Fixing the inside of Desktop tower

Problem: When I try to turn on my desktop computer, the internal parts make a beeping noise and windows OS does not start up. I was having this problem on Sunday.

Hypothesis: I removed my DVD drive and tried to replace it with a CD drive. The CD drive turned out to be incompatible with this desktop so I removed it and turned my computer back on when I started having the problem. all the cords are out of the way of the fan that cools the CPU. I don't know what is causing the problem. I just finished dusting out the inside of the computer.

Research: I tried to find troubleshooting information about the beeping sound in my user manual. No information about that. I inspected the inside of my computer and I don't see anything unusual.

Procedures: As I carried the computer to my room, planning to have it checked by a professional later, I heard something loose sliding around inside. I opened the desktop again. There was a loose washer sliding around. after removing it, windows was able to load again.

Results: Apparently the loose washer was sitting on one of the internal components, a chip or something. Extra metal on the internal computer parts hinders the ability of the parts to function. Keeping it clean and free keeps the computer working normal without a beeping alert.

Baselining




The reason why I should baseline is to make sure that there is no malicious or corrupt hardware tampering with the efficiency of how my computer runs.

I think the CPU runs normally. It's very steady when I'm not running processes. Memory is stays steady the whole time at 25%.


The hard drive spikes sometimes, but goes right back to normal at 0 KB/sec.

Printer issue

When I right clicked on the XPS printer icon in Printers, there was a message box when I clicked on properties that said, I should restart the system or the printer spooling. It was a weird experience, because when I printed a notepad with my name on it, a message box said printing 1 ... The printer didn't print anything that I noticed though.

Troubleshooting

Symptoms

While downloading music from Itunes, the computer crashed and there would be a blue screen. After restarting the computer and running the downloads again the same thing happened. But if I did anything else besides run the downloads, my computer didn't crash; only when the music downloaded.

Hypothesis

  • I need to run system restore to a point from yesterday to undo changes made by downloading Adobe reader today.
  • The internet connection is slow right now and I will have to wait until tomorrow when it is refreshed.

Results

  • After running system restore, system restore did not complete because of an unknown error. The same result happened after running system restore on many different restore points of different times. Supposing that the problem was from downloading a new version of Adobe Reader, I unistalled Adobe reader and restarted. That did not fix the problem.
  • While running the music downloads again, Itunes ran slowly enough that the connection timed out. Then if I tried it again the computer would crash. So I turned off my computer and waited till the next day when the internet was faster and by then the downloads finished without crashing the computer.

Solution

Either my computer was on too long and needed to be turned off so it could rest, or the internet connection was inconsistent that day for the music, so I had to wait another day.

Spyware Stop

I bought this software about a year ago. I would use it about every day. After every scan, it was usually the same cookies and not spyware very often. The problem with it is that the files that returned after the scan were unfamiliar names. Some of them, I could tell what website they were from, and some of them I couldn't tell. It was free for the first week or month as a trial version and then I purchased it. Then later I realized that Windows Vista already has spyware software in Windows Defender. Every time I ran Windows Defender, It said that it didn't find malicious software. I'm not sure which software is more reliable. www.SpywareStop.com

John Smith error messages

I knew how to do some things. The first error message I got was that the password, P0ssw9rd01 was incorrect when I tried to login as John Smith. I logged in as administrator and changed the password so I was able to login as John Smith. I ran the first script in my account and the second one in John Smith's. I got an error message while trying to edit the biography file that said "cannot create the M:\jsmith.txt." I realize that part of the problem was that I needed to be logged in as an administrator and running commands as an administrator. I had another error message saying, "only an administrator may copy to the C: drive" and that I had to have permission. I thought that moving the file to another folder or drive would make a difference, but I saw that it didn't.

RAID 5

This kind of storage is useful for correcting errors on the disk. The space available is determined by the number of disks and space available.
