Win 7 Machine Crashes under Heavy Disk Usage

[sriggs]

I have a Windows 7 machine, used as a Home Theatre PC, which crashes under heavy disk usage. I notice this: 1) when multiple torrents are downloading at once or single large (15GB+) torrents are downloading, 2) when transferring a large (ex: 50GB+ backup file) file to the machine

The machine just crashes and I get no output from the video card, no beeps, nothing. (Cannot be pinged either)

- Running Win 7, files are transferred using windows filesharing to other windows PCs.
- Torrent client used is uTorrent
- All drivers for the motherboard are up-to-date (including network, chipset, etc.) although last versions all released 2+ years ago
- direct connection via onboard lan to the network
- machine has 4HDDs but it doesn't seem to matter where I move data to, it crashes all the same
- have performed a memtest and a standard windows HDD scan, no issues

Hardware is:
- Mobo: ASUS P8H77-I
- i3 2100 CPU
- Corsair Vengeance CML8GX3M2A1600C9 8GB (2x4GB) DDR3
- PSU is a 450W Antec Neo Eco 450C

Have tried just about all I can think of short of changing out hardware... any help would be MUCH appreciated...

Can you use Core Temp software to monitor the system's temps and see if that is the culprit? Four HDD's in a small system is at high risk to overheat.

The temperature is very low on CPU and motherboard (starts at 35 deg C and goes up to 37 before it fails on the CPU, motherboard gets up to 36 deg C). System is a full aluminium case with a 120mm fan pulling air over the HDDs, which are all spaced out.

Any other suggestions much appreciated...

Check out the SMART Data for the hard drive.

Run MemTest+ to look for faulty RAM.
