Question PC Randomly reboots

[Taylor9484]

Hi there. Bit of a PC novice so bare with me. My PC will randomly reboot itself when playing or starting up games. Even done it once on google chrome. I’ve just got a new CPU heatsink and the temperatures are all normal, the voltages seem normal and I done a test to see if any of the hardware was failing and it said no problems detected.

Here is the specs

can you please tell me what your psu is.I cant find it in that chaos.Also rebooting happens when the cpu overheats(but you said your temps are normal) or it happens cuz the psu is too weak.

Do you know what make and model of your power supply? i had an issue similar to this and that was what turned out to be the problem for me

The PSU is pretty rubbish. A corsair VS450w. I’ve just done the OCCT stress test. My CPU crashed after about 4 and a half minutes. The GPU crashes the system immediately. I don’t get it I was playing games fine a few weeks ago.

Stress 😭

I realise my parts are pretty old I just bought this off a mate and for the first few weeks eve thing was running fine.

Seems 80+ rated and like it would be enough wattage for a 2 gb gpu and an old processor, could it be the gpu that is going bad? try removing it and just running some cpu stress tests and see what happens

I bought a faulty power supply from a cheap manufacturer, my mistake but i did notice audible popping and crackling sounds under load that would then shut the system off in much the same way, so maybe have a listen and see if you hear anything unusual when you stress the system

[SOLVED] - PC crashes and restarts randomly when playing games

I build a pc for the first time and I am having problems with it, it keeps crashing and restarting when i play games. Sometimes I can play a game for 3 hours without crashing and sometimes it crashes after 10 seconds into the game. I don't know what to do, I stress tested my gpu and cpu and ran...

Think this is it for you

 

[Taylor9484]

This could be a silly question but how can I run the test with no GPU in? I can’t see 😂

 

[Mickieg1994]

If the gpu is removed the output will default to the onboard graphics for the motherboard, so you will need to plug your monitor cable into the rear IO on the motherboard, If it is a fairly modern motherboard it should have all the basic connections needed

You can also change the settings in the BIOS if you don't want to physically remove the card but it's more complicated than it's worth

In my case i took my 4gb rx 570 out and put my old 2gb amd 6670 back in and the problem stopped occuring, in my case the power supply was not providing a stable enough current and the pc shuts down to prevent damage from over/undervolting, it's a safety measure, if your psu is old enough it could be failing when it has to draw more power under load

 

[Taylor9484]

I’m afraid it’s not a modern motherboard and there is no where on it to plug the monitor in. I done the CPU again at it only lasted 58 seconds this time. GPU crashing straight away. Time for a new PC? 😂

 

[Mickieg1994]

Quite possibly afraid to say, if you have the time and the means i would say two last ditch efforts might be to try a friends power supply in the machine, and to try reseating everything except the cpu and cooler, take it apart and put it back together, on rare occasions it can resolve the issue, as a faulty power connector not pushed in all the way or something not quite making perfect contact with the socket can cause issues but they would of presented themselves much earlier, making me think it is a dying part/s

 

[Taylor9484]

Just tried disabling the HPET timer (no idea) and I ran the CPU at 100% for 5 minutes on a stress test and it didn’t crash. Maybe there is hope!

Might also see if I can get a hold of a friends GPU and see if I get any more luck.

Just annoying because a few weeks ago it was fine and I was playing games all day

 

[Mickieg1994]

Huh, that is really interesting, is the gpu still crashing right away when tested?

 

[Taylor9484]

I’ve tried it a few times and the furthest I got was 1 second...

Interesting the CPU held out there and probably could’ve kept going. Not sure what my next steps are. Seen suggested since my graphics card is like 7 years old and I have installed the latest drivers they could actually be too new for the card if you know what I mean.

Also someone else has told me my PSU is too weak and my card needs at least 500w.

I just wanna play and stream without problems 😭

 

[Taylor9484]

So...do we think the Graphics Card is totally dead then? Or is there a way to save it?
