This kind of problem can have many causes. Here, most probably your motherboard is not responding to the 'switchon' current and therefore the process ends. Start by cleaning the RAM 'teeth' with an eraser.

I can only add 2Gig of Ram on my Acer Aspire t180 XP. The screen flickers when I add more. Help

The usual cause of screen flicker is a lack of power getting to the graphics card. The best way to check this is to remove another component to see if the flicker stops. If it does stop you need to upgrade the power supply.

Upgrading the power supply is a simple job. Let me know if you need more information on replacing the power supply.

When connecting laptop with charger it shuts down . with battery no problem.what could be the reason. tel me what to do. suraj tanzania

There could be two possible faults that could cause a problem like this:

First it could a short on the motherboard at the power supply connecter, which to repair would consist of taking the motherboard out of the laptop, and maybe replacing the power supply socket. It could also be a faulty componant on the motherboards power supply circuitry.

Second it could be the power supply itself, the only way to test this is to aquire a new power supply, you could take the laptop and power supply to your local pc store, explain the problem to them and ask if they could test it with a new power supply, if it works with the new power supply then you can buy it, if it dosent then you know the problem is with the motherboard. hope this helps and please post back the results, thanks.

Pc won't turn on. doesnt do anything after the power button is push. no lights,no sounds, no fans, nothing.

Most commonly that is caused by a burnt out power supply. You will need a little knowledge of assembling computers to know how to replace one, but an electronic store like Best Buy should be able to help with the purchase and installation of a new power supply.

Good luck.

When pressing the power button, the fans only come on. I checked all the connections, and tapped the power button, the fan can on briefly then it booted up. Why do this happen, and how can I prevent it...

There are a number of causes but the most likely cause is a faulty power supply. Try a different power cable to the power supply first, then try a different power supply to see if this solves the problem.

Let me know if I can be of any further assistance.
Best wishes,

Dell Demension C521. Dead! Nothing! Even the little led light on the motherboard.

This is most likely caused by a power supply failure. If you have or know someone who has another power supply you could use for testing thats where you'll want to start.

Hope this helps.

Emachines e3038 - Will not start....

This could be caused by a bad power supply, bad memory, or a bad processor fan.
First open the unit and clear CMOS, then reseat the memory. power up.

If it powers up, check that all the fans are working.

If it still won't power up,power off the unit, take out any boards that are in the unit. Then power up.

If this fails you may have a bad power supply.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Not sure about updated power supply

Gee. If HP recomends you not to hook up the extra four pins it must be because the four either go nowhere,which may cause a short or ground condition.Or that the extra pins will power something that will then  be in excess andd cause it too burn out. They know what will happen and for that rwason caution you not to do it. Of course it is you machine and  if you have extra money to replace things with go ahead and do it if you really want to know that badly.

Power supply problem

You know first of all you must b sure of what electricty voltage iis supplied at your home.. well im from maurotius and here we are supplied about 230v,therefore it is recommended for ur to tune our power supply at 230v.. But sometimes there is a high frequency of voltage which passes through our cable and this may cause prob.. the best solution is to try to change your power supply..this might b the solution for your problem. dont worry as its not expensive.. if still you are getting problems,then try to serach for a pc technician,if you do not know anything about power supplys,then never try to play with it.. it may cause damage to other parts of your pc.. mail me at if you still have another problems.. take me as your friend..
