Pc crashes randomly while playing games

[Adrian6432]

My PC has been re-booting itself randomly sometimes even seconds while playing games, at first i thought it was the PSU, but today i checked one of the games and for some reason it would lag horribly, like a non stop lag, even on the loading menu, i have no idea what it is and im completely puzzled by this, the computer doesn't usually crash on websites or other things but mainly games. I hope you can help me out in this horrible ordeal. My specs are:
Graphics card: GTX 770 4gb
PSU: CX750M
Motherboard: MSI 760gm-p21(fx)
Processor: AMD Fx4100 quad core 3.60 GHz
Ram: 8gb mushkin
i am useing windows 7 64bit

ive recently had an issue with my pc and similar problems like that, have there been any recent events leading up to the lag and booting issues

apart from me moving to a different room then nope, the crashes have been a thing for a couple of months but they would never lag a game.

anything that led up to your frequent game crashes then? My experience was a brief outage that caused my games to lag and crash when loading.

When i was moving rooms my pc was off and unplugged for a couple of hours, apart from that i was unable to play any games without them causing a restart on my computer.

Hmmm have you tried running your games with video coming from your mobo to rule out a bad gpu

how could i change that ? sorry im not very smart with these things haha

so if youre running an hdmi from your gpu, you just unplug it and plug it bin the back where all of your usb and sound stuff is, should be an hdmi port back there

i looked at the back of my pc and there was no entrance on my mobo for the HDMI, the only place i could put mt HDMI is the graphics card

ok so i don't know if this will help but i ran a furmark stress test, the first time i tested it my screen went black but everything else was on, i couldnt do anything so i restarted the pc, the second time i stress tested it it gave me a TDR message. when the test were on i could hear a weird noise coming from my GPU, it was like a electricity little tick noise, like a bzzt followed up with a really bad smell.

 

[ChellyChell]

that sounds serious, and if theres a smell it may be a heat issue not 100%

also just looked at your mobo and the only visual it supports without a gpu is a VGA

read up about it, apparently it could be cause of the psu giving out bad power, i bought a new psu, gonna check it out if it works then that's good, if it wont ill just give it back haha

 

[Adrian6432]

ill suspect the GPU if its not the PSU
