Do you have a secondary graphics card to test with? If so, it should narrow down the culprit.
Hope this helps.
Hello. I went to turn on my PC today and it wouldn’t turn on. It makes five short beeps and doesn’t start. I’ve taken all of the parts out to clean them and put them back in again but there’s been no luck. On my manual, 5 beeps indicate a CPU problem but when I take the graphics card out and use a scart lead, the computer works perfectly, so it can't be a CPU problem. Could this be a motherboard or graphics card issue? The graphics card's fan still works when plugged in though. Any advice would be appreciated. Thanks.
Graphics card : MSI GEFORCE GTX 1050
Motherboard: Gigabyte B250M DS3H
