First Time Boot Failure

sid645 · #1 08-19-2005, 09:36 AM

Here are the specs first of all: ASUS A8N SLI Deluxe Mobo, Seagate SATA 120GB HD, GIGABYTE GeForce 6600 GFX card, AMD Athlon 64 3500+, 2 optical drives, 400W PSU.
We hooked it all up the first time and nothing happened. The power supply(Ultra PSU 500W) made this electric noise and then started smoking so we turned it off. I switched the PS with a 250W one, and it worked but the wattage was too low so the cd drives wouldnt work. So we got a 400W PSU and everything cuts on except for the monitor...it doesnt activate. We switched out video cards but it still didnt work. we have reset the CMOS including the battery, and have taken out the screws in case it was grounded.
Any Suggestion

look at ur motherboard manual and see how much watts it needs.

At least 300W.

I'm having the exact same problem. This link gives a list of a couple things to do, however, none of the ones I've tried so far have worked for me. If anyone knows the solution to this problem or if you find out what's wrong, I'd greatly appreciate it if you could share it with me

Thanks.

All right, I just finished scanning through the last 50 pages of this forum. This seems to be a very common problem for first time users, so we shouldn't despair too much.

What I found out was that a failing PSU is the main cause of a boot failure. Even though I probably went through 30 or so different threads where there was no resolution for the problem, 4 or 5 people claimed that replacing their PSU worked for them. One person claimed that it was because their motherboard was defective. One person claimed it was because their RAM was defective. I think I'll be ordering a new PSU soon.

After seeing all the horrible posts about the possibility that my motherboard/cpu/ram were dead, I was becoming extremely worried and resigned to the fact that I needed a new PSU. Then I saw somebody on a different forum suggest making sure I had plugged in the square 4 pin connector close to my CPU. I hadn't. Sure enough, that's what fixed it for me. Hopefully your problem is as easy as that too

It is highly likely something was damaged during the burn up.
Does the PC make any noises at all? Is the HD spinning?

yes....HD is spinning and everything

Without being able to test it myself, I would say it is possible the board is fried. Or the CPU possibly.
Do you have another board to test the components?

How do you mean video wont come on? does the system actually post and try to load windows and its just the monitor doesnt switch on, or do you mean that as he suggests, the mobo is probably dead, or the CPU, and it doesnt even post. Do you get any bleeps at all?
