Computer crash then no signal on monitor

Why is it that some people ask for specs? Knowing that does what exactly? As I have asked pretty much every Tech guy I’ve ever talked to. If your PC turns on fan and all, especially if the lights you refer to are on the front of the pc, that should mean your Pc is actually working and you just don’ see it. Sounds like your graphic card isn’t working or at least the problem is the video output and not the rest of the Pc. However your method of fixing the issue could be part of your current difficulty. Try resetting the pc. Turn it off and open it up make sure it’s clean of dust and check every connection (the HDD memory , disk drive, ect, even your SATA connections. Then pull the battery out for a minute, it should be the only one in there. This resets the BIOS. Now put the battery in, start it up. Use a regular monitor to check if you’re getting the signal from the pc. If that doesn’t work I’ll need more info from you.

I would try another power supply - have you a spare or can you borrow one to test?

After reading all the symptoms, I was almost certain it was your Graphics Processing Unit but after reading your specs and noticing that a GPU is missing I’m going to go with a Power Supply Unit failure. Usually a blown capacitor. It’s repairable but I wouldn’t advise it. Always invest on your PSU, it protects your computer which is more expensive than the PSU. Also, capacitors 99% of the time don’t blow up by themselves. You might want to install a UPS or straight up a Voltage Regulator to prevent future accidents.

It's a gigabyte issue I have had 3 gigabyte motherboards do this and frankly they are not worth going through the warranty process as I have done it and ended up poor repairs with bridged solder solder joints on controller chips. I switched to msi no further problems on all 3 of my computers running the same amd processors exc. Gigaby

"hello,

i also had this phenomenom randomly at really annoying times when i put two speakers to my equipment which draw a lot of power. Everything was on one socket, socket distributor. I searched on gutefrage.de and there was one guy also having it with much later equipment: rtx 3090 and brand new pc, so old components could not be it.

So I changed the socket distributor and since I did not have it. Seems like my previous one was not good enough to handle all this *****, i bought it at a discounter and it also seems really *****, if you ask me.

Also, I might add that the computer went a bit slowly before (latency when hitting windows key and latency on programs)and I reinstalled windows and stuff, never thought it could be a power problem.

Well, this changed the game for me. You might try this."

Im also haveing some sort problem when ever im gameing my pc will hard freeze then my display goes black saying no signal but pc turns at first i was thinking its the oc on the cpu but i left it stock for while and it happend again last night thing is sometimes it can take days or weeks for it to happen but when it does it normally good for few days/weeks till it happens iv let my mb setttings at stock and ram back to stock it only happend when i got new mb from ebay i had to reinstall windows so im thinking maybe its the mb or bad windows install.
