CPU is being underclocked? How can I fix this?

[salmonboyak]

So I’ve had this PC for about one year now, I've had a friend help me build most of it, so I don't know much about this PC, I no longer have contact with him as well unfortunately. Ever since I first built it, my CPU has been running at 0.78GHz. I am not a computer wizard, so I don't know much about this kind of stuff, though I've tried many ways to fix this problem. Recently I’ve clean installed windows once a few months ago, which didn't help. It’s not the temperatures and there’s no dust in it. I already set the Power Plan in Windows to High Performance, did the minimum and maximum thing that I should be doing, still no luck. It never goes to 100% CPU usage, and it usually is around 20% when playing a game such as Overwatch or Siege. CPU speed never goes up at all. No other parts of my PC are a problem either, they work fine.

Also when I went into the BIOS to check some things about the CPU, I got some info:

Frequency 800MHz
Temperature 25C
BLCK 100MHz
Core Voltage 0.720V
Ratio 8x

I will appreciate any help and support I can get.

My Specs: ASUS Prime H270-Plus, 8gb RAM, i5 7500 @ 3.40GHz PNY GTX 1050, 450W PSU (Though I'm not 100% sure about the PSU)

Userbenchmark: http://www.userbenchmark.com/UserRun/9665814

(The userbenchmark says there’s lots of background usage, but I’ve closed every process that I can)

Download/install/run HWMonitor, then even a Defender malware scan should show clock speeds jumping from 800 MHz to between 1200-3400 MHz or so for the duration of the scan....

Is the cpu correctly identified as an i5-7500 in the BIOS? And in task manager/performance/cpu?

Yes it is correctly identified as an i5-7500 in the BIOS and in task manager.

Where are you seeing 0.78GHz ? Task manager or BIOS or.... ?
Personally, Id reset the BIOS to factory defaults - but this can lead to small issues as well, so best to have someone knowledgable on standyby.

I am seeing 0.78GHz in task manager. I also have already tried setting BIOS to factory defaults.

are you seeing a peak of .78 GHz during an actual load, such as during a Defender scan, etc..? (Make sure BIOS cpu options also set to either balanced or performance...)

Think you're thinking along my lines, no load - no CPU use 😉 My G3258 would show under 1GHz until I loaded it then itd work its way up to 3.2 in task manager.

Try running something like Performance Test and see what it returns - if it matches your userbenchmark, something is def wrong. Check for BIOS updates etc.
