Your computer is not posting that is why you do not hear a beep. This can happen for 1 of 10000000 reasons but I would start with checking the RAM then all the other hardware to find a loose connection/dead hardware.

Wont Boot 1st PSU Flashing Amber


standard troubleshooting:

1) I've seen power sources appear to power up a system, but are somehow broken just enough to not get the system to POST (do you have another system you could at least borrow the power source from?)

2) pull anything you can so that you just have mobo, power, cpu, memory, and graphics.

2a) try using just one memory chip (and try each chip you have, or best to borrow a chip from a working system); even try different slots

2b) if onboard graphics, try a known working graphics card addon

2c) does the screen power off (like normal sleep) or system shutdown? if latter, try re-thermal pasting the heat sink to the cpu.

No video


Does it appear that everything is booting up, hard drive spinning? But a blank video screen with nothing at all? I had this several times happen to me and it's always been a bad CPU.

Rockola download jukebox lights and screen do not turn on, but "insides" seem to be running ok. Screen says no video connection, then goes blank. Video cables are ok.


The lights inside most likely indicate it has power and is waiting for power button to be pressed. Could be as simple as power switch is failing.

Computer won't do anything, keyboard does not light up, screen is blank


So there is not so much as a BIOS message on screen? Any beeps?
If there is no life at all, you have a CPU/motherboard failure. This may be direct or indirect (e.g. no power to MoBo). Check your connections.
Otherwise, your boot device may not be operating. This is usually a dead or disconnected HDD. Check that it is plugged in. Does it get warm? Can you feel any vibrations from it? It should spin even if your cpu is dead but MoBo is alive.

I have VGC-LT23E all in one computer. It cost me a lot of money. When I turn on cpu I get nothing but a black/blank screen but I can hear the windows sound and fans are running. I just can't see...


If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp.

Gateway T-1625 Laptop won't boot up - screen blank


Yes, if the CPU/motherboard will not POST (Power On Self Test), then changing the CPU is the only thing that you have not tried.

USB PORT NOT FUNCTIONING


does your machine make it to the windows login screen, or does it fail before.

I think you haven't installed you CPU correctly, or maybe did not put heat sink compund evenly on the heat sink, and that causes the CPU to overheat and freeze.

2 ghz processor running at 220 mhz


Hi,

Have you tried right clicking on the desktop (opening Display Properties), clicking on Screen Saver tab, Clicking the Power button, and setting the power schemes to Home/Office Desk? If its set on laptop it will reduce the processor speed when running on battery. I have noticed that even with it plugged in that some times it will run at half processor speed. Try that out.

Have a great day,
Armymason
