Blue screen

[Mr P]

Hi guys,

am having a problem with my computer which i assembled in person . Its specs are processor: celeron D 2.8Ghz, motherboard:  Conroe945G-DVI, RAMs: 2*512MB, graphics card: sapphire X1950GT (ATI radeon, 512MB), harddisk: SATA 250GB, and a DVD rw. ( I upgraded the bios to 1.9)

 

My woes started this summer, thats when all of a sudden i got a blue screen and at first wasn't a big deal since it was the first time. Right now am tired of diagonizing and thus need help.

 

At fist told me that " KERNEL_DATA_INPAGE-ERROR<BR>

lastly beginning dump of physical memory.

 

I removed one RAM and worked with one, then the other and found out that one wasn't working. I returned the good one and returned the other since the warrant was still on.

 

Today it brought the blue screen again. According to the problem above it can either be;

 

1.Bad memory

2.a bad processor

3.incorrectly terminated SCSI device

4.Corrupt PAGEFILE.SYS file

My question is where do i go from here, am worn out. Give me new ideas on what can be wrong. Also this appeared after getting off safe mode, which did not make a difference. But right now its working. How long it goes on like this i dont know, all i want is a depedable computer.
