Question CPU issues after power outage ?

A few days ago my power went out randomly in the middle of the day, after I turned my system back on after the outage was over, I noticed poor performance, poor loading times, and stuttering during my downloads.

Being the idiot I am I decided to factory reset my pc and lose all my files. After that I ran some tests on my pc and found that mostly what was acting up in my pc came from the cpu, it fluctuates and the temps are higher than they are supposed to be at most times, as my fans on my pc are visibly loud pretty much all the time.

During idle cpu does fine but when I bring other applications into the mix it fluctuates abnormally, no specific windows task is causing anything to fluctuate, really anything does it.
(also my network usage is screw up as it just spikes and declines over and over again even while idle)

A power surge, when the power was restored, could have damaged one or more hardware components . . . Is your computer plugged into a UPS?

Do you have a recent system backup from before the system outage? If so, try restoring it. If the problems persist after the backup restore, odds are that you might be looking at a hardware issue.

Have a great day.

I completly restarted my computer, I reinstalled all drivers and all of that.
If this is a hardware issue what could I be looking at?

If it was my computer, I would look first at running HDD/SSD diagnostics and a CHKDSK scan to ensure that the health of the HDD/SSD.

I had a client who got hit with a surge. It took out her PSU and network hardware. Thankfully, her HDD was spared, so I was able to recover her data.

You haven't told us the make and model of your computer. I have Dells, and they offer a pre-boot assessment suite of utilities to check all hardware components. Other manufacturers may have similar suites. If so, I would run that as well, if available.

As @rgd1101 has suggested, it really would help to know the specs of your computer, and how high the CPU temperatures are. Otherwise, we are throwing darts here because we can't research your problem, if we need to, because we have no idea of your computer specs . . .

Please help us, help you.

Have a great day.

I received your PM, but like most people, I am not on the Forum 24/7. I visit a lot of Forums, live by myself with a dog, and have a "real life." I appreciate that you are anxious about your computer, but please be patient. Everyone here is a volunteer, and to be commended for sharing their time and expertise to help others. In my case, I am a relative newbie on these Forums. My primary, and dubious expertise, is mostly on the software and malware side of the house.

From what I see, your computer is not an OEM build. That means you won't have a suite of pre-boot hardware assessment tools that I mentioned as an option.

Unfortunately, the computer specs that you have shared do not indicate the number or size of the disk drives connected to your computer. 😕

CHKDSK does not check the health of drives. It looks only for Windows file system corruption. My recommendation is to check the health of your drive(s) first, using good diagnostic software. Personally, I use HD Sentinel Pro to monitor my three internal drives, and any external drives that are connected.

I don't know the age of your computer. It might just be a dying CMOS battery, although nothing you have described fits that bill, but strange things do happen when the BIOS has inconsistent memory, due to a failing CR 2032 battery.

I am throwing darts here because I don't know if you have "Fast Startup" and "Hibernate" enabled. Both of them would not "like" a power outage. I have both disabled on my computers because they can cause issues.

Before speculating further, please identify your drives, and run diagnostics on it/them with the manufacturer's testing software or HD Sentinel or another reputable drive testing program.

Also, although it is a very simple solution to many computer issues, shut down computer entirely. Unplug the computer from its power source. Press, and hold the "Power On/Off" button for 30 seconds. Release the power button. Reconnect the computer to a wall socket directly, and report your findings.

Hopefully, one of the gurus here will have more cogent advice for you, and will chime in.

Good luck, and have a great day.

Regards,
Phil

Oddly enough, I had to use the "trick" I told you about in my previous post.

Today, my monitor went blank while completing a long backup image (178 GB) to an external hard drive. The monitor suddenly reported it was not receiving a signal from the computer without any warning or signs.

First, I reseated all of the monitor and computer display cables. Lots of beeping ensued, but no joy.

I waited for the copy to be completed, based on a time estimate, and then unplugged everything. I then did what I suggested you try.

Then, I plugged everything back in, and my video monitor started working just fine. Don't ask me why? I am not a hardware guy, but that "trick" has solved many a mysterious issue for me and others.

I hope that you solve your issue. Have a great weekend.

Phil
