First off, system specs, all around 4 years old:
Asus P5Q-E MoBo
Intel Core 2 Duo E8500 @stock (3.16GHz)
4GB G.Skill 1000MHz DDR2 @ 800MHz (was at 1000MHz before issues below)
HIS ATI Radeon HD4850 1GB
Corsair TX650W PSU
3x HDD
1x ODD
Asus Xonar DX
So last night this PC gave me a scare, as it was about to sleep, heard all fans kick in to max speed, then reboot.
Only it rebooted with default BIOS settings, so didn't detect boot drive. Changed BIOS back to normal, and it got through post, from which I saw that all hard drives (SMART) reported OK.
Took a long time, but did boot back into windows, slowly. Checked GPU/CPU temps, all seemed ok, system seemed to be running normal.
So I tried to reboot, see if boot time went back to normal, and it hung on reboot. The GFX card fan seemed to spin up to max, so opened the case and had a look,and the GFX card has a LED on, labelled D1602, which from some searching tells me it shows a EXT12V Fault. So thinking it could be the PSU on its way out?
BIOS shows +3,+5, and +12V lines all a bit under their targets, but not massively, I remember +12V was 11.92, think +5V was around 4.95.
Would appreciate a second opinion before I look at buying a new PSU, but am thinking it could be any of the PSU/MoBo/GFX.
