Whenever i turn on my computer, it wont even load onto bios...
it makes a beeeeeeep... beep beep sound and stays with a blank screen.
im preety sure this is to do with the motherboard as it should at least load onto bios.
any help would be much appreciated.

unplug power cod, open computer Cabinet panel, remove cmos for 2 min and reinsert cmos,
wipe graphics card socket, reinsert graphics card, TURN on computer, press f2 to load default setting
you do not need to disable onboard graphics. in bios, some bios default configure your graphics card to primary
Test the PSU. Unplug it from the motherboard and then with nothing connected, short the green wire to any ground (usually a black) using a paperclip and it should come on and stay on if the problem was with the motherboard/computer but if it shuts down, then you know the problem is the PSU itself.
If the PSU stays on under no load, then one possibility is you had too much connected to it and it shut down as a protective feature. The Bios would not beep if the PSU is shutting itself down. Also make sure you have the internal speaker connected. It's possible you just can't hear the beep because there is no speaker connected or it may be connected to the wrong place.
Don't throw away a defective power supply. It is worth a couple bucks as parts for an electronics enthusiast. Keep it out of the landfill.
toddzr2 - whenever I have a problem like this, you need to unplug all your peripherals, i.e. take out your video card, unplug your hard drive, CD/DVD, etc. Power up, you should get some beeping b/c the video card is out. Power down, reinsert your video card, power back up. See if you can get to your BIOS screen. It's possible that something may have shorted out, i.e. video card, or other peripheral. Don't be afraid to remove the memory as well but make sure you're touching the case to keep yourself grounded and minimize any static discharges.
make sure it is not getting really hot, also try cleaning all again and start putting them together step by step. make sure the dust didn't got in another part like RAM memories slots, and if you have a big problem with the processor the PC wouldn't even start, wont even turn on.
If it beeps and not boot then it is the post routine telling you there is a problem. The post routine is run when you turn the power on to ensure the computer hardware is ok to run. The manufacturer of the bios routine can tell what is wrong by the type, number and duration of the beeps. Look up the code meanings and it will indicate the problem. If this sounds like nonsense to you then give the make and model of your machine and what the beeps sound like. ( beep beep beep delay beep beep beep) etc. and I'll look it up for you.
These sounds are known as BIOS beep codes. They indicate an error with your system. Traditionally, 1 long and 1 short indicates a system board problem. If you google bios beep codes, you will be able to find the codes that relate to your Bios, or motherboard. Backup your files. Your computer is trying to tell you something.
I have the same problem, the CPU fan spins, keyboard lights blink, no start up screen, or bios. But, when I push a few times on the pc reset button, then the CPU fan is becoming still, the keyboard light are out and I can start the computer again in a normal way. Can this one be a temporally solution for you too? Do you have any suggestion about? I guess it can be an electricity dysfunction of a wrong fixed cable.
