PC is not booting!

[Akaz1976]

I have a P4 - 2.5GHz PC with 9800 PRO and 512MB RDRAM (detailed specs in my sig).

I usually leave my PC on 24/7. Today when i tried to 'wake' my PC it didnt work. My screen (DVI-D connection to Dell FP2001) remained blank. At first i though my LCD was screwed but as soon as i unplug the DVi-D cable it does the self diagnostic and it runs fine.

Next i thought that my video card might be dead but then i noticed that every time i reboot i dont get the 'beep' that sounds when ever my system boots up and also hitting 'reset' button doesnt reset the computer (i have to switch it on/off). So may be something other than my vid card is messed up.

How do i find out what part of my PC is damaged?

Does your motherboard have led indicators or beep codes for troubleshooting?

If your hard drive is not being accessed (hence, the computer isn't booting), then it's probably not a display problem.

ok it appears that my mobo is not posting. So the problem is with either mobo or PSU.

If its PSU then its a partial blow out (didnt even this could happen) cuz lights start up and CD/DVD rom starts.

Anyone know how i can reset CMOS?

Consult your mobo's manual or visit the manufacturer's website for instructions specific to your mobo, but generally the method is to power down / unplug PSU, remove the CMOS battery from the board, and possibly (depending on your mobo) momentarily move a jumper on your motherboard for 10 seconds or so. ie. move it from position 1-2 to 2-3 and then back to 1-2. then reinsert the battery, plug in and power up. hope this helps.
