Hey guys, I'm trying to help with my cousin's computer and I'm stumped...
it's a ~6/7 year old Asus gaming prebuilt PC. (i7-4770K)
About two weeks ago his computer would just refuse to boot, even Safe Mode would only work after many attempts. Tried repair installations, tried fresh installation, nothing.
Figured the SSD (a 120GB SanDisk) had run its course so he went out and got a new Crucial MX500 and installed windows on it and everything was great again... for a few days.
Then one night he had some Windows Updates to do, so he let it do the updates when he was getting off for the night.
It stalled and never recovered, was not able to boot back in.
Fresh windows install again.
Worked fine, installed drivers, played some Warzone (thankfully games were installed on a separate HDD that seems unaffected) and then got off for the night.
Next day, won't boot into Windows.
Ran Memtest just to be safe (he recently upgraded his RAM about a month ago) and it all passed.
Another format and fresh install, all good.
Next day, again, won't boot, even after having disable Windows Update.
Anyone have an idea of what the issue could be?
I previously was thinking maybe it was the MoBo (old VRMs degrading?), but he's not having stability issues (crashing/freezing) when Windows or Games (CS:GO, CoD:Warzone) are running... the issue only presents on a fresh boot up after being turned off overnight.
Could the PSU cause something like this?
I have asked him to check if the SSD and the HDD are on different power cables. My current theory is that his HDD is likely ona Molex poer connection but his SSD's are on a SATA Power connection and that rail is faulty. Might try a Molex-to-SATA (and hopefully not lose all his data) adapter temporarily to test.
Does this theory sound reasonable?
