Hey i was having some problems with archiving files using WinRar whenever i try to archive multiple files into larger but fewer files using WinRar it gets around 8-20% done and then my system shuts down, it doesnt freeze or anything it just shuts down. I have also experienced crashes while burning using IMGBurn and downloading or uploading files to Megaupload. Anyone have any solutions?

I suggets to check for troubles with the harddisk and for troubles with the RAM of your pc. Sudden shut down can also be cause by a defective PSU or a overheating CPU. use a third party tool to check this (i would recommend speedfan) If this is all ok/tested , try updating your BIOS and drivers and use the System File Checker to verify Windows Files.MCSA/MCTS/MCP

I did all of those things and came back with nothing. i just had my computer upgraded to win 7 and a 3.5TB hard drive and 8GB of RAM instead of 4. Would that any way cause the problem.

I would start with the ram. Remove half of it and see what happens. If it still fails, swap the ram.Rich Why can't I be different and original like everybody else? - Vivian Stanshal

Hi, Please also try the following steps to troubleshoot the issue. 1. Boot the computer in Clean Boot for a test. 2. Temporarily disable all unnecessary hardware devices in Device Manager, such as Modem, sound card or external device. For detail steps, we can refer to the link below: Device Clean Boot If the issue persists, please upload the minidump file (%systemroot%\minidump) to SkyDrive ( www.skydrive.live.com ), then share the link to me. I will be glad to assist you to analysis the data. Thanks, Novak
