Game freezes before mojang screen

[Hazrock]

Launcher Version: 1.0.1.3

Operating System: Windows XP 2002 edition service pack 3

Java Version: 1.7.0_04-b22, also tested with 1.6.0_35-b10, error log otherwise identical.

Antivirus Program: Avast!

Description of Problem:

Vanilla minecraft runs fine, but tekkit freezes for me before the mojang logo appears on screen. I am not using the "latest lwjgl build" option. Deleting META-INF in jinput.jar let me run tekkit flawlessly, but only once. (these were both suggested solutions in the "common problems and solutions" tread)

I have since tried wiping the whole .techniclauncher folder, clearing the cache, and re-installing, then deleting meta-inf again. I even tried copying the lwjgl jars and natives folder from my vanilla install over. nothing worked.

Before this, just in case it is related, I got the "could not authenticate account" error for the technic launcher, but not for vanilla, until it miraculously started going through.

Also, my graphics card is a NVIDIA GeForce FX 5200, just in case it is necessary for those "pixel format not accelerated" errors below. However, vanilla minecraft runs fine on this same hardware.

Error Messages:

none, just a white screen.

Edit: got rid of the stupid "'s

[Hazrock]

Update: tried running under jre6 & jre7, no success. :/

[Hazrock]

Update: it seems that the game will randomly start up normally, but only occasionally.
