All i can tell you that its a packard bell 2326 pc 3 gb ram 500gb hard drive with a nvidia gx440 video card i only bought it yesterday, along with a new monitor. I cant tell you anything else as i cant get into the computor with the monitor not working, just the message no signal,
im lost ,removing a power supply from a tower to clean it should not make this happen to a computer ,i have cleaned hundreds of them .and only remember this one ,maybe because it only happened a few mnts ago , ,i cleaned one with can air and when i plugged it back in and it popped something inside and needed to be replaced ,
maybe the psu is bad,got another to try
