Have you tried safe-mode for a start?


These links may be of more help/use...?

monitor wont turn on as the ports wont work even though before they did, so therefore i cant do safe mode (this is a custom build btw)

To test the system a little-perhaps...

Download and burn a Linux ISO - current flavours include Ubuntu, Puppy Linux - and Zorin. Ubuntu is a standard Linux variant; Zorin seems to be an interesting one - which allows assorted options re' desktop appearance... (at least from what the web-site describes).


Burn the ISO to a DVD; boot with the DVD.

If it boots OK to Linux - as in you can see a display - it's a start? Linux boot/installs itself into RAM only...

Incidentally what happens if you try to get into bios settings (and have a look-see in there at settings various) - even though ports don't work when trying to boot into win-8.1? Presumably you have an idea of what the F key is for that with your bios?

Also double-check all internal connections; and cards are securely installed - perhaps remove each and re-insert/reseat firmly?

you cant do a lot of testing with no monitor working if it shows no signal that could be a bad video card you always try plugging it into on board video if you have that but if not check your connections video and power also to monitor

Since it is a custom machine, how about some details?
List all components including make and model numbers.
How long do you have it? How long did it work correctly?
Who built it? You? Friend? Store? Online purchase?
Does anything show in the monitor? During Post? During part of Windows start up? What color is the monitor power light? Is there a No Signal indicated on the monitor?
Are there any beeps or other sounds? Fan Sounds? Flashing lights? Power light and/or hard drive indicator?
Any BIOS access at all?

You have to be a little bit crazy to keep you from going insane.

It says Entering Power Save Mode, which I can assume means No Signal. I don't understand as it worked the night before and the next day it doesn't.

My GPU isn't plugged in. If anyone has an idea thanks. I'll see if any wires are loose

Here are my specs, and I built the PC (first timer):
AMD A6-6400K 3.9GHz Dual-Core Processor
Asus A55BM-E Micro ATX FM2+ Motherboard
G.Skill Value Series 4GB (1 x 4GB) DDR3-1333 Memory
Western Digital RE3 500GB 3.5" 7200RPM Internal Hard Drive
PNY GeForce GTX 650 1GB Video Card
EVGA 600B Bronze Power Supply
HP 24X Multiformat DVD/CD Writer
My case is: HEC Vigilance MicroATX Mini Tower Case
Also, my HDA wire in my case doesn't reach my Mobo and I recently discovered my Mobo speaker was broken so I can't hear POST. If someone can list things I can do.

If the display shows "Entering Power Save Mode" - at least the monitor is working.

You need to somehow re-enable/renew the internal speaker; the (audible) POST signal would be very useful to have - as a possible indicator as to what's amiss...

If the HDA cable isn't long enough can you not secure an extension for it? ( I have to admit I had no idea what an HDA cable is - until a wee trawl via Google...; must be getting olde...)

An alternative and temporary measure - If you can get hold of a very small speaker, and solder, or with croc-clips, attach two wires to it and then "croc-clip" the other ends to the speaker terminals on your broken internal speaker, that may at least allow the POST signals top be heard? Even a small ear-piece as used in transistor radios (remember those); or any standard/current mini-headset (ipod/ipad etc.) ear-piece will do likewise; simply clip a wire to the tip and one to the larger (barrel) ring on the mini-stereo plug; and the other ends as above to the internal speaker connections...

Standard (the larger size) earphones will do equally well...; and may be easier to clip to?

Somehow you need to hear those POST signals...?

Do any indicator lights "light up"; as in power indicators, hard drive activity - even in only briefly?

Have you checked the volts out of the power supply (they are know to to fail on occasion - and even more so if working hard/close to the their stated limits/specs.)?

Also - very basic I know- but have you verified that the mains-cable into the case is actually OK - that it delivering standard 120(?) volts into the case?

Also is there an on-board fuse (mains rated) anywhere' - typically it may be within the psu housing? Similarly any on the motherboard...? When last I bothered to build a PC there were such useful items easily viewable and verifiable...

Meanwhile - and a tres long shot and almost not worth considering - but - what happens if you remove the plug-in graphics/video card and try a boot up?

Until you get the POST signal info. you are really feeling in the dark for a black hole...? Although a volts check on the psu etc. may provide some info?

Based on info thus far - it has a feel of a psu problem...; if the graphic/video adapter is OK?

btw - what is a GPU - as in My GPU isn't plugged in.?

The front of my case has two lights, Power, which turns on when the PC is turned on, and HDD, which I noticed only turned on when my PC was working

Are they both indicating - lighting up; the power of course "steady" and the HDD possibly blinking on/off as/when being accessed etc.? The HDD light would be blinking etc.during attempts to boot up too...

Also if the HDD is active (especially at boot up) then likely you would hear it - especially if the case/cover is open and you are able to listen more closely?

im not sure if i can hear it but ill unplug a few things, and no light whatsoever on the HDD light on my case but as for the light that says System (or power) it does light up

mmm - do you have a volt meter? If so can you disconnect the HDD (fully powered of course when you disconnect), and then powered up again - check if there are volts getting to that connector...?

This is where to find the manual for your motherboard; and when downloaded etc (if you don't have it already) page 1-16 is where the volts various are indicated...

Possibly you can check all the volts are as in the manual?

i dont see a volt meter anywhere, and i think the voltage is fine, as like i said it was working and everything, even with everything connected.... this is quite frustrating as i've spend a lot of my savings on this, and it won't be possible to sell it. ill try your method
edit: hard drive is working, i can hear the disk starting up when i plug the power in

mmm referring to a volt meter; that meant do you have one? One buy from RadioShack for a few dollars - viz:


I've had one of similar to this from RS for years... Very useful item to have...

You need to confirm volts are OK of course... And also confirm the cable from PC to monitor is OK... The cable is frequently the last point of concern for many... and much time can be wasted looking for faults that aren't due to anything other than a failed cable... If the cable is "tied" to the monitor.. either test the/your monitor on another working computer; and/or test your PC vga o/p with a known to be working monitor?

And again try and restore some kind of monitoring of the audible POST signals...

ive used 3 different cables for the monitor, but let me try a different monitor, and keep in mind as well its ALL the ports in the pc, not just vga

How do you know it's "all" ports - if no display to indicate what etc?

The only port that would be obvious at boot up - would the vga o/p; and if that was OK then the keyboard/rodent might also indicate appropriately (OK or not) via on-screen responses if used to access bios, F functions etc.

Appropriate beep(s) would show if keyboard/rodent were or were not working OK. If there was a working display then efforts to successfully (or not) access bios and even the F2, F8, F12 etc. functions in general would soon be apparent if the keyboard was/wasn't working... - even if no audible monitoring of the beep codes...

USB wouldn't be available unless you have a board with boot-up usb support (and it's enabled); which if this a current board - would of course be the case?

when i plug in a keyboard + mouse they don't turn on where as previously when the monitor did receive a signal and the HDD light turned on they both worked, and i also was able to use the front usb ports on the case

With the info in your #19 - power supply would be my first port of call (no pun intended); and also ensure that "all" connectors are securely in place.

And again try to get some form of audible monitoring of the POST...

Although if the psu is acting up.. even they may not be present...

So a voltmeter and audible monitoring may be most useful at this time?
