Hi, iv been havin a few problems when trying to turn my pc on, iv had it for 4 years so it's an old compared to recent comps!! I'm able to turn it on but every time I do so the monitor comes up with the 'no input signal' message! I have tried connecting the monitor to my laptop and other CPU and it seems to work fine, so I'm lead to believe that it must be a problem with my video card but I'm not sure! Also there is a difference in the beep when the pc is switched on, it now beeps 4-5 times rather thn once! I would appreciate the help thank you!

PC spec:

Model: Medion MT8 (MED MT459)
Graphics card: Nvidia Geforce 7650gs 128Mb
MoBo: MS 7318 ver1.1
CPU: Intel Core2Duo E6400 2.13GHz
PS: 300W
HDD: 300Gb

ok cool thnx for the help!
Is the difference in beeps during the start up of the pc important? i kno that the bios has error beep codes, and i can hear a 1-1-3 beep sequence, i looked it up and it said something about CMOS needing replacement! What is CMOS?
