reboot - Windows 8 uptime not resetting after restart or shut down

Memory continuously rises, probably because of various applications that I run including Chrome, and it starts to choke out windows so I try to reboot it after 3-4 days at the most.
When I am in the Task Manager after a complete cycle (shut down and start up) it shows 5 days 7 hours 30 minutes and some seconds. Also, Memory is at 2.9 GB after a restart, is this normal?
What kind of issues is this going to cause, other than I can't tell exactly how long it has been between cycles (restarts)?
How can I fix this issue?
I am running Windows 8.1 Pro. I have been trying for about 30 minutes to search Google for this issue and possible solutions but "uptime" is quite the ambiguous word.

This seems to be connected to what @LightBulb said. In this thread the second post mentions:
this happens becasue of the new Shutdown/Boot mechanism from Windows 8 which is basically a logoff + Hibernation. [sic]
He also links this msdn blog, where I found the following:
Of course, there are times where you may want to perform a complete shutdown – for example, if you’re opening the system to add or change some hardware. We have an option in the UI to revert back to the Windows 7 shutdown/cold boot behavior, or since that’s likely a fairly infrequent thing, you can use the new /full switch on shutdown.exe. From a cmd prompt, run:
shutdown /s /full / t 0to invoke an immediate full shutdown. Also, choosing Restart from the UI will do a full shutdown, followed by a cold boot.[highlight by me]
Summary:
Shut down does not reset the CPU cycle! If you want to reset the CPU cycle (and thus uptime), use the Restart option or run shutdown /s /full instead.
@Daniel B has provided yet another alternative. When shutting down via UI, press Shift when you click. When using that trick with "Restart", you get the "Advanced Startup Options" screen.

I have a high-end dual CPU workstation that has started rebooting itself several times per day. It has no history of doing this - it just started in the last few days. It hasn't had any hardware updates, or even had the case opened recently.
There is no blue screen/STOP error and nothing in the Windows logs to indicate a software/OS error. There is no "your computer recovered from a serious error" message or prompt to start in safe mode.
The only pattern is that the restarts increase in frequency through the day; maybe staying up for a few hours to begin with, then restarting every few minutes at the end of the day.
So I am thinking its some hardware part wearing out, and the increasing frequency leads me to think its temperature related.
So, if I was to start swapping parts out, what should I start with, i.e. the most likely culprit?

My wife's laptop had a similar issue recently. We opened it up and reseated all of the cards and cables. That fixed it.
Open the computer, pull out a cable and put it back in again, then do the same with every other cable and card and memory stick. Also give it a gentle vacuum or dusting while you're in there.

Turned out it was blown capacitors on the motherboard and/or in the power supply. Good description of the issue here.

Sometimes...... If a PC reboots itself and does not go into the blue screen or BSOD even though the OS is set up to display the BSOD, it may mean the power supply is failing. In other words, the PSU does maintain the proper voltages in order to maintain the system long enough for the BSOD to post.
