I have a system based on an SY-K7V DRAGON Plus motherboard (VIA KT266A chipset).
Yesterday, I got some weird program exceptions and decided to reboot the computer to see if that would clear up the problem. I have never gotten back into Windows since.
At first, it would get through the initial checks and prompt me about whether I wanted to go to safe mode or load windows normally. No matter which choice I made, the next thing that would happen is that there would be a flash of a blue screen (it was so short that I could never read what it said) and the the computer would reboot again.
After a couple rounds of that, it now won't POST at all. When I apply power, fans start running, optical drives spin up, there is a little bit of hard drive activity, but nothing comes up on the monitor and eventually, it all quiets down except for the fan. No beeps of any kind.

Hi:) Turn the computer off but leave it plugged in so you have no static problems. Open the computer tower and on the motherboard near the Cmos Battery there is a blue or red jumper that covers 2 of 3 pins move it to the other side of the 3 pins for 30 seconds then put it back that will reset the bios to default.
might be a faulty connection/lead make sure they have secure connections
test all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your motherboard to hard drive also cd/dvd/3.1/2 inch floppy drive leads hope this helps

2 beeps = memory problems. Since you get them even after the memory has been replaced then the problem is in the motherboard itself. Check the capacitors for bulging. If you can't find ones or you can't replace them then the motherboard is dead.
