Computer Turns on But doesnt start

Okay im gonna try my best to explain this problem.

Okay my computer turns on, like everything is on fans are spinning etc. Problem is thats this is as far as it goes, doesnt go to the boot screen where the window xp loading thing is and the mobo screen. my monitor isnt even on, so is my keyboard/mice.

it was working properly earlier today. Happened few times during today but it worked after i pressed reset button not it doesnt even seem to work.!

Btw this computer is around 3weeks old.

specs
cpu-e6850 3.0ghz
gpu 8800GTS 512 in sli
case is antec 900
PSU 750watt silverstone sli ready
hdd samsumg 500gig
msi p7n sli platium nforce 750sli

And you forgot to mention your motherboard.

I built a machine with the E6850 not too long ago for a friend of mine. Even though a lot of times to the motherboard says it supports the processor, it doesn't. What you need to do is flash your bios to get it supported, or get another motherboard in case it doesn't support it at all.

Post your motherboard please.

If it needs flashing, you're going to have to take it back to where you got it and tell them to do it for you, because I'm sure you don't have a random processor laying around that is supported so you can flash the bios and put the other processor back in.

msi 750sli 12char

Wolfdale E8400 (3GHz, C0, 65W) 1333 9 SINCE 1.1

You probably need to flash your BIOS to version 1.1.

it was working for 3 weeks, how come it just do this to me now o_o?

I guess I read the post wrong, I'm tired :P

*goes back to thinking*

come on u computer gurus out there! i nid help T-T

Be sure your monitor is firmly plugged into your video card. If you hear a sequence of beeps check the motherboards manual to see if it refers to error codes. The motherboard will beep differently for memory errors, cpu errors, etc. Also be sure your video card is firmly in the slot. I had a problem similar to yours several months ago. It was a dead video card, but it had showed signs of dieing before.

no beeps happening here.

sounds like your video card mine did the same thing when my card died make sure its in its slot firmly,if it is and u got a video output on your MB take out the card and put the lead in the MB

hmm, im on sli atm i did reboot with the DVI pluged to the second video card same result.
And i highly doubt its my video card, was playin cod4 today and it was fine. No artifacts, avg temp was 57 on load both card.

System is new just took a look inside and no dust lying around.
All cables connected correctly no loose ones.
With my mobo i have a button to reset the cmos, pressed that nothing happened.

One sad sad night for me. QQ

It's most likely a hardware problem. My guess would be your CPU is malfunctioning/damaged/fried. Check/Replace CPU or RAM.

Basically it's up to you to check your hardware components.

Ah yea one thing i did do was update my driver to the new nvdia one (cant remeber the version) though the computer Did boot after the instalation. this was rougly 2 days ago.

So the Nvidia driver decided to leave you alone for 2 days before screwing you over somehow?

Does your PC make a "beep" sound when it normally started?

Edit: Just to clarify your POST (simplified: your PC starting up) is not effected by any software (excluding software that alters the BIOS) you install on your computer, this includes drivers.

Nope no BEEPS!!!!! i dont think anything fried up no burning smell, i always monitoring my cpu/gpu
cpu temp=22c-32c (onload)
gpu 45-57c (onload) (fan on 40%).

There's not much other than hardware failure that would cause your computer not to boot. Not all damaged hardware leaves a smell.

Hmm i also find that my power cable to my powersupply is rather loose. Will this be the problem?

Unlikely since your fans etc all turn on. Your PC needs 4 thing to boot: PSU, CPU, GPU and RAM and you'll need a working screen to display this information. Check these 5 components.

hmm..Im not really an expert, How do i check =)?
i only tried smelling so far XD seems fine.
i was told if it was a ram problem it would beep>? no beeping here so can i rule that out?

Best way to check is by replacing these components with other functioning components i.e. replacing each component with a working one and seeing if the computer boots. Or using each component on a working computer. If you don't have access to spare parts, the only other thing to do is bring it to a computershop to get fixed.

Bringin to the computer shop is my last resort, i dont think this is a major problem.
THe computer DID turn on when i pressed the reset button before. BUt now this trick isnt workin anymore. This makes me think that its not much of a cpu/gpu issue but maybe the mobo?

edit/ i also raned a 3dmark06 benchmark yesterday? does this screw it up o-o?

no beeps = no post

in a working system you will get 1 short beep.

In my experience, start as basic as possible. power supply, 1 hard drive, minimum ram?( 1 stick in the 1st slot), monitor, keyboard and mouse. fire up the comp. do you get a beep? If no, then move to step 1. If yes, move to step 2.

1. no beep = now its time to remove the CMOS battery, it looks like a giant watch battery. UNPLUG YOUR COMPUTER, remove battery, hold down the power button for 15 seconds. put battery back in, plug comp back in. power comp up.

do you get any beeps? If so how many and is there a pattern. Does it sound like moaning demons? does the power supply fan come on?

2. getting 1 beep w/ minimal hardware. start adding in 1 piece of hardware at a time until it fails. What piece causes the fail? This will prob need replaced. but then try to boot with just that piece does it boot?

It really sounds like your video card is dead, as I said before I had similar problems before. I had to press the power button a few times to get the computer to boot with anything on the monitor. As Dark kail stated, theres only a few hardware things that could be causing you not to boot. You can test the cpu and memory by removing them one at a time, you should get a bios screen stating that one of those are missing. CPU is usually the least likely to be having problems. I would check to see if the video card is firmly seated in the slot by removing it then putting it back. The same for the power going to the video card (if the video card requires it) But either way unless its something loose its a part that has gone bad.

I'd take it to the shop first. Since you're inexperienced with computers I'd let them take out the CMOS battery, so if they screw it up they have to pay for it. You, by accident, may make the problem worse by playing around inside the case.

A benchmark may have caused a hardware failure, although this is rare. Did you run a "burn in" test with the benchmark software? Or just a simulated burn in?

No it probably didn't screw it up, but might have stressed the video card enough to die, which it would have in the near future anyway. Its usually a good idea to run stress tests on a new computer anyway, the earlier you detect a failing piece of hardware the more likely you get it replaced for free.
If you don't feel comfortable removing parts of a computer get a local computer shop to do this, they probably wont charge much more than $50. But as as long as your careful, remember where everything went when you removed it, and discharge static electricity its not hard to work on a computer.

Your PC not doing anything but turning on the fans and pretty lights constitutes as a "major problem". A benchmark might have brought on the hardware failure. Mobo issue is also possible although unlikely. It's impossible to tell what part is failing without the details.

Your best bet is a computer shop at this point.

Agreed.

hmm the cmos battery is right underneath my gpu, i have a feeling its my HDD i put my finger over it not much vibration..both gpu fan still spinning not sure about the inside though. I still dont think its my GPU cos i was playin cod4 and its all good!

Nope, you can boot without a HDD installed.

Yeah, your HD shouldn't vibrate noticeably. And it will boot without it. But it won't boot without graphics.

But we've basically ruled those two out, since there are no POST beeps.

2 cent did you try my suggestion(s)?

Try clearing the CMOS first. It's similar to what they were saying about removing the battery, but not as drastic. There should be a jumper near the battery that you move to clear the CMOS and then move it back to where it was (Check the manual!)

Next, make sure that all connectors on the mobo, drives, etc, are fully seated. Sometimes it helps to unplug them and plug them back in. Make sure the video card is fully seated in it's slot.

If that doesn't work - start with the most basic:

Un-plug everything from the mother board - except the power supply connector and the speaker (if it's external). Remove all the cards, including the video card. Remove the RAM. That is, you should have nothing on the motherboard except the cpu (with heatsink&fan) and the power supply connected and the speaker (if external - some mobos have a small spkr on-board)

Since you could even have a bad power switch or reset button (and you disconnected those too, right?) - short across the power switch connector with a screwdriver (or whatever) (no shock/short hazard). The power should come on and you should get a bunch of beeps (telling you there is no RAM and/or video present.)

If you get no beeps, it comes down to bad mobo (or BIOS settings), bad cpu (or BIOS settings), a bad speaker (no likely), or a bad power supply.

If you do get beeps, plug in the RAM and try again. (Turn it off first - duh) You should get beeps telling you there's no video card. No beeps = bad RAM.

Next you can plug the power switch back in to make things easier and install the video card.

With the video card installed, you should get a single beep when it starts up, indicating it passed POST. If not, it could be a bad video card (or power switch stuck on)

If it works, continue plugging things back in (powering off in between - duh) until it stops working. At that point you will either have found the bad part or found the point where the power supply craps out.

Happy hunting.

Really important step here... or you won't hear any beeps at all. If they're external speakers, make sure they're hooked up to the audio output at the back, plugged in, and turned on. If it's a case speaker, make sure it's connected to the correct place in the front panel header area.

Umm, you are using an MSI board. It is highly likely that the flash system corrupted, which can temporarily corrupt the Core system that MSi uses.

Reset your BIOS/clear the CMOS. While the PC is off, directly above the battery (north) there is a small round button. Press and hold it down for 10 seconds. Release the button, and restart the system. If the problem persists, take out all the components except the graphics card, power source, RAM, and CPU. If it doesn't boot at that point, remove the RAM. It should give a beep code of approx 6-8 beeps, typically 8. If this is the the case, put back in ONE stick of RAM. If it fails to boot again, alternate each stick of RAM until you have tried each one alone in DIMM slot 1.

If it fails to boot each time, then either your graphics card is dead, or all of your RAM is dead. The next step would be to remove your CPU. However, these issues get too complex. If your motherboard (I couldn't tell from any high-res reference pictures I tried to pull off our server) has a POST CODE display LED system (it will be a gray box that displays a two digit (alpha numeric) code according to the POST status) You should find it near the CoreCell system chip, above the battery. Just look. If it does, tell me the code you are seeing (that last one it displays during the boot you are "not seeing")

took out the rams no beeps =x

And the video card?

havent taken it out yet goin back tot he shop soon. Anymore solutions b4 i go back tot he shop Oo? Sumthing less practical.

Just make sure everything is back in place properly before it goes back to the shop

"Sumthing less practical"? Surely more practical!

All you have left to try is the one thing you haven't tried: Removing the graphics card. Since it's going back to the shop anyway, you might not bother - but hey, it could save you money.

Hmm i did try taking out the SLI bridge last night , though same result.

mobo is broken
