After ceaning dust in case machine won't start. After pushing power button, all LEDs shine normally, CPU and other fans works normall, HDD LED shine continusly, there is no beeps and other sound, resetting CMOS (by jumpers and by removing battery) doesn't work.

Your CPU fanmay be faulty and not spinning freely, in this case replace the fan. Check the fan and heat sink assembly and remove the dust, loosen the dust anduse a can of compressed air to clear away the dust.
When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail. A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust. Check the CPU fan to see if it spins freely, if not replace the fan. If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a can of compressed air to do this.
While the computer is running - inspect the visible fans. Make sure they're running smoothly - a screeching fan is not spinning at the correct speed - and like those not spinning at all; isn't doing the job intended. Replace any fan that makes noise or does not spin freely or at all.
Shut off the PC and take note of plugs & jacks; and disconnect all cables.
Remove the computer to a table with ample room to work. Position the computer so that left removable side panel is facing up. Loosen (or remove if required) any screws, clips or other fastener used to secure the panel to the case. Remove the cover and set aside.
Using a crevice tool or narrow wand attachment on a vacuum cleaner, gently vacuum the inside of the computer case. Try not to touch any components inside. Gently move cables and wires out of the way to allow the vacuum to **** dirt, dust, etc. from the motherboard and interior of the case. Some plugs at the end of wires can very easily be pulled off of connectors to the motherboard, so be very careful moving the cables and wires out of the way.
Be sure to pay attention to any slots in the case or drives - such as a floppy disk. Vacuum dust from the the opposite direction they entered - pull it back out instead of pulling it all the way through. Check openings in the case designed for airflow. Clear any obstructions found. Inspect the power supply. Often, a fan blows outside air into the power supply - coating the insides with dust. The dust is often visible choking the slots of the power supply inside the case - this should be vacuumed away from the slots, to restore airflow.
Inspect the CPU fan. Remove any dust and dirt caught on the fan blades. Spin the fan by hand. It should spin freely. Shine a light through the fan to view the heat sink. the heat sink is just a large metal piece that sits between the fan and the CPU itself. It conducts the heat created by the CPU away from the CPU - where the fan blows comparably cooler across it, wicking the heat away. If the heat sink fins, posts, or channels are clogged or coated, the CPU fan should be removed and the heat sink vacuumed or bushed clean in place. The CPU fan usually held in place with 2 or 4 small screws. Remove them and the gently rock the fan from the heat sink. Move it just off to the side so that it won't need to be unplugged from the motherboard. Clean the heat sink and reassemble.
After removing as much dust as possible, reassemble the case and reconnect. The overheating problem should be resolved. If you're still having issues, you start over again but this time try blowing the dust out. A caveat of that is that it forces dust and dirt deeper still into components inside the case. If the computer is not working - this may not be a cause for concern. It would be best to use a "shop air" source - like those compressors found in workshops or gas stations as they have large the large volume of air at significantly high pressure. Canned air bought in stores can't come close on either of those two qualities - but is better than nothing.
Reassemble and try again. If it is a heat related problem that hasn't existed long enough to cause permanent damage, your PC should work fine once again. Please rate this reply "very helpful" and good luck!
Believe it or not, clearing the CMOS might actually help. Make sure you do it right by completely unplug the power cord or turn off the PSU, then take the battery out.
It also sounds like the CPU might be too hot. Look under the fan of the heatsink and see if there is any dust that will block the airflow. When the computer is on, touch the heatsink and feel if it is really warm. If it is really warm, it's a good sign, you might just need more airflow. If it is cold, you might need to reinstall the heatsink/apply new thermal compounds.
If all the parts of your computers are fined functioning. This is a CPU problem witch is no display. Try to disassemble the CPU remove the heat sink the CPU and clean and insert it again. When you are now inserting the CPU be sure that you will put a thermal past in the heat sink so that the heat from the CPU are absorbed. If the heat will not be absorbed it will cause overheating.
Experience a similar problem with a FIC MB. I cleared CMOS then removed MB battery for 1 hour. Restarted the unit with just the video card and hard drive installed. After unit rebooted I added sound card, network card, etc.
You should always try a new power supply if possible. After all, it is one of the most likely components to fail - it's got moving parts (one or more fans), just like your hard drive (spinning platters), one of the other most likely parts to die.
That said, in this instance it probably is the mobo. FIC made great motherboards, but they got out of the business so you won't find the same one anywhere. If you have to replace it, you may be able to get out of a Windows reinstall by getting a motherboard with the same chipset, which looks like a 915/G, though any 915 based board might do. You may still need to do a repair install, but in many cases the same chipset allows you to boot and then just load all the new different drivers for the new board.
