Windows 7: Sony Vegas & Photoshop

Hey fellars. So first off check my specs, you're going to see that my computer could run these programs with 1/25th of it's capabilities. Now recently, my whole computer has gone to shit, gaming and everything. But that's a different thread. I am going to buy a new GFX card and PSU but, what if I buy that and this problem still persists?

So this is my problem, in Vegas , well there is no other way to put it. I honestly cannot use this program it is so slow, when I want to put a video file on the track it takes about 5 minutes to select it, and about another 2 to actually put it on the track. When I select a video FX it takes SO long to move everything. When I add text, and type in something it takes about 45 seconds for ONE letter to show up. The same problems pretty much in Photoshop.

Now I have updated everything with Vegas and PS and even everything on my computer, I have also tried setting the priority to "high" in the task manager but that does not help.

The general basis guys is I need to use these programs a lot and I haven't been able to use them these last three weeks and it's going to mess up my career.

I'll take any goddamn advice, please anything !

Sorry but if you know you have a couple of hardware problems with your PC would it not be prudent to fix those first and then test your two programs for performance. An iffy PSU will certainly cause slowness.
EDIT
Have just read your previous thread here;
Reformat
It doesn't indicate that that problem has been resolved. What's the situation as far as that problem is concerned?

Have looked at all your other posts now and they all refer to the same basic problem, slow performance which seems to be a hardware problem but all of the threads remain open ended, you haven't said whether the last suggestions made to you worked or not so it is difficult to know where to start.
Also if your PC was bought in November last year is it not still covered by a guarantee or warranty? If the PSU is faulty as one of your posts suggest should this not be replaced by HP?

Yes it is still under warranty. I guess my next move would to give it back to them, what should I tell them though, a faulty PSU?

If I were in your situation I would, first back up all of my data files then restore the machine back to the original factory settings which I believe is a feature available in an HP machine and see how it performs with the pre-installed software that came with the machine. Try using Windows Paint or similar. Then report your findings to HP, If the machine is still slow you could suggest that you think it might be a faulty PSU but they will need to check that themselves. Look at your warranty, is it a RTB (Return to base)?

I'm not sure what kind of warranty I have, all I know is I have one.

And I have tried reformatting, well and this is a thing I'm not sure of. I have a recovery disk but I'm not sure how to use it with Windows 7 because this computer originally had Vista. So when I say I've been "reformatting" I mean I've been using the upgrade disk. So I don't think it's a legitimate and complete "reformat".

To save getting too complicated, just uninstall the programs you have put on the machine, back up as I suggested before and assuming that your upgrade to Win 7 was from the free one offered when you bought the machine contact HP and point out the problems you are having and what you think is wrong. No need to mention what programs you had installed earlier!

I really didn't understand what you meant here.

Just un-install Sony Vegas and Photoshop and any games you have b=installed on the PC. Then backup your data files if you have any. Then contact HP or the retailer where you bought the machine and explain your problems and suggest, if you wish that you think it might be a PSU problem and see what they say!
