I've been asked to look at an old pc which isn't working properly - it powers up but there is no display. It's a shop bought pc, not custom build, made by fujitsu-siemens, so I'm stuggling to find out which motherboard it is (mainly because I can't get any display). The only thing I can see on the motherboard itself is SiS 964L. Can anyone confirm if this is the motherboard make/brand? Also, the bios gives out beep codes as it tries to boot, but I've not been able to find out what they mean. The beeps are 1-3-3-1, which i think will probably mean the onboard graphics aren't working. There isn't an agp or pci-e slot on the board, so I'm not sure if it's possible to get a graphics card. Can anyone shed any light on this? Thanks in advance for any help.
