...Does anyone have any ideas?

Just an 'out there' kindof idea ...

How big is the new power supply you mentioned that you put in? If it's a ridiculously huge capacity it quite possibly isn't reaching its minimum loading (should be marked on the supply if so...) before it'll come out of standby [Mobo should be enough if functional though really]. A mobo, in some rare cases may simply not be enough... Try attaching the power for the hard drives (without data cables yet) and all the fans etc... that should be more that enough load ... do fan's etc even come on? [maybe I missed if it was mentioned sorry...]

Jason

[Later: a search of the corsair forums revealed the further (remote) possiblities that certain mobos, like ASUS M2N-SLI, in combination with high efficiency supplies, like Corsair HX 520, sometimes get a similar result. Posts suggested they have a 'staggered powerup' of components on the motherboard leading to not meeting the minum load of the PSU quickly enough. ]

No beeps...

Don't kick me but this one threw me the first time I thought I had fried an Asus MoBo.

You do have a speaker connected to the MoBo for the beeps to come out of??

"Time is simply the mechanism that keeps everything from happening all at once."

We all know that computers are tempermental beasts. This problem sounds similar to one I had last month. My father-in-law gave me his old system as it was playing up (not quite 3 years old).

On booting up, zilch, no beep codes & black screen. Wasted over a week trying all combinations to get it to boot. Said to hell with it, took a chance & purchased a replacement board(Asrock P4i65G). Put everything back, bingo, up & running. Sold system.

Kept the bad board (Asrock P4i65G) & played around with it during the holidays.
Rebuilt it one final time before I binned it & bingo, up & running. I checked everything out & the only difference was the ram. On the orginal I had a 1gig stick in - on this one, a 256mb stick.

Switched off & inserted a 1gb stick, rebooted, zilch. Now I know that the 1gig is okay as I borrowed it from my server. Put the 1gig back into server, working normal.

Put 2 512mb sticks into the Asrock, she's working. I have it running in my work area & if still ok after a week, will either add it to my net or sell it as a 2nd user system.

Might not be the same problem, but it's worth trying.

Heh I had a 1st time weird problem with a little sytem I was given.
An AMD 2800+ Sempron, Asrock K7S41GX Motherboard & 512Mb DDR.
Built it up, plugged in the 21" Dell monitor, switched it on, got the good old BEEP.

Greeted with a blank screen.
*puzzled look on my face*
switched off
Checked stuff inside, all ok.
Switched back on, BEEP, blank screen (repeat several times)
Got annoyed, and decided to switch to TFT so I could see if it displayed anything, as 21" CRT monitors take ages to display anything!

Thats when I spotted the problem.

"Secondary solo ATAPI device set to slave, for enhanced stability/performance, please set to Master. System will suspend in 3..2..1"

Yeep the CD/RW was set to slave and the system was not happy about it so it would not boot....

So if it's an Asrock board check that one, Never had a system with that stupid "refuse to boot" problem before...

I was recently given a computer by my brother after it died on him. It doesn't power on so I replace the Power Supply. It now powers on but I don't see the BIOS. So I replace the motherboard and CPU and it does the same thing, powers on but no BIOS. I look at my power supply again and notice I have these extra 4 pins next to the 20 pin power source. So I buy an adapter to convert the 24 pins to a 20 pin motherboard. It still does the same thing. I have a computer with similar memory and tried to replace that but that didn't work.

Is there something I am missing? Does anyone have any ideas?

There is at least one brand of motherboard that comes with a jumper set such that it does exactly what you describe. I have one and it took me a long while to figure out the problem. The one I refer to is a PC Chips. The jumper set is not described well in the instruction manual.

It is an older mobo model, PC Chips M811 LU 3.1 Socket A.

There may be others that do the same.

I will admit that I didn't have speakers plugged in when I tried to boot, so I tried that and it's the same, powers on but nothing on the screen.

The power supply is 450w, the old one was 400w.

Let me see if I can sum it up better;
With only the PSU, CPU, MB, RAM, and video;

Old board and CPU with on board video: Powers on CPU but displays nothing on the screen. Same result with or without RAM and no beeps either way.

New board and new CPU with graphics card: Powers on CPU but displays nothing on the screen. Same result with or without RAM and no beeps either way.

I did try RAM from another machine which works in that machine. Same result so I'll try a different video card and see where that gets me.

I had many instances of apparently successful boots with no display on two systems built on Gigabyte 965P-DS3 motherboards. It turned out that they like an extra 0.1V on the MCH (Northbridge) voltage to avert this behavior.

I have no clue why this might be, and not much whether it might have any relevance to your situation.

I can't find the name of the MoBo anywhere in this thread. Is it, by any chance, an Asus?

When I mentioned speaker, I wasn't referring to speakers plugged into the back panel. The POST beeps come from the internal speaker in the box.

If it's something I have to hook up for internal speakers then no. The only things to hook up are power button, reset button, hdd light, 2 front USB ports, and front case light.

Plug in the internal speaker (the case one), that will help a lot.
As the number of beeps the thing makes lets you know of any problems

Thank you for posting the MB and CPU. Are you aware that according to the manufacturers page here that the CPU you are trying to run in it is not supported? Do you have another CPU that IS on the list that you can try?

According to the spec you should have connection headers for:
1 x 20-pin ATX Power Supply Connector & 4-pin 12V Connector
1 x FDD connector supports two 360K~2.88MB FDDs
2 x IDE connectors
2 x Serial ATA connectors
2 x USB 2.0 headers support additional 4 USB Ports
1 x IrDA for SIR header
1 x SPDIF out header
1 x Speaker header
1 x Front panel switch/LED header
1 x Front panel audio header
CD in/ AUX in headers
CPUFAN/PWRFAN/SYSFAN connectors

I had to recover a case speaker from an old case to connect to my Asus MoBo. If your case does not come with a fitted speaker, you may have to do the same but a small speaker connected to the header is very useful in your situation.

If motherboard doesn't beep, and it's s775, try to remove CPU and look at CPU pins on MB. All of them should look same, see if anyone is curved. Another problem may be on dirty downside of CPU, Intel CPU-s are very sensitve...

Sorry for my delay but thought I would take a breath. I got another video card and still nothing. I had someone suggest what I'm using for this computer so here it is:

ECS 848P-A7 LGA 775 Intel 848P ATX Intel Motherboard*
Intel Pentium E2140 Allendale 1.6GHz 1MB L2 Cache LGA 775 65W Dual-Core Processor*
2 - DDR 400 1GB sticks of RAM
Raidmax RX-450K 450 Watt Power Supply*
nVidia GeForce FC 5500 256MB

*New parts

Since HDD and other drives don't matter, I didn't list them but they came with the computer as well. I don't have a speaker I can use for beep codes.

I really didn't want to build a new computer, thought I could salvage this one but that's my luck.

If I quote myself will you read it? Your CPU is not supported on that motherboard. Find a pentium D or pentium 4 and try it instead to see if it works.

Your motherboard doesn't support the chip you have...

If the RAM is bad / not compatible, it will just black screen.

I had a motherboard die recently I thought It might be the ram, So I put two other types of ram in(3 different Brands, OCZ(75 Error), Corsair(75 Error) and something called Add-On which is 1.8v ram 256k(7F error) that I use for testing) and I got the same error code out of an aw9d-max, I took the corsair ram, cpu(QX6700) and 850w OCZ psu, 36gb raptor hdd from the aw9d-max and put them all in another PC(the new motherboard is a ga-965p-ds3 v2.0 that I'd gotten back from RMA) and all of them are working just fine @ 3.2GHz, So the aw9d-max needs to be rmaed to Abit as I can't figure It out and I'd reset the Bios 3 times, 2 times the normal way and once deeply for an hour(No battery, Power unplugged and cmos clear jumper on clear cmos for the entire time, Which had no effect at all). It may have had a black screen but the video card and monitor are just fine. So the ram isn't always a problem. Oh and the aw9d-max Bios is just about as new as they come as It's 1.5B04 which I like better than 1.5 final, which sucks on overclocks.
