How to tell if the CPU is damaged?

[dbarcenas3358]

Hello all,

I recently decided to make an attempt at building my own computer. So far things have been going so-so at best. My first major problem was a wiring one where I shorted out the cpu cooler. I didn't notice this at first, so the cpu ran for a few minutes with no cooler. Looking at the BIOS I realized the CPU temperature reached 87C so I shut it down. I replaced the cooler and got windows 7 installed. Now, when I try to run a virus scan I get the BSOD citing a "uncorrectable hardware failure". I have run a memory test and that passes but I still need to run a hard drive test.

My question is if the CPU had been damaged due to high temperature, would windows still be loading and otherwise be running fine? The only time there is a problem is with the virus scan.

The maximum temp for that processor 72.6C so... I would be surprised if you didn't damage it.

Also, did you happen to read any of the manuals that came with the components you ordered?

Thanks, that's what I was afraid of. I've read them as I have been going along but I haven't read all of them cover to cover.

Try running more applications and see if the same problem occurs. A CPU failure usually would not let you boot your system.

I noticed that I spiked my CPU to 90C for a second running a very short and intensive benchmark (wprime). I thought this generation still had a thermal cut off other than the throttling but then again it might have just been a bad reading from the Asus software. Won't be trying to run a 4.9Ghz wprime benchmark again without serious cooling anyway

As the knowledgeable Ritwik7 says, try some other software. It might just have been errors caused to the antivirus install from the CPU when it was overheating, assuming you were in Windows at that point and the AV was running.

It also did it when I tried installing Starcraft 2 and during an update installation. It eventually let me install some of the windows updates but there is one I cant get installed (not sure if its a related problem, it doesn't blue screen it just fails to update).

The overheating was done pre-windows install. I was just happy the thing booted up at that point hahaha. So I took a look around the BIOS just to begin to familiarize myself when I decided to check the temp. The pc had been on for a total of 5 minutes its hard to say how long it was at that temp. Once I installed the new cooler and made sure the temp stayed under 30C, that's when I installed windows. Everything was going fine until that first virus scan.


I think I might try reformating and re-installing everything to see if that helps any.

Try running another virus scan and/or system intensive programs like some benchmarks (3Dmark, Prime 95 to name a few.) To see if your system is unstable.

Certainly worth taking a shot at re-installing to see if it helps, can't necessarily assume that the processor is cooked.

That 2600K is just amazing, you might be able to do 5 Ghz with more serious cooling

Meh, Corsair H50 and two 83 CFM fans and its still getting a bit hot with 8 threads maxed out at 4.7Ghz. Don't think I'll get much more without investing silly amounts into cooling. Might replace the default 200mm corsair fans in the case with something more powerful though.

Just kidding of course, I'd be doing cartwheels with the results you've achieved on your new build.

I've attached some of my minidumps , if someone would take a look I would really appreciate it. Thanks

the cpu should and probably did do thermal throttling and would have shut down when critical.
this is still true for the sandy bridge cpu's.

if it only happens with the virus scan then thats pretty much isolating your problem.
did you install all the drivers yet? chipset etc

as suggested, i also recommend a fresh install and try another virus scanner.
also, make sure you have all necessary updates installed

I don't have my debug thing set with the right symbols, oh well, but here's the bit you need.

Well it looks like I got it working so far. I made it through a virus scan yesterday with no problems.

When I got home from work, I decided to reseat the video card just in case that might be a problem and I also went into my BIOS to take a look at my memory settings. The timing and voltage were to spec but one of the other settings was set to "performance". I changed that to "standard" then loaded up windows. I then downloaded PCMark and 3dmark and ran both. I did have one hiccup with the 3dmark but ran it a second time and it went through with no problems. Everything seemed to be going ok so I ran another virus scan and it ran through with no problems. I also finished installing starcraft and played a game.

So far so good, I'm going to mess with that "performance" vs "standard" setting tonight to see if that was the cause. Eventually I would like to set it to "performance" if I am going to see some gains from it.

My only problem now is getting that last windows update to install.

 

[Mizzou]

That's cool, good to hear that your cpu still has a pulse.

Thanks and thanks to everyone who gave their input!
