CAN´T TURN POWER ON

There are two computers driving me mad in the office because when we turn them on the green lights go on and I hear the HD power but the screen is blank and nothing goes on. After turning them on and off for about 10 min, they finally start up. I´ve tried changing the ATX "power box" and pluging the PCs in other sockets but with no results. Could it be related to the fact that they are both Celerons? What can I do?

My Celeron machine wasted its battery after 1 1/2 yr of use; symptoms were the same you describe: machine doesn't boot, and only ofter letting the machine on a while (so battery re-charged a bit of power) I could put machine to life.

Of course, once booted, I had to re-set all lost parameters from BIOS.

The final and total solution: to buy a new battery. Just spend $2 or $3 to see if that's the problem, it really worths.

With the computer turned off, and the case-cover removed, take a hair-dryer, and blow hot air over the computer, until it's "warm".

Then, turn the computer on.
If it starts correctly, then you have some intermittent connection, which expands/contracts as the temperature changes.

Also, check that the BIOS chip is securely seated in the motherboard.

Also, check that the CPU is securely seated in its socket.

Also, try "part-swapping", i.e., move the CPU to another computer, since a total lack of activity after power-on suggests BIOS or motherboard or CPU problems, and, of these three parts, it is easiest to try the CPU in another system.

I would try reseating the video cards and make sure they are in tight. Also make sure that the core voltage, bus and multiplier speeds are set to the speed of the chip. Make sure they are NOT overclocked!

Thanks Viking!

You´re right. They´re Celerons and after changing the batteries they work just fine.
