I recently cleaned a Desktop for a friend... IT WAS HORRIBLE... it had ROACHES and all sorts of things in there specially the a amount of dust was starting to look like MUD.

Before i cleaned it it started and shut off after like 10 minutes probably because if all the dust making the computer overheat.. So i cleaned it and when i was about to turn it on it DIDN'T want to turn on.

Everything is there all the cables are plugged in the right spot.. And i noticed when i plug in the power i see my room light dim a little and then go back to normal but it isn't really that big of a deal because it does that with all my electronics.

If you guys need specs let me know thanks

Make sure the on/off switch on front of the computer is correctly seated to the jumpers on the motherboard. You might have jarred the connection when cleaning it. Bring the computer into another room and use one of those power outlets. The outlet you're using may not be outputting proper voltage.

If no joy so far, swap in a power supply of equal or greater wattage. You'll have to hunt one down. Once you do that and the computer will still not power on, then you'll need a new motherboard.

follow up... the computer dies.. after a while... and it kinda bothers me.. any ideas power supple is still good coz the motherboard is still lit and the power button is still lit up too its just the cpu fan and the hard drive that arent on... could it be overheat? or battery?

When the computer is on and you can see the "desktop", are fans spinning ?

BluerjB · « **Reply #6 on:** April 20, 2010, 06:58:59 PM »

no just the fans stopped spinning... and i figured out that if i take off the pci Ethernet card it turned on and its working again.. i cleaned the card with a q-tip a little and plugged it back in currently the PC is running but im waiting if the Ethernet card is going to make another effect to the PC.

I don't understand what you're saying.

When the computer is ON (booted) and appears to be running ok, are the fans spinning?

ohh yeah they are..

Are you sure that the power supply you put in the computer is at least the same wattage as the original supply ?

If you got it working by removing the PCI card, it's a sign that the power supply is not sufficient in its output. Removing peripheral components reserves power for the rest of the system...

OK... on the old one it says that it cant exceed 160 watts and on the new one it says cant exceed 230

download speed fan and post your voltages and temps..

Post the computer specs as well.

Are you sure those voltages are for the entire power supply, or just one voltage.

Those are both really both low numbers.

i looked it up on the internet and the one i got installed is a 250 watt and the old one was 300 watt but the main problem was that the computer would die... even though the 300watt was still on there

Was there not an ethernet jack on the mother board? What other cards have been added since the system was new? Video cards, sound cards, etc.

The computer is dying because the power supply is defective. Just because it is a higher wattage doesn't mean it's going to work. Using a lower wattage power supply helped isolate the issue, but a 250 watt supply is evidently not enough for your needs!

You'll need to get a power supply similar to the wattage of your old one... 300 watts or higher..

OK, and i took off both the pci cards because i figured out through rthompson80819 that there already is a Ethernet plug on the motherboard. lol i feel stupid not seeing that at the first place

EEVIAC · « **Reply #19 on:** April 20, 2010, 09:13:44 PM »

Leaving the card removed is a good work around, for now..

If you run into performance problems in the future, you'll know why... You might think about setting aside some money for a new supply, for later on..

BluerjB · « **Reply #20 on:** April 20, 2010, 09:35:53 PM »

ok

thanks people for your help

rthompson80819 · « **Reply #21 on:** April 20, 2010, 09:40:40 PM »

This is just a WAG. The ethernet port on the mother board is probably 10 Mbs connection and the PCI card is a 100/1000 Mbs card, but unless the machine is on an extremely high speed internet connection, or on a corporate network, it's limited by the connection speed of the ISP.

And I agree, a bigger power supply should sometime be in your friends future.

How can you assume that ? ?
Many boards were shipping with 100/1000 onboard for the past few years
