I've spent the past week trying to fix my pc myself but I'm completely stumped and have managed to make matters worse. I hope there's somebody here who can help me.
For the past 3/4 months my pc has refused to wake up when sleeping. When I hit the keyboard to wake it up, the cpu fan comes on full and there is no display. The only thing I could do was turn it off at the power button. However, when I tried to turn it back on again the problem with the fan & no display remained.
At it turned out it wasn't just sleep that caused the the problem. If I tried to turn my pc back on soon after shutting down it would also have the same problem. I had to wait at least 30 minutes before I could turn it back on again and it would be completely normal when I did so, no errors or anything.
Restarting the pc doesn't cause any of the problems mentioned.
When I shut my pc down by mistake earlier this week I tried to turn it back on a couple of times but the the problem remained. It got to the point where I took out most of the components and reseated them just to check they were in properly, took out the sata cables and then put them back in (probably in a different order to how it was beforehand) and tried different combinations of components to see if any of them were causing the problem. I probably turned it on and off at the power button too much at this point.
When it eventually turned on, the fan and display were working fine but it would freeze at the Windows logo screen (Windows 7 64-bit, just as the red and green colours come into view) and I was taken to the startup repair which couldn't fix it.
At this point I used system restore which ran through successfully the first time but it was still freezing at the same point.
Since then I have ran through many different commands and programs to try to fix the problem but I'm still unable to boot. Any help would be greatly appreciated.
List of things I've tried with the help of HBCD but have had no effect:
Built in Startup repair -- cannot repair automatically
Startup repair from Windows 7 installation disc -- disk not compatible
Reset bios by removing battery -- no effect
removed gpu and ran from integrated graphics -- no effect
chkdsk /f --No problems found
chkdsk /r -- No problems found
bootrec.exe /fixboot -- Success
bootrec.exe /fixmbr -- Success
Windows memory diagnostic tool -- No problems found
Memtest86+ -- No errors (1 pass)
Safe Mode -- freezes at classPNP.sys
Ran error checking on drives via HBCD -- No errors found
sfc /scannow -- doesn't work during system repair
- [ ] sfc /scannow /offbootdir=c:\ offwindir=e:\ windows -- Windows Resource protection did not find any integrity violations (drive letters were messed when cables were changed and seem to change every time I turn on pc,as does the drive boot order in the bios settings)
Edit: If a mod could change the title to "Desktop PC freezing during boot" that would be great. Thanks
