[SOLVED] my PC was problematic. and it isn't after a few days

[using google in BSOD]

so, my second PC (the gt 730) was always rebooting itself every 30 seconds or longer.
after i ignored it for a few weeks, it runs well now. it isn't problematic anymore. 100% healthy.
what happened to this PC actually? maybe if this will happen again in the future, i can prevent it by doing something you tell

Can be PSU, or another issue. Need a more specific explanation. Do they act the same on BIOS ?
And what kind of restart ? After log in to windows ?

It could be faulty memory, run memtest86

it happens everywhere. but, it happened more often while it's at low power consumption.
like when i use a browser, in BIOS, in desktop. at the point, it happens more often while idle

is it a heavy program? or 100% harmless?

it's software tools to check if your RAM is working properly or not.
Since it's random restart, I would recommend to swap the PSU first. Then if the issue still persist, you can try diagnose another component.

I would have thought the same thing but I got caught out with this myself, told someone on here to replace PSU and the cause of the restarts was faulty ram.
