I've recently just built a new PC, bare with me because I know I'm a noobie! I'm a graphic designer and my computer is my bible when it comes to work, I've lost thousands of dollars in clients and also the cost of replacing the computer has been a nasty dent to my bank account. I'm only 19 =.= Mobo: GA-945PL S3 CPU: Intel Duo 3.6 ghz RAM: 2x1GB DDR2 Samsung Video: Nvidia 6600GT PCIE HD: 400gb SATAII WD, 120gb IDE WD The first time I booted the system I got the OC fail mesage. I noticed a peice of the mobo was touching the chasis, I removed it and restarted. The second time it worked and I got windows and other software installed. 2 Days later whilst in photoshop working, the computer mysteriously restarted. Ever since I've had these 3 issues: a. It starts up, leds flashing, all fans spinning etc but nothing comes up on screen - theres no signal coming through? b. The main cpu fan just does not start at all and the pc automatically shuts itself down. I'm guessin this is because the CPU is overheating, but why? c. The computer starts and in POST i get OC Fail - Please enter setup etc...I haven't overclocked the system at all. Sometimes it freezes here, sometimes it lets me into bios. Sometimes it freezes in bios and some times it doesnt. I load failsafe defaults and restart but get the same problems! What's happening here??
