Hi,
I've owned my PC (custom built) for about 2 and a half years now, and have had no problems with it. Recently it has been crashing a lot, when doing things i used to be able to do just fine. For example: rendering a video in 720 or 1080p from Sony Vegas 9, or running too many tabs of games (e.g if i play COD, minimize and do something else like jump on skype).

My specs:
Radeon HD 4870
AMD x4 II 3.1ghz
4gb ram
ASrock motherboard (not sure of model)
650watt powersupply.

I've downloaded speedfan and the temps are regular to what they have always been around. I also tried whocrashed, however for some reason it cannot pick up any crash dump files.

Any reason why this could have just started happening? Thanks

Edit: my CPU goes to 100% when this happens, shortly before it crashes. As i said its recent so i've never seen this happen before.

Is there a way to do a strain test for PSU before i would start spending any money on that?

Your specs seem to infer you are using Vista x32. If you are using Windows 7 x64 then that could be the issue especially with Sony Vegas 9.
So, what is your OS?

Basically, though, your system and rig is not exactly Windows 7 x64 fast, so you shouldn't be doing too many mulit-tasdking projects all at the same time, it would impact on the CPU and the ram causing excessive memory requirements. Don't open all those tabs, not more than 120, and don't have skype running while you are rendfering a movie.

I'm running windows 7 x64 but the thing is, this computer has never crashed, ever, doing any of these things. And its getting worse. Its starting to crash more often and when using less programs at once. Not just the ones i listed too. Even a game like minecraft on low settings will crash which is ridiculous because it's never even lagged on max settings (with nothing else open at the same time).

How much free space is on the hdd? You do need about 25% free space.
When was the last time you checked for dust on the motherboard, in the PSU, and the internal fans?
Dust is a big factor that causes many problems. It seems that 25% of PC problems are due to dust getting in the "spokes".

Oh boy well my HDD is very full. My external is 1tb/1tb and my internal is 315gb/320gb. Could that be a problem?
I've cleaned out the entire computer of all dust and made sure that wasnt causing any problems.

A full hdd is a judgemnt for disaster, the OS uses the furtherest point away from the data to use as temp storage, virtual memory etc and if it has to fight for space, the system will perform rather slowly if it all.

Uninstall any games or apps not in use, move any files to external drive that you want to keep but do notuse often.

The problem with anearly full OS hdd is that it will take a really long time to move files from it, you'd need to do only a few gb's at a time rather than one whole batch, and the time could extend to as much as 4 hours just to rid 60gb of data.
The more space left over means the hdd will perform better and you'd be able to move larger volumes faster. Always best to copy data to external drives then delete the original rather than using the Move command.

Disable indexing on all drives other than the OS drive but if the OS drive is SSD you could also disable indexing on it as well.

The thing is if you use IE9 , each time you open a tab a new iexplrer process begins (tabs are new pages in reality) however, when you close the tab, the process does not close, you will notice a long list of iexplorer process in Task Manager. A glitch? Most likely. A fix? None other than End Process yourself of the ones you think should be ended. How do you tell which ones need to be ended? Danged if I know, I think the ones that are still climbing in size but still working it out. Doe sit fix the issue by End Process yourself? Sometimes if you close the right one! How else to fix the issue? Log off then Log on.

What can you do to avoid the issues?
Don't have too many apps running at the same time, do rendering from a cold boot and only do it without the other apps running. Skype with cd in background is fine but not with much of anything else. Youtubing might be okay but only one opened at any one time.

Basically, too many apps running takes up way too much resources, only if your PC is comparable to HAL the super computer could you do it without issues :)
