my pc is constantly restarting on its on. there is no blue screen error there are no mini dumps either. it just turns off instantly then restarts. it got to the point it wouldn't even get past the windows 8 logon screen. I changed the power lead and now it stays on for at least an hour before restarting. I contacted leader computers who built my pc and they are trying to tell me its a Trojan or virus. well I have run malwarebytes pro which is also running in the background. I have run Kaspersky done spybot and also jumped online to housecall all showing nothing. I am thinking its a hardware issue casuing this to happen. My event viewer is constantly showing the same critical error
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

any advice would be good please as if its hardware I will make sure these guys fix it and not try to pass the buck and blame it on a Trojan or virus
