My computer's CPU, GPU and Memory's usage is all low but my computer is very slow

[trechh]

My computer had a problem that if someone was to stomp on the floor around the computer it would turn off, so my friend decided he would try fix it. He took apart the computer on my bed and cleaned everything and put them back in. We booted up the pc to it not working the first few times, but now it runs but the fps is unbearable ( 0-20 FPS on all games) compared to the high fps I used to play on before he took the computer apart. There is also delay on the desktop and in google chrome and a 2 minute extra boot up time. My friend says its the power supply but i don't know if he actually has a clue, he did mess it up in the first place.

My Cpu, Gpu and Memory all have a low usage that barely goes above 20%, my hard drive and ssd are at 50% capacity.

If anyone has an idea of what is bottlenecking my pc that would be greatly appreciated.

Specs:
Intel Core i-7 2600k @ 3.40GHz 3.70GHz
NVIDIA GTX 770
16GB of RAM
GIGABYTE - Z68A-D3H-B3 motherboard
1 Tb Hard-drive
250 Gb SSD

Could your download and run HWMonitor, and upload a screen capture or 2 of it showing voltages, temps and clocks while idle and then while gaming ?

__PHYSICAL CHECKS :
- I would first check that all cables and connectors are snug : starting from PSU external wall power cable and ending by fans and drives connectors
- check and / or reseat memory sticks, ideally CPU/ motherboard CPU socket pins visual check
__ BIOS SETTINGS: clocks and voltages
__THERMAL THROTTLING: Monitor CPU, system and graphic Temps
__ POWER SCHEME THROTTLING: verify that your windows system is running your computer at appropriate power scheme ( high power ideally when gaming)
__STRESS TESTS : components at stock clocks stress tested for stability (detecting configuration or physical defects) MEM test for memory, CPU, VGA stress tests.
__Best way to physically troubleshoot a rig is to reduce it to it's bare minimal components having motherboard out of the case with CPU, Ram, boot drive and PSU, also swapping spare components would help hasten the process by quickly ruling out some of the components.

The top two are gaming and the bottom two are idle

You mentioned the PSU in your opening post but it's nowhere to be seen in your specs list (make & model required) - - - the PSU is just as important as all the other components you've listed - -

Thanks for the upload - which is definitely missing Motherboard voltages (3v, 12v, etc) from the screen captures- as mentioned above by Phillip, if you could add couple of those screen shots on those "Mobo Voltages" while idle and then while gaming could be very helpful.

While gaming your CPU at 96 C seems to be thermo-throttled at 570 Mhz and around 90% usage (sweet spot temperature wise while under load between 50 and 70 degrees, above 80 degrees is considered quiet hot temp for this CPU, Your discreet graphic is running coll at 50% usage, 35 degrees probably bottle necked by your CPU, Your integrated Intel HD graphics running really hot (part of CPU) .

What is strange is that your CPU while not gaming is still running very hot at 93 degrees with 30% load at a throttled 1500 Mhz ! while your discreet graphic is running at better clocks than when gaming but at lower utilization.
CPU AND SYSTEM FANS seem to be running at full speed in either modes with not that much of cooling effect.


Your CPU probably needs a better cooling solution to keep it's temp below 70 under load, you might also consider visually checking your CPU and it's motherboard socket for defects or un-even assembly, and also verify CPU-Mobo power delivery.
What CPU cooler are you using?.
