hey guys, im gonna try to keep this as short and to the point as possible. my daily workhorse is an acer ax1700-u3700. recently while working on it i got a long constant beep tone which i know normally may indicate an issue with memory but after a shutdown and reboot it worked fine. few days later it began to freeze up and upon reboot was taking me to the AMI boot screen and the message at the bottom of the screen said bad checksum which i assumed couldve been a bad cmos battery so i popped a new one in and it was all downhill from there. after that the pc froze maybe 5 mins after booting. it froze in normal and safe mode and then eventually would no longer boot normally. so now if i tap the F8 i can get to the boot screen and select safe mode etc BUT it will not enter any of those modes. it takes me directly to the startup repair/start windows normally screen where neither option works. i have tried almost everything to resolve this. i have tried to run startup repair from 3 different windows 7 installation disks and 9 out of 10 tries it wont even load the disk and when it does and i am able to click on repair my computer it just freezes. i have also tried my avg rescue disc which didnt resolve the issue either. i have tried multiple times to reset the bios by switching the jumper to no avail. im just totally stuck now. i pulled the video card and memory sticks and started it up to see what beep tones i get and i got the long constant tone which im told means that the MB is in fact in tact so at this point im assuming its an issue with the BIOS. any help you guys can provide would be much appreciated. please keep in mind i cannot post any logs etc bcuz i cannot get into the machine to do so. thank you.
