Need some help please - no display when booting

Hey guys, new to forum and would appreciate any thoughts on my current situation...

My problem is that when I turn on my pc, I get no display at all. This started yesterday without any warning. I had the pc on for a few hours in the morning, powered down & later on I tried to power-up and got no display at all. I tried a different monitor, different v-card, mouse (non-wireless), keyboard (all are known to be ok) - no luck! When I power-up, all of my fans (case, processor, power supply and v-card) start, my harddrives run, my optical drives have power (can open & shut the doors) but I just don't get any display at all. I also don't get any sort of post beeping. I pulled out my RAM (RDRAM 4x256) just to see if I'd get any error beeping, but I don't get anything. I removed the battery and reset the cmos, I even bought a brand new battery and installed it. I re-seated the proc, but that didn't help. One curious thing is I don't get any lights on my keyboard, nor do I get a light on my wireless mouse receiver. I'm thinking something has gone wrong with my motherboard - that's the only component I can't swap out with my parts on hand. I was thinking the PS was bad, but I get power to everything in the case. The PS is a Chieftec 420w. This is kinda frustating - it's my son's PC and I am known as the one who can usually fix anything PC related, LOL! Any help would be greatly appreciated. Listed below are the pertinent PC specs:

MB: Asus P4T533-C
PROC: Intel P4 2.8 ghz
MEM: RDRAM (4 x 256mb)
V-CARD: Nvidia 6800GT 256mb
HDs: Maxtor 80gig EIDE x2
OPTICALs: Liteon 52x CDRW, Pioneer DVD-R 4x
PS: Chieftec 420w
SOUND: Soundblaster Live 5.1

Once again, thanks in advance!!

Edit: OS is WinXP Home

Troy, do you have a multimeter handy? You could check the voltages going into the motherboard and see if all of them are there and at the right levels.

If you aren't posting, then the cause of failure is limited to the PSU, motherboard and processor.

No I don't - wouldn't know how to use it anyways, lol. On a couple other forums, people think it may be the PSU, but would I get power to all of the other components (which I seem to be) if the PSU was dead or dying? Thanks!

Well sir, dude, mr dude:P

I had the same problem. Tryed everything that was possible, First It ran and hang once in a while. Then it didn't start anymore, and when I got screen It stopped running.



If you got a other (Same socket) Processor, try if that works. This way you know if it is the processor or the MB. I did this and I now know I have to get a new MB (tryed the proccesor on a other MB and worked fine.


good luck!
