I have Windows XP SP3, Intel Pentium D Dual Core 2.8 GHz, 250GB Seagate HDD, 400W iball SMPS,ATX form cabinet, 1GB RAM, 96MB onboard graphics. I have no graphics card. I have 15 mins backup UPS.
I wasn’t doing any resource intensive task on my PC. Whenever I work on my PC, after some time (say 10 mins), my PC turns off automatically. Even the UPS turns off and turns on after that. There’s no power cut when this happens.
So why this happens?
