I bought a Dell Demention from a guy on Craigslist and
when I went to check it out it was lookin’ good, but when I got it
home tonight I tried to plug it in and for some reason it’s not
workin’… The PC turns on(get the lights on front workin and I get the “whiiir”) but the monitor isn’t getting a “signal”
and the disk drives wont open or anything. Any idea what could be
causing this? If any of you have anything I could try/check out I’d appreciate it. I’m
kinda pissed about it actually. Hoping I didn’t throw my money down
the drain
