My computer used to work just fine untill a couple of days ago when I tried to boot it. All the fans started spinning at top speed, the led of HDD activity went on, but it wouldn't go into my BIOS screen. So I shut it down and tried again, but this time the led wouldn't even go on. I left it on for a while, but no progress. Since then it won't do anything but turn on the fans at top speed. I have no good understanding of computers, except for the basics so I wouldn't have a clue what is wrong with it. I know that everything is compatible since it was working fine before. Any suggestion would help.

Re: My PC wont boot
This is a sign that the bios is corrupt and you will have to remove the side of the pc tower and on the motherboard look for a 2 terminal commector, this can be labelled CLRCMOS, CLRRTC,or a 3 pin JBAT1, there will be a plastic cap if its a JBAT1 terminal, put from pins 1-2 to pins 2-3 then back again, if its the others then they have to be shorted by placing a cap across the two terminals.
restart pc and press f2 to reset time and date and save and exit, it should then boot back up.
If your problem continues to not allow you into the bios, the chip is faulty and you will have replace the motherboard.

This is only a stab in the dark but are all your M/board fixing connected correctly Hard drive etc. One other way is to disconnect everything from M/board except for Video and memory and try to boot up if it does then connect hard drive etc one at a time rebooting each time until it will not boot that is the wrongly connected one
"Also after I try to turn it on after a couple of unsuccessful tries, it actually boots and the machine works fine". This maybe cause by the hardware problem. And it usually caused by the motherboard. Changing the motherboard unit may solve the problem. But make sure you've already done the basic test on all of your hardware before changing it with a new one.
I bought the same motherboard this past year (used) and installed it with AMD Athlon 64 fx-57, Antec P180 case, 550 w power supply. I had the case cover off to check the fans when I first fired it up. The AMD oem cpu fan hesitated at power on for a few seconds, which worried me. It started spinning normally and I then shut the system down and waited a few minutes before restarting it. It spinned up fine so I put the cover back on. I started getting the same error you mentioned, so I updated the BIOS to 1013 version. That didn't solve the problem. I ended up disabling the warning in the BIOS as I got tired of seeing it, as I could see the fans were all spinning and the CPU temperature was at about 26 to 34 on cold boot.
I recently checked on this problem and seems many others with this board have this problem. One fellow said he mailed off a question the the problem to ASUStek and they replied that it is just a glitch, that the fan is "smarter" than the BIOS, as it will hesitate to spin fully at start up if the CPU is cool. The suggestion was to disable "Q Fan Controller" in BIOS. I did and don't get that warning.
As for the yellow question marks under manage in Windows, you need to install the drivers for all of those devices, and they will be on the disk that came with the motherboard. I use the latest drivers from the ASUS site, but the only one I couldn't install was the ACPI ATK 0110 Virtual Device that came out in 2007. When I try to unpack the .rar file it says Corrupt Headers and refuses to use the driver from that file. So, I use the driver from the disk.
The beeps you hear are probably BIOS error beep codes. Through a series of long and short beeps the BIOS communicates what type of error is occurring during the initial stages of the start up process. If you can tell me the manufacturer and model number of the board AND the sequence and length of the beeps I can point you in the direction to go.
