my compaq desktop will not allow me to load past the splash screen. issue occured this morning after reboot. computer was on standy through the night and when awoke this morning, it was laggy so retried. when rebooted the computer loaded very quickly to splash screen. waited for about a minute. nothing. pressed f2 and f10 and still nothing. manually powered down computer and rebooted, this time holding down esc key to access bios. nothing. it just instantly loaded to bios and was stuck there. i than powered down and unplugged hard drive and rebooted. instantly rebooted to splash screen. no errors about hardware unplugged or not found. no black screen with cursor blinking. nothing. just the splash screen. now i have been asking around and been suggested it may be bad ram, bios issues. power issues. overheating?? i personnaly have tried to rule out as much as possible. the power issue doesnt seem to be, im not recieving any errors about power and the light on the back of the tower is solid green. overheating i have tried to rule out based on all fans running smooth.. theres no loose cables anywhere. im down to ram or bios. im not a professional and would greatly apperciate any suggestions or ideas. thanks ahead of time.
