Any computer wizes on here?

[Ninjabread]

Ok, have to find out what's going on with my desktop. It was running fine this afternoon, I was playing some games, browsing zilvia, etc.

I get back from class tonight, hit the power button and this is what happens.

The fans go on, the hard drive spins, but thats the extent of it. The power light on the front of my pc does not come on (it did this after noon), and it doesnt seem to be sending a signal to my monitor (it's on standby and nothing happens.

Now, I have taken apart and redone all the cables, so I'm pretty sure I've eliminated loose cable as a possibility. I've also tried another known working video card, with no effect.

If anybody has a clue... help!

cpu might be overheating

make sure your fan and heatsink is secured along with the paste you put on the top of the cpu

[Ninjabread]

Hmm, whats weird is that the pc is cool now, it hasn't run for at least 5-6 hours.

Ok, i even took out the fan heat sink, cleaned it all, put it back together, same thing.

[lflkajfj12123]

computer will still not boot properly if there is something wrong with the cooling

its a preventative so you don't burn your shit up

[mrpeepers]

did you check if your power supply is fully functional?

[superbovine]

can you window start up sound?
If you can try and new monitor.

If not try this:

pull out all your memory and turn on the system. if you hear beep codes you motherboard and cpu just has passed the start up test. if you did not, the motherboard and cpu failed the start up test, and are probably bad.

Did you recently change the refresh rates on your moniter?
I know if you change them for gaming, you get a better FPS..
But sometimes if you change them.. and reboot your moniter wont be able to handle it, so it doesnt even turn on.

You may be able to borrow another moniter, and fix your refresh rates.. then use your regular moniter..

I hope that makes sense.
GL with it tho.

Just pulled out all memory and turned it on, no beeps.

Guess its time for a new pc.

bad psu or vid card

[Ninjabread]

Yea I'll try another power supply see if that doesnt do it... Although it does have an antec 380w, which should be good, but who knows.

Video card has been ruled out.

Your computer would turn on even if there was an overheating problem, it just wouldn't stay on very long unless it already burnt itself up.

Try disconnecting everything except the power cord and monitor cable and see if it boots. If so, it's one of your peripherals preventing it from booting. This happens often when USB devices or keyboards/mice go bad.

Perhaps even try disconnecting the monitor cable and see if the power light on the tower comes on.

Basically just try eliminating as many things from the equation as you can to get to the real problem.

Also, if your PSU was bad, it's highly unlikely that anything would work at all.

[Ninjabread]

Tried that too, same difference.

I've already started looking at what I can salvage as far as parts and I'm making a bugdet to refresh it.

I was talking to a friend of mine who says it is most likely the motherboard, and after doing everything to test the computer, i'm pretty sure thats what it is.

[aznrib]

What are the specs of the computer? It is possible it is either the PSU. It would depend on how many watts it is and what other components you are running.

[emersonLP]

+1 for toasted motherboard. Definately sounds like it. If that is the case, you can salvage pretty much everything else as long as you get a compatible motherboard for your set up. (uses same processor, same type of RAM, same type of video card (PCI-e or AGP probably), and same hard drive (IDE or SATA probably) specifically).

Depending how old the computer is, it would be a good time to get a new mobo with PCI-e video card slot and replace everything that is necessary if thats possible for you financially.

I recommend ASUS for motherboards. Stay away from Gigabyte brand.

You pull the cmos battery?

[Ninjabread]

No clue what the cmos battery is. I'll try it if you give me a hint.

As far as salvaging, my motherboard is a asus k8ne dlx and it uses socket 754 which is pretty much obsolete, plus it only has agp ports. Processor is a amd 3200xp 64 bit, which is getting old.

I could get some new memory, cpu, vid card, and motherboard for less than 600$ to rebuild it up to decent spec.

[aznrib]

hm i didn't read you other posts. If you already tried another PSU then it would more then likely be the mobo. If you bought it less then a year ago then you can warrenty it. Depending on what board you have, some companies offer a 3 year warrenty.

battery about the size/shape of a quarter or nickel on your mobo, take that out, ground the 2 pins together, then let it sit for about 10 mins and then put the battery back in. Should reset your bios to default settings, if thats whats causing it.

[S14DB]

The watch battery on your mobo. unplug, pop it off, try to boot, put it back on, plug in, boot.

[Matej]

So have you tried a different power supply yet? If not I'd still recommend trying out a higher wattage psu if you have access to one before messing with the motherboard, even if the drives still spin. I don't know how new your video card is but you said you played games and most of today's video cards will kill a 380W psu.

+1 on the cmos battery check and see if it still has juice if not get a new one

[jrmiller84]

If your CMOS battery was dead you would lose your boot configurations and the time would be reset but it should still, at the very least, turn on and show you the boot screen. The computer should run the POST (http://en.wikipedia.org/wiki/Power-on_self-test) even if the battery is dead. It may not boot the OS because the boot configurations would be gone, but like I said, it will show you the initial boot screen.

The battery is used to provide enough juice to retain settings like boot order, power settings, device settings, time, etc between boots when the computer is not being supplied with power from the PSU.

By all means replace it though, it can't hurt. Just giving some insight.

[Ninjabread]

Replaced, no difference.

[UNISA JECS]

I had this happen to my older computer and it was just the AGP video/graphics card, bought a new one and everything was fine.

[Ninjabread]

I've already tested the video card. I'm pretty sure the motherboard is fried.

Yes but I've had some flash cmos go corrupt in their settings due to power fluctuation's. giving the same no boot.

This sounds like it is a fried board , if it was the psu nothing would get power.
