blank screen - no beeps - poss cmos battery?

  saldobs 16:13 25 Feb 04

Hi - a friend's computer has not been used for ages. He has been given a digital camera and wants to use the comp again..! However, the screen is totally blank (I have tried 3 monitors using different cables etc) it says no connection.
Could it be the on-board video card or maybe the battery is dead as it has not been plugged in for months.
Also can I put in a video card and get rid of the onboard wiring?
Thanks in advance for anyone's help!

The beeps you refer to is the system performing a POST test (Power On Self Test). Since you are not getting this I would check the PC itself is getting power i.e LEDs and fans operating, if not then either the PC power cable is faulty or the Power Supply has failed.

i really dont think so. I would recommend getting another AGP graphics card and disable the onboard one in bios. Many cases have had this problem, but i haven't come across it being the power supply. It would either be faulty or not seated properly RAM or Graphics card, as you have onboard, i would suggest starting from there.

Hi many thanks for your replies, however, I decided to try a new cmos battery as it is a cheap option at £2.99!
Thankfully, I put it in and the screen came up good as new!
So it is worth remembering, a simple thing like a battery has saved my friend about £40 for a graphics card.
For future ref, how do I disable the onboard card should I want to?
