external hard drive loses connection while downloading is there a problem with hard drive or usb cable?

i use external usb hard drive and download most of my data in that drive. but while downloading it loses connection sometime and then i have to re-attach it with my pc and it starts working, is there a problem with hard drive itself or the usb cable is droping connection? help me how to fix it?

Sol :-

Most of USB ports works correctly and there might be problem of USB cable which was not inserting properly in to USb ports and try it with different USB port.

There might be a problem of hard disk aswell, check it with a different port and different USB cable.

Scan the hard disk for error checking and defragment it twice in a month.

I looked all through my computer to see if I can find any of those things, so I can disable/delete them but I can't find anything. I'm not very smart with computers! /: Any help would be greatly appreciated. Thanks!

Sol :- The problem might be related to some of the signatures in windows 7 are corrupted and they are many procedures to solve this problem and problem can be solved partially and so try to repair windows 7 and if not done reinstall the windows 7.

This is better way to solve the problem.

Do I need another fan?

I just got in my new case for my computer (Antec 300) and I noticed it only came with two fans. One in the back, and one on the top. I was wondering if that was enough fans to cool my system. This worried me because there was no fan in the front

 

TL;DR My case came with a fan on the top and back but not the front. Do I need to buy another fan for the front?

 

Sol : System gets heated that is natural, if you wanna cool it. the heat form which depends on configuration which you took and if you took an high range of processor and graphic card and 3 fans is necessary for cooling of graphic card and in summer it manadatory.

 

 

 

 

 If you dont have any graphic card and high range of processor and fan is not necessary.

Before buying a PC check for the cabinet which have dual fans of side door.
