Ive just moved abroad, unpacked my desktop, an Advent computer approx 6 years old, set it up turned it on, boot screen appears logo of computer etc, and then on screen appears "no signal". Ive been inside the computer and discovered the graphics card has come loose, (this happened before, when i cleaned the inside of the pc) Ive now re-secured the graphics card in as it was before, of which there is no damage to the card, and same has occurred, everything is connected properly as it should be, it more or less boots up, then on screen the words appear " no signal" can you help!! so i can do this my self without the cost of myself taking it to engineer.
Many thanks. J.P

thank you all for yr responses im about to take a look inside now to make its in the correct slot and what brand of card it is bare with me guys 🙂)
 
Although you say there is no damage, that may be true to a visual inspection but electronically the card may be damaged.

Alternatively, this symptom also occurs when the GFX card is not getting sufficient power. This can be due to a failing PSU or simply the PCIe power connector not being inserted correctly or at all. The reason a card can show a POST screen and then give no signal is that only minimal power is used to display a POST screen but as soon as the OS call is made by the BIOS the power draw of the GFX card increases significantly, and therefore beyond the available supply. The card shuts itself down to self-protect.
 
please excuse my ignorance guys psu, is this the processor? my friend was an engineer, who is obviously not available at the moment he went into the bios and fixed the issue, ive done the same earlier but could not see anything to my untrained eye that indicated an issue to the grafix card, anyways bare with me im gona take a look inside and get back to you all, many thanks ;-))

by the way the power supply unit works just fine ;-)
 


everything is connected as i can see on the motherboard if the card as you say is not getting enough power how can i adjust this so as it functions properly. 🙂
 
My Highlighting.
OK there is a possibility that your mother board has onboard graphics and they are conflicting with your discrete card. This would have occurred when your discrete card came loose and the BIOS defaulted to onboard. If this is really your situation you will need to re-disable the onboard graphics so that the conflict disappears. Before any of us can advise you how to do that we need to know exactly what the motherboard is so we can give you a quick navigation to the right setting in the BIOS.

(PSU = Power Supply Unit, processor or Central Processing Unit = CPU)
 


thats great ill look now 🙂)
 
So by that socket I'm guessing you have an intel core 2 duo or something along that socket family. Anyways, I don't think the problem would be the CPU but if it is upgrade to this one: http://www.intel.com/products/processor/core2quad/

That way if you want to get a really powerful graphics card, it wont bottleneck.
But if I were you I would just get the radeon HD 5450.

many thanks,

Try and find a tutorial on how to set you're PCI card over you're IGP (Integrated Graphics processor), Often there is also a setting in BIOS on newer boards that allows the user to set either a PCI card or AGP card as the primary video device. Make sure this is set to your video card.
