comment Display not working even after trying new graphics card
Only reason I asked about PSU is some don't officially support the sleep state requirements for Haswell CPUs. But as you say if it's a new problem, and you rule out everything else, I guess it leaves the motherboard as the most likely cause. Hardest part to test though unfortunately :/

comment Display not working even after trying new graphics card
Hmm...when the problem occurs, do you see that BIOS/motherboard splash on reboot, or nothing at all? What is the power supply, and do you have a spare you could try? Have you tried unplugging everything but the bare minimum (a faulty drive, for example, can sometimes cause the weirdest things to happen).

comment Display not working even after trying new graphics card
What is the motherboard and graphics card make/model? It could be a physical issue with the PCIe slot on the board, or if the GPU needs PCIe power from the PSU, maybe that connector is faulty?

comment Computer stalling out during gaming and randomly restarting - I think its the power supply. New power supply's don't work?
Fans going crazy and random restarts sounds like it could be temps. Run HWMon or something to check them.

comment Assembling a desktop for the first time, require advice
@Mast: Sure, hence why I said "if dual-booting gets annoying" and "in my experience". Sometimes you need a native install, but I certainly wouldn't dual boot if a VM was a viable option for whatever task I needed to do.

I find the RAM manufacturers have more comprehensive compatibility lists than the motherboard manufacturers. For Kingston look here: kingston.com/en/hyperx/certifications

comment What is the reasonable choice of memory for DZ77GA-70K + Intel 3770K nowadays?
Not sure how this question was interpreted as merely a shopping recommendation? Surely the dot points imply it is looking for analysis on how to choose suitable RAM? "Reasonable choice" doesn't necessarily mean "tell me an exact model".

comment DDR3 SDRAM compatibility: clock speed and timings
Ah, it's a laptop. With desktop motherboards DDR3 incompatibility is relatively rare, and in general will downclock to something they can run, but I don't have enough xp with laptop boards to answer. Following the manufacturer specs -- as you're already doing -- is your safest option.

comment Symlinks over SSH: Why am I unable to access files/directories in parent directory if traversal to current directory was through a symlink?
I cannot reproduce what you're seeing. Are you sure you created a symbolic link (using ln -s)?

comment Virtualbox shared folder mounting not working
May not be able to help much more as I can't reproduce that problem. There are quite a few suggested fixes for that error around the net though. Maybe have a look at superuser.com/questions/725240/… and stackoverflow.com/questions/3492466/…, see if any of the suggested fixes help?

comment Virtualbox shared folder mounting not working
Can you edit to show the full mount command you're using? Have you shared the directory you're trying to mount from the host side? When you say "insert guest addition CD", you then successfully ran the install scripts located on the (virtual) CD, right?

comment Black Screen CPU & GPU running and fans spinning
@Mothermole1, efficiency works the other way around. The rated wattage is what it can supply internally, but the efficiency means it will draw more from the wall.

comment Why does my CPU not use it's full TDP wattage potential?
I guess the thing to make clear is that while people often use TDP as a handy ballpark for how much power a CPU might consume, it's not actually a power consumption rating.

comment No Video Output - No beeping - Asrock H97 Pro4
I think you will only hear beeps if you have an onboard speaker plugged in (like one of these: cdn.overclock.net/b/ba/ba4225be_speaker.jpeg). Otherwise there's nothing to make the beep. Try a different stick of RAM if you can.

comment What is the risk of reusing my PSU?
@ilkhd: no, not usually. But without knowing the quality do you assume the best or the worst? If the new machine needs 700W as David suggests, will the old one handle it?

comment What is the risk of reusing my PSU?
David, it might also help if you can specify what parts will be in the new machine. A 50W dual-core using onboard graphics is a lot different to a gaming machine with a 300W+ graphics card. In particular, if you are intending to run dual cards, I would be very wary.

Here's a good article at Hardware Secrets that touches on some of the issues: hardwaresecrets.com/printpage/…

comment What is the risk of reusing my PSU?
I imagine it would be pretty rare to actually go bang or anything at normal loads, but as the capacitors age I believe the quality of the power they can deliver (regulation, noise/ripple) as well as the total maximum power will be reduced. Poor quality power may subtly damage components over time or cause instability in the system. (At least, that's my understanding. I'm no expert on PSU internals or elec eng).

comment Building a computer, no output from on board video after power up
Can you list all the parts in the machine? A dead power supply is a strong possibility as well. Have you tried it set up outside the case (with motherboard on a non-conductive surface like wooden tabletop or cardboard) to remove shorting as the problem?
