Won't turn on meaning

Won't turn on meaning you press the power button and absolutely nothing happens or you press the power button and some fans start running but not much else?

In addition to Bob's ideas, this is a pretty classic symptom of our old friend bad caps (google it).

Is this that old NFORCE system?
by R. Proffitt Forum moderator / April 20, 2014 2:16 AM PDT

If so, start reducing parts. An IDE failure along with all the usual can cause this such as a low CMOS battery.

Get out your Volt meter and tell me what Volts you read on the battery and all PSU legs.

PS. It's an old system and I'm making an assumption you repair PCs.

no its a biostar tforce4 am2 ver 1.1
by craigc187 / April 20, 2014 4:57 AM PDT

I have tried removing everything down to 1 stick of ram and removed the ide drives
Because i know the bios should still boot with out a hard drive

As for the battery i could not remove it and i did not want to break it

It's broke.
by R. Proffitt Forum moderator / April 20, 2014 5:29 AM PDT

I can't break stuff that is already broken. Also if you never changed the CMOS battery and this looks to be well over 5 years old, then it's a possibility.

As to BIOS, we can go for beeps. No RAM is needed for a board+cpu to beep in protest of no video card, ram, etc.

I dont see anything on this motherboard like a small speaker or leds is it possable this motherboard is unable to beep?

If it's missing the speaker we add it.

When it's that broke, we don't go for BIOS screens. We go for beeps. Keep in mind that THE DEAD PC is all over the web so I assume you use that if you are new to troubleshooting old PCs.

To flash the BIOS

In reply to: replaced battery

We never guess how. We head to the motherboard/system maker's site and follow their directions. I doubt it's a BIOS issue unless there was a prior failed attempt. I can't tell if you went for beeps or checked the BAD CAP issue and more.

Let others see what you see.

In reply to: ver 1.1

If I search for the motherboard support page I might get the wrong page. I missed where you shared that page so let's see a link.

And if it's not documented then we call the maker. Some don't like that but that's how the industry works.

Old parts or PC scenario
by Willy / April 22, 2014 1:28 AM PDT

Quick note, the fan spins for a moment then it stops? If so, then replace the PSU or Google bad caps as suggested. Next, a quick test is to unplug the AC cord, wait 15min. and return plug, try it then repeat but wait 30min. or overnight and retry. If it still won't start, then possible the mtrbd. is fried or broken in some way excluding other bad part(s). the point being, if as others suggested its 5yrs. old, then it saw better days and any repair in on you as well as cost which won't be cost effective. On top of all this having 2-IDE 40gb drives is really pushing it power wise and overall PC because these are dated too and thus time to move on. Understand, if you find a bad device, replace but the mtrbd. being so weak could take down any so-called new replaced(used or not) because it has been compromised due to wear&tear. You can play all you want, but dragging old parts foward has a price, they do break and may take something else with it.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
