Desktop powers on but no boot screen...

Microsoft Windows xp media center 2005

Specs: Windows XP
I had this computer for about 3 or 4 years; I didn't really treat it with care as I should have--turning it off manually, viruses, leaving it on for long periods of time; etc. About a year ago, it started acting weird, such as when I go to turn it on, it powers on but it won't boot up; it doesn't show the logo, desktop; etc. And I would have to turn it on & off several times until it fully came on. Now, a couple weeks back, it still does the same thing except now, even when I turn it on & off, nothing happens. The power light is on, the disc drive lights up & I can hear the fan running. Its not the power supply and its not my monitor--I recently bought a new graphics card & my ram is fine as well. I been told by someone that I need a new motherboard but I just think there's something on the motherboard that needs to be fixed & not buy a whole new one. I've done some research online & I seen some topics about BIOS & CPU, those seem to stick out to me. I'm not really a computer expert so I'm slightly confused about those two. I also cleaned out my fan but that didn't work either. Does anyone have any idea what could be wrong. It would really help alot. Thanks.

If i were you i would have gone for a complete format and a fresh installation......that should solve the problem.

Generally one does not replace anything on the motherboard itself with the exception of the cpu and I have not heard of that causing the issue you described. Normally this issue is caused by a power problem. Either a failing power supply or a bad connection or a warped or cracked motherboard. It is very possible for the psu to be bad and still spin all the fans and drives. They tend to fail in stages. The only thing you can do with the bios is to update it but if it does not boot I am not sure you can at this point. I would go over the motherboard real good and look for cracks or maybe bulging or leaking diodes. If you find nothing there then I would look at testing your psu. Either by use of a meter or putting it in a known working system. You could also try a known good psu in your system. Some may say that the cmos battery needs replacing but to be honest I have not yet seen a battery cause the problems you described but have heard that though.
