View Full Version : Random Freezes

Oh great, PC has started doing random lock ups during games.

Not errors or BSOD, nothing in the log files...

Going to be a bitch to fix I can tell....

Nuke it from orbit, it's the only way to be sure.

More or less what I did. Booted from a disk to linux - stil geting freezes, so its not the OS

downloaded a memory tester and booted to that, runs test, machine freezes again.

reboot, drives spin up, cooling fans on but noone is home dosn't even get as far as the POST.

Going to try removing the memory sticks to see if that makes a difference but I'm diagnosing a dead CPU or MoBo. Not that it makes much difference which one it is as its an older Core 2 Duo - I'm not going to be buying a replacement for that socket just to test the theory. Looks like I'll be buying most of a new PC then....

Could have done without another big bill... Wonder if I've got enough spare bits to get something up and running, although it would probably be just an old Athlon XP chip :(

Pretty sure its not the PSU - MoBo wont even load the Bios and freezes were occuring independently of load or temperature. After a lot of messing around transfering bits into the Media center its definitely MoBo or CPU. And it doesn't really make a lot of difference which as the CPU is almost obsolete - so it would be a new one of each either way. ONly question is if theres enough bits lef to make it cheaper to build or buy of the shelf.

on the bright side the media center PC now has a new 500Gb harddrive and a 8800GTS GPU to replace its old GF7000 onboard. Might just about be fast enough to get some games on... Hmmm 32" game TV....

Well, if you'd just told me it wouldn't POST I'd say change the Mobo battery. It's a cheap thing to try, but I've got doubts about your earlier problems being caused by a failing battery.

Its not failing to POST - it won't even get that far!

Only signs of life are the drives and fans - so at least part of the PSU is working. I suppose theres an outside chance that one of the PSU rails has failed and left the others running but tahtt sounds less likley than a blown chip on the Mobo.

So whats the best CPU at the moment, i5 v AMD 6 core?

AMD? :p

you say that but look at the cost/power trade off.

Not going to be stretching to a high end i7 so its i5 at most if intel.

fastest i5 i can see is Intel Core i5 760 @ 2.80GHz - 4575 $205

compare to AMD Phenom II X6 1055T, 5174 $199

thats a 6 core processor too.

+ The AMD mobo will be cheaper and require only 2 RAM sticks for optimum speed (isnt the i5 a DDR3 3 stick solution?)

PC gamer Uk now has a similar AMD setup as its current recommended buy....

24-09-2010, 18:13:46
Yeah I was saying AMD is better :lol: my bad.

24-09-2010, 18:25:21
great minds and all that.
Now I just have to find the cash!

Using the living room PC is all very well but the screen is actually too big and the wirelss keyboard isn't very good. I have a very nice samsung screen in the office - I think its a 22" widescreen, or the next size up, much better than the HDTV. And doing work on the laptop is a pain when I'm used to having 2 A4 documents on the screen at full size at once.

Also i5's can be very easily overclocked. To good effect.

24-09-2010, 22:34:39
AMD is much slower per-core, typically.

Games don't really use more than two cores.

I'd lean towards i5s.

We just had a detailed thread on this on Poly. May want to check it out.


Also, check out the gaming benchmarks for the CPUs here: http://www.anandtech.com/bench/CPU/2

You can see the Core i5 760 is significantly faster than the Phenom II X6 1055T for gaming.

Batman: Arkham Asylum
Core i5: 187 fps
Phenom II X6: 180 fps

Dragon Age: Origins
Core i5: 142 fps
Phenom II X6: 102 fps

Dawn of War II
Core i5: 70.8 fps
Phenom II X6: 52.8 fps

World of Warcraft
Core i5: 89 fps
Phenom II X6: 63.8 fps

i5s are dual stick (dual channel) memory, just like AMD by the way.

It's the 900 series i7s that are triple channel.

hmm wont be buying anything for a bit so its a matter of looking to see whats available cheap at the time I think

Could be worse, I keeping wanting to read the thread title as 'random faeces'... :brwncard:
