1. Your computer isn’t turning on? “Oh, no!” You think, “I’d better get a new one!” STOP right there. Before you get too frustrated, be sure you have checked that the power cord is actually plugged into your wall socket properly. You may think it sounds silly, but believe me, it’s more common than you think even for the computer savvy. If your computer is connected through a power board, you should try plugging it directly into the wall (note for the safety conscious: by plugging the power cable directly into the wall, you lessen the chance of power failure and damage to your machine). Another reason that your PC may not start is if you have made any repairs or modification to your machine. You may have unwittingly pulled out a connect plug; check all connections.
2. If your computer is starting but is spitting error messages at you, then you might need to take out any memory modules such as RAM and then reset them by plugging them back into different RAM slots.If you get an error such as ‘Unexpected Interrupt in Protected Mode,’ then there is a problem with the settings you have entered in BIOS. To fix it go into BIOS and set it to default settings. If the problem still won’t go away, then you must remove the CMOS chip on your motherboard then put it back in to clean BIOS completely.

Jason What, exactly, are supercomputers? The clue is in the name, really: they’re powerful computers capable of calculating many millions of floating operations per second (FLOPS) essentially, they’re very, very fast.
While any array of powerful computers, such as a modern-day web server which consists of several motherboards (the main circuit board of a computer) running in parallel can be considered a supercomputer, generally the term is reserved for machines that dedicate their entire hardware to one complex task at any given time.
Take the NEC Earth Simulator in Japan, for example, which was created specifically for modelling weather problems associated with global warming. Or the world’s fastest computer, BlueGene/L at Lawrence Livermore National Laboratory in the US, which simulates the behaviour of biomolecular structures and protein folding. It’s capable of 600 trillion FLOPS (tera-FLOPS or TFLOPS), whereas, the six-year-old Earth Simulator is only capable of 36TFLOPS. BlueGene/L won’t hold the top spot for long, though. Supercomputers twice as powerful will be online soon. Read More»

Jason Just thought I should give the community my top five list for computer troubleshooting!

Windows Product Activation (WPA) is Microsoft’s way of keeping you from installing a copy of Windows Vista on more than one computer. It basically marries the copy of Windows Vista you’ve purchased to the computer’s hardware it’s installed on.
The WPA Process
When you enter the product key three identifiers are generated and collected:
* Hardware ID: A unique identifier that’s generated from information gathered about the computer’s hardware.
* Product ID: A 25-character unique key supplied when you purchase Windows Vista.
* Installation ID: An identifier Windows Vista creates from the hardware ID and product ID. Read More»

One of the easiest ways to boost performance for any PC is to add memory to the system. But before you go to get that memory upgrade, be sure to gather information about your computer to ensure you get the right memory for your system. You need to know what type of memory the computer uses, the memory module sizes and what already exists in the system.
How Much Memory Do I Have?
Find out how much memory is in the computer by examining the BIOS or operating system. For Windows, this can be located by opening up the System properties from the Control Panel. Also open up the case while the computer is off and find the memory Read More»

Here’s another tip for speed demons, determined to shave the last few nanoseconds off their Windows XP boot up times. Truth be told this one probably won’t save more than a second or so but every little helps. The idea is that XP wastes time and resources checking to see if there are any devices connected to empty IDE slots on the PC’s motherboard. Read More»

One of the most frustrating problems to troubleshoot is a random one, one that doesn’t seem to have one specific cause. The key to troubleshooting such problems is to remember that the symptom is not always directly indicative of the cause. The program or utility that it locks up on is not necessarily the issue.
Suppose Windows starts normally, but then starts crashing, freezing or giving serious error messages shortly afterward. Many times running Scandisk (or Check Disk in Windows 2000/XP) will solve the problem. That’s because such problems are often caused by errors in the FAT or NTFS file system, and this utility will fix them. In Windows 9x/Me, choose Start, Programs, Accessories, System Tools, Scandisk. In Windows 2000/XP open My Computer, right-click the drive and choose Properties, and click the Check Now button on the Tools tab. Read More»

Weblog J2s site has put together a hardware list capable of running Vista in all its Aero glory for just over $500.
This setup should run Vista and pretty much any regular application you need (it won’t necessarily be ready to do anything but light gaming, but hey – we’re not all gamers). All you need to do is put it together. Luckily, we’ve covered almost every step of building a PC here at pctipsbox, from installing your motherboard, CPU and RAM to your hard drives, PCI cards, and power supply. Read More»

BIOS Backup: Sometimes the BIOS program on your motherboard can become corrupt and your PC will not function properly. So, you need to always keep a backup of a good version of the BIOS on a floppy disc. If something ever goes wrong with the BIOS, you can flash (overwrite) it with your backup. The software used to backup or flash the BIOS is usually available on the motherboard driver CD or on the motherboard/BIOS manufacturer’s website. Refer the motherboard manual for step-by-step instructions on using the BIOS flash software.
