|You told us absolutely nothing regarding system specs or why you went to the extreme of doing a factory reset. A reset should be done as a last resort after all other fixes have been tried. And once a reset it done, a lot of work is required to update Windows, update the drivers, reinstall all your programs, tweak Windows for best performance, etc. It generally takes several hours. The fact that your BF couldn't find something as simple as graphics drivers tells me he's not very adept at this stuff. There are only 3 major graphics providers - AMD/ATI, Intel, & NVIDIA. All he had to do was go to the respective website & download the correct driver, however, he would have to know the exact make/model of the graphics card (or onboard graphics). If he didn't install those drivers, I suspect others are missing as well. Windows generally loads generic drivers to get you going, but specific drivers from the hardware manufacturers should be installed to get best performance from the system. Drivers are required for the motherboard chipset, graphics, audio, network, wireless, bluetooth, etc.|
The beeping is a clue to your problem. The number, duration of beeps (short or long), & beep pattern is a code to exactly what the problem is. The fact that it IS beeping is a fair indicator that both the board & CPU are OK, so more than likely the problem is either the RAM was knocked loose or the video card isn't fully seated in its slot. If the card was removed & the beeping continued, the RAM is probably the issue.
Please post the system specs in detail - make/model/model numbers of the board, CPU, RAM, & especially the graphics card & power supply. And when giving the power supply specs, please don't just state the wattage, we need to know the amperage specs on the +3.3v, +5V, & +12v rails. If you don't know, look on the label on the side of the unit.
