Computer freezes on startup.

Specs: Windows vista
My families HP Pavillion desktop computer was running slow so i reformated it to factory settings. Shortly after installing the router and wireless router antenna the screen looked like this:

now every time I start the computer about one minute after logging on the screen will "freeze" in a diagonal pattern. It looks like the pattern is taken from part of the screen just before it froze. i can open the disk tray when its in this state. the only way to get past it is to hold the power button and restart the computer. sometimes i get about 3 minutes, and sometimes the problem happens mid-log in. The computer is running 32 bit vista. If i boot into safe mode it doesn't happen. The computer is at least 5 years old. Will reformating it again possibly fix this? I fear it will freeze during the reformat and permanently screw the computer up. Do you have any ideas that might fix this problem? Thanks.

Seeing as you say that this doesnt happen if you boot into safe mode here is what i would suggest:

in safe mode goto

Start > Run type msconfig and press enter

from the window that pops up go to the startup tab, deselect EVERYTHING, dont worry Windows will automatically enable everything it needs, and you can also enable everything again if you need to later.

After you deselect everything, press apply then ok. now you will be asked if you want to restart the computer, press yes, and restart.

if the problem does not appear after restart then that means that an application you have installed is causing the problem, basically when windows loads, it will load a particular application and that causes the machine to freeze.

you will then have to find the culprit by enabling apps one at a time. to be honest i usually turn them all off, apart from my antivirus and firewall.

Anyways, try this first and let us know what happens.

I disabled all startup programs but the problem still happens just like before. From the research i've done on this the only thing i can think that is causing it is the graphics card going bad... but from the pics i've seen that doesn't seem to be the case. yeah, if safe mode works fine then it must be a program doing it. I dont think its an overheating issue.
