I have been having major issues lately with my HP Pavilion DV6t laptop running Windows 7 Professional. The computer is about 2 years old and has had no issues up until about two weeks ago. At the time, I started to have trouble loading windows 7. The OS would often fail to load and generate a blue screen error and reboot itself before the windows loading screens had completed cycling through. Afterwards, the PC would typically fail to start if I rebooted it again and instead prompt me to run windows repair and/or system restore. At first, running those utilities would fix the issue and the computer would work again for a day or two. However, I found that these problems would just start up again soon afterwards and that I was eventually unable to start up windows at all.
At this point, I was even unable to even boot up safe mode. The drivers for safe mode would start to load but then the loading sequence would eventually freeze up and nothing would happen (often the computer would just crash after a few minutes). After the PC tried to prompt me to do system repair a few times after crashing or producing a BSOD error, it eventually would not work anymore and I would have no way to access windows. It would also not let me conduct system restore after going through the routine of not loading windows a few times.
After I got to this point, I decided to just go ahead and reformat the whole computer and reinstall windows from scratch. Every other option I had (such as repairing the current windows installation) was not working at that point. After I did this and re-installed the OS, it appeared to fix the problem at first. However, the computer ended up having the same issues I had in the first place where windows would not load the not long after I had done a complete reformat/reinstall. It would then again prompt me to do a system repair/system restore like I did before I reformatted the PC only to end up almost completely inoperable soon afterwards.
Since I first reformatted the PC, I have done a reformat/reinstall about 3 times only to end up with the same result. I should note that it appears that everything runs fine until I go to install the drivers for my ethernet/wireless card (which is the first driver I need after doing a full re-install). Once I get connected to the internet, the computer will crash following a BSOD error but then restart and act normal for a while. It is not until the next day (or about 12-14 hours after having the computer shutdown) that it will not boot up into windows. It doesn't seem to matter if I reboot or shutdown the computer multiple times soon after reformatting it.
I should also note that I have tried a number of anti-virus/anti-spyware programs after re-installing windows to see if that may be causing the issue. I ran superantispyware, Malwarebytes anti-spyware/anti-rootkit, Kaspersky anti-rootkit, CCleaner and Avast anti-virus but came up with no issues.
Does anyone think this is a software related issue or that this may be due to a hardware issue? I feel that the computer wouldn't turn on at all or wouldn't let me re-install windows in the first place if it was a major hardware issue causing these problems. Let me know what you think I could do to help get my PC to work again. Thanks.
