'Recently built computer' Help needed

[Sammy]

Hi . I just built a computer for someone and once I had everything installed I turned it on. It'll anywhere from 3 seconds to a couple hours without randomly shutting off. I don't think it's the PSU. Could it possibly be bad screws? I have used 4 HDD screws by accident and not the correct number of correct screws. My second thought on the problem is that the I/O plate is touching the motherboard wrong ( There were metal pieces in the way I just peeled back. )

Thanks everyone,
Any Help appreciated.


Specs:
Intel E8400
ASUS P5QPL-VM Epu
4 GB Corsair 800 ram
Radeon 4870
Windows 7 ( It had been stopping before I even installed the OS tho)

is it your first computer?

did you remember to drill a hole through the cpu before installing??

 

[Emockler]

That would certainly stop the intermittent problem....

Hmmm... bad screws. Yup, that could be it. Especially if they are made of the wrong alloy. The harmonics created due the speed of the drive could be affecting it. Always remember, match the screw alloy to the rotational speed of the drive. 5200 rpm or less use a high chromium stainless steel. 7200 rpm to 10000 rpm use gallium arsenide/carborundum blend and something like 15000 rpm you must use "indestructible krell metal".

ROFL brilliant,

Sammy, all fun aside, always consult Google first!

Anyway, I've run into a similar issue before. It turned out that I didn't properly mount the CPU heatsink/fan to the motherboard. It was overheating and turning off. Mounting the stock LGA 775 heatsink/fans can be tricky- make sure its on there tight. One way I test is i (gently) pull up vertically on the heatsink to make sure that all the sides are locked in, you'll know if one side isn't pretty quickly. Since I dont have 10 posts, I can't post a link, but Youtube movie OFEOd7nQbuQ (or search for "lga 775" on youtube its the first result) has a tutorial on how to properly mount the CPU, heatsink, and fan.

It would be helpful if you could post a picture.

Are all the fans running??

It's probably something to do with the CPU bearings. If the bearings are not perfectly round than you run the risk of over rotating gyromagnetic reverse fields. You may also want to test the system board for shorts using a emf detector and the detectortron 2000 gauge. If you don't have one of those, then I suggest you call your local computer shop and get one.

lol! Don't forget to check the flux capacitor!

Did you ensure that the Jeffery’s Tubes are torqued significantly to preclude the introduction of nanites infesting the tubes and blocking the thermal balancing properties of the coolant circulating within the tubes? Although it is hard to have a “bad Screw” it happens once in awhile. When this occurs you should not have to pay. There is a little blue item that can turn your floppy drive into a Hard Drive and at that point the wrong screws can only get you into trouble if the little swimmers find a mate.

you guys are all idiots it can only be one of two things

1: the magnetic divvy coupler is not installed right

or

2: you have not pleased the pc by givving it a offering of a sacrificial cracker in the blu ray drive

 

[bagellad]

if the fans have not been turning on right, you need to wash them in your tears of frustration.

Static, I'll bet. One of my GF's cousins thinks he knows computers, and then sets boards and drives naked on the carpet. I'm gonna go with something like that here too.

Either that or the AA battery in the wallclock is sending magnetic interference.

Hello,

seeing how its you've never posted again i figure you fixed the problem. I own an ASUS P5QC and an Intel E8400 good choice by the way.

I would think that either your CPU is overheating like another poster has said. The Intel Heat sinks are a pain in the ass and even harder if you bent one of the connectors they must be very strait and you have to make sure that the connectors are in a retracted position before forcing them into the holes. If this is the case you will/may need to reapply thermal paste.

The other thing thing is that the ASUS P5Q series has picky taste when it comes to RAM you should research how to create a memtest disk at www.memtest.org. If your memory is a problem, try manually inputting the CAS latency and voltage into the bios, Examples. 4-4-4-10 2t @2.2vor 5-5-5-12 2T @ 1.8v if these numbers are not correct for your memory you will have intermittent failures, you can also try updating the BIOS from the ASUS website along with a guide in your mobo manual on how to do this. TIP the proper CAS settings are usually printed on a sticker or you can use newegg to find these numbers.

Lastly a poor performing PSU can wreak havoc on your mind, its a VERY important piece, and its usually the first thing ignored on everyone's first custom build. Regardless of the wattage a crap generic PSU will lead to a headache sooner or later. On my first (6 years ago) build i bought some Chinese 20 dollar PSU and I could not get my PC to boot. After two weeks of research I returned it for a Antec (which fried) then Enermax (great PSUs)!!!!

On this last build, I found my board and CPU freeze consistently when INTEL C-STATE is enabled. (off by default) If you can try and problem solve using different BIOS settings and peak at your temps/voltages from within your bios. The E8400 is a low wattage CPU and it runs VERY cool. If you peak at the temp in BIOS and its higher then 45C in a cool room there might be a Fan/heat sink issue. One last tip the P5Q series has a backup bios, if your make bad settings and cant POST unplug it from the wall wait 30 seconds plug it back in, or look in the manual for clear CMOS jumper. This jumper clears settings from BIOS so feel free to experiment.

Good luck and im sorry most no one wanted to even try to help.
