Hi, I am Samyak Veera from U.S.
My dell computer is like 6 years old its been working fine till it starts saying strike f1 to reboot, strike f2 for setup utility. Please suggest me best solution for solving this problem.
Most likely your hard drive has failed. Check the system setup - F2 at powerup. If there's no hard drive showing, you'll need a new one.
If the hard drive does show up, power up, press F12 and run an extended diagnostic on it.
If you need further assistance, please post the system model information.
