Hi!
My Dad has an HP Pavillion p6735a (https://support.hp.com/nz-en/document/c02681086).
It was getting old and slow so I replaced the HDD with an SSD, installed an extra 4GB of RAM (taking it to 8GB), and updated to Windows 10. It made a huge difference and was running really well.
However, the PSU started to make weird noises (as if the bearings were all worn out or something) and it was annoying him while he worked (and was potentially threatening to fail I guess), so I bought a Cooler Master 450W PSU (https://www.pbtech.co.nz/product/PSUCLM1450/Cooler-Master-MWE-450W-230V-80Plus-White-PSU-MEPS), which I thought had more than enough powered based on the old PSU and a 'NewEgg' calculation tool.
I installed the new PSU and it ran well for a few days, before the computer wouldn't boot up again after being shut down. We but the old PSU in and that worked, so I figured it must be a faulty PSU (or I had somehow killed it) and we got a replacement from PBTech (thanks!).
I've installed the replacement and that had been running fine for a few months, until I got a message from my Dad yesterday saying he had put a CD in the drive and the computer had then shut down (may or may not be correlated) and wouldn't restart. We troubleshooted a bit (tried unplugging the power and SATA cables to the CD drive and booting) but nothing worked, so we switched back to the old noisey PSU and it worked...
Are we killing PSUs somehow?! And if so, how?!
I have done some reading and people say a dodgy wall socket could be the culprit, and surge protectors should be used, but we've never had any problem with other equipment using these wall sockets and we use surge protectors.
Could it be another faulty PSU?? (surely the chances are low...). Is there a way to test if the PSU is faulty??
Any guidance or potential explanations would be greatly appreciated, thanks!!
