Just When You Think You Have it Perfect

It all started with this, my awesome keyboard. Three weeks ago, the Logitech bluetooth receiver decided to go bad on me, leaving me with no keyboard other than a 8 year old Microsoft PS/2 model which I’m surprised still has more than half of the keys working.

Just prior to this time, my motherboard’s PCIe-x16 slots went out as well. Luckily, ASUS has a relatively no-questions-asked Warrenty Exchange policy and I shipped it out for an exchange. It just so happens that I had a brand new Intel motherboard sitting around which I was planning on using for a secondary machine which would, in turn, become my server. I installed my Intel board, and with a quick reactivation of Windows, I was on my way. Then, the keyboard receiver gave out.

Unfortunately, the Intel motherboard doesn’t have any PS/2 ports, which left me without a keyboard for around 24 hours. I quickly picked up a $10 wired USB keyboard from my local Best Buy. I then proceeded to call Logitech and, once again, ship out the bad receiver for a no-questions-asked warranty exchange of the receiver.

Two days ago, the receiver arrived in the mail and I was quite ready to get rid of that horrible wired keyboard and go back to the diNovo Edge. My ASUS motherboard also arrived. Upon plugging in the receiver to my computer, Windows seemed unable to locate any drivers for the device. This was rather strange considering it shouldn’t need any drivers and the fact that Logitech doesn’t even provide any.

After a lot of diagnosing and registry tweaking, I determined that somehow, somewhere, the malfunctioning USB receiver corrupted some driver somewhere on my Windows installation and I for the life of me couldn’t figure out how to reverse that damage.

I also recently decided to upgrade from a total of 380GB of HDD storage to 2×500GB drives for a total of 1TB. Given the current events, I thought it best just to pull my old hard drives out, switch back to my ASUS motherboard, throw in two brand new drives, and reinstall Windows completely. I begin this process at around 11PM. Formatting my new 500GB HDD took around two hours first.

Three hours later (that’s 2AM), I’m back in Windows Vista x64 and everything seems to be working perfectly, including my diNovo Edge keyboard.

Oh boy was I wrong.

An hour into installing all of my commonly-used applications (now 3AM), and right in the middle of formatting the secondary 500GB hard drive, my computer suddenly shuts itself off without warning. There was no crash. It was as if someone pulled the power cord out of the wall.

I think to myself, that was odd, and reboot the computer. Once again, I come back into Windows and all seems to be running fine for about 5 minutes when it happens again.

At this point, I start thinking that my BIOS settings are messed up or I didn’t install the CPU’s heatsink on the motherboard properly so my CPU was significantly overheating and shutting the unit off. Upon going into BIOS and looking at the hardware monitor, I discover that, indeed, the CPU is running farely warm. About 50 degrees Celsius too warm for idling. I instantly think this is the cause of my issues, so I remove the heatsink, reset the processor, and reattach the heatsink. (now around 4AM)

Now, the problem I faced at this point was two-fold. 1) The thermal compond was a bit old and needed to be replaced and 2) the brackets which latch the heatsink to the motherboard were worn and the heatsink wouldn’t set tight enoguh on the motherboard. I decided that, considering it’s 4AM, it would be best I go to bed and continue this journey in the morning.

Bright and early (that means 10AM for me), I wake up and take a drive out to run a few errands, including picking up a new heatsink and fan. I decided that while I’m out, I might as well buy some external hard drive enclosures in order for me to easily transfer the data off of my old HDDs to my new ones. I also picked up a brand new computer case which would help with cooling significantly.

After driving a total of 75 miles all over the city of Tampa just to find stores that have what I need in stock, I arrive back home around 3PM and begin assembling my computer from scratch as I now need to switch cases.

Around 4PM, I finish this process, plug my computer back in, and, to my surprise, it actually boots the first time. The CPU is running extremely cool as are all the other components thanks to the new case. Windows sees that there was a problem shutting off previously (no kidding) and proceeds to run chkdsk on the primary partition. However, about 10 minutes into running chkdsk, it suddenly locks up and does absolutely nothing. I rebooted the computer, and again, experienced the same thing.

At this point I’m just about to lose all self control. I say to myself, “Screw it” and reformat and reinstall Windows once again. Two hours later (around 6:30PM), Windows is installed and I proceed to install drivers. To my despair, halfway through this process, I lose all power to the unit just like before.

I was at a full and complete loss for what to do next. I thought I’d tried everything … until I noticed one key issue.

The fan on my power supply wasn’t spinning.

As it turns out, the issue with the power loss was because the power supply (not the CPU) was overheating and shutting down automatically. This was ridiculously odd considering I have only owned that PSU for around a month.

I rebox it, and head back to the Best Buy where I purchased it and get an exchange.

To make a long story short (it’s too late I think), just over 24 hours later, my computer is back up and running perfectly smooth.

Let’s hope it stays that way for a VERY long time…

I Love Networks

It’s no secret. I’m a geek.

I’m also a networking geek. Basically, that means I get all warm and fuzzy inside when I work with computer networking. I love it. It’s should be no surprise that I’ve chosen Network Administration as the field and career that I am currently pursuing.

Whether it’s TCP/IP, LDAP, DNS, HTTP, packet sharing, ports, firewalls, security, Linux, Microsoft Windows Server 2003, routers, switches, hubs, CAT5e, or anything else network related, I devour it. I love it.

The reason I love networking so much is because, well, it’s just so cool. I mean, come on. Even though it’s old technology, I just got a color LaserJet printer capable of connecting directly to a router. How cool is it that I can’t print to this router … by an IP address? How cool is it that I can do some port forwards on my router and actually print to my printer when I’m in another city and state?

Networking is what powers the internet. It’s what allows us to connect to any device I want and communicate with it. And its full potential has only begun to be realized. The future of networking is in the small things: like our MP3 players connecting wirelessly to our computers to sync music. Or perhaps, our MP3 players listening to music that isn’t even stored on the device but rather on a file server at your home hundreds of miles away. It’s what will allow us to watch TV from anywhere at anytime on any device we want. (Slingbox Pro anyone?).

I’m sorry, but networks are cool. Networks are one of the best examples, as well, for how following standards in the computing industry has gotten us places. Where would we be if TCP/IP wasn’t made a standard communication platform decades ago? The internet wouldn’t exist the way we know it today, that’s for sure.

What do you think of networks? Are they cool or do they scare the heck out of you because they seem so complex? Let me know. Leave a comment or Ask Me.

What is my computer?

Several people have asked me on what computer I’m running Windows Vista. I’m actually running Vista on 2 of my own machines, both my laptop and my desktop; but my desktop has become my primary machine.

One particular person asked which type of computer I use. For my laptop, I have a Toshiba Satellite P105-S6084:

Intel Core Duo T2300 @ 1.66Ghz
2GB DDR2 800 RAM
160GB HDD

My desktop, however, is a custom built machine with the following specs:

ASUS Striker Extreme Motherboard
Intel Core 2 E6300 @ 1.86Ghz
2GB Crucial DDR2 800 RAM
Foxconn nVIDIA 8800GTS 640MB GPU
Creative SB Audigy 4 7.1 Surround Card
2×500GB Western Digital SATA 3.0Gb/s
1×250GB Maxtor ATA HDD
ASUS SATA DVD+-/RW Drive

UPDATE:

I recently upgraded my desktop quite extensively thanks to a bundled Intel package I got through working at Best Buy for a ridiculously low price (ie, 75% off). My new system specs are as follows:

ASUS Striker Extreme Motherboard
Intel Core 2 Quad Q6700 @ 2.66Ghz Each core
4GB Crucial DDR2 1066 RAM
2x BFG Tech nVIDIA 8800GT 512MB GPUs in SLi

This is my actual workspace. Pardon the photo being out of focus, my camera’s lens wasn’t behaving:
(Click here to enlarge) - 3.87MB @ 10.1MP

I converted my old components to a dedicated server with the following specs:

Intel DG33TL Motherboard
Intel Core 2 E6300 CPU @ 1.86 Ghz Each core
4GB Crucial DDR2 800 RAM
Foxconn nVIDIA 8800GTS 640MB GPU

The “Ask Me” Questions

As many of you know, I have an avenue on my site which allows you to submit questions to me, pertaining to technology, and have them answered. I have gotten quite a few, and answered almost all of them.

But some of the ones I get are either downright annoying and stupid, or outright hilarious. Heck, most of them relate to phpBB questions (which I don’t answer under any circumstances).

So here’s just a few of the questions I’ve received, starting with the most recent:

Titled “geography”

Where is india located?

Titled “haha”

ur funny and I haha’d

What the…???

Titled “phpBB”

OMG HELP ME IM BEING HACKED HE GOT MY PASSWRD

Hey, you, with the stuck caps lock button: I’m in ur base stealing ur IQ.

This guy thought I could help him with his physics questions:

Titled “physics”

Hey can you help me with my physics?

A baseball (m=0.15kg) is thrown with a speed of 30 meters per second at angle of 32 degrees above the horizontal. Neglect air resistance.

1) What is its momentum at the maximum height?
2) What is its momentum just before it strikes the ground?

wuts the answer?? Please its due tomorrow

What do I look like? A physics major? Well, I kind of am as a Computer/Electrical Engineering major, but regardless, I actually laughed at that one.

What is it about technology questions that people don’t understand? Hey, I’m all for the intellectual question that doesn’t relate to technology every now and then, and I’d be glad to deviate from technology, but why can’t they be real about it?

We’ll never know…
