Having problems with your HP PC Desktops ?

I have an HP pavilion 250n desktop that i'm trying to fix for a friend. when i boot up the system, everything boots up perfectly normal, except there's no video output at all. it has a nvidia geforce 4800x graphics card installed and i've tried switching between it and the integrated graphics on the motherboard with the same result. i wouldn't expect this to be a cmos problem, but i'm open to any suggestions and help that i can get. any response is appreciated. thanks


Answers :

The problem could be:

Bad slot video
Bad video card
Memory
CPU
Bad motherboard
\015\012
\015\012Go to bios and set only one video card - (disable AUTO)
If the card is AGP be sure that the board accept that card (1-4-8x)
If everything is ok, but the problem continues >> replace the memory.
\015\012If after that the problem continues, >> make sure the cpu is inserted fully and seated in the socket..........or >> replace the cpu
\015\012if the problem continues, be sure that the board is not touching the case
if the problem continues>>replace the motherboard

If neither the onboard video and the GeForce video work, the problem may be the Ram. If it has 2 dimms or more, take them out and insert one at a time, powering down/up the computer each time you swap the memory.

\015\012I would clear CMOS, just in case.
\015\012
\015\012If that does not do it, I would suspect that the Processor got over heated and is causing the problem. Is the CPU fan working? Is the Power Supply fan working?
