HP Probook 4520 Wont Boot?

Feb 12, 2012

I have a HP Probook 4520 running Windows 7. It had been acting funny and last week I ran the antivirus software and removed 1 virus. I had it on last night and after leaving it along for 20 minutes, I noticed programs were shutting down and then the computer itself shut off.

When trying to restart it, it sounds like a normal startup and the initial screen with the HP logo and "Press esc. for startup menu" in the corner comes up. It goes away as if it's going to continue restarting, but then that same screen just keeps flashing and it never starts.

I ran all the diagnostic tests in the startup menu and it passed all. There isn't a safe mode option in that menu.

HP Probook 6550B Forgotton Bios Password?

Sep 20, 2012

I have a HP Probook 6550B laptop that when it starts up it prompts you to login in. I do not remember my password or the security questions. It does ask for the Bios admin password but I have no idea what that is. I have tried to remove the laptop battery, and the small watch like battery under the keyboard for (30 Minutes), removed the havedrive, and still the same problem. When I remove the battery and only plug in just the power cord it does tell me that the BIOS is invalid, but when it reboots it goes back to defaults and goes back to the user password screen.I cannot get to the BIOS setup windows, change the boot device order, nothing.

Hp Probook 4530s 'No Graphics Driver Installed'

HP probook 4530S, running Windows 7 64-bit. I have an AMD Radeon HD 7470M installed. The computer isn't detecting the graphics card. Instead, it's resorting to integrated graphics, which doesn't quite cut it for gaming. [code]

HP Probook; Windows 7 Ultimate 64bit Keeps Freezing

Apr 14, 2012

I've got this HP machine a few months ago. Its the Probook 4530s.

I've formatted the harddrive and reinstalled windows a few time in hopes that it will fix this problem but it just does not seem to go away.

The windows keeps freezing for a few seconds, like the window will say "(Not Responding)" at the top...and then after a few seconds it starts working again. I checked the resource monitor and apparently the processor and memory utilization is quite low so I cant figure out why it still freezes.

Windows 7 Ultimate 64-Bit On HP Probook 4530s Stops Responding

Jun 9, 2012

My windows keeps getting stuck regardless of whatever software I am using. Every few minutes it says (NOT RESPONDING) at the top of whatever window that I have open. I checked task manager and there it says CPU Usage and Memory Usage is relatively low so that does not seem to be a problem.

I also checked Resource Monitor and there the only weird thing that I notice is the Disk Response time which is between 5000-8000ms for some stuff. I have attached a screenshot of that. I have run every HP Diagnostic tool and it doesn't find anything wrong with my laptop. I have formatted/re-installed windows on my system several times so I dont think the installation is a problem either.

Unable To Restore HP Probook 4520s To Factory Condition

May 19, 2012

i have a HP Probook 4520s (now out of warranty) and i want to bring the same to factory condition bcoz of virus issues. Now, on various forums i read there is an option of F11 for recovery manager, which is not working in my case.

1) In Disk management I can see my recovery partition (15 gb) but with no option of making it active.

2) My recovery partion is more like a folder in C: HP_RECOVERY_mountHPSF

What can be the best way to restore to the factory condition. This is a legitimate Windows 7 copy and therefore i do not want to install some other copy, also there could be issues with drivers and all.

HP Probook 4320s - Frequent Crashes / Freezing Randomly

Mar 16, 2012

My HP Probook 4320s laptop was purchased in October 2011 - It quickly developed the extremely annoying problem of freezing / crashing. I called the company that it was purchased it from, they asked me to do a memory test & hard drive test - they showed no errors. They then advised me to reinstall Windows 7 Home Premium 32bit (it was preinstalled when purchased). I reinstalled it, & downloaded all of the drivers from the web (a painfully slow experience on Kenyan internet...!!). After installing all of them - it's still happening! Sometimes if left for a couple of minutes it will start to work again, sometimes it needs a reset with the power button.

Reboot And Select Proper Boot Device / Insert Boot Media In Selected Boot Device

Dec 1, 2012

I am having a problem starting my PC! I have to start it in the boot menu under the RAID option. If I do not do this a message saying "Reboot and select proper boot device or insert boot media in selected boot device and press a key.." comes up, and just keeps popping up regardless of what I press! I would try using my boot disk but for the life of me I can't find it, and as windows 7 was already installed on this computer when we got it 3 year ago, I can't accurately recall if it came with one!I am no expert on BIOS, but I have read other problems similar to this one, and know that if I don't have the boot disk or the OS disk, I will need to know that at least.I am curious if the (Hard drive) is the issue. The BIOS tells me that anything in parentheses is disabled from corresponding type menu.

"Reboot And Select Proper Boot Device Or Insert Boot Media In Selected Boot Device And Press A Key"?

Sep 5, 2011

When it crashes the cursor still moves and sometimes I can move windows around but then it all shuts down and sometimes briefly shows a blue screen of death. On reboot I sometimes get this message and have to reboot again. "Reboot and select proper boot device or insert boot media in selected boot device and press a key"It's a brand new box just built last week but no warranty and I would not even know what part to replace if it's hardware related.I've attached a Hijackthis to the post if it helps but I don't think it's virus related at all.

"Reboot And Select Proper Boot Device Or Insert Boot Media In Selected Boot Device And Press A Key"

May 13, 2012

When left alone..."Reboot and select proper boot device or Insert boot media in selected boot device and press a key"I have a new(ish) cpu that I bought last Christmas, it works great and it has not crashed on me whenever I am using it. However, when I leave it on overnight (usually when it is downloading something big), when I wake up in the morning I am greeted with a black screen with the words:"Reboot and select proper boot device or Insert boot media in selected boot device and press a key"When this happens I simply press the power button a few seconds to turn it off, then turn it on again and it boots normally. (pressing a key only results in the message being repeated)What infuriates me is that it only ever happens when I leave it on overnight so I don't know when and how exactly it occurs but it almost always does. Like I said earler, it never does this when I am using it as it works fine otherwise. It just won't stay on overnight when I need it to.

System info:
Windows 7 ultimate x64 (full retail, installed once from scratch)
Intel core i7 4200k
Nvidia Gtx 560ti
16gb RAM
Seagate 500gb hdd for OS, 2Tb samsung and 1Tb seagate hdd for storage (all internal drives; no external drives attached)
Connected via hdmi to Pioneer receiver vsx 1121 then to 42" 720p Panasonic Plasma Tv

Can't Boot, Boot Into Safe Mode Or Boot From Dvd?

Dec 27, 2011

So I have been trying to get my computer running for a few days now. At first it wasn't booting at all, it would be a black screen with a blinking cursor. I have cleared cmos a few times, turned psu off, drained charge from psu, turned psu back on and got it working that way for about 10 minutes, then it crashed. Ever since then I can't get it to get running again. I think it says something about "fatal error" and then goes on telling me to boot into safe mode to remove any new hardware. Is it a hardware problem I'm having? If so, I'm screwed, too broke The best I can get is the screen where it says run windows normally or run in safe mode. But it will just crash on either option I pick. And when I try to run from the dvd drive with my windows 7 disc it's just a black screen with a blinking cursor. I'm not sure what to do...ugh I feel like it's something really simple to fix. I left my computer sitting for a few months and havn't tried to boot it until recently, so I don't remember if I put any updates on it or not.

Whenever Boot Up Computer It Shows Advent Logo-screen / Where Can Access Boot Menu

May 7, 2012

I am running an Advent desktop PC and its stats are as follows; Intel Core i5-2310 CPU @ 2.90GHz 8GB RAM Win 7 64 bit.The problem I am having is when ever i boot up the computer it shows the Advent logo-screen where I can access the boot menu etc but then it goes to a black screen with a cursor/underscore flashing in the top left... This screen stays for quite a while and I am not sure if it stops because of a key I have pressed or just because it has run its course but after it disappears the computer goes back to the logo-screen for a moment and proceeds to boot up as normal except slightly slower than usual.It is a relatively new computer and it has no problems running at all once the boot up is complete it is fast and as friendly as ever.
