Lock up

I have a asus machine that runs 64 bit vista and it has me stumped right now. At first when it loaded up, it would load up with no icons and then lock up so you couldnt get to the start bar and ctrl alt delete wouldnt work. I went into safe mode and rolled it back to about 1 month previous and started it back up. This time i had my icons roll up and some of the programs would start to load up but once loaded i cant click on anything as if it freezes but i can still move the mouse around and cntrl alt delete still wont work. So ive gone into safe mode and ran a virus scan and did a memory test and all came out fine. Can someone lead me into the right direction with what might be causing this

Welcome
If, as you said, you made a full scan with your anti virus
Downloand and make a full and updated scan with malwarebytes. Report back

Here are my solutions to freezing, and an excellent article, which I hope is of some help
Go to search type device manager and look for any yellow warning markers
Download and run malwarebytes, a full scan after you update
Run antivirus scan
Check memory with memtest86
Make sure that you are not over heating.
Try in safe mode; report back if it works properly.
Try a clean boot
Make sure PSU is working properly
If overclocking, restore to original
Test hard drive at company website.
Test in safe mode, does it still happen?
Try with clean boot..

i am running the malwarebytes right now. I had did the memory test which is built in on the bios and that came back fine also. Also safe mode works perfectly fine too. it is a laptop so i dont know how you can really check overheating evern though that ussually is a main problem with them but for the case it does seem to get hot at all.

Use memtest, it takes a bit longer, but its accurate. Cant always say that for the built in test. We want to be sure when we say that it cant be a certain thing, because if wrong we will never find the cause. Good luck

If its ok in safe mode its a software problem. The malwarebytes is a good idea.

Thats what i was figureing but if maleware doesnt pick it up then i am really stumped on what software issue it is. I dont have restore disk and it doesnt have a partioned hard drive to put a new copy on so not sure what to do after this. And i spoke to soon, it just froze in safe mode...why when it freezes am i able to still move the cusor around but not click anything?

Go one step at a time, we will figure it out.
Freezing in safe mode is not good. Could be hardware.

try a second time and see what happens

when i do a quick scan it finds nothing when i do a full scan it locks up

Try it agin. Make a note of where it locks up. Then try again. Lets see if its the same location.

Well ive scanned the for malware and nothing came up that and scanned the computer for viruses and nothing for that. Ran a memory scan and that was fine too. Not sure what to do not rather then wipe it out and install a fresh copy of vista but the only problem is I dont have the disk. Its just odd that it works fine in safe mode and when u load up regular once vista completely loads it freezes. But u are able to get to a few things in the min that it loads and once loaded then freezes and you cant do anything but hold the power button down to power it off

Go to search by the start button.
Put cursor on adminstrative left column
Then look for errors at the time of problem
also try a clean boot and see if that helps.

If nothing else works try a boot log to see where the problem occurs

it is for sure now software issues....i went into msconfig and checked the diagnostic startup so it loads the basic devices and services and restarted and on load up i have no freezes and now i can navigate. Now i just have to find out what is causing the freeze...any suggestions on how to go about this?

Follow the clean boot procedure and then we have this thing licked
