PC Crashing

[Lydon]

Increasingly lately my PC has been crashing. It'll just turn itself off in them middle of me using it and restart itself. Today it's reached the point of ridiculousness (+-10 crashes in 4 hours).

I've found that when I switch it on in the morning after it having been off for the night, it will have trouble starting up. It begins starting up, crashes, restarts and eventually reaches the login screen after around 12 restarts. Each time it gets a little further in the process.

It's really strange. I've tried restoring to a prior date and launching startup repair, but to no avail. No viruses either. Is this a hardware or a software issue? I'm running Windows 7 RC 1.

Thanks. I'm about ready to throw it out of the window.

Disable automatic restart on crash (in XP, My Computer Properties > Advanced > Startup and recovery settings > untick auto restart) which forces you to get a blue screen of death before the PC restarts. Then write down the error code and Google it.

Also list system specs with PSU info.

when it has trouble starting up, is it before it loads the os? I have experienced a similar problem.
It would randomly restart and struggle to boot. It turned out that my tablet was faulty. Not so faulty that I couldn't use it, but if I left it plugged in, it caused all the trouble. When I keep it unplugged, no problems.

So unplug all your usb devices. Try and boot it like that.

have you tried loading it in safe mode?.. keep it there for a few hours to see if its still giving the same problem.

Ugh I feel for you. Try a system restore to BEFORE the crashing started to eliminate any software problems. Otherwise download a diagnostics program such as ultimatebootcd.com and test your CPU/memory for errors. If all diags report OK then there could be something wrong with your power supply. In all my experience, crashing was caused by faulty RAM and PSU's.

Remove all xtra cards(vga, sound, modem, lan, etc.) from pc and restart. If it seems ok, replace cards one at a time.

If you can swop out your Power supply.
Check your ram by removing it.
Clean the memory's contacts with a pencil eraser. If there is more than 1 module, boot with 1 module and then with the other.
If you have done this, you can just as well clean all fans and heat sinks from dust. You can also check in bios if your cpu is set to shut-down at a certain temperature.
Having done this and there is still a problem, use UBCD or Hirens boot cd to test ram and hard drives. Hirens hard drive will also give you the hard drive temperature in certain instances.

If you still have problems it will probably be a software issue.
If you decide to follow the above mentioned steps. pls do them 1 at a time.
My probability prediction would be: PSU, ram, overheating, vga (if agp or pci x), software(use msconfig to sort out).

P.S

If you know how a capacitor looks, have look at them. (Normally in the region of the cpu). If they are bulging or even worse leaking, it could indicate a motherboard problem.

maybe a component failure due to heat issues.Shove a iceblock in it
