Desu Posted November 2, 2010 Share Posted November 2, 2010 So i scavenged a pentium dual core from my friends comp, decided to put it in today put it in, and turn on comp. It turns on, but no signal is sent to the monitor so nothing shows there. i thought maybe faulty processor so i revert back to my old one. same problem still, so what do i need to do?

Jaaa!& Posted November 2, 2010 Share Posted November 2, 2010 Does the computer it self turn on? If so, the monitor cable might be bad if theres just no signal to the monitor, Need some more information as to what its doing before i give any more help so I can target the problem.

Desu Posted November 2, 2010 Author Share Posted November 2, 2010 computer itself turns on. and the monitor cable itself is not bad as it was working perfect before i switched processor. Quote Link to comment Share on other sites More sharing options...
!Chuck4Abuck Posted November 2, 2010 Share Posted November 2, 2010 do u have a voltage meter ? , make sure all ur new components are dust free . Then again this could have to anyone disconnect ur power supply to the mobo and try it again . Quote Link to comment Share on other sites More sharing options...
Jaaa!& Posted November 2, 2010 Share Posted November 2, 2010 Does anything at all appear on the monitor? Quote Link to comment Share on other sites More sharing options...
Desu Posted November 2, 2010 Author Share Posted November 2, 2010 well now the comp does not turn on at all. Smelled a slight burning odor for 2 sec. Quote Link to comment Share on other sites More sharing options...
Jaaa!& Posted November 2, 2010 Share Posted November 2, 2010 Something might be blocking your fan from running Quote Link to comment Share on other sites More sharing options...

Desu Posted November 2, 2010 Author Share Posted November 2, 2010 they arent. they both are working processors yet it doesnt turn on anymore Quote Link to comment Share on other sites More sharing options...
Saizou Posted November 2, 2010 Share Posted November 2, 2010 Well burning odor is certainly not good. If you are 100% sure both processors are working then it's either motherboard or RAMs. Any sound coming from hard drives? Quote Link to comment Share on other sites More sharing options...
Desu Posted November 2, 2010 Author Share Posted November 2, 2010 now no sound from any. im guessing something shorted out...though i dunno which Quote Link to comment Share on other sites More sharing options...
Saizou Posted November 2, 2010 Share Posted November 2, 2010 Easiest way to tell is to open the PC up and see if something is charred in there. Best bet is to try RAM on another PC and if it works then I'd say it's motherboard. Though in my case there were sounds of constant restarting coming from PC but it rarely managed to get past POST. Another thought, maybe it's the PSU or the fuse in it. Quote Link to comment Share on other sites More sharing options...
OnionKnight Posted November 2, 2010 Share Posted November 2, 2010 Lol sounds pretty bad. Burning odor is not a good thing that is for sure lol (is anything burnt?) Desu what was your previous CPU before you replaced it with your friends dual core? (this might be important to know) What you can do right now? Do a simple check. Make sure all you case wires are still connected and the 20+4 pin cpu connector. If all those are plugged in correctly and the computer doesn't even start up, light up, post or beep, then try to test if the power supply. How to test the power supply? Just short it using a paper clip. It doesn't hurt the power supply but just force starts it without the use of a computer (make sure you unplug everything from the power supply). If the power supply fan is running that means it is working Steps: -Turn off Power Supply Unit (PSU) -Find Green wire on the PSU's motherboard 20/24 pin cable -Find any black wire on the PSU's motherboard 20/24 pin cable - stick one end of a paper clip in the green wire socket and the other in the black wire socket. http://www.youtube.com/watch?v=4askospjx0E Quote Link to comment Share on other sites More sharing options...
