CPU b0rked?

Hi folks, sorry for the lack of introduction, but I post this with some urgency,

My friend recently got a brand spanking new PC; specs as follows:

- Win XP64
- ASUS A8N-SLI Premium mobo
- AMD 64 X2 4400+ processor
- Corsairs PC3200 and Crucial PC4000 RAM from his previous computer.
- GeForce 7800 GTX
- All his old hard-drives plus a new WD 36Gb Raptor
- Zalman CNPS9500-LED heatsink
- Silverstone Temjin... 8 or 9? I forget off the top of my head, but it's a bloody well ventilated case.

Regardless, having got his PC running and finding that all of his temperatures were ludicrously low, he used ASUS's on-board AI Boost to see what sort of overclocks it would generate with a +10% increase. After a few minutes, the system froze and he attempted to reboot.

Without success.

Multiple times.

"OK, fair enough - it screwed the BIOS up - let's just reset it". One BIOS reset later and the PC boots. Excruciatingly slowly. Things don't get any better once it boots into Windows XP64 however, and a quick ctrl+alt+del later shows that the CPU is running flat-out at 100% load trying to run... well, anything; from explorer.exe to mundane.exe, it will try and kick out a maximum amount of processing power.

The computer being as it is (very new), we decided to just reformat the new Raptor and reinstall XP64. Now it won't even complete the installation for this and freezes consistently at the "39 minutes left" mark - the HDD formats perfectly. It's just the bit that actually involves going into the, uh, 'Windows-ey bit' for immediate lack of better term.

So, basically - is his processor shot? Should he try and see if he can get away with an RMA, or is this curable? We'd go and slot another processor in, but as neither of us have a spare 939 socket processor (or know anyone with a spare one/willing to lend us one), we can't confirm if the processor really _IS_ b0rked. Any suggestions?

Thanks

Try a "load bios defaults" operation inside the bios. It can't have been damaged by that.

check out the RAM that is currently installed. try running each stick individually. It may be a RAM configuration that is causing the problems you are having

Thanks for the quick responses guys - they're much appreciated in a situation like this. =)

mkk: Tried this to no avail - it still freezes over on the 39 minute mark. Moreover, we've ruled out that isn't a dodgy HDD issue - we've booted into safe mode on the old HDD Win XP32 install and the processor is still distributing tasks in a completely random and insane way.

CDsDontBurn: We'll give that a try, thanks. =) This said though, the RAM hadn't given us any trouble up until we tried to do this overclock; I'm not sure why it'd be a problem now. Moreover, would this account for the CPU random distribution of load that I've mentioned?

Thanks for the welcome!

Unfortunately, the RAM trick hasn't worked. We've tried each stick of RAM on its own and still no luck - it freezes at the 39 minute point each and every time; we've been giving it a very, very generous 15 minutes on each occasion and it happily cycles through the reasons of why Windows XP is better than anything ever made since... ever, but doesn't go beyond this point. I must confess I'm a total loss now. Any other ideas? =S

Windows could be borked, might be able to do a OS reinstall?

Neon: Ohhh believe you me, we've been trying that route many-a-time. We've formatted and tried reinstalling Windows about 4 times now, and it dies at the same point each time. =/

CDsDontBurn: Not tried a different Windows install disc - we'll see if we can acquire one at some point and try that out; it's not a possibility we've ruled out. It seems strange that the disc would utterly fail to reinstall Windows after just once, and especially after this.

Necrosis: First thing we checked (on the one occasion we did actually get back into XP64. =P) - everything was running at a perfectly acceptable level. The CPU especially is actually at 40C on load, so there's no way it can be an overheating issue.

don't just reformat the partition but select and delete the existing partition on the disk drive, and then recreate new one and start over clean. also, please read the resolution section in this article http://support.microsoft.com/default...b;en-us;828267 to troubleshoot the Windows installation hangups problem.

Ahoy guys. It's the guy who's computer it actually is here I'll try deleting and recreating a new partition next, but when we booted onto my hard drive with 32-bit XP on it was similarly slow, leading me to believe it was not a hard disk problem. Still - will keep you updated!

Update:

Tried deleting and recreating the partition, and it's still not making an progress beyond 39 minutes. Hard drive and CD drive are accessing, but just not getting anywhere it seems. Or at least it's going so slowly as to be stupid I'm starting to think that somehow the CPU did get borked, even if it's a freak occurence. I've changed every other component to no avail. Any other suggestions before I set fire to it all?

Progress! Kinda. Windows _DOES_ in fact install, but it's taking an EXTREMELY long time to do (i.e: it takes 30-45 minutes to go from the 39->37 minute process and doesn't get any better). I suspect once we install the OS, we will encounter the same problem however - does anyone know what could possibly be causing the whole thing to run so inordinantly slowly?

Your CPU is not getting enough power, I had this happen once. Make sure the power plugs that go into the motherboard are fully in. If that dosen't work, you might need a more powerful power suppply. How much are you running now?

Good point about the plugs - it seems unlikely that one of them would pop up (specifically after this AI Boost screwup), but it's something that's worth checking. The PSU itself _SHOULD_ be OK for this this setup - it's a Tagan 580W modular PSU, which is sort of designed for SLI'd 7800s, so if it can't handle the one...

Will look into the plugs though.

The quest continues - the plugs have been checked and they're all plugged in. Win XP 64 has been freshly installed, but the processor is still chomping away at 70-100% for whatever given (or not) tasks it has. As soon as taskmgr.exe opens, the cycles go STRAIGHT into this. Open IE at the same time? Then the cycles rapidly divide between the two. We've just tried manually setting shizzle in the BIOS but to no avail. I'd consider updating drivers, but I scarcely see the point, as we managed to boot into a similar installation of XP64 once before with fully updated drivers and this still happened. =/

Any ideas?

To isolate hardware from software, you could try booting the machine using the Ultimate Boot Disk (get it and make on another computer...) - available here:

The Ultimate Boot CD ( http://ubcd.sourceforge.net/ )

Note from your experience how long it takes the disc to boot, how fast the apps start, etc. You could run, say, Memtest86 to test the core components on the new machine - that app should fly...

There's lots of other neat stuff on that CD you can probably use to check your unit outside of Windows...

CDs: Nope - this is a brand new, fresh install of XP64 (with the ethernet cable removed to ensure no trojans are let loose) - combined with the fact it was doing the exact same thing before format and even on a different OS boot, it's not a software install problem.

Swim: This seems to be our New Hope, thank you very much for pointing us to this! We're currently putting the PC through a barrage of tests - the first one being the suggested Memtest86. I must confess to have not used this before; is it normal to get to Test #5 (Pass 37%) in ~13½ minutes with the specs I've listed, or is this far slower than it should be? =S

memtest should take a while, as it quite throughly tests the memory and the bus, but you should leave it to repeat for a few hours at least just to be sure you pick if there is problem with the ram

Ah.

So we ran the CPU Benchmark on the PC on that boot CD. It has the same processing potential as a Pentium 133Mhz. X(

Quiktest similarly reports a massive 65+ seconds or so as opposed to their reference Duron 1800 which got 2 seconds on the test, putting it at about the same level as a high-end 486. As you can understand, these results are a little below the expected par of an Athlon 64 X2 4400+.

Next question: What the HELL could possibly be throttling the CPU so badly, is it curable, and if not, which parts are boned, the motherboard or the CPU?

Thanks for all the help so far - we're getting closer and closer to finding out what's going on with this system!

Stick: BIOS was flashed to the latest version before we did the ASUS AI Boost of Death (tm), and it's still flashed to 1008 - the latest version. If that doesn't support dual cores (and Windows, CPU-Z etc is definitely identifying it as a dual core processor), I don't know what will.

Still at a wit's end for how to narrow down whether it's the mobo or the CPU that's screwing up without a replacement CPU. Curse you Socket 939 for being relatively-sort-of new!

well ... he can still use it as a big typewriting machine !

On a serious note, try to reflash the bios sometimes it can go wrong and while were at it just reset the bios to default setup prior to install .

Just tried reflashing the BIOS (yes, it really DID take 3 hours to get all the updates. =S) - no luck there either; was worth a try though.

Ok, last thing to check is : try the proc in another board and / or try another proc on the current board ... i know it's a little bit harder to do, but it should tell you wich one is bad .
