I'm looking for a mod-pack that is literally just Tekkit with ICBM and Flans Mod. Any suggestions?

This may be a driver issue. It was for me. Go to your control panel. >Hardware and Sound >Devices and Printers >Double click on your device >Click Hardware >Scroll until you find your GPU, Then double click it >A window will pop-up. Click Change Settings >Another Window will pop-up. Select Driver >Click Roll Back Driver. The program will freeze for a minute or two. Next you screen will switch off and then back on. Once the window is unfrozen click OK. You should now be able to open the mod-packs, but I recommend you reboot first.
