Random Pc restart HELP PLEASE!!!!

[Sticky Mick]

If it runs stable with a single RAM slot filled but crashes in dual channel, I'd have said one of the RAM sticks is duff.

Check the timings in the BIOS and compatibilty as well.

Also when you re-install Windows make sure you do the chipset/mobo drivers next, before anything else. Then install everything else and check for chipset driver updates on the web.

If you can use the same PSU in the P4 setup then there should be no probs with the same PSU in the AMD rig, as you're only running 1 card (AMD) as opposed to 2 (P4).

hey Sticky Mick yeah it dosent wanna boot with ram is in the dual channel slots but even if i swap ram sticks around it still doe it so it cant be 1 ram stick. im guessing its the mobo.

I know you have said that it isn't overheating but I'm going to blabber on about it anyway.

99% of the time I hear about PC's re-starting or shutting down at random it turns out to be a cooling problem.

I'd say don't just assume it isn't overheating, it costs nothing to make sure.

Take off the sides ( and top if possible ) and set a desk fan blowing into the case onto the Ram etc and run it like that.

Yes I'm stating the obvious, and yes it is as silly as asking someone whos car wont start if there is petrol in the tank, but it's allways worth checking

Good luck and hope you get it sorted.

side of case is allways off i have a coolermaster cm stacker 120mm frount fan(stock), 120mm cpu fan on a thermalright HR-01 HS, and a 120mm rear fan (stock). so it should have enough cooling and if it was overheating wouldnt it only do it when im stressing the cpu playing games or encoding or something not while its sitting there doing nothing on idle. atm cpu is at 32*c with cpu fan running at 400rpm (800rpm max) ASUS Qfan enabled.

if it was overheating wouldnt it only do it when im stressing the cpu playing games or encoding or something not while its sitting there doing nothing on idle.

Normally yes.

Not if you had a really poorly ventilated case though as the heat would slowly build up inside.

From what you say it sounds like ventilation shouldn't be a problem.

If I come up with any more daft ideas I'll be back

 

[drift-oz]

lol ok thanks for ideas anyway i just have a bad feelign its the mobo which i dont have time or money atm to get it checked out.

 

[Sticky Mick]

Could be a faulty RAM slot. Try and source some more RAM to try it.

I know how you feel by not having spares for troubleshooting. If I had some spare kit when my PC was playing the @rse it would have made diagnosing the problem a lot easier.

I've started scouring the bargain bins now so I can build some test rigs.

 

[drift-oz]

yeah spare ram would be nice but it cost me $600. even though i would like to run another 2gig soon along with everythign else i wanna do.

 

[drift-oz]

i have just moved my ram into the 2nd lot of ram slots but in dual channel 128bit mode and my pc has booted and is running ok atm hopefully i dont get any more random restarts. may have been like Sticky Mick said and having a faulty ram slot. thanks alot for your help ill let you know if i have any more porblems. im sure u will see me around as im planning a major watercooling makeover with case mods and stuff.

 

[drift-oz]

well i just got my first reset after running in dual channel for 5 mins. im now wondering is it the hdd maby or still mobo ram problem.

 

[Rastalovich]

Does the post say that it`s in 128bit ? Cos some mobos will only allow 128 if u use the first two slot - only some that I know of.

 

[drift-oz]

yeah it says 128bit in the post boot up. i have done somethign but i dunno what apart from move ram into 2nd lot of slots in dual channel mode and it seems to be fine atm even thought it was resetting alot last time with ram in same slots so i dunno whats going on. if i have any more peoplems i will be pulling it apart and mobo will be sent back to asus under worrenty.

I think the PSU is underpowered, and showing signs of wear. 560W's isn't enough in my book when running SLI/Crossfire, minimum 600W and 650W or better is my recommendation. New 8800GTX/S's have people recommending 700W+ PSU's for SLI.

Just because your PSU ran an Intel system fine, it may not be the same for an AMD rig. A good 600W PSU can be found for $100 bucks, a little more for a high quality brand.

Just to clarify, your system is good until you stress it, or does it just shut off randomly? Also, use CPU-Z to determine if your RAM sticks are the same (assuming you bought a matched pair), heard of some pairs that aren't the same. If not, may be affecting your pc (read: CRASH).

Memory and mobos are very strange bed-fellows at times.

U can have perfect memory on one mobo, move it to another and it fails, put it back and it works ?!?!

U can have memory fail all the time under memtest, give it to a m8 and it`ll work fine ?!?!

Use slots 1 & 2 and it fails, move slots around and it`ll work.

`Some` say slots 1 & 3 can be the best pairings. `Some` say slot 2 is the most reliable ?!?!

I think u just gotta accept that the above can happen from mobo to mobo and adapt to each seperate circumstance.

Glad to hear it`s working for u, I`d still memtest it in it`s apparant good situation.

 

[TJS]

Yeah, I never could understand how G. Skill has memory 'made for Intel', don't know why the same memory wouldn't work on an AMD rig if you set the voltage and timings right or at least in the ballpark. Mobos are a little less 'exact' to me, but they do provide the 'interconnect' of all the components that make up a pc... definitely more work if something fails.

im not running sli any more just a single card, single dvd rom, 2 hdds. and pc just shuts off randomly even on idle. no cooling probs no stressing just resets. but atm it seems fine ran 3d mark few times played games listen to music and dvds and avi's. so im stumped im gona send it back to asus ne ways. only thing i can think of to do. ram is matched otherwise it would have crashed on other system too. i will prob get a psu like this http://www.pccasegear.com/prod4301.htm once i get my W/C system too

ya i still dunon how to create a bootable dvd with the memtest iso so i havent tried it yet

Gotta agree, maybe your mobo has issues. But if you're going to spend $200 on a PSU, get a PC P&C 750W Silencer. 600W's for $200 is crazy, even if it is by Zalman, who isn't exactly known for their PSU's. (Great air cooling, got the 900's on my 7900GT's, just don't know about them as a PSU maker.)

Best of luck, hope the next mobo is a winner.

only PC P&C psu i can get is 470W for $165AU or the 1000w is almost $500 AU im guessing your talkign in USD $$$ too if u know your psu's can u tell me which is best to get outa these if u dont mind http://www.pccasegear.com/category15_1.htm i want something scilent, powerful, removable cables and no lights and around the $200 mark. Thanks

 

[Rastalovich]

Woah woah woah, u`r not in that much need for a psu.

I`ve got systems with a little-little-little less spec than u`r running on solid 400w psus, and they have more drives and addons than u`ve got.

(unless the one u have is in error ?!?!)
