Signs of cpu failure

Hi

I would like to know what are some signs of cpu failure/defect. I recently purchased a new cpu and built a new computer. I have noticed that occasionally my mouse would lag for 1/4 a second and then continue to move again. I can't help but wonder if my cpu is defected.


thanks

Hi :) 

If if BOOTS its NOT the cpu...

Run a hard drive test in DOS...HIRENS CD etc, it sounds like a failing hard drive...

make sure the new mb bios is up to date a lot of mb have bios bug fixes for video cards..cpu code and usb devices. your mb may not have a bug patch for your mouse.

Hi :) 

In my shops we have had one day old drives failed...

how do i ensure the mb bios is up to date? I have the driver installed (with the motherboard dvd) already so I think I should be fine.


on the side note, what are the signs of motherboard failure??

Hi :) 

It is a hard drive that is BRAND NEW and still failed...

Most of the times I have encountered periodic lag, it got resolved by re-installing the OS... probably something going wrong somewhere along so many patches, driver updates, software (un)installs, etc. over the year or two between re-installs.

When HDDs start going bad, the whole system usually locks up until the OS stops retrying (often followed by a crash screen) or the operation is successful, which usually takes a few seconds. As it gets worse, the freezes become increasingly frequent and booting the OS takes forever if it even completes.

I have been relatively lucky with my HDD misfortunes since all my HDDs followed that progressive failure pattern which allowed me to recover just about everything every time before the HDD failed completely, usually while full-formatting it before RMA.

for the bios at boot hit the del key or f1 key most times on the first page will be the rev of the bios. the ngo to the mb vendor web page and see if it at the last posted number.

I've had a few HDD's go bad and it always presented (with one catastrophic exception) as an OS glitch. Things would freeze up and act weird. The problems would be intermittent, but grow over time. As mentioned above by others, I'd update everything and see if that helps.

so.....not cpu/motherboard?

Also "I would like to know, I just tried OCing my cpu and my computer frozen on me(i use easytune5). i was forced to reboot it and by the time it is in windows again the cpu clock jumps to 4.3 ghz with a 42 multiplier. i tried this a few times today and finally decided that it is too dangerous so i set everything back to default.

Given it was frozen, would i have accidentally damaged the cpu somehow?Could this cause lag in windows or games in the future?

While auto-overclocking often makes questionable to potentially dangerous choices, damage to the CPU is fairly unlikely.

Another thing to check (just in case) would be CPU temperature with HWInfo or other. Maybe your HSF isn't properly installed.

Yet another possibility is that your not-quite-stable OC may have corrupted some files in your OS. This happened to me at least twice. The first time, the OS would semi-periodically freeze while trying to reload corrupted processes and caused very long boot times while the second corrupted some boot files and caused Windows to crash during boot.

I am currently not experiencing any OS problems or anything. But I feel like I have been getting a bit of micro stutter while in BF3. I don't know if it has happened before I OC and im being paranoid or it is caused by improper OCing, so I would like to know if micro stutter in games are one of the signs that your cpu is damaged from OC?

Hi :) 

No your cpu is not damaged....

Cpu`s either work or don't work.... and if they don't work you computer will NOT even start...

I see,same deal with motherboard too? so micro stutter is either gpu/software?

Hi :) 

YES, to both... Gpu or software... OR CRASHING HARD DRIVE ...as I said earlier...that's the most likely culprit...

But isn't its performance/stability affected by improper use as well?

A CPU can certainly be damaged in ways that may not necessarily prevent it from booting if whatever damage occurred requires a particular sequence of events to trigger a failure and does not happen during boot. Not every structure within a CPU is absolutely critical and lead to obvious symptoms.

Ex.: busted 'hit' line in Tag-RAM may simply only affect addresses with a certain bit pattern when the address is put on a specific line of a specific set but work fine on any other cache line of any other set so the chance of running into the specific failure may be under 5% and even when triggered, all it might do is cause the CPU to evict another cache line and put the address there. The failure would remain almost imperceptible unless a particular patch of code causes tons of cache trashing involving that problematic line and address range which may make it behave worse than it should but still continue working otherwise normally.

You can have failures in an ALU that only manifest themselves when certain values are involved... think about the FP-bug on early Pentiums. Apart from divisions involving one of the few omitted lookup table entries in the FDIV circuitry, the CPUs were otherwise working fine. It took months for people to find out about it and several more months for Intel to admit this could be a problem.

Not every 'failure' causes CPUs to go up in flame or refuse booting. Many failures can cause subtle to nearly undetectable misbehavior that people may end up chalking up to random software bugs.

Hi :) 

Stop prevaricating...

Have you or have you not run the HIRENS hard drive test ???

no i haven't , I only see a hirens boot cd, hirens regenerator...etc on google. So Im unsure of which "hirens" i should be downloading.

tried using the hirens boot cd

but after selecting the hard drive test, autoscan doesn't show my hdd

i try using enter manually and just clicked something like the default ide port and it let me do a surface test, however the number of errors increase at the same rate the sectors are being scan so im pretty sure that's not my hdd
any idea?

Hi :) 

RMA the drive..its not unusual for even a 1 day old drive to fail...

working on it, but i bought it outside of us so it's gonna be a challenge.

But are there no way of getting the hdd show in hirens? it's just not showing so idt it is necessarily a hdd failure?
