Hello everybody, I'm having a problem with my computer and don't know much what to do. I've searched also on google and didn't get much feedback on my problem. So if you could please help me with this problem it would make me grateful. I'm getting the BSOD with the error stop 0x000000f4 ( 0x00000003, 0x899d3580, 0x899d36f4, 0x806057d6) over and over again. I've tried many things....like completely formatting my hard drive, complete virus check, installed windows from many sources and running the chkdsk utility from windows(it appeared some bads,fixed the errors ), checked my RAM with MemTest86+(said it's ok) and still having the problem mentioned and don't know what to do anymore....I'm overwelmed by it as I'm trying to learn AutoCad and some web designing and can not continue working because of the multiple restarts of the pc and windows crashings. I forgot to say that....also my hard isn't detected at the first start up and it is solved while I unplug and enter back the power cable of the hdd. I have the following configuration of the system: Windows XP Pro SP3; Dual Core Intel Pentium D925 3000Mhz; ASRock ConRoe 945G-DVI; DIMM4: GeIL CL5-5-5DDR2800 5 2 GB DDR2-800 DDR2 SDRAM (5-5-5-15 @ 400 MHz) (4-5-5-13 @ 333 MHz) (3-4-4-10 @ 266 MHz); Bios type: AMI(09.12.2006); NVIDIA GEFORCE 9600 GT; WD Caviar Blue 500GB WD5000AAKS. I hope that you can give me an answer or a tip of what could it be.Thanks!
