I have a problem with my computer when i shutdown and yes i do shutdown correctly. Some info, on my computer. It was custom built with phenonom x4 3400, 4 Gb kingston ram and 5850 ati graphics card. Since the computer was cutom built there was no windows, so i orderd windwos 7 premium on ebay and i bought the cheaper one that comes with no mircrosoft support i forogt what it was call oem or somthing. When got my windows i had a little trouble figuring out how to install it but, i then went into bios and changed the boot settings to boot from cd rom and it installed and works great. The problem is when i shutdown my computer for around and 30 min or more it wont boot back up correctly windows always wants to do a system restore. The werid thing is if shutdown, then start back instantly no problem or if i just always put my computer in sleep mode no problem aswell, also i can retstart as many times as i want without a problem eveything works fine besides when i shutdown for 30 mins or more then try to repower. Any idea what this is or how i can fix it?
