Hi this is my first post but I need help.
I bought a new computer last year or so.
It's always frozen completly all I can do is hard reboot it.
I took it back to the shop it came from but they say theres no problem with it.
I then bought a graphics card cause I thought it was that but it made no difference.
Then the harddrive started ticking and eventually died (I lost all data as I keep no backup
)
once the new hard drive was installed and vista reinstalled the problem continued.
I ran memtest86+ but no errors.
It happens most when watching video but other than that it can be idling and freeze by itself or even just while browsing the net.
Any help must appreciated!
Thanks in advance!

OfflineHi, well, this is my first post, too.
If your Hard Drive died, I am pretty sure that it is not a problem with any things like your video card, memory, motherboard, etc.
The PSU may need to be upgraded. The PSU is one of the most under-estimated things in a PC. All PC now should have at least 300 W. If your PSU's power is lower than 400 W (since your system requires much more power), then that may be your problem.
Does this happen when you are watching videos that are online or *any* videa (like a DVD)? This could be a network problem which you could test by not being connected to the internet…though you could run into some hangs from the computer waiting on a network resource that isn't there (this will time out though).
Make sure you don't have any malware or virus's. Along the same lines, make sure you don't have multiple real time protection software as they might be locking up your computer if they both try to block each other.
When you say your computer freezes…do you mean it is entirely unresponsive?? Can you bring up Task Manager (Ctrl+Shift+Esc)?
Zomodo is absolutely correct about PSUs. They are the most failure prone piece of hardware in a computer. You need to make sure you have a good PSU and also make sure you are using the connections correctly. Most modern motherboards have extra power connectors for the CPU and Graphics Card. If you can provide a link to your MB and Graphics Card that would be helpful.

OfflineI'm glad to say I think this issue has been fixed!
Have upgraded to windows 7 and have not frozen since! 
Seems it was an incompatibility between hardware and software all along.
But I'll answer the questions anyway:
It will (would) freeze running any video even if it's a dvd.
I'm sure it's not viruses cause it continued straight after being reformatted.
I only run avast as real time protection.
It becomes completely unresponsive as in can not do anything.
