My new PC doesn't power up, ASUS A7V600-X, Athlon 2800+

Hi, Im desperate since i bought a new computer, every part, and when I fuinished building my computer it won't start.

I have an A7V600-X Asus Motherboard, 2800+ Athlon processor. I have tried with one and two ddr memories.

The thing is that when i try to turn on, it doesn't do anything, neither something on the screen nor a beep or sound.

I have tried changing the video card, disconecting my cd and hd, even with the power from another computer (I don't know the name of this part in english, it is the part where the power cord plugs in).

I have no idea what could it be, and I'm going crazy.

By the way when i try to turn on, the pc fan, moves like a 1/16 of a circle and stops, but only does this when it is the first time i try to turn on since i unplugged and plugged the power cord.

This sounds like either a bad power supply or a bad connection to the motherboard. You said you tried another power supply, so I'm not thinking that the power supply is actually dead. What are the wattages on the supplies that you've tried in the system? Modern parts draw a lot of juice.

Ok, I got it to start and it worked for a bit but know i have a more serious problem.

When I was installing drivers and programs, sometimes when i restarted the keyboard and mouse wouldn't work, so i went to asus webpage and saw that a release of a bios update fixed that. So i go and flashed the bios to the new bios and it somehow was corrupted or damaged and my computer would't start, so I put the old bios again, but now my windows xp is really slow.. it takes like 10 min to go through the logo with the bar below, and then takes even more to finalize initializing.

I thought that format and installing a new windows would help, but instalation is very very slow also.

What could be the problem?

It sounds like things have gotten badly underclocked, either the CPU, the various buses, or both (both being more likely as the various speeds are related by multipliers). I'd poke around the BIOS menus to see if something has been set absurdly low. The BIOS flash having been corrupted makes me think that there could be all manner of little things broken.

could it be that a minor but nevertheless important part of the m/board is damaged?

Thanks, I found the problem this weekend the Bios setting for CPU cache was disabled, I enabled it and no problem at all.

Thanks you guys.

Could you please tell me what you did to get your computer to work?

I have:
ASUS A7v600-x
3200 xp+
two 512 ddr 400 mhz ram sticks

I too cannot get the computer to boot up, only the power light is on and fan spinning.
