Sick of politics here? Fix my computers!

I’m currently having problems with two computers. The first is a Dell Inspiron 9300 laptop. I thought initially that this problem started from a jolt it may have taken when I slammed on the breaks in my car and had it flop off of the seat onto the floor (figures, the one time I don’t secure it this happens!), but the computer did work fine for about a week and a half after that incident. What happens is when you move the computer, it will make a sound similar to the grating noise you hear when plugging speakers into a sound card. Then the computer locks up and the screen stays on, but the touchpad and keyboard are unresponsive. It got progressively worse as time went on, and occasionally it would give me an NMI: Parity error. I figured hard drive, but after doing some research I found that could also relate to the hard drive and CPU. More and more signs pointed to the hard drive. I replaced the hard drive, and still get the same problems. I’m now fairly certain it has something to do with the power supply. When I connect/disconnect the power cord it will make that metalish noise sound that I mentioned earlier and freeze up.

Secondly is my desktop. This computer seems to randomly completely shut off. I can power it back up immediately, but depending on how long I leave it off and unplugged the longer it will work. Sometimes it will go for days on days before doing this, then for whatever reason it will crash. I’m pretty sure this is a power supply issue. I feel like with the extras I’ve added on perhaps I’ve stressed my current PSU and it can’t handle everything. When it shuts off my CPU temp has been anywhere from 85 – 105 (all F) so I don’t think that it’s an overheating issue.

I guess my question is, do both of these issues sound like power supply issues? If so, what size PSU should I get for the desktop (I assume the laptop has limited power supply sizes.)? And what could cause both of my computers to die, but no issues to my roommates? Just coincidence? It’s possible that my roommates computer wasn’t plugged in at the time, but most of the time it is. I’d appreciate any insight you guys have. Thanks!

Laptop: I would open the case and make sure the memory is seated properly. My first guess is a memory module is not properly seated.

PC: I would guess overheating but if you think it's the PSU, You should replace it and see if that clears up the problem. If you arent running a gaming machine with SLI video cards then any 400Watt PSU would work. Look at your current PSU, Bump up the watts a little just incase it wasn't powerful enough.

Maybe Obama will buy all American's a computer so they can search the web on the internet that Gore invented.

Al Gore may not have invented the internet, but he was instrumental in making it as mainstream as it currently is.

Sorry but buisnesses and people who invested in the internet is what made it grow to what it is today. Gore just took credit.

Way to bring politics right into this, first.

First of all, first. Do some fact checking. Al Gore never claimed to have created the internet. Here's the link to Snopes that gives you the exact quote. snopes.com: Al Gore Invented the Internet (http://www.snopes.com/quotes/internet.asp)

Secondly, he passed a lot of legislation to get the internet publicly used. He worked on getting the internet away from being just a military thing to an academia thing to the general public.

Third of all, get out of my thread. No hijacking here. Hopefully one of those computers Obama gives people will have Mario Teaches Typing to help you with your constant spelling mistakes.

maybe that guy is around. he is the one that's pretty computer savvy

I spell so bad that I have trouble reading what I type.

Daseal, your desktop randomly shutting down actually sounds more like a motherboard issue. Is it also a Dell? We work on about 15,000 Dell desktops, mainly Optiplexes, and whenever one of them shuts down it's almost always the motherboard. A particular problem is a capacitor that blows, which is easy to spot.

Maybe you can take the palmrest plastics off of your laptop and have the keyboard attached but not secured to the motherboard to take a look at where the noise is coming from. This is assuming of course that your warranty is expired.

Have fun!
