Why Your PC Stops Working
One of the most frustrating things in the world is getting up in the morning to see that your computer refuses to boot, or it keeps restart by itself. It was still working fine the night before, and you have totally no idea why it stopped working now.
In this PC troubleshooting guide, we will show you the possible problems that could happen to your PC and how you should fix it.
1. Your Memory Is Corrupted
One of the most common problem that I always encounter while troubleshooting a PC is that Windows stops working inexplicably at random intervals. Most of the time, it is the memory RAM causing the problem. The easiest way to verify this is to swap the RAM cards in your PC with some spare ones and test to see whether this works or not. Of course, if the RAM cards aren’t easily accessible, you can run memtest as an alternative. Corrupt bits of memory can cause a computer to act funny, and even crash, every time it starts.
Solution: The only way to solve a memory problem is to replace it with new memory. You will most likely end up replacing all of the memory sticks (usually two to four).
2. Switched Boot Order
When you can’t boot up your PC, it could be due to a switched boot order where the system cannot find the partition to run the bootloader. This usually happens when your CMOS battery (a small round battery found on your motherboard) runs out of juice. It could also happen if you (or someone else) have accessed the BIOS recently and changed something accidentally. You’ll know your boot order was switched if you get the “no operating system found” error when starting your computer, or something else besides your operating system’s loading screen.
Solution: access your BIOS (press “F2″ or “Del” button when the BIOS screen appear) and reconfigure the boot order. Your boot order should look like this:
If your configuration already looks like this and it still cannot boot up, check your CD ROM and eject any disc that are in it, then restart.
