Think my new psu burned out my computer

I was getting help in this thread: http://forums.afterdawn.com/thread_create.cfm?forum_id=111
But the power supply I ordered would turn on, but my computer would not turn on. I tried it again today. I put the new psu in, turned the computer on, and the psu turned on, but the computer would not.

I turned it off and put the old psu back in, and same problem. Psu turnes on, but the computer does not work. the lights on the keyboard turn on, and the light on the motherboard is on, but the computer does not turn on.

I think the new psu fried my motherboard. What can I do?

 

do you get any beep codes when you power up PC ?

 

Nope. No beep codes.

 

i doubt it fried your setup, how many watts is the powersupply what kind of hardware do you have in your machine?

eg processor etc.

 

The computer is a Gateway 836GM, with a Pentium D 2.8, 1G of RAM, a 250GB HA and a 500GB HD. The original power supply is 300W, and the new one is 650W (http://www.newegg.com/Product/Product.asp?Item=N82E16817162014).

 

wow 650watts on that pc what were u gonna do with that? well it probably fried the motherboard b4 u throw it out try removing the battery of the motherboard or clear the bios by the jumpers

 

The new video card I have needs 450W, and the psu needed to support SLC ( I think thats what it is). And I was told that you can always use more watt's than what the computer came with.

 

Sorry posted this by mistake..

 

yeah slc sli, same thing... so the gateway you bought had a pci express slot in it? or is the card you bought an AGP card? What kind of video card is it?

 

Here is the card: http://www.newegg.com/Product/Product.asp?Item=N82E16814130017

Here is what my computer is doing (I have the original power supply in). I turn it on, and it sounds like it is working. The fans start up, the lights on the keyboard and mouse come on, the light on the motherboard comes on, the speaker light comes on, the light on the back port where the ether net cable connects is on, and it sounds like the hard drives are spinning. The monitor stays black and the power light on it just flashes. I tried two monitors that I know work, it is not the monitor.

I leave it on five minutes or so, long past the point where windows should be started, but no sound from the speakers.

 

from the gateway website it says it's got an integrated video card as well... i'm not sure if they made all of these towers the same because i t doesn't say anything about a pci express slot... did this computer originally come with a pcie card or were you using the integrated card before?

chances are, if you just plugged the video card in, your old video card is still the primary display device. Plug your monitor into the integrated vga out and go into your bios. Change Depending on your bios you'll have to look around for video settings, just change it to the pcie card, save and turn off the computer. Plug your monitor into the pcie card and it should work.

I don't know why you bought a 650w PSU for a single card either... usually the min is 600W for an SLI (two card) setup

EDIT: you're probably not getting to windows (no windows logon sound) because of the hardware conflict causing your system to hault...

 

I do not see how it could be a hardware conflict. It is only the original parts. As I said, the computer did not work with the new psu, so I never put the new card in. And yes, it has an integrated video card.

And I went with the 650W psu because it was the same price as the others.

 

i'd say strip the machine down to the bare essentials. Mobo, Processor, PSU and Ram. If you have the available hardware, try each component in an other machine... before you do that try resetting the cmos a few times

 

How do I reset the cmos? And I should just send the new psu back right? It seems like the problem started from it.


Thank you.

 

TO reset the CMOS take out the cell battery for like 5 min then put it back in

 

Thank you so much! Reseting the CMOS worked!

I am going to send the new psu back. When I order a new one, what is the max wattage I should get? The original one is 300W and the new one is 650W.


Or do you think the new psu is safe? Do you think it could damage the motherboard or anything if I try it again?


Thank you!

 

u could try and c if it works if it doesnt then get a 500watt power supply u wont need more than that

 

But if I do try it again, it can't cause any damage, can it? That is my fear.

 

dude putting a 1000 watt power supply wont do it ANY dmage now if ure 650 watt power supply is damaged then yes it could cause damage

 

Thank you.
