Computer Crashes on startup

[scott2k]

Hello I was hoping I can get some help I have an acer aspire z5751 pc.
A while back the pc randomly crashed on startup this happened a few times since then we installed a new ssd drive and fresh thermal compound, however the problem still persists on the morning the pc can crash anything from 2-9 times and then will run fine all day without a hiccup and won't crash again but then the next day the same will happen again.
thank you for any help idea's or advice.

Scott

When you installed the new SSD, did you reinstall a fresh copy of the OS or did you clone the existing drive? With it crashing multiple times then running fine the rest of the day it makes me think a software issue. What kind of crash is it? Are you getting the blue screen? Does it just shut off or reboot?

thank you for you answer To be honest it was doing it on the original hdd this is we why decided to upgrade to ssd to see if this was the issue also it was a fresh install of windows 7
As for crashing sometimes it will freeze with the password screen on others a black screen and every so often it may throw up a blue screen.

scott2k, you may want to run Seatools on the drives to make sure they are not the culprit of the problems you are facing.

It could be any number of things. Though not completely ruled out yet, for the moment I think we can skip over the drive since you've replaced it and have a new OS install. Could be bad memory, a motherboard, even the PSU. If you can, check the event viewer. There might be an error logged at the time of the crash that can shed some light. I don't think it's a thermal shutdown due to the described situation.
