Ok let me run my specs first. Abit NF7-S series mobo. AMD Athlon 3200+ ATI Radeon 9800 pro Ethernet card Powersupply im not sure Lite On 52x24x52 CDRW A floppy drive 2 hard drives, dont ask why but i dont even use the one but my comp wont run without it. 4 fans OK, so my computer turns off every now and then and goes to the boot up screen but doesnt boot windows. But if i shut my computer down for awhile it will let me back on for awhile. Longer i leave it the longer i stay on. So i thought it was over heating. My CPU temp: 132 F My Case 109 F I read the post that said 140 is normal for CPU but how do i lower the case,i mean got 4 fans in this thing, could it be a power supply?
