'No Signal' monitor...

I got my old PCI card and installed it, with the same problem. Does this mean it's not necaessarily an AGP/PCI slot issue? Everyone else I talk to insists it's something to do with it failing the POST check, and most likely something to do with my ram or the new heatsink I installed.

I called up ASUS's tech support, and he said the long beep means that it's not passing the POST check, which COULD mean a faulty AGP slot, but more likely because of something I did to my ram or CPU when I installed the new heatsink (like you guys suggested). It could also be a voltage issue. He said that if you use too much thermal grease, it can act as an inductor (or conductor? I don't know my electronic terms too well), and that may be interfering with something on the motherboard. He suggested removing the thermal grease with some rubbing alcohol, and try all of my compnents (such as videocard, ram, etc.) on my buddies computer just to make sure they all still work.

Any suggestions/ideas?

It's kinda unclear...did you, (the original poster), have ANY heatsink attatched to the CPU when you powered-up?

EDIT: I just built a socket A system,m (last week), that would not post because I had the USB port improperly plugged in. Try putting tose jumpers for the audio back where they were. Sometimes motherboards, (at least in my expeirince), can be very tempormental over little crap like that.....and it WILL piss you off....trust me....

Well? How did you do it?

Not sure if this will help or not but had the same problem with a computer a few days ago. The guy had bought new memory for his computer and said that it would no longer boot up. It would try to boot and had the long beep.
He had 4 memory slots on mboard...slot1 & 2 had the new mem, ,and slot3 & 4 had dummy cards installed. I took all mem cards out, replaced old cards back on slot1&2 and then put new mem on slot3&4...took the dummy cards out.
Like I said, this may not work, seemed too simple of a solution to me...but it solved my prob.

Yeah, I did. Sorry I didn't clarify that before.

What I meant when I said I tried booting up the computer without the heatsink attatched, I meant I tried it once, and only for like 3 seconds. I instantly turned off the computer and put the heatsink back on, and it's been on ever since. The only cord that is attatched to the heatsink is a 3-pin cord that goes into the motherboard...unless there's another cord that I may have forgot about in the box at home for it?

I hope this is not the case, as then I would need to go out and buy a whole new stick of 1 GB ram! Is it possible that my stick of ram may have gone bad as I took it out of the mother board as I switched it into the new case? Would a way of testing this out to see if it simply works on my frineds computer (assuming the ram is compatible with his type of motherboard)?

The only reliable way to test RAM is with a mem test. Gimme a minute, I'll dig up a link.

memtest would require that you have a computer that will actually POST, so you'd need to plug the stick of memory in a computer that is working. if the POST error doesn't let you start the bootstrap process, and it is the memory causing it, then memtest isn't even necessary.

ok, so the question is if you have just the one stick of memory. if you have 2 sticks, try booting with one in and then the other. if you only have the one, try to find another somewhere to see if changing the memory does allow the board to POST.

your processor probably suffered no damage from powering on without the heat sink since it is a pentium 4. not only will the processor protect itself from damage, it will actually continue to run, though with severly reduced performance, without a heat sink attached.
