latency / stuttering

[longhorn_54]

First of all English is not my first language...but I will try my best to explain my big problem.
So, about 3 months ago my pc randomly goes black screen i was playing gta iv, ok i thought something crashed and restarted my pc and everything was working fine, then after one or two weeks same happened but this time i was on youtube watching stuff and I suspected either gpu or psu.
After some time there was no black screen, i was playing csgo and pc started stuttering (audio and video) (i had win 8.1 back then) i exited all unnecessary programs, deleted junk files, defragmented my hdd but nothing.
Now I was 100% sure it was gpu (the culprit) but i wasn't doing anything. 2 days later i tried to turn on my pc but no screen, i tried taking out ram and putting it back and nothing. Then i tried my integrated gpu and it worked everything was fine. I installed win 10 because i was bored of 8.1 and i put my gpu in oven hahahha. Luckily it worked but i knew it wasn't going to work for long time. But the stutter was doing its job again I had like 250 fps const and it would drop to 80-90 and go back to normal every 2-3 min or so.
I tried to find a fix on google and saw latencymon and i've been trying to fix that problem last 3 weeks..
My gpu died again and i don't want to bake it again I started saving money for another gpu. But the problem now is pc stuttering even with the integrated gpu, i've tried a lot of things:
-high performance ******** (even i use high performance all the time)
-flashing new BIOS
-downloading drivers from the mobo site
-disabling hpet, speedstep, turbo boost, c states
-disabling drivers in device manager
-reinstalling windows like 20 times
-updating audio drivers, AHCI driver in devmgmt
-checking ram, trying even different psu
-updating intel r network drivers etc etc..

I'm running out of ideas, i really don't know what else to try, only thing i didn't try to swap is hdd but i don't think that is the problem i checked it with various programs and it is 100% health.
I don't have money to buy another pc because i got this one 6-7 months ago, i'm 17yo boy btw still going to school.

PC specs:
i5 2400
lenovo oem mobo
8gb ram ddr3 1333mhz
500gb seagate hdd
500w fsp 80+ bronze psu
and hd 5750 dead gpu haha

i know this is old hardware but for my needs it is good, budget variant. Thanks in advance

Sounds like both your PSU and GPU might actually be going or gone.

I would test with another PSU and of course you can always check the second hand market for a half decent GPU at a decent price.

FSP has been very known from use of cheap C(r)apXon capacitors. So best to assume those have reached their design goal of failure.
Connecting any new parts to that would be risk of throwing good money after bad money.

Also motherboard was certainly the cheapest tolerable to start with and likely has seen more than its share of wear and tear.
Bad PSUs also add to wear of other parts.

i tried a new psu, but the problem was the same, and as i said gpu is dead but its showing stuttering even on the integrated one
