The problem is that i'm not geting image on the monitor, it says "no signal". The problem is not from the monitor because it works in another computer. It started happening after I changed several things in my computer. I have a Medion Titanium MD8383 XL that has a Nvidia Geforce 6610 XL. I changed the memory cards from two 258Mb to two 512Mb, and installed a new CPU cooler, Verax quattro I , and a new VGA cooler VF-700AlCu. The new fans on the CPU and on the video card seem to be working. I tried with the old memory cards and it still didn't work. Where can the problem come from?
