basically i've had my pc for nearly 2 years and i've rebooted it about 3 times now and it created a backup file in the c-drive and theyr like 4gb each the files. so i was wonderign if i could delete these files or not?? the first ever time i backed up it created files like 61c17c86af42465c1bb4 :confused::confused::confused: but the other backup files dont contain files like this...so wud it be ok to delete the files?? and i dunno why this happend but recently my pc after like an hour just keeps switching off.. and restarting by itself but it just goes to the window page and retsrts again so it doesnt actually switch on.. i dunno why this happend but i rebooted and it was ok for a few days but now its happenign again so what shall i do for both problems?
