First make sure the power cable is plugged in to the wall socket and is switched on. If possible swap the power for one you know that works, if you have one. Make sure the PSU on/off switched to the on position. Make sure to connect your monitor cable to correct VGA socket especially if you have pc with dedicated graphics. If everything appears to be in order and the PSU is functioning as expected, we now need to look at the motherboard which may not be distributing the power correctly.
General Troubleshooting Support
Our aim is to guide you quickly and identify any potential fault with your PC and/or any components. You contact our online support team. Below are most common symptoms you can try.
Motherboard LED light
Most modern motherboards have an LED which indicates that power is reaching the motherboard. If this is off, then it's a good indication that no power is being received rather than inadequate power. If this is a new build, did you fit the motherboard onto motherboard risers?
Risers are supplied with new cases prevent contact with metallic surfaces in the case, preventing a short. If you have screwed the motherboard directly onto the case, you could have damaged the motherboard. If the motherboard LED light is on, we can assume sufficient power is being supplied to the motherboard. Make sure you have both the 24-pin ATX and 4pin/8pin supplementary power supplies securely connected to the motherboard, reseat if necessary. Check that the front panel “Power On” cable is connected to the correct headers on the motherboard. Everything appears ok with the connections and the PSU, then it’s looking like a faulty motherboard.
PC starts but there is no Display?
Check the graphic card is seated correctly in the correct slot and does the graphic card need power, if so is it connected?. Most modern cards require one or more 6/8pin PCi-e power connections so make sure the graphics card has sufficient power. If it has sockets for two power connectors, both must be need plugged in.
Are you using the correct graphic port socket?
some motherboards have onboard graphics and are disabled if you are using a dedicated graphic card, make sure you are using the correct port If you can, check your system on another monitor and check the monitor cable too.
If you are replacing a graphics card, have you uninstalled the old drivers?
First remove old drivers from your PC then install the new graphic card Make sure you are using the latest drivers from the manufacturer’s website at all times. Drivers supplied with graphic tend not to be the latest or up to date. If you can swap the card back to the older card to see if this still works or swap for another known working one. If the problem is illuminated, then it looks certain to be a problem with the video card
Experiencing graphic problems with certain game?
It might be worth checking for driver updates and game patches. Make sure you use the latest drivers. If they don’t work, both Nvidia and ATI have archived drivers so try any older driver to see if it makes any difference. If problem only started since you changed the drivers, then it might be a good idea to either roll back the driver or re-install back the previous known working ones.
PLEASE NOTE: Unless you have a problem, avoid updating drivers on release. Keep an eye on the feedback for known problems before installing and try to avoid using beta drivers.
Check the RAM is properly seated and is making good contact with the RAM slots, if need to reseat the memory again.
Important settings for RAM is as follows:
Memory Frequency – The speed of which your RAM operates at in MHz. Latency or timings – The Latency is the timing for the RAM to respond between cycles. VDIM or Voltage – The voltage is essential for correct operation but make sure you apply the correct amount. If you over-volt your RAM, you will damaged the memory. The Frequency, Latency and Voltages are normally printed on the side of the modules. or try visiting the manufacturer’s website for recommended settings. Try running your system with one stick of RAM at a time and try each stick in different slots, going through each possible combination until you can pin-point the cause. Last but least try running Memtest86+ http://www.memtest.org/ to determine if your problem is RAM related, rather than PSU, Hard drive etc.. Memtest86+ is a superb free utility that performs a series of tests to check memory stability. If there are any problems with your RAM or addressing RAM, then Memtest86+ will tell you.
Hard Drive Not Working?
Check that your hard drive is connected correctly and securely to the Motherboard. The connections used on sata interfaces are known to become dislodged due to transportation. Try a different port or a another data cable.
Symptoms of a failing hard drive would be?
No operating system found or system no longer recognises your drive. Strange noises, grinding noises which are potentially a disk head crashing or crackled bearings. Random computer crashes and restarts. System is generally slow and unresponsive.If you think the hard drive is failing you can go to the hard drive manufacturer website , they will have a diagnostic utility to determine drive failure. If any errors are reported, then the hard drive will be faulty. Recovering data from a failed hard drive is unlikely, however there are specialist companies that can recover data from failed drives but at a cost to you. Hopefully, you would keep a backup of your data.
The PC starts but then emits a series of bleeps?
The series of bleeps corresponds to an error code depending on the manufacture of the BIOS. Make a note of the short-long bleeps and cross reference them with either your Motherboard manual.
Common faults are:
RAM not inserted correctly, not working or is missing. 2. CPU Fan not attached or undetected – Make sure you have attached the CPU fan to the CPU_FAN header or adjust the 3. Settings in the BIOS. If the fan is rotating less than the expected warning value, then you will get errors. 4. CPU not detected or not working. Has the CPU been installed correctly 5. Video card not inserted correctly or is not working. Make sure the card is inserted correctly and has the right power 6. Connections if applicable.
My systems supposed to be Overclocked
If you are unsure If your computer is running at it's Overclocked speed the instructions below will enable you to check to see if is running at the correct speed. The windows system properties will usually only read the standard CPU speed not the Overclocked speed. To check that you computer is Overclocked you will need to download some programs so that this can be checked. The first program that you will need to download if you haven't got this program already is CPU-Z. This program will monitor all aspects of your system and will report them in a user friendly interface. The second program that you will need to download is a program called Prime 95. This is a stress testing tool that will put your CPU under 100% load so that the Overclock can be read accurately.
