FIRSTLY if you have warrenty use it if not use the following steps .Open up your computer DONT TOUCH ANYTHING INSIDE , discharge yourself by touching an unpainted surface then proceed, turn on the pc Sound can vary one way that you can determine the source of noise is stoppping the fans whilst it is on one by one to determine the source.you can remove the cd /dvd from any optical drive (dvd cd drive) .And 2nd you could tell if the hard drive is crashing if you hear a reoccuring clicking sound or a whirr of which the hard drive is crashing.Depending on your manufacturer of hard drive download their hard drive diagnostics program and check for bad sectors if there is an increasing number of it occuring then your hard drive would definately be in trouble.Any sign of this vibration can be caused by vibration so try to keep all the screws tightened .

shutdown is due to overheating there is a sensor inside every processor to protect it from overheating nd if the temperature goes above this temperature it automatically shutdown. if you are using a desktop then change your cabinet buy a airy one with extra fan installed in it. or you can open one side of your cabinet to sink the heat quick;y.
it really depends on your budget and what you want to use it for. i would suggest www.tigerdirect.com or .ca if you are in canada. they have lots of sales on laptops.
prices have dropped alot recently so you should be able to pick up a good deal. i would suggest an intel processor (dual core) with a minimum of 2 gb memory. again it depends on what you use it for but a 250 gb or higher hard drive is a good start.
p.s. i've ordered a few things from tiger and the one issue i have with them is that they do a horrid job of packing items. be that as it may my laptop i purchased from there survived them shipping it and has been to australia and back as carry on and no issues.
Core 2 Duo is a Brand name by intel to identify his class of Dual core CPU
a Dual core CPU is basically two CPU in one package, which dramatically improves performance over previous architectures.
Pentium Dual Core is another brand name by Intel to identify his new entry level CPU offer.Basically Pentium dual-core are similar to Core 2 Duos except they(pentiums) are slower and cheaper. they both are dual core CPUs. I would prefer a core 2 Duo having to choose a laptop because of better performance, but the prize is different for the two solutions.
It cannot be set as desktop background... Powerpoint presentation file extention is .ppt while desktop background file extension are.. jpeg, jpg, bmp, gif......etc .gif file is the animation file. U can use the software to convert .ppt to .gif and hence set it as desktop background.
