So yes, perhaps it is your power supply, perhaps it is your lack of thermal paste, perhaps it is both. If your PSU is providing too much current, the CPU would heat up more than before, and the lack of thermal paste would prevent the dissipation of this excess heat. Regardless, the best course of action is to consult a professional. You've killed 2 CPUs, and it's likely the case that someone would need to physically examine the components to find the problem. Consult a professional, then answer your own question with their diagnosis. | |
| Aug 1, 2020 at 17:44 | comment | added | barlop | @RajatKhanduri still is possible that the PSU is bad, and it's possible that the PSU destroyed the MBRD. And it's possible that the PSU is bad but the motherboard is fine. And it's possible the CPU has an issue(don't make assumptions about things being fine and not thinking they need testing). A repair shop is PERFECT for diagnosing this 'cos they have parts and can do these tests really fast maybe for a small fee. Even while you wait. Swapping PSU, swapping CPU. Thus indicating what part is faulty. | |
| Aug 1, 2020 at 15:25 | comment | added | Rajat Khanduri | @VividKraig but I have been using it w/o thermal paste since 1-2 year, even used to play 15 GB games, but the CPU didn't get killed before :( | |
| Aug 1, 2020 at 15:19 | comment | added | Rajat Khanduri | @barlop The CPU isn't even a bit warm. I have waited half an hour to 10 hours to days but it won't work. And yeah, it doesn't "run for 25 mins and then turn off" rather "it just worked for 25 mins once and then turned off and never booted again, no matter how many hours I've waited" :( and the green black test is successful for 1 hour, the PSU fans are still running and it's been 1 hour :( | |
| Aug 1, 2020 at 15:15 | comment | added | Rajat Khanduri | @barlop yeah, I'm just booting with ATX 24 pin, CPU 4 pin connector, CPU, CPU fan and sometimes the 2 GB ram stick. For PSU, I will try another PSU in some days (will probably go at a repair shop). Thank you :) | |
| Aug 1, 2020 at 15:13 | comment | added | Rajat Khanduri | @John I have been using this PC without thermal paste since 1-2 year. Only after this incident, PC won't boot. Also, thermal paste ensures better heat transfer, but if the CPU isn't even processing and starting, what's the use of paste? I might be wrong but PC's do boot w/o paste. In my case, it is not even booting | |

| Aug 1, 2020 at 13:37 | comment | added | Kraigolas | If you're not using thermal paste, it's possible you killed the CPUs with overheating, not all CPUs will thermal throttle to protect themselves. Try the CPUs on a different motherboard if possible. | |
| Aug 1, 2020 at 13:10 | comment | added | barlop | If it had only turned on for a few seconds then off, then (reminds me of some years back when another cable needed to plug in there).. But for your case that's not it.. Your case it runs for 25min then turns off, and then perhaps doesn't turn on... If you wait half an hour does it turn on? If so, it could be an overheading issue. If it doesn't boot at all then maybe a bad PSU killed the MBRD. Really you should change PSU. Also try a green-black test for eg 1hr.see if it stays on for 1hr.(albeit with no load) | |
| Aug 1, 2020 at 13:02 | comment | added | barlop | To make things simpler, you can unplug your hard drive, and optical drive. . A computer can start and stay on without them. And of course don't need an optical drive connected. Also your title says you changed MBRD and Processor, but doesn't mention if you change the PSU. The "green-black wire shorting" method is perhaps not a sufficient test for PSU, if it passes it just means the PSU isn't completely dead but is possible PSU may be funny. | |

| Aug 1, 2020 at 12:40 | comment | added | anon | I am surprised it would run for 30 minutes without proper thermal paste. Reinstall the CPU with proper thermal paste and test again. | |
