Hp dx2000 MT

I have hp dx2000 mt PC and if I power it only the PSU and the Hard drives comes on. Both the CPU and chassis fans are not working and the system is not coming up. I tried both the PSU and the CPU in a different hp machine and they were all working alright Please what can be the problem now?
Please i need your help.
Thanks

Can you tell me what was it like before it started doing this ? Was there ANY power surges or lightning strike’s close by… This is not a good sign,It usually means the Motherboard went out… Is there any Video ? can you get into your Bio’s ?

Thanks for the reply.
Well I was rendering a wedding coverage footage and all of a sudden the monitor went to standby mode so i decided to move the mouse and the screen never power up again. But i can still here the system running and all of sudden i then realize that the the CPU and chassis fan are not rolling so i quickly turn off the machine. For about 10 minutes I try powering it on again and only the drives with the PSU comes on. The system it self refuse to power up. I can’t just now figure out what to do to the motherboard because I tried the CPU, RAM and PSU in a different hp dx2000 machine and were all working.

Yea! it sounds like the Motherboard fried,How old is this computer ? Do you have computer skills ? If you do, You could change the Motherboard if it is worth it to you..
If you would like to change the motherboard,then give the specks/Info of your computer… Make /model …

Yes I will like to change the motherboard.
It’s model is hp dx2000 mt (micro tower) with a processor Intel Celeron 2.60 GHz and 1 GB of RAM.

It says it is a 478 socket,I need a screen shot of the back I/O plate..Also you need a screen shot of the inside..

I notice someone selling this model refurbished for only $69 on ebay. It could be good to buy the whole machine for parts. from what i can see its a micro atx motherboard which would likely cost you around the same as this whole system.

Yea ! You have to be real careful on eBay, You could be getting something worst than you already have..If it was me,I would just buy either a new Motherboard Or get Another computer… You can get real nice used PC’s for cheap now days..You can probably find a 3.4 ghz or 3.6 ghz with 1 or 2 gigs of ram for about $160.00 bucks.
I would have to look at one of my places… take a look here..
