After 5 days of installation of a Corsair GS700 power supply and proper performance, my ASIUS/AMD PC just won't turn on any more. A brief flash of leds and then off again.
You do not say if the previous power supply failed or not. If the old PSU burned out, it may have damaged the Power Management System or blown some capacitors on the motherboard.
You do not say if this is a custom-built or factory-built PC.
The issues to check are if anything on or around the motherboard was disturbed during installation.
Start by removing the new PSU and removing the 2nd side panel and shaking the pc side to side to see if any loose screws are lurking under the motherboard or rolling free in the case, potentially shorting the solder points under the motherboard.
Are the motherboard screwholes properly aligned with, seated on and screwed to all the correct mounting points on the motherboard? A misaligned mounting point might short the solder points on the underside of the motherboard.
Are all the RAM modules properly seated? Is the graphics card seated properly? Is the CPU fan connected?
Is the CPU properly seated? Remove the heatsink, clean the CPU and heatsink surfaces, reapply heatsink paste and carefully reseat the Heatsink.
Was the case full of dust, dirt and grime when you changed the PSU? Is there a caked layer of dust between the Heatsink and the heatsink fan?
Are all the cooling fans free of dust and grime and connected properly and are they cooling adequately?
Ideally in a gaming system, a fan should draw cool air low into the front of the case, another fan should draw dispersive cool air into the side of the case, a fan or fans should vent hot air out of the rear of the case. The CPU heatsink fan and power supply fans automatically vent hot air from the CPU and the PSU motor.
Any fans missing should be added to improve and optimize cooling efficiency.
Is there any caked dust and grime between the front panel and the metal chassis of the PC, disrupting airflow sucked in by the front cooling fan?
Are all the cables tidily cable-tied to minimise dust traps, hot air pockets (especially near devices that generate heat like the hard drive(s), optical drive(s) and graphics card and to minimize the restriction of air circulation.
Is the graphics card fan free of dust?
Place the PC on its side. Disconnect the PSU and connect it again starting only with the motherboard connection make sure all 24 pins are oriented correctly. If it is a 2 part connector make sure the 2 parts clip together correctly using the printed guide arrows on the side of the connector. Then connect the CPU power connector, the the HDD power connectors, then the graphics card power connector (if it has one).
Remove the small nickel-sized CMOS battery for 2 minutes then reinstall it, to clear the BIOS from the previous crashes.
Recoonect the power cord.
Then test the PC, leaving it open and flat down so you can easily see all parts of the pc.
If all is well, shut down, disconnect the mains power cord and connect the Optical Drive power connector and all the fans and the test the PC again to see if all the fans work and rotate at the correct speed.
If all is well, shut down, unplug, close the pc, reconnect and power up to test again.
Do not place the PC directly on the floor on a carpet with a thick pile as this can obstruct the inflow of cooling air from the floor-level front air intake. Place the pc on some sorm on platform like a plank of wood or cardbord to leave a cler gap for air to flow in
Hope this helps.
