Weird problem... need help!

[youpla]

I am having some serious problems with one of my PC.

The troublesome PC configuration is as follow:

XPC SD31P, Pentium D945 3.4GHz, 2Gb of RAM, 250Gb SATA HD, 7800GT video card and a new 400W PSU.

A couple of weeks ago my PC started to emitt repeated beeps and shutted down right after. So I decided to change the PSU and it seemed tohave fix the problem and the PC was running fine until today.

When I switched the PC on in the evening, first it didn't start anything... pressed the reset button and PC posted, passed the BIOS screen but then got an error message telling me that there was no system disk!

Switched the PC off and on again and same problem... no system disk!

So after I switched the PC off I also switched off the PSU and unplugged the AC. After 2 or 3 minutes plugged it back, switched on and then PC started normally.

But after 10 minutes of playing a video the HDD light remained illuminated but couldn't hear the HDD doing anything and PC froze.

Powered down and restarted, checked the system and did some system est in everest, HD benchmark, memory benchmar etc... and everything look ok.

So I started playing another video and again after 5 to 10 minutes video hung and PC froze...

Any idea where I should look into? I was able to play video yesterday without any trouble...

Could it be hardware failure of some sort?

The temps are as follow:

CPU: 48C

HDD: 52C

GPU: 56C

System: 54C

TIA

Sounds like a failing hard drive.

If you have smart enabled try and load it up and use speedfan see what it says

Just as an initial thought, I would backup anything or everything u have on ur harddrive - just incase it IS the harddrive. And of course if u test stuff and windows screws up - u won`t be as upset as u could be.

As long as that psu is a good solid one, 400W should walk that system. However u could try disconnecting ur optical drive, which could give u anything up to 20/25w back, and see how it goes. Also be sure u haven`t got too many devices branching off 1 molex length, some psus don`t like it. HD->Optical->GFX sometimes will hamper one of them if suddenly the GFX wants a bigger draw.

1 thing I`m almost sure I`d check if I had ur system here, is to take out one of the ram strips and try again. Also run memtest from dos to be sure 1 or both of the strips are definately ok. Seen this mess a system so many times that u have to check it as 1 of the first considerations to not waste ur time checking other stuff first - memory is used by almost everything. If u have an issue, cutting back on an oc `might` solve it.

thanks for the advices guys, I am going to make a backup ASAP and probably buy a new hard drive soon. I will also check the RAM just in case!
