Hi All,
I have always used VMWare on my laptop for studying purposes. The laptop runs an i5, 6GB RAM and standard HDD. It has performed pretty well overall for running 1-2 servers and a client over the last few years, but as you can imagine, it's at its limits!
I have picked out a new machine running an i7-4790, 32GB RAM, 256GB SSD with a 2TB HDD. It will be running Windows 8.1 Pro and as far as I can tell, the OS and spec support all the requirements to run Hyper-V.
I am aware there are only 8 threads on the i7, but this machine is only for study purposes so the machines won't be running anything too heavy and only running perhaps 3-4 VM's at once. How will the machine stack up? I know it will be a massive improvement in comparison to what I have now, but I don't want to spend out and then find there is a bottleneck holding me back!
Thanks

Is there any way to test a PC power supply under load without hooking it up to actual PC parts?
I have a power supply tester that shows the voltages coming out of the supply, but it does not place an actual load on the supply.
The difficult we do right away...
...the impossible takes slightly longer.

PC power supplies require a minimal load to source output voltages inside the specification range. Some will check if a load is connected and switch off outputs with no load. So each of the 3.3, 5, and 12 V rails should be connected to some kind of load.
For the 5 and 12 V rails I would use an old drive (floppy, CD/DVD, or hard disk). The 3.3 V rail can be connected to a load resistor (e.g. 3.3 Ohm, 5 Watt). Finally you must connect the Power On signal (Pin 16/14 for ATX-24/-20) to GND.
It might be necessary to connect an additional load resistor to the 12 V rail because the load may be not enough when the motor of a conncted drive is not running.
Additional information can be found at the Wikipedia[^] page (see also the links at the bottom).

You will need voltage meter for this.

My mouse clicks are disappearing.
i.e., I click, and sometimes the machine (or website) responds as expected, sometimes there is no response.
Concurrent observation: My keystrokes are frequently delayed.
i.e., what I type appears on the screen, but delayed.
Other concurrent observation: Some of the mouse clicks are delayed, while others just don't occur.
Who's the most likely culprit ?
Worn out mouse ?
Driver in Windows ?

It has a bright red LED on the bottom side to do the tracking.

Take a look at perfmon.exe (run it as an admin), and find out if some processes use up a non-adequate amount of resources (processor, harddisk, memory).

Run pc in safe mode if working well there then it's driver problem.

After 3+ years of living without any printer in my life, I believe that I should acquire one again.
Interesting market changes; seems like ink jets have made significant headway in the market over the lasers. Yes ? No ?
At the moment, my knowledge comes only from the marketing departments of the manufacturers and retailers and their obfuscated/distracting websites; so I remain the student.
I'm thinking cost. Last I remember, a page from an inkjet could easily cost 10 or 20 times as much as a similar page from a laser printer.
With beautiful color printing, the cost could hit a dollar or two per page.
However,,,,,,,,,,,
These measures and estimates were done a decade ago.
Anybody who knows about these things as they are in the Summer of 2015, please chime in.
What questions do I want to ask ?
What do I want to know ?
What are the marketing departments NOT telling me ?

I've always just used an ink-jet all-in-one and called it good. I used to buy HP, but the materials seem flimsy now, so my current device is from Brother. There are some things that just aren't worth spending a lot of time thinking about. Go to a store that has a bunch on display and choose one.

Do I want a combination Modem And Router ?
Or,,,,
Do I want a modem, and a router, in two separate and distinct boxes ?
I'm 99.99% sure that I want to do as much as I can with wireless connection(s).
|

Unless you foresee a change in line technology, I'd go for a combination. One less box to worry about. I have had a couple of ADSL modem + 4 port router + wifi boxes, and they do just fine. 3 wired ports in use and about 6 wireless devices. Whatever you get, make sure you lock down the admin access.
Cheers,

Go for the two in one option if oyu have a choice.
I don't have a choice as my ISP provides me with a fibre router(fibre cable in and one cat5 out) - I run a router/gateway off that.
My main computers then run off the gateway via Cat5 and I also have the wireless, on the gateway, switched on so that I can use mobile devices around the flat.

I want to build an x86 system for Windows, and possibly Linux as well.
Last time I did this was years ago, so I may need some education on what's happened to the trade since then.
I want three monitors on the system.
I look at the specs on various motherboards, and don't see anything about the number of monitors they will support.
I do see the specs listing audio configurations (e.g., 5.1, 7.1, etc.) but I don't see a word about the video.
So, what am I looking for ? What do I want in terms of a motherboard ? What question(s) do I ask ? What will the spec say to alert me to a yes/no when considering a certain motherboard ?
Do I need to buy a separate discrete/distinct video card ?

A low-end motherboard will usually have onboard video capable of supporting one monitor. However, higher level motherboards will not have onboard video. For them, you must purchase and install one or more graphics cards.

Thanks Richard, good to know.

Motherboards normally only support 1 or 2 monitors, one on VGA and the other on some digital. If you're going to run 3 monitors, seriously, forget on-board video. It usually sucks ass. You're going to get a separate video card.
You start with which CPU you're going to run, then you go to the motherboard and RAM. Which one you get depends on what you're going to do with the thing and whether or not you're going to tweak the chipset to eek out every bit of speed you can get.
On my rig, I have an Asus P8-P67 motherboad and run dual GTX770's, and (3) 24" monitors.

Thanks Dave, Good stuff to know. Glad to get these words now instead of later !
I would like to post my anticipated parts list as a reply to this message, and if you care to comment, thanks; particularly if you see any big-time stupid moves shaping up.
I get the feeling I'm leaving out something minor, which will produce a major annoyance when I try to execute the assembly of all this.

Not bad. Should run at about 220 watts under full load. Your video card draws half as much power as mine does.
My machine tops out at 480 watts and, yes, it alone heats the room to toasty temps.
You might also consider getting some Arctic Silver to put under the cooler if it doesn't come with thermal paste.

You have to buy separate graphic card with multiple outputs.
|
|
|
|

I built a system using a workstation motherboard (ASRock C226 WS) and it supports 3 monitors but the connections types are all different - 1 each of DVI, HDMI and DisplayPort.
It relies on the on-chip graphics capability in the Intel processors to do that and needs no separate graphics cards.

i have local network in that i do have different Switches. Now i want to know the sub switch mac address interface wise in main switch.
190 main switches
3000 sub switches connectivity.
if any body provided solution that would be very much helpful for me.

I am no expert in these things. But I do know that I can read such properties from the Networking interface, or from the Device manager (if you're having Windows). Otherwise, you can always check for the Mac address for your own system (Read the manual?)

What i am trying to do is to get the firewall to force outbound traffic to use a proxy-server on LAN machine 1 if the WAN-IP is in a certain range and comes from Machine 2,3,4
in effect i want to put all google traffic through a proxy-server before sending it out again.
I am told that NetFlow on a cisco router might be the answer but after reading a little bit more it seems to me that netflow is about reporting on data and not directing data.
pfSence I've tried but it would not install and i want to use a router/firewall much like the Draytek i used today that offers this type of option.
A Nice to have would be a box that can do DPI on SSL by using a fake CA-Certificate and man-in-middle but thats not quite so important.
I know nothing about IpTables so a router with a web-interface would be nice so what one should i buy ?
