PC Keeps Shutting Down after Upgrading to a new Case

Hello everyone, today I switched over all of my hardware from my Gateway FX 6800-03h to a new case, the Antec 900 Gaming Case.

After all of the components were installed in my New case, I booted up my PC and since the first time I have had nothing but problems, all day, with the PC shutting down randomly and starting back up on it's own.

Sometimes it will happen at the Startup of Windows, and sometimes I will be able to make it to my desktop, but as soon as I launch a video game, the PC will shut down and start back up again.

I know it's not a problem with overheating as I'm looking at my temperatures as we speek and they are all pretty low due to the 4 Case fans on the Antec 900.

Using a 700W Power Supply I just bought last year...

System Specs are;

I also upgraded my ram from 9 Gigs to 15 Gigs using 3x 4G DDR3 Sticks and 3X 1G DDR3 Sticks.

The PC is fine as i'm posting this, GPU temp is 71C and core is 36C

However, I know 10 seconds after launching a video game on my PC, it's going to shut down and restart.

Any help would be greatly appreciated.

More about shutting upgrading case
  1. I would start by removing the 3 x 1 gig sticks. There is really no performance value to the additional 3 gigs. It is never a good idea to mix memory types. If the issue persists , check that all the MB standoffs are in place and properly tightened. Also check to see that nothing is under the MB that might be shorting it. Review ass the wired connections to the case switches and buttons. Make sure your usb headers are properly connected. Along this line do you show any errors in device manager? Since the problem just started you have identified two changes; the new case and the memory addition. This way you will eliminate one variable so you may evaluate the other.
  2. the problem is with the case as it is not grounded

    if the usbs are connected in one way or other to the case then due to constant static discharge from anything(ur cloths , hands , surrounding , carpet , etc) can cause. if the system power on outside the case without crashes then it is the problem of the case :pifff:

    what motherboard you are using , is it asus or ok it is of othercompany(gateway) but it must be saying after crash when you restart that the overclock has been failed and load default settings as he static charge makes the bios think that it is a overclock failure then it shuts down it self this happened to one guy

    hopes this helps :hello:
  3. My motherboard has 6 Slots for the Ram, In sequence the slots are colored from left to right, Blue / White / Blue / White / Blue / White

    If i remove the 3 sticks of 1Gig does it matter that I will have 3 empty slots, and does it matter which slots the remaining 4Gig sticks are in?
  4. The ram is to go into like colored slots. Usually use the slot closest to the cpu socket as the first color or number set. So if blue is closest to the cpu, use blue-blue-blue. No it does not matter to have an open memory slot set. In fact the system will work with a single slot filled. You would not derive the bandwidth benefit of triple channel of course. When testing ram sticks we often ask for them to be inserted in the first slot one at a time to verify they are good sticks or that the slot is working. It is never recommended to mix memory sticks that have different timings or voltage requirements. When using triple channel sets, it is important that they be matched to each other closely. Manufacturers do this when they sell them as a set instead of telling you to buy three of the same model. Besides the often referred to first 4 memory parameters there are several more. The entire set of them is recommended to be set to the same values for every stick in the system. You still may be able to add the 3x1's. I would recommend setting all the values and memory voltage in the bios manually, if you do. As I said you made two changes. The case and the memory. Removing one memory set is an easy way to eliminate it as the cause or variable in your issue(s).
  5. I don't think it's any of the internals if it was working before you swapped cases.

    Did you insert the motherboard standoffs properly? Not putting those in generally causes shorts and shutdowns.
  6. Yes all the standoffs are installed, there is 8 of them total and no extra ones touching the back of the motherboard. This was my first time ever doing any of this, the most I had done before was swap out an old power supply, so I am new to all of this, as for the ram, I removed the 3X 1Gig sticks and am now using just the 3X 4Gig sticks in the white Ram slots.

    Motherboard is a Gateway TBGM01.
  7. I looked at a pic. of your MB. It looks like the Blue are the first to fill. If the issues clear move the ram into the blue slots.
  8. It shouldn't matter if the RAM is in channel 1 or channel 2 - either one will be recognized as the primary channel if the RAM only populates that channel.

    Still thinking about what the problem could be...
  9. the problem is your case or the mobo
  10. Thanks for all the suggestions you guys, have since fixed the problem.

    Turns out the power supply was the culprit.

    Bought a new 750Watt and installed it and have not had one problem since.

    Was most likely just a coincidence that my old power supply decided to die after I swapped cases, that or it was the 4 fans in the new case that put it over the edge.
  11. Your system shouldn't have been stressing that PSU at all. Could be coincidence or there's something causing a short/etc in the PSU.

    I think you'd be able to RMA the old PSU since it's only been 1-2 years at most.
