Having problems with your eMachines W3118 AMD Sempron 3100+ 1.8GHz / 256MB DDR / 80GB HDD / DVD-ROM/CD-RW Combo Drive / Window PC Desktop ?

PC powers on but no video

\015 When I turn on my PC just the lights turn on and the powersupply runs but no beeps or video.\015

Answers :

Loss of video is one of 3 things.
1) Bad or loose video card - But you get normal sounds (you can hear the Windows sound when starting up) and normal beeps. Does not sound like your problem
2) Bad or weak power supply unit (PSU). Sometimes it appears that a power supply unit is working, but in reality it is not getting enough power, usually due to some bad capacitors (caps) inside. If you swap out the power supply you have to put one with the same or greater output watts in it. Output watts can be found on a sticker on the outside of the PSU.
3) Failed or failing motherboard (mobo). This is usually caused by failing capacitors (caps). Caps look like little soda cans and they should be perfectly flat on top and not bulging or swollen or leaking anything. Visually inspect those. A bunch of computer manufacturers and power supply manufacturers got bitten by a company that years ago was making poor quality (but cheap) capacitors. Seems this company stole the recipe for the capacitors but didn't quite get the mixture right and after 2-3 years these things started failing. I have seen several e-machines with this problem.
So in my opinion you have either a weak or bad power supply or a failed or failing mobo. What is happenning is that the computer does not make it through the Power On Self Test (POST) and that is why you hear no beeps and get no video. SO I beleive that you have situation 2 or 3 mentioned above. That is where I would start looking for your problem.
