(1)How difficult it is for an individual computer to determine the cause of a computer failure
(2)personal experiences with Ji
(3)asdf3110 2020-03-17 Tuesday 0150 inquiry 3685 recommendation 24 recommendation
(4)1 Screen starts blinking for no reason
(5)2 When I connected it to the built-in graphics, the symptoms disappeared -> Oh, it’s a graphic card problem!
(6)3 Re-installed driver but symptoms still remain
(7)4 Graphics card decomposition cleaning and thermal re-application symptoms still present
(8)5 Graphics card AS. Why did you send me a fine one? It came back
(9)6 Monitor repairman call monitor no problem, sir
(10)7 Replaced graphics card but still symptoms – 1st mental breakdown here
(11)8 You can search on the Internet like crazy and do it with software including formatting
(12)I did everything, but the symptoms still remain
(13)9 Multi-Tep Replacement Symptoms Remain
(14)10 Monitor connection cable expensive replacement symptoms still remain
(15)11 RAM Eraser and Inspection RAM is fine
(16)12 Power Supply Max Elite 500W -> Antech 650W Bronze Replacement Symptoms Remain – Here 2nd Mental Breakdown
(17)13 All I have left is the main board -> I bought a new main board and bought a new CPU, so I bought a new RAM
(18)14 Surprisingly, the symptoms still remain
(19)15 No, the computer is completely new, but I thought about whether I should disinfect the case with ethanol or not, so I had a third mental breakdown
(20)16 I changed the monitor because I thought it was a problem, but the symptoms still remain <- 4th mental breakdown and giving up using graphics cards
(21)Since 17, only rolls and interchanges with built-in graphics
(22)After all this time, I happened to find out the cause
(23)What’s the cause
(24)To my surprise.
(25)It was because of the refrigeratorTada!!!
(26)The refrigerator is old, and every time the motor is turned off, the outlet voltage splashes, causing a momentary electrical problem in the graphic card, and the screen blinks
(27)In the case of built-in graphics, the power supply on the main board held up well, so it didn’t turn off
(28)presumption that
(29)When I connected the refrigerator to a different outlet, the symptoms disappeared
(30)It took me more than a year to figure out the cause after two months to get to 17 from 1 to 17
(31)That’s a record of a dog’s act
(32)Who would have known that the screen was going out because of the refrigerator
