Problem with Ram or HDD

[Valts17]

I have problem, sometimes Vista gives me a "Blue Deah Screen". It usually happens when the RAM's get full.
3 suspects
1) RAM - They fail under heavy work load
2) HDD - When ram's get full they try to share workload with HDD and then HDD fails
3) Vista

After i get Blue scree he makes that Dumping Physical Memory thing. After that PC restarts and i'll get Disk Boot Fail Insert Boot Disk. HDD is 4 years old and RAM's are 1 year

PC itself:
Motherboard - Asus M2N-E SLI
RAM - A-Data 2x1 GB 800mhz
HDD - Seagate 120 GB
Video - Club 3D 3870
Power - Antec 460w
CPU - AMD X2 5600+

Download a copy of memtest86 and run it for a couple of hours. You should have no errors, even one means your ram is foobar (obviously try with just one stick if you get errors and try different ram slots too if you get errors)

Make sure your hdd is plugged in correctly - no loose cables. Hdtune will run a scan of your disk to give an indication if it's healthy:

On the bright side ddr2 and hdds are cheap these days
