Just attempted my first "build" and cant get it going. Its an old case (make unknown) but fitted an Elitegroup 755-A2 mobo, Casecom 300w PSU, 512mb, Sempron 2800 CPU and an ATI 9250. I know for certain the PSU works as I tested it in another PC but I dont know if Ive fried the mobo during fitting or the cases Power button isnt working.
I bought a multimeter but cant find a decent tutorial on using it and the A+ Study Guide isnt exactly descriptive. I would like to know if its the case or the mobo I have to replace though.
You can probably tell by the cheap components that Im unemployed so money has to be spent wisely. Any advice would be appreciated.

Unfortunately, what I bought was only a test probe with a few lights. This is it here.
I have a question. If the PSU is plugged in and switched on is it pushing out power or does the computer need to be on? (By that I mean, hitting the power button tells the PSU to supply power)
The reason I ask is, that while I know the PSU works I tried probing one of the molex connectors but got nothing.

An update.
My partner has just confessed that she had some kind of air freshener on the case which then leaked everywhere so I think the mobo could be the problem.(I wondered why it smelled so strong).
As punishment she will be paying for both new case and mobo. :thumbsup:
