Computer Will Not Turn On

[w1ksz]

I have a Shuttle SH61, i5 Processor, with an FH61, Ver. 1.0 MB.

When I hit the power switch, the blue power indicator comes on
briefly (< 1/2 second) and then goes off.

I checked the power supply using one of those universal power
supply testers you find on that auction site, all voltages look OK.

If it's the MB, are there any hints to isolate the problem ?

Thanks for any assistance,

Regards,

Richard S

Welcome to the forums, Richard.

The symptoms indicate a short circuit on the motherboard or some component.

1. Unplug and reseat the main power connector from the PSU to the motherboard, clean the contact pins on the motherboard and reseat the plug, and try to start the machine.

2. Unplug power to all unnecessary components (hard drive, DVD, etc.), and try to start the machine.

3. Unplug the RAM, clean the contacts with alcohol and a Q-tip, and re-seat it. Try to start the machine. If more than one RAM stick, try one stick at a time.

4. If you're using a separate video card (not the onboard video), unplug, clean and reseat it as above.

5. If the machine starts up after reseating components and connectors, reconnect the drives. If it continues to work, reseating everything solved the problem. If not, try one drive at a time.

If none of the above steps solves the problem, the motherboard or one of its components may have failed.

Hope that helps. Good luck.

I pulled both RAM Sticks, dis-connected the three drives and pulled
a Serial Port card I had installed.

Now, it just cycles on and off ... on for about 1/2 second, then off
for a second or two, then the cycle repeats.

Thanks for the reply,

If it's not the CPU, itself, it sounds like your motherboard is dead. You could try contacting Shuttle's technical support or a local repair tech for further help.

If the board is dead, but the CPU, RAM and drives are good, you have a flying financial head start on a new system using components of your own chosing. It's even better if the PSU is rated at 500 watts or more and is in the standard ATX format.

All you need is a new motherboard, case and video card (if not on your new motherboard). You may be able to find some decent components for around $100 - $150, or even less, depending on your requirements. If nothing else, that will give you an idea of a limit on how much to spend trying to fix your current setup.

Again, good luck.

Considering the Local Tech Shops charge $50 to do less than I just did,
that route seems not to be the most financially sound route.

I checked e-Bay and did a Google search for another FH61 MB. Came
up empty.

Looks like I got a lot of good parts unless I find another MB somewhere.

Thanks for the assistance,

If you're not a skilled tech, once you get past the basic stuff, it may require a qualified technician's time to diagnose a deeper problem to determine whether or not the problem can, in fact, be repaired. Their time and skill are what they have to sell to earn their living.

However, as we discussed, it does set limits on how much you should spend. As in this case, the answer may be that it's less expsenive to replace it than attempt to repair it.

Very possible. The good news is, you're at least 2/3 of the way to that machine with the parts you have.

The better news is, you showed up on one of the best and friendliest forums on the planet for good info about the parts you have and help selecting the rest of what you need to make the most of what you have.

To help others help you, make sure you have the model number of your I5 (LGA1155) and the speed of your DDR3 RAM (DDR3 1333 MHz). For example, here are the specs for Shuttle SH61, Rev. 4.

That 250 watt PSU really isn't strong enough for your components. In fact, you may want to test your system with a known good, stronger PSU - at least 450 watts. If it's failing under load, it may still have tested OK with a simple teste while failing under the actual load presented by your systerm.

If your machine included a copy of Windows licensed specifically for your machine, you will still need a new copy of Windows because the license won't transfer to another installation. If it's retail copy, you'll be OK, and a generic OEM copy will probably work on another motherboard.

On the bright side of the down side, if you need a new copy of Windows, at least you'll have a good reason to do a clean installation of Windows 10.

If there was a source of Service Info (schematics, voltage points, etc),
I could run some tests on it.
I am thinking it's one of those high grade electrolytics that has bit the
dust. But, without any info, I would be just shooting in the dark.

So, it's off to find a replacement MB, or another i5 or i7 box.

I thought I would visit the Sale/Trade section of this forum, but I get
a message that I don't have permission ???

How does one get permission ??

Thanks,

To deter "drive by" spammers and fraudulant traders, new members cannot send or receive PM's, except with our moderators and administrators, until they have posted 25 messages on our forums. Sorry for any inconvenience.

When I recommended checking our other forums for info about good choices to make best use of the good components in your failing system, I was thinking you should check our General Hardware, Motherboards and CPUs and Overclocking forums to find the best matches.

Finding good prices is much easier once you know exactly what hardware you want, whether it's new from a good vendor or used on our For Sale/Trade forum or any other trading site.

It's pretty much academic now. Shuttle got back to me on a replacement
MB, a whopping $60. Not worth the pain to look elsewhere.

BTW, the two MB's I saw on e-Pay, one in Ireland, the other in Australia,
were significantly more money.

Thanks for the replies,

Richard,

I was thinking more in terms of building an entirely new system on a more standard motherboard, but I'm glad you worked it out to your best advantage. :thumbsup:
