Solved Computer shuts off before windows loads.

April 3, 2012 at 15:27:11
Specs: Windows Vista, i7-900 series/6 GigsRAM
why does my computer keep shutting off during start-up?

i just got ;
eVGA X58 SLI3 - Motherboard - ATX - LGA1366 Socket
brand new. CPU is Intel® Core™ i7-900 processor series, I switched it in from my old motherboard. has a new DVD Drive. RAM, Video Card, and HDD is from the old. I put in the windows disc to start everything fresh, i don't care if everything is lost I just want it to work.
Sometimes it gets to the Manufacturer Screen, then it shuts down. Sometimes it gets to the Windows screen, then it shuts down. Sometimes it even restarts itself to boot up again. And sometimes it doesn't even make it to the Manufacturer Screen. But, it Beeps once every time it starts up.
And when I do put in the Windows Disc it doesn't read the disc because it keeps going to the setting of my HDD that is on there.
I tried putting in the Motherboard Disc in, I tried putting in the Windows Disc, no dice. The basterd will run/boot up/load from 5secs-30secs until it shuts down into Idle/stand by.

This happend with my old motherboard, thinking I should get a new one..until it wouldn't start up anymore. now it's happening with the new one.

What is the problem and solution please?

IT WORKS! took everything out one by one. double cleaned everything, re-paste the processor, one stick of RAM at a time when putting everything back together. No idea what caused the short, BUT I haven't plugged in the USBs in the front yet.
Again I would like to thank everyone for helping me out, sending me links on detailed information. Very much appreciated. Now I have another problem...the sound card, but that will be in a whole different thread. Again thank you very much.

You probably replaced the motherboard for nothing. I don't know why people start swapping parts out instead of performing logical troubleshooting.

First thing to do is to test your memory by booting to a memory test program. Download memtest86+ from the link below. No errors are acceptable. If you get errors then try running 1 stick at a time in the first slot. Snap it in and out 4 or 5 times to burnish the contacts.

Then run a hard drive fitness test for your brand and model drive. Get that from the drive makers site.

When installing Windows you should not have any unnecessary external hardware connected. Webcams, printers, scanners, flash or external drives, etc. Use a wired PS/2 keyboard if you can. USB keyboards may not allow you to access the BIOS screens.

Are you sure the motherboard, CPU, RAM are compatible?

Are you sure you applied the thermal paste or pad the right way?

Next time you boot tap the del key and enter the BIOS immediately. Check the system and CPU temperatures. You should also lookat the 3.3V, 5V & +12V values. They should all read +-5% of the default values. Post your results back here.

Also post the brand and EXACT model of your power supply.

Replaced it for the reasoning of "GEEK" squad. I did what I can with the resources I had at the time. they said it was the motherboard, Ram worked, new power supply worked.

where is the link for the memtest86+ ? and how am I suppose to test the memory with-out a working comp?

yeah I am using a USB Keyboard....I'll find a PS/2.

CPU and motherboard are compatible i'll do the MEMORY test you suggested.

as for the thermal paste. I applied it. should i re-apply it or run it without?

Power supply is Antec 650W max EA650 Earthwatts.

I have only one working comp shared with the household. So I won't be able to have any results till later this evening or tomorrow during the day. Appreciate your time and help.

"This happend with my old motherboard, thinking I should get a new one..until it wouldn't start up anymore. now it's happening with the new one."
maybe the problem isn't the boards?
sounds like overheating, check the temp in the bios.
"I put in the windows disc to start everything fresh, i don't care if everything is lost I just want it to work. "
isn't going to help if the problem is hardware.

You test the memory in the machine you are have problems with.

You boot to the test program. Sorry I forgot to post the link. It is now below.

http://www.memtest.org/

BTW, most helpers here will advise you to stay away from the geek squad.

You may or may not have applied thermal compound correctly. See the link below to learn how to apply. Look at the Arctic Silver 5 instructions for your processor type. Be sure to clean off all old paste with alcohol or lacquer thinner.

The hard drive fitness test is also run from the boot.

ok. i started pulling everything off one by one, i'm down to the power supply, motherboard, and processor being the only three connected. now it doesn't make the beep. it comes on for a second, reboots itself. As if it's trying to revive itself.

Sounds like the CPU cooler isn't clipped in well. Are you using the stock intel cooler? make sure that you rotate the legs of the cooler to the locking position before you mount it.

I'm just checking because I have seen people not clip these coolers in correctly.

So it's down to the nakedness of the motherboard, power supply, and cpu cooler. cpu cooler is locked in correctly, fan comes on, the power supply comes on.

If it was the Powersupply the motherboard wouldn't turn on right?
If it was the motherboard the cooling fan wouldn't work right?
If it's the processor it would just keep re-booting itself like it is, because the motherboard is trying to look for something to start it up?
Is that how everything works or is it a little different.? I appreciate all of your guys times and giving me the facts and places to make it work. I just can't figure out what doesn't work.
I could buy another processor, but has it come down to it being the processor just calling it quits?

I will answer your above questions in order.

1. Power supply can be faulty and still show signs of life. Boot into the BIOS (setup) screens and view the system and CPU temperatures and the 3.3V, 5V & +12V readings. All should be within +-5% of default values.

2. A motherboard can partially fail. A doubt that is your problem

3. If the processor was defective the computer would not start at all.

Follow the suggestions I gave in #1 in this response. Post back with results.

If your motherboard has integrated graphics then remove any add in graphics card and try using the integrated graphics.

With the computer unplugged remove all RAM sticks and insert only one into the first numbered slot. Snap it in and out 4 or 5 times then turn the computer and see what happens.

Do not have any external hardware connected other than keyboard and monitor. Remove all memory cards (not RAM) and flash drives.

You may want to contact eVGA and see if that board was manufactured with a defective sandy bridge chipset. There was a recall on some of the first batches from Intel. I have worked on some computers with the defect. Most of the time the SATA drives would disappear, or the systems would just crash.

It is worth a shot to do some research on this.

Vent, regarding the #9 response above it would help to know why you changed the motherboard out in the first place.

Were you having problems with your original hardware?

Also, you could try to take out the CPU and inspect the pins on the mainboard and inspect the contacts on the CPU.

Look for bent pins, dark marks on any of the contact pads or extra thermal paste.

I’m glad that you have solved the problem, and I admire your persistence with your computer and with the forum, as most people will not even follow up with their posts here.
