Specs: Windows 7, 2
Computer was working fine for a good 2 years and suddently after a restart there is power but nothing showing up on the screen. I tried to clear cmos, changing power supply and memory and that didnt work. If there is a way to find out if its the motherboard or cpu without taking it to repair shop or testing it out on another pc I would love to know.

have you tried another monitor? another graphics card?

are you getting any beep codes? or or light-flashing codes? do you have another slot on your mobo you can try the graphics card in?

You have Ispiron 510m below the title but it does not have "NVIDIA GeForce 7100 integrated"

Tell us the make and model of your brand name system, or if you have a generic desktop system, the make and model of the mboard.

The specific model of a brand name system is often shown on a label on the outside of the case somewhere, or it can often be determined by going to the brand name's web site and loading a program they have available, if Windows is still working, on the subject computer.

If it's a Dell computer...
Go here for how to find the Service tag "number":

Tell us what it is.

If it's a HP or Compaq computer.....
Go here:
Scroll down a bit.
Look for the similar label on the outside of your computer.
Quote the specific model number - that's at the end of the first line.
Quote the Product number - that's on the third line.

If it's a Lenovo computer
Find your specific Product number and tell us what it is:

Finding my product number

The model, sometimes the make, of a mboard in a generic desktop system is usually printed on the mboard's surface in obvious larger characters, often between the slots.

Since it last worked properly all the time, has there been a power failure event that happened or lightning strikes in your area ?

"nothing showing up on the screen."

No video at all while booting,

or do you always have video while booting BEFORE Windows loads but not AFTER it loads now ?

"its Acer Aspire M5641 "

"I tried to clear cmos...."

Did you move the jumper back to it's "normal" position ?

Settings in the Cmos can't cause the problem you're having. Even if the Cmos battery is dead, that wouldn't cause your problem.

Bioses don't spontaneouly stop working properly.
However if you flashed the bios with the wrong bios update or if something went wrong while flashing, the mboard may not boot after you have attempted to flash it.

", changing power supply,,"

What brand is the original one ?
e.g. If it's BESTEC, that MAY have damaged your mboard.

Wast the fan for that power supply spinning and blowing air out of the back the case after you first had this problem ?

The specs show a 300 watt power supply, but they also say it can be more than that. Does the original one show 300 watts on it's label ?

Did the other power supply you tried have that capacity or more ?

You have an available PCI-E X16 slot.
Have you installed a video card in that slot ?
If yes, what model is it ?

"... and memory..."

There is usually absolutely nothing wrong with ram that worked fine in the same mboard previously.
Not all ram that you might think should work is compatible with your mboard.
Installing incompatible ram modules can cause the mboard to NOT boot when nothing else is wrong.
Install only the original modules if you know which ones they are.

There is usually absolutely nothing wrong with the CPU that worked fine previously even when the mboard is defective or has been damaged

Failing PSs are common.Sometimes they damage the mboard while failing.
Defective mboards are NOT common, but some have the following problem...

Some mboards develop this problem - electrolytic capacitors were installed on them that were not properly made, and they fail eventually - the mboard manufacturer didn't know they were improperly made at the time the mboard was made.

Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .

What to look for, mboard symptoms, example pictures:
Home page that site
- what the problem is caused by
- he says there are STILL bad capacitors on more recent mboards.

Pictures of blown capacitors, other components, power supplies, fried Athlon cpus, etc.:


You haven't provided enough info about what your symptoms are.
Provide as much detail as you can come up with.

What are you seeing that isn't normal besides no video ?

Are you hearing the beep you usually hear while booting, or no beep, or beeps that asren't normal ?

Most desktop mboards have an led that lights up when the power supply has live AC power to it whether the computer is running or not. Does that light up when the power supply is connected to the mboard ?

Is the power led lighting up ?

Is the hard drive activity led lighting up and blinking like it usually does while booting ?

Is the CPU fan and the hard drive spinning ?
