact there is an old style PCI meant for just what you are trying to do. The problem is the memory at 512meg plus the GPU put your power requirements at 300w and I bet you have at best 185w in those units so they won't even start and you won't be able to cram the bigger power supply in there. Go with a card that has lower specs and 64 - 128 ram and you should be ok. Just check the power req.
