Random reboots

albert · April 19, 2003, 07:20:33 PM

Hi Folks,

Well fate may be playing its part in my forthcoming pc build. My current pc has started to randomly reboot itself, 4 times now normally after it has been powered up for extended periods of time.

I went into the BIOS and checked the system status and the CPU temperature was 59 degrees. A bit much I think. Also the psu system fan was show 0 revolutions per minute although after a quick check it was in fact working fine. I suspect a mixture of bad ventilation, messy innards (cables mainly and tight space), and poor transmission of heat from the cpu to the heat sink is causing the thing to heat up a little too much.

I have moved the pc to a more airy place in the room and removed the side panel to let things cool a bit and found it to run at 51 degrees idling.

I have a minor problem if I wish to upgrade this system, the mobo only supports up to the current Athlon that I have so it looks like I'll be getting:

XP1700+ o/c ed
ABIT NF7-S v2.0
Enermax EG465AX psu
Zalman Flower CNPS6000-CU
GAT001 Case
OCZ Twin 2 x 256MB PC3500 Dual Channel DDR RAM

I can get the new rig setup before I have to move the following older, more moveable parts out the old:

GEF 4200 Ti
SB Audigy
2 x 40GB HDDs
Floppy
CD and CDR

Boy oh boy my credit card is about to take a pounding. But it should be worth it. I woudl love to be a able to slip a 120GB HDD in there and do a clean install on it but my budget is a bit stretched as it is.

Mine had that probs during rebuild, I simply cut a hole in the side panel and fitted an extra fan, it worked wonders!!!

Cheers mate, nice idea, I suppose it's logical. Now where the hell is my hacksaw? :lol:

BTW removing a panel frequently makes heat problems worse! PC cases are designed to allow drawn in air to flow over components and out the back. Removing a panel changes the airflow patterns and consequently the cooling of components.

This advice will self destruct in 5 minutes.

Yeah I agree, but when you see the mess in my case there's no real channel for air to flow through in the first place with all the darn cables in any old way. Also it was stuck between a desk and a wall, not stuck fast, there was space all around but I would imagine that the placement wasn't too good too.

Albert, I have had a look at the above list and the case in particular (I must have missed that in the previous thread or else it is a new addition to your list). Have a look at this review. The Enermax is an L type PSU and so you may have problems (cos GlobalWin put the screw holes in the wrong place :oops: ). There also seems to be a minor issue with the length of the fan connectors? It is suggested that these problems will have been fixed with the GAT002. I couldn't find reference to 'when' they will have fixed this or issued the new model other than an oblique reference to 'August' - but I don't know if that was August last year or this

So I'd suggest you contact the below chap who is their UK distributor, to check about the PSU issue first.

With the exception of the case and the gfx card I am getting the exact same system, so we should be able to compare notes about overclocking it

BTW, the OCZ memory sticks weigh a ton! Copper heatsinks on both sides - but they look nice and shold go real fast. I'm hoping to have a system in place and running within the next 3 weeks, so fingers crossed :?

Invest in a chieftec case. I did and cpu temp went from 61 deg C to 43 deg C (case from 55 to 29 deg C). Except from the temp reduction you get a very nice case that is easy to work in.

I have a Cheiftech case and put a Zalman flower in...the problem im having is that the 2 fans at the rear are very close to the Zalman fan and i think causing problems either pulling air away from the Zalman fan or battering air onto it :? this may be the reason it is also quite noisy now :cry:
More investigation needed :puppydogeyes:
