When handling motherboards and any sensitive ICs you really have to be careful and discharge any static electricity you may be carrying by touching the case before handling even with the power off. Double check all your power connections and especially the logic cables going to the harddrive. It seems to me that one of those connections is not quite right. Good luck. and God bless.

Asus p5nd motherboard won't start when power button is pushed, but the motherboard light stays on..

Most probably your power supply. An SLI rig will draw a lot of power for the graphics and for a power supply in a system like this to have lasted 5 years is amazing. They don't last forever. You could buy a PSU tester (about 10 GBP) and confirm it. But if you have to buy a new one look for one that is at least 25percent more powerful than your old one and has at least a bronze efficiency rating. (silver would be better) and buy one from a known brand such as Antec, Chillmaster, or OCZ.

My computer keeps shutting down after a few minutes. I have replaced the powersupply as well as the cpu fan. I am being told now that it is the system/motherboard. Is that an accurate answer?

When the CPUoverheats it goes into thermal shutdown and will not boot up again until theCPU has cooled down.
The heat sink may be clogged with dust, which causes the CPU to overheat byreducing air circulation through the heat sink.When you replaced the CPU fan, did you put new thermal heatsink paste on the CPU/heatsink? If not then the CPU can overhest. Your computer fanmay be faulty and not spinning freely, in this case replace the fan.
Check the fan and heat sink assembly and remove the dust, loosen the dust anduse a can of compressed air to clear away the dust.

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.

Try to put a separately vga card if you worked with the internal one from the motherboard. The atx may have blew it up.

Suddenly pc restarted.

Your CPU is overheating
1) Turn off computer and remove case side
2) remove fan from "heatsink" do NOT remove Heatsink "Usually this is stuck with solidified heat paste"
3) clean all dust and dirt from heatsink and fan.
4) vacuum out case Include behind power supply and video card.and any other fans
5) use stiff brush and vacuum outside of power supply
Reboot and see if still restarts if not everything OK
shutdown PC and refit case side.
This is a common problem on a lot of computers as the environment they are used in is usually dusty.
I do mine every 3/4 months and have no problems like this
Please when works give me a fixya

Remove case side and clean out ALL fans then remove fan from heatsink DO NOT remove heatsink (probably stuck on CPU) clean all fluff and dust from heatsink.
Use a stiff brush and vacuum cleaner on power supply fan area
then vacuum out case include all vent holes and behind power supply. test start.should be OK

If the CPU is dead the problems can be
  1. no power
  2. no fans etc or
  3. power, no beeps (errors)
If the Ram is not compatible it would be constant beeping.

With the board in, and power supply 20pin + 4pin Pent 4 power attached,(#2 and #7 of motherboard layout) remove power cord from power supply.
CLRCMOS0 allows you to clear the data in CMOS. The data in CMOS includes
system setup information such as system password, date, time, and system
setup parameters. To clear and reset the system parameters to default setup,
please turn off the computer and unplug the power cord from the power
supply. After waiting for 15 seconds, use a jumper cap to short 2 pins on
CLRCMOS0 for 5 seconds. Remove the jumper. Remove heatsink and fan from CPU. disconnect cpu and reseat it. Re-install heatsink and fan. Plug in the power cord. Try to boot up. If it still does not boot and (no power, no fans etc.) problem would then be cpu is fried.
