I have not use this Desktop for 2 months, yesterday i reinstalled the window, everything worked fine, i turned it off because it does not have any wireless card and could not plug to the router since it is so far away. So i waited till today, i bought the Wireless USB, i turned the system on, but nothing show on the monitor. Everything seem fine, all the fans are running, the graphic card is running, does not look like it has any problem, but it just did not show anything on the monitor. I checked the monitor, it worked fine, all the cabel are tired. What could be the problem? The only thing i can think off right now is that the CPU is dead. What do you guys think ?
