Windows 7: Windows Boots up really SLOW

15 Jan 2013   #1

Windows 7 Ultimate 64bit
Windows Boots up really SLOW

OK so this is my buildup story that triggered this issue:

My windows 7 ultimate x64 was running perfectly well and fast until my Powercool 80 plus 7500W PSU burst (died) i then got a replacement Crosair CX600 600W. I installed the new PSU then power up my PC, It is then when i discovered it takes forever Windows to boot up, and mostly it does not boot up at all.

I am suspecting some sort of Hardware damage caused by PSU burst.

Checked my RAM on different PC works fine
Checked my Graphic Card on different PC works fine

Any suggestions....?
Any help will be much appreciated

Im wondering if the PSU has damaged the HDD. Are you running a traditional SATA hdd? Or a SSD?

If it's a Traditional Sata HDD, try running CHKDSK /r in a command prompt, It will then ask you to reboot your pc for the check disc to take place. Go ahead and reboot. The Check Disc will then start. Let it run through, Keep an eye on the screen to see if it mentions bad sector(s)

Have you checked msconfig to see if you have a ton of crap set to start up when windows boots?.

Try a check on your HDD
Hard Drive Diagnostic Procedure
could also try Troubleshoot Application Conflicts by Performing a Clean Startup but given the circumstances its likely to be hardware

That error code suggestions a possible problem with your boot manager, could be because of cirruption or problems with your disc
