First time poster. I have a Dell Dimension 4600c that is about.. oh couple years old. I can't even recall, but older than three for sure. I am not the only one who uses this computer. I came to it tonight and it was off. I haven't touched it in a few days. When proceeding to power it up, the light went on, the fans went on, but there was no signal to the monitor and the monitor stayed in powersave mode. so, now i can't see anything or do anything to get it to start. on top of this, the keyboard is getting no power either. when pressing numlock or capslock, the buttons do not light up on the keyboard. when unplugging the keyboard and plugging it back into the back of the computer, they light up briefly then go away. the mouse, which is a USB optical Logitech mouse, is getting power, but since i cannot see anything i am doing, is useless to the cause. The only culprit i can think that has screwed this computer into not starting it Limewire. The other person in my house who does use my computer, uses Limewire, which i should have removed the second i saw it. I am thinking this could be a virus, but i could be wrong, as it could be a hardware problem. please help me fix my poor computer.

paigeislame, my guess is power supply. They can go South all of a sudden. Since you don't even get the keyboard lights, that pretty much says the machine isn't even trying to run the bootup sequence. A PS provides several different voltages and it can supply one and not another blocking bootup. Sadly, I don't know of any simple tests to run which would eliminate the guesswork. HTH. Ed in Texas.

Did you verify the monitor is plugged in and that the cables aren't loose? Unplug the power cable from the back of the computer. Wait a few minutes, then plug it back in and reboot.

The chances of it being a virus is practically nil. It's a hardware problem and the power supply is the best bet. For what it's worth to XP users: When you click on the 'Command Prompt' you are just causing the 'Command prompt' to be displayed. This prompt gives you access to the 'NT Virtual DOS Manager'.

checked the monitor and everything, it's not the monitor. i unplugged it and checked all the wires. still nothing. i am on a really tight budget. like. stupid tight budget. what's this gonna cost me to fix?

Did you try another monitor? "So won’t you give this man his wings What a shame To have to beg you to see We’re not all the same What a shame" - Shinedown

Hello Try to bootup on safemode use F8 when the first screen logo finishes just when the computer checks for disk dish or floppy disk keep clicking F8 then click on safemode and uninstall limeware or try restoring to your last good bootup its on the screen where the safemode is. GOOD LUCK!
