Hi All, Here is my system; Intel Duo 1.8 1GB 5600 DDR2 (one stick) GeForce 7600GT PCi Express MSI P965 Neo (Mobo) Hiper 450w PSU 1 x Maxtor 40GB IDE HD 1 x Seagate 80GB IDE HD 1 x Samsung 160GB SATA HD I have random resets particularly when using 3d apps/games. Also on occasion when watching DivX movies/Episodes. Now, before you say Heat!, I have monitored my system carefuly and the cpu never goes above 45C and the GFX above 55C. I have recently upgraded the power supply to a Hiper 450w as initially I thought this may be the root of the problem. The resets themselves are the equivilent of a hard reset, i.e. signal message from monitor e.t.c. restart e.t.c. Medieval 2 and Oblivion are prime crash candidates although Civ4 even spacked out a few times so seems graphically orientated. Any similar problems? It's driving me nuts!!11. Help... somebody Moo.
